This chapter describes how to use CTM to provision network services. It also details the tasks required to create new connections, and display, modify, and delete existing connections. This chapter includes the following sections:

•Overview

•Managing Circuits

•Managing BLSRs

•Managing MS-SPRings

•Managing VLANs for E-Series Cards

•Managing VLANs (ML-Series Cards)

•Provisioning Data Services

•Managing QoS Profiles

•Managing DWDM Rings

•What Is Connection Provisioning?

7.1  Overview

A metro network is a network that aggregates customer traffic and connects customers to services. The metro network is responsible for receiving network traffic from long-haul transport networks and routing this traffic to and from enterprises and end users.

The service point-of-presence (POP) performs service adaptation and packet switching. This layer performs the following functions:

•Grooming of traffic from the metro network

•Edge packet switching, where IP services are enabled

•Core packet switching, where POPs are interconnected over the IP backbone

The service POP is the hub of high-value Internet services. The core network, where optical technologies predominate, is the domain of the long-haul carrier. This high-speed transport fabric interconnects service POPs and has traditionally been built as SONET ring architectures.

CTM simplifies operations support system (OSS) integration for service providers for the end-to-end management of transport networks.

7.2  Managing Circuits

A circuit represents an end-to-end connection between two or more connection termination points (CTPs). A circuit consists of an alternating series of cross-connections and link connections. In its simplest form, a circuit consists of a single cross-connection (if the circuit is defined between two CTPs on the same NE). A circuit can be bidirectional or unidirectional, point-to-point (PTP) or point-to-multipoint, and protected or unprotected.

CTM allows you to create unidirectional and bidirectional circuits for CTC-based NEs and DWDM optical channel client connection (OCHCC) circuits for CRS-1 NEs. For unidirectional path switched ring (UPSR) circuits, you can create revertive or nonrevertive circuits. CTM can route the circuits automatically, or you can route them manually. For CRS-1 and CTC-based NEs (including the ONS 15305 R3.0), circuits can be viewed, created, modified, traced, and deleted. For the ONS 15530 or ONS 15540, a circuit is an end-to-end connection between two ports on ONS 15530 or ONS 15540 NEs in terms of lambda (wavelength). For the ONS 155xx, circuit services provide the following major capabilities:

•Finding all end-to-end connections between NEs in terms of client ports, provided the entire path was traversed within ONS 15530 and ONS 15540 NEs.

•Displaying the protection information associated with each circuit.

•Displaying all directional-based paths that have been configured and are in use for a protected circuit.

•Displaying the active and standby paths that have been configured and are in use for a protected circuit.

Note Circuit information is not available for the ONS 15216, ONS 15302, ONS 15501, ONS 15800, ONS 15801, ONS 15808, Cisco Catalyst 6509, Cisco 7600, or Cisco XR 12000. For the ONS 15302 and ONS 15305, circuits can be created through CEC (Configuration > ONS 15302 or ONS 15305 > Launch Cisco Edge Craft).

For ONS 15305 NE releases 3.0 and later, circuits can be created in CTM, CTC, and CEC. Circuits that are created in CTM or CTC can be managed in CTM, CTC, and CEC. But circuits that are created in CEC show unpredictable and erroneous behavior in CTM and CTC.

For ONS 15305 NE releases earlier than R3.0, the circuit information is not available in CTM. Circuits can be created in CEC but cannot be managed in CTM.

Note Circuit management performance depends on an efficient DCN network. Refer to the ONS 15454 user documentation for details.

The following table defines the circuit terms and options that are used throughout this chapter.

Table 7-1 Circuit Terms and Options 

Circuit Option	Description
Link	Represents a topological relationship between two physical termination points (PTPs) for a particular layer rate. The possible set of layer rates is determined by the layer rates terminated by the PTP. For example, an OC-N port will terminate a physical layer rate and a SONET layer rate.
Circuit	Represents an end-to-end connection between two or more CTPs.
Cross-connection	A (normally flexible) connection between two CTPs within the same NE.
Link connection	An inflexible (or fixed) connection between two CTPs that are contained by two PTPs connected by a link. It represents a portion of the transport capacity of a link, such as an STS-1 channel within an OC-N link.
PTP	A termination point that is the actual or potential endpoint of a link that might be abstracted as a PTP. It is the representation of a physical port.
CTP	Represents the actual or potential endpoint of a cross-connection, link connection, or circuit. A CTP is contained within a PTP. In some cases, there is a single CTP associated with a PTP, such as with a DS-1 PTP. There could also be multiple CTPs, such as with STS-1 or STS-Nc CTPs contained within an OC-N PTP.
Source	The circuit source is where the circuit enters the network.
Destination	The circuit destination is where the circuit exits the network.
Automatic circuit routing	CTM routes the circuit automatically on the shortest available path based on routing parameters and bandwidth availability.
Manual circuit routing	Manual routing allows you to choose a specific path, not just the shortest path chosen by automatic routing. You can choose a specific STS or VT for each circuit segment for SONET nodes, or a specific VC4, VC3, or VC12 for each circuit segment for SDH nodes. You can also create circuits from work orders prepared by an OSS such as the Telcordia TIRKS system.
Low-order tunnel	Low-order tunnels allow VC3 and VC12 circuits to pass through an SDH node without using cross-connect card (XC10G and XCVXL) resources. Low-order circuits using tunnels will use cross-connect capacity only at the source and destination nodes. One low-order tunnel can carry three VC3s, and each VC3 can carry 21 VC12s. One tunnel can carry one VC3 circuit span and 42 VC12 circuit spans, and each VC3 is a separate container that can contain a VC3 circuit span or 21 VC12 circuit spans.
Low-order aggregation point	Low-order aggregation points (LAPs) allow low-order VC12 and VC3 circuits to be aggregated into a VC4 for handoff to non-ONS networks or equipment, such as interoffice facilities (IOFs), switches, or digital access cross-connect systems. The VC4 grooming end of the LAP requires an STM-N card. LAPs can be created on MS-SPRings, 1-1, or unprotected nodes, but cannot be created on subnetwork connection protection (SNCP) nodes.
VT tunnel	VT tunnels allow VT1.5 circuits to pass through a SONET node without using cross-connect resources. VT circuits using VT tunnels will use cross-connect capacity only at the source and destination nodes. One VT tunnel can carry 28 VT1.5 circuits.
VT aggregation point	VT aggregation points (VAPs) allow VT circuits to be aggregated into an STS for handoff to non-ONS networks or equipment, such as IOFs, switches, or digital access cross-connect systems. VAPs reduce VT matrix resource utilization at the node where the VT1.5s are aggregated onto the STS. This node is called the STS grooming end. The STS grooming end requires an OC-N, EC-1, or DS3XM-6 card. VT aggregation points can be created on BLSR, 1+1, or unprotected nodes, but cannot be created on UPSR nodes.

7.2.3  Viewing the Circuit Table

The Circuit table shows circuit information for all circuits that make up a topology. A circuit describes a fixed-size bandwidth pipe that is fully cross-connected from one user-defined source point (node, slot, or port) to a second user-defined destination point across some number of node-to-node optical spans (zero if the circuit is local to a single NE).

An endpoint can be an actual physical drop port (DS-1, DS-3, and so on) or an STS-n or VT1.5 channel in an optical line. A multicast circuit consists of circuit spans that have one source endpoint and a sequence of destination endpoints.

---

7.2.4  Creating Circuits Using the Circuit Wizard

The Create Circuit wizard (Configuration > Create Circuit) allows you to create circuits on CTC-based and CRS-1 NEs. Use the Create Circuit wizard to create an end-to-end circuit through a subnetwork. A subnetwork is defined as a set of NEs that are interconnected directly or indirectly through links known by CTM. CTM supports circuit provisioning across a heterogeneous network. Establish a circuit by specifying the A and Z termination points (TPs). You can create multiple circuits using the Create Circuit wizard; however, for VT tunnel circuits, the number you can create is limited by the bandwidth available on the VT tunnel being used. The maximum number of VT circuits that can be routed through a VT tunnel is 28.

---

Caution When adding CTC-based circuits, examine the links in the network to ensure correct operation. If any links are down, verify that the ports are not data communications channel (DCC) enabled. For information about viewing links, see 3.6.4  Viewing the Link Table, page 3-40.

---

---

Note New circuits can be created across subnetworks. To create a new circuit across subnetworks you must first disable automatic grouping of NEs in the Control Panel. See 4.4.9  Configuring Application-Specific Parameters, page 4-55 for more information.

Note Low-order (LO) circuit options are not available for LO_VCAT circuits. Routing a LO_VCAT circuit, by selecting LO routing options to create a LAP/VC tunnel automatically, is not supported. If the LAP/VC tunnel already exists, and bandwidth is available, the LAP/VC tunnel is used to route LO_VCAT circuits.

---

---

Note When you create a low-order circuit and choose to create a tunnel automatically (by selecting the VT Tunnel on Transit Nodes option), the alias for the tunnel circuit will be the same as that provided for the low-order circuit. When you create multiple low-order circuits, the alias for the tunnel will be the same as the alias of the first low-order circuit.

---

---

Caution For TL1 circuits, if you simultaneously mark all of the NEs involved in the circuit as Out of Service, CTM loses the EMS attributes (such as circuit alias, customer ID, and service ID). If you later mark all of the NEs involved in the TL1 circuit as In Service, the circuits are discovered, but the EMS attributes remain missing. To retain EMS attributes, you must upgrade the TL1 circuits to regular CTC circuits before adding EMS attributes and marking the NEs as Out of Service. To do this, select the TL1 circuit in the Circuit table and choose Configuration > Reconfigure Circuit(s).

The following table describes the fields in the Create Circuit wizard for optical devices.

Table 7-7 Field Descriptions for the Create Circuit Wizard—Optical Devices 

Field	Description
Navigation Pane
The navigation pane on the left side of the Create Circuit wizard tells you where you are in the process of creating the circuit. The list of tasks shown initially is the default list of all possible tasks. As you move through the circuit creation, you are taken to the appropriate task. You can use the navigation pane to jump quickly from one task to the next, or to an already visited task. Using the navigation pane is faster than using the Back and Next buttons, because you can jump over multiple panes in one step versus clicking Back or Next and moving through the panes sequentially. Tip As you proceed through the wizard, the panes you have visited are highlighted in white and identified by a number. Panes that are not applicable to the current circuit creation sequence are shown in italics. Tip Click the Maximize button to expand the Create Circuit wizard. After you expand the Create Circuit wizard, the Maximize button changes to a Reset Size button. Click the Reset Size button to reduce the Create Circuit wizard to its original size.
Type
Type	Select the type of circuit to create from the Type drop-down list. Note The circuit type selected is displayed (dimmed) in other panes in the Create Circuit wizard. To change the circuit type you must return to the Type pane and make a new selection. SONET and SDH circuits have different types. For SONET circuits, values are: •OCHCC; see Creating a DWDM OCHCC •OCHNC; see Creating a DWDM OCHNC •STS (including Ethernet circuits) •STS-v •VT •VT Aggregation •VT Tunnel •VT-v For SDH circuits, values are: •OCHCC •OCHNC •VC_HO_PATH_CIRCUIT •VC_HO_PATH_VCAT_CIRCUIT •VC_LO_PATH_AGGREGATION •VC_LO_PATH_CIRCUIT •VC_LO_PATH_TUNNEL •VC_LO_PATH_VCAT_CIRCUIT Note The available circuit types are based on the types selected for the user during user creation.

For supported circuit sizes on Ethernet cards, see Cisco ONS 15454 Reference Manual, available at http://www.cisco.com/univercd/cc/td/doc/product/ong/15400/index.htm. For single-card EtherSwitch, only STS-1, STS-3c, STS-6c, and STS-12c apply. For multicard EtherSwitch, only STS-1, STS-3c, and STS-6c apply. Note The available circuit sizes are based on the size limitation imposed on the user during user creation.
OCHNC Wavelength	If OCHNC is selected in Type, the wavelength of the OCHNC is selected here. If OCHNC is not selected in Type, this option is not available.
Band	(OCHNC circuits only) Choose the band you want to provision.
Use OCHNC Direction	Choose whether or not to specify the OCHNC direction. Select the check box to allow you to specify the circuit direction (for NEs up to and including R6.0) in the OCHNC Direction drop-down list. If the check box is unchecked (for R7.0 NEs) the OCHNC Direction drop-down list is disabled.
Channel Group	Choose the channel group you want to provision (OCHNC circuits only).
OCHCC Wavelength	If OCHCC is selected in Type, the wavelength of the OCHCC is selected here. If OCHCC is not selected in Type, this option is not available.
OCHNC Direction	If OCHNC is selected in Type, the east-to-west or west-to-east direction of the OCHNC is selected here. If OCHNC is not selected in Type, this option is not available.
Bidirectional	Check this check box to create a two-way circuit; uncheck it to create a one-way circuit.
State	Select an administrative state for the new circuit. SONET and SDH circuits have different values. For SONET circuits, values are: •IS (In Service)—The circuit is in service and able to carry traffic. •IS AINS (In Service-Auto In Service)—Alarm reporting is suppressed, but the circuit is able to carry traffic. •OOS DSBLD (Out of Service-Disabled)—The circuit is out of service and unable to carry traffic. •OOS_MT (Out of Service-Maintenance)—The circuit is in maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. For SDH circuits, corresponding values are: •Unlocked •Unlocked,autoInService •Locked,disabled •Locked,maintenance
Apply to Source/Destination Ports, If Allowed	Check this check box to apply the selected state to the source and destination ports.
Protection (available for OCHCC circuit type only)
Protected	Check this check box to specify that circuit endpoints have to be selected only from cards that have embedded splitter-type protection.

Symmetric	Check this check box to create a symmetric VCAT circuit.
Member Size	Select a size for each VCAT member.
Number of Members	Specify the number of members to be configured for the VCAT circuit.
Mode	Choose the protection mode for the VCAT circuit: •None—Provides no protection. A failure on one member causes the entire VCAT circuit to fail. •SW-LCAS—Allows the VCAT circuit to adapt to member failures and keep traffic flowing after failures at a reduced bandwidth. •LCAS—Uses a signaling protocol where the members in a virtual concatenation group (VCG) can be dynamically changed without interrupting the operation of uninvolved members. If implemented correctly, there are no errors. LCAS allows the source and destination nodes of a VCG to signal to each other so that the addition or deletion of a member from the VCG can be synchronized without errors.
Protection
Protected Drops (Non-Ethernet)	Specify whether protected drops are indicated. If selected, this option restricts the set of displayed source or destination termination points to those in 1:1, 1:n, or 1+1 protection groups.
Provision Working Go and Return on Primary Path	Check this check box to provision SNCP/UPSR protection routes in a Go and Return fashion as detailed in ITU-T G.841, to avoid too long a delay on another direction of traffic. This feature applies only to bidirectional UPSR/SNCP circuits. Unidirectional UPSR/SNCP circuits are not affected and the shortest path to the destination is always used as the working path.
Revertive	Specify whether traffic is reverted back to its original path when the conditions that diverted the circuit to the protect path are repaired. If you do not choose Revertive, traffic remains on the protect path.
Reversion Time	Specify the amount of time (in minutes) after which traffic reverts back to the original working path when conditions that caused the switch are cleared. The range is from 0.5 to 12.0 minutes. The Cisco default is 5 minutes.
SF Threshold (for SONET circuits only)	Set the UPSR path-level signal failure (SF) threshold. Note This field is visible only for point-to-point topologies.
SD Threshold (for SONET circuits only)	Set the UPSR path-level signal degrade (SD) threshold. Note This field is visible only for point-to-point topologies.
Switch on PDI-P (for SONET circuits only)	Specify whether traffic should switch based on a received STS payload defect indication. Note This field is visible only for point-to-point topologies.

Routing Preferences
Route Automatically	Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. Alternately, you can disable automatic route selection and manually route the circuit where you specify all the intermediate hops on a hop-by-hop basis (up to 64 hops per circuit). You can manually route the circuit using either one of the following views: •Graphical—Provides a map view that displays the nodes and links you can use to create the circuits. You can select the nodes and links that you need for your circuit from the map view. •Textual—Provides a text view that lists the nodes you can use to create the circuits. Note If the source and destination of the circuit are on the same node, automatic routing is enabled.
Using Required Nodes/Links	(Available only if Route Automatically is checked) If checked, CTM automatically routes the circuit through the required nodes and/or links. There are two ways you can specify the required nodes and links. Choose one of the following: •Graphical •Textual
Review Route Before Creation	(Available only if Route Automatically is checked) Check this check box to review the route before it is created.
VT-DS3 Mapped Conversion	(Available only if Route Automatically is checked) If checked, you can route the circuit using the DS3XM12 card. Not applicable for data cards (ML-series and CE-100T-8 cards).
Time Slot Restriction	If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable. Note Time Slot Restriction is not available for OCHCC and OCHNC circuit types. Note For VCAT circuits, you must enter multiple STS/VC4 values in the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter in the Time Slot Restriction field cannot be identical, or circuit creation will fail with an error message.
Common Fiber Routing	(For VCAT circuits) Click this radio button to route each member circuit on the same fiber.
Split Routing	(For VCAT circuits) Click this radio button to route member circuits on separate paths.
Member Preferences	(For VCAT circuits) Specify the following information for member circuits: •Number—Enter a number between 1 and 256 to identify the member. •Name—Enter a unique name to identify the member. The name can contain up to 48 alphanumeric characters, including spaces. •Protection—Specify the member circuit protection type (Fully Protected, PCA, or Unprotected). •Node Diverse—Specify the node diversity for each member circuit: –Required—Ensures that the primary and alternate paths are node-diverse. –Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse. –Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse. The paths might be node-diverse, but CTM does not check for node diversity. •Set Protection for All—Allows you to choose the same protection type for all members. •Set Node Diversity for All—Allows you to specify the same node diversity for all members.
Fully Protected Path	If selected, CTM ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking the Dual Ring Interconnect check box. Alternately, if the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications: •Required—Ensures that the primary and alternate paths of the UPSR portions of the complete circuit path are node-diverse. •Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. •Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.
Protection Channel Access	To route the circuit on a BLSR protection channel, if available, uncheck the Fully Protected Path check box, and check the Protection Channel Access check box.
Dual Ring Interconnect	If you selected Fully Protected Path and the circuit will be routed on a DRI, check the Dual Ring Interconnect check box. Note For DRI and iDRI manually created circuits, you must double-click the DRI span for it to become DRI. A single-click does not enable the DRI span.
Diverse Shared Risk Link Group (SRLG)	If checked, fully protected circuits will be routed through working and protected links that do not share risk groups.
Conversion Route Constraints (available only if VT-DS3 Mapped Conversion is checked)
NE ID	Select from the list of available NE IDs to specify the source NE ID.
Subnetwork ID	(Read-only) Displays the ID of the subnetwork associated with the circuit source.
Slot	Specify the source slot that contains the DS3XM card.
DS3 Mapped STS	Choose Circuit Source or Circuit Dest.
VT/VC LO Circuit Options (available only for VT and VC LO path circuits)
VT/VC LO Tunnel on Transit Nodes	This option is available if the VT or VC circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VT/VC circuits to pass through NEs without consuming low-order cross-connect card resources. In general, creating tunnels is a good idea if you are creating many low-order circuits from the same source and destination.
VT Aggregation Point (VAP)/VC LO Aggregation Point (LAP)	(For SONET) This option is available if you are creating a VT1.5 circuit to a DS-1, EC-1, DS3XM-6; or an OC-N port on a BLSR, 1+1, or Unprotected node. A VAP allows VT1.5 circuits to be routed through a node using one STS connection on the cross-connect card matrix rather than multiple connections on the VT1.5 matrix. (For SDH) This option is available if you are creating a VC12 circuit to an STM-N port for handoff to non-SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix.
Circuit Source is STS/VC4 Grooming Node	Creates the VAP or LAP on the VT or VC circuit source node. This option is available only if the VT circuit originates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit originates on an STM-N card.
Circuit Destination is STS/VC4 Grooming Node	Creates the VAP or LAP on the VT or VC circuit destination node. This option is available only if the VT circuit terminates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit terminates on an STM-N card.
None	Choose this option if you do not want to create a low-order tunnel or a VAP/LAP. This is the only available option if CTM cannot create a low-order tunnel or VAP/LAP.
VLAN Selection (available only for Ethernet cards or EtherGroups)
VLANs	Select from the list of available VLANs to associate an existing VLAN to the circuit. If the Circuit VLANs list is empty, CTM assigns the default VLAN. To create a new VLAN, click the New VLAN button. Enter a unique VLAN name and ID. The VLAN ID must be an integer greater than 1 but less than 4093. Click OK; then, click OK in the Successfully created VLAN confirmation dialog box. The new VLAN appears in the list of VLANs. The list is ordered alphanumerically by VLAN name, where numbers precede letters and uppercase letters precede lowercase ones. Note Gigabit Ethernet G-series, ML-series, and E-series cards that are configured in port ML-series mode do not support VLAN assignment.
Enable Spanning Tree	Check this check box to enable spanning tree protection for the circuit. This option is disabled for intranode and multicard Ethernet circuits.

Table 7-8 Field Descriptions for the Create Circuit Wizard—CRS-1 Devices 

Field	Description
Navigation Pane
The navigation pane on the left side of the Create Circuit wizard tells you where you are in the process of creating the circuit. The list of tasks shown initially is the default list of all possible tasks. As you move through the circuit creation, you are taken to the appropriate task. You can use the navigation pane to jump quickly from one task to the next, or to an already visited task. Using the navigation pane is faster than using the Back and Next buttons, because you can jump over multiple panes in one step versus clicking Back or Next and moving through the panes sequentially. Tip As you proceed through the wizard, the panes you have visited are highlighted in white and identified by a number. Panes that are not applicable to the current circuit creation sequence are shown in italics. Tip Click the Maximize button to expand the Create Circuit wizard. After you expand the Create Circuit wizard, the Maximize button changes to a Reset Size button. Click the Reset Size button to reduce the Create Circuit wizard to its original size.

7.2.4.1  Creating an STS (Including Ethernet), STS-V, VT, VT-V, VT Tunnel, or VT Aggregation Circuit

---

Step 1 Select the node for which to create a circuit and open the Circuit wizard. For an explanation of Circuit wizard launch points, see Table 7-5.

Step 2 In the Type pane, choose STS (including Ethernet circuits), STS-V, VT, VT-V, VT Tunnel, or VT Aggregation. (Choose STS for ML-series circuits. For ONS 15454, choose STS for circuits starting and ending at a fiber channel [FCMR] card). In the Number of Circuits field, enter the number of circuits you want to create. The Cisco default is 1. If you enter more than one, you can use autoranging to create the additional circuits automatically.

Step 3 Click Next.

Step 4 In the Attributes pane, enter the following information; then, click Next:

•Name—Enter a unique name for the new circuit. The circuit name is a free-format string of up to 48 ASCII characters.

•Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

•Description—Enter a circuit description of up to 256 characters.

•Size (STS circuits only)—Specify STS-1, STS-9c, STS-12c, STS-24c, STS-48c, or STS-192c. The valid size for circuits involving the DS3i card is STS-3c. Valid sizes for circuits involving the FC_MR-4 card are STS-1, STS-3c, STS-24c, and STS-48c.

For a single-card EtherSwitch, only STS-1, STS-3c, STS-6c, and STS-12c apply. For a multicard EtherSwitch, only STS-1, STS-3c, and STS-6c apply.

Valid circuit sizes for an ML-series circuit are STS-1, STS-3c, STS6c, STS-9c, STS-12c, and STS-24c.

•Bidirectional—Check this check box to create a two-way circuit; uncheck it to create a one-way circuit. (For STS and VT circuits only; E-series circuits, G-series circuits, ML-series circuits, VAP circuits, and VT tunnels are bidirectional.)

•Number of Circuits—Enter the number of circuits to be created. For ML-series circuits, only one circuit can be created.

•State—Choose an administrative state to apply to the circuit:

–IS—The circuit is in service.

–OOS—The circuit is out of service. Traffic is not passed on the circuit.

–OOS-AINS—The circuit is out of service until it receives a valid signal, at which time the circuit state automatically changes to in service.

–OOS-MT—The circuit is in maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit.

•Apply to source/destination ports—Check this check box to apply the selected state in the State field to the circuit source and destination ports. Uncheck this check box for ML-series circuits.

•Protected Drops (Non-Ethernet)—Check this check box if you want the circuit routed on protected drops only. If selected, this option restricts the set of displayed source or destination termination points to those in 1:1, 1:N, or 1+1 protection groups. Uncheck this check box for ML-series circuits.

•Provision working go and return on primary path (bidirectional UPSR/SNCP protection only)—Check this check box to provision the working path to go or return to the primary path.

---

Note CTM currently provisions unidirectional SNCP/UPSR circuits following the GR-1400 standard. For bidirectional SNCP/UPSR circuits, you can check the Provision working go and return on primary path check box to route the working and protect paths in one direction following the ITU-T G.841 standard. Unidirectional UPSR/SNCP circuits are not affected by this new routing, and the shortest path is always used as the working path.

---

•Path Selectors (UPSR protection only)—If the circuit will be routed on a UPSR, set the UPSR path selectors as follows:

–Revertive—Check this check box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If you do not choose Revertive, traffic remains on the protect path.

–Reversion Time—If Revertive is checked, specify the amount of time (in minutes) after which traffic reverts back to the original working path when the conditions that caused the switch are cleared. The range is from 0.5 to 12.0 minutes. The Cisco default is 5 minutes.

–SF Threshold (for STS circuits only)—Set the UPSR path-level SF bit error rate (BER) threshold. This field is visible only for point-to-point topologies.

–SD Threshold (for STS circuits only)—Set the UPSR path-level SD BER threshold. This field is visible only for point-to-point topologies.

–Switch on PDI-P (for STS circuits only)—Specify whether or not traffic should switch based on a received STS payload defect indication. This field is visible only for point-to-point topologies.

•(Optional) Specify the customer information:

–Customer ID—Identify the end user of the circuit.

–Service ID—Enter the service ID of the circuit.

Step 5 In the Source pane, enter the following information; then, click Next:

•NE ID—Select from the list of available TPs to specify the source TP.

•Source—Specify the source slot, port, STS, DS1-14, and VT.

•Use Secondary Source—Check this check box to create a secondary source. Then, specify the NE ID, slot, port, STS, DS1-14, and VT for the secondary source.

---

Note The secondary source is applied to open-ended UPSR and DRI.

---

Step 6 In the Destination pane, enter the following information; then, click Next:

•NE ID—Select from the list of available TPs to specify the destination TP.

•Destination—Specify the destination slot, port, STS, DS1-14, and VT.

•Use Secondary Destination—Check this check box to create a secondary destination. Then, specify the slot, port, STS, DS1-14, and VT for the secondary destination.

---

Note The secondary destination is applied to open-ended UPSR and DRI.

---

Step 7 In the VLAN Selection pane (available only if an E-series Ethernet card or EtherGroup is chosen as the source or destination slot), complete the following substeps; then, click Next:

a. Select from the list of available VLANs to associate an existing VLAN to the circuit. If the Circuit VLANs list is empty, CTM assigns the default VLAN.

---

Note Gigabit Ethernet G-series, ML-series, and E-series cards that are configured in Port Mapped mode do not support VLAN assignment.

---

b. To create a new VLAN, click the New VLAN button. Enter a unique VLAN name and ID. The VLAN ID must be an integer greater than 1 but less than 4093. Click OK; then, click OK in the Successfully created VLAN confirmation dialog box. The new VLAN appears in the list of VLANs. The list is arranged alphanumerically by VLAN name, where numbers precede letters and uppercase letters precede lowercase ones.

c. Check the Enable Spanning Tree check box to enable spanning tree protection for the circuit. This option is disabled for intranode and multicard Ethernet circuits.

Step 8 In the Routing Preferences pane, complete the following substeps; then, click Next.

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. VT-DS3 Mapped Conversion—(Available only if Route Automatically is checked) If checked, you can route the circuit using the DS3XM12 card. Not applicable for data cards (ML-series and CE-100T-8 cards).

e. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable.

---

Note For VCAT circuits, you must enter multiple STS/VC4 values in the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter in the Time Slot Restriction field cannot be identical or circuit creation will fail with an error message.

---

f. Fully Protected Path—If not selected, choose Protection Channel Access to route the circuit on a BLSR protection channel.

g. Fully Protected Path—If selected, CTM ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking Dual Ring Interconnect. Alternately, if the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications:

•Required—CTM ensures that the primary and alternate paths within the UPSR portions of the complete circuit path are node-diverse.

•Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path.

•Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.

•Dual Ring Interconnect—If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

Step 9 In the VT Options pane (available only if you are creating a VT circuit and automatic routing is selected), choose one of the following radio buttons; then, click Next:

•Member Size—Select the size of the member for the VCAT circuit. This is the unit for VCAT circuit size.

•Number of Members—Select the number of members (of the size selected above). Different cards support different numbers of members with different sizes.

•Mode—Select the LCAS mode (None, Sw-LCAS, or LCAS) for the VCAT circuit. If other than None is selected as the Mode, only the cards supporting the LCAS mode selected will be listed for the source and destination selection.

•Protected Drops—Check this check box if you want the circuit routed to protected drops only; that is, to cards that are in 1:1, 1:N, or 1+1 protection.

•Provision working go and return on primary path (bidirectional UPSR/SNCP protection only)—Check this check box to provision the working path to go and return to the primary path.

•SNCP path selector defaults—If the circuit will be routed on an SNCP, set the defaults as follows:

–Revertive—Check this check box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If Revertive is not chosen, traffic remains on the protect path.

–Reversion time—If Revertive is checked, set the reversion time. This is the amount of time that will elapse before the traffic reverts to the working path. Traffic can revert when conditions causing the switch are cleared. (The Cisco default reversion time is 5 minutes.)

–SF threshold—Choose from 1 E-3, 1 E-4, or 1 E-5.

–SD threshold—Choose from 1 E-5, 1 E-6, 1 E-7, 1 E-8, or 1 E-9.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable.

---

Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.

---

e. Select the routing preference for VCAT members. If all members are to be routed on a single fiber, choose Common Fiber Routing. If members are to be routed through different fibers in case one fiber does not have sufficient bandwidth, choose Split Routing.

f. Specify the following member preferences:

•Number—Select the member number, a unique number from 1 to 256.

•Name—Edit the name for the member circuit. By default, <VCAT_NAME>_<Default MemberNumber> is the member name, where <VCAT_NAME> is the parent VCAT circuit name being created.

•Protection—Select the protection mechanism for member circuits. To route the circuit on a protected path, choose Fully Protected (default). A fully protected circuit route is created based on the diversity option you choose. Fully protected paths might or might not have UPSR/SNCP path segments with primary and alternate paths. The path diversity options apply only to UPSR/SNCP path segments, if any exist. To create an unprotected circuit, choose Unprotected.

•Node Diversity—Select node diversity for each member circuit.

g. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended UPSR/SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended UPSR/SNCP mesh network portion of the complete circuit path.

•Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended UPSR/SNCP mesh network portions of the complete circuit path are needed.

•N/A (Not Applicable)—Dual Ring Interconnect is not supported from CTM.

---

Note Node diversity can be set for each member when Fully Protected is selected and Split Fiber Routing is selected.

7.2.4.3  Creating a VC_HO_Path_Circuit

The E1-N-14 card, STM-N cards, and Ethernet cards all use high-order path circuits. You can create unidirectional or bidirectional, revertive or nonrevertive, high-order path circuits. CTM can route the circuits automatically, or you can route them manually. The E3-12 and DS3i-N-12 cards use VC low-order path tunnels.

---

Step 1 Select the node for which to create a circuit and open the Circuit wizard. For an explanation of Circuit wizard launch points, see Table 7-5.

Step 2 In the Type pane, choose VC_HO_Path_Circuit. The circuit type determines the provisioning options that are displayed. In the Number of Circuits field, enter the number of circuits you want to create. The Cisco default is 1. If you enter more than one, you can use autoranging to create the additional circuits automatically.

Step 3 Click Next.

Step 4 In the Attributes pane, enter the following information; then, click Next:

•Name—Enter a unique name for the new circuit. The circuit name is a free-format string of up to 48 ASCII characters.

•Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

•Description—Enter a circuit description of up to 256 characters.

•Size—Select the circuit size. VC high-order path circuits can be VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, VC4-16c, or VC4-64c for optical cards and for some Ethernet cards (depending on the card type). Of the Ethernet cards, only the G-1000 can use VC4-3c, VC4-8c, and VC4-16c. The "c" indicates concatenated VC4s.

•Bidirectional—Check this check box to create a two-way circuit; uncheck it to create a one-way circuit.

•State—Specify the circuit state. Options vary depending on the type of circuit selected.

•Apply to source/destination ports—Check this check box to apply the selected state to the source and destination ports.

•Protected Drops—Check this check box if you want the circuit routed to protected drops only; that is, to cards that are in 1:1, 1:N, or 1+1 protection.

•Provision working go and return on primary path (bidirectional UPSR/SNCP protection only)—Check this check box to provision the working path to go and return to the primary path.

---

Note CTM currently provisions unidirectional SNCP/UPSR circuits following the GR-1400 standard. For bidirectional SNCP/UPSR circuits, you can check the Provision working go and return on primary path check box to route the working and protect paths in one direction following the ITU-T G.841 standard. Unidirectional UPSR/SNCP circuits are not affected by this new routing, and the shortest path is always used as the working path.

---

•SNCP path selector defaults—If the circuit will be routed on an SNCP, set the defaults as follows:

–Revertive—Check this check box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If Revertive is not chosen, traffic remains on the protect path.

–Reversion time—If Revertive is checked, set the reversion time. This is the amount of time that will elapse before the traffic reverts to the working path. Traffic can revert when conditions causing the switch are cleared. (The Cisco default reversion time is 5 minutes.)

–SF threshold—Choose from 1 E-3, 1 E-4, or 1 E-5.

–SD threshold—Choose from 1 E-5, 1 E-6, 1 E-7, 1 E-8, or 1 E-9.

–Switch on PDI-P—Not applicable.

•Customer ID (optional)—Identify the end user of the circuit.

•Service ID (optional)—Enter the service ID of the circuit.

Step 5 In the Source pane, set the circuit source. The options displayed depend on the circuit type, the circuit properties selected in the Attributes pane, and the cards installed in the node. Click Use Secondary Source if you want to create an SNCP bridge/selector circuit entry point in a multivendor SNCP.

Step 6 Click Next.

Step 7 In the Destination pane, set the circuit destination. The options displayed depend on the circuit type, the circuit properties selected in the Attributes pane, and the cards installed in the node. Click Use Secondary Destination if you want to create a circuit destination point for unidirectional/bidirectional circuits.

Step 8 Click Next.

Step 9 In the Routing Preferences pane, complete the following substeps; then, click Next:

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable.

---

Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.

---

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 10.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 10.

In the Number of Circuits field, enter the number of circuits you want to create. The Cisco default is 1. If you enter more than one, you can use autoranging to create the additional circuits automatically.

Step 3 Click Next.

Step 4 In the Attributes pane, enter the following information; then, click Next:

•Name—Enter a unique name for the new circuit. The circuit name is a free-format string of up to 48 ASCII characters.

•Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

•Description—Enter a circuit description of up to 256 characters.

•Size—For VC_LO_Path_Aggregation, this is automatically set to VC4.

•Bidirectional—For VC_LO_Path_Aggregation, this is automatically set to bidirectional.

•State—Specify the circuit state. Options vary depending on the type of circuit selected.

•Apply to source/destination ports—Check this check box to apply the selected state to the source and destination ports.

•Protected Drops—Check this check box if you want the circuit routed to protected drops only; that is, to cards that are in 1:1, 1:N, or 1+1 protection.

•SNCP path selector defaults—If the circuit will be routed on an SNCP, set the defaults as follows:

–Revertive—Check this check box if you want traffic to revert to the working path when the conditions that diverted it to the protect path are repaired. If Revertive is not chosen, traffic remains on the protect path.

–Reversion time—If Revertive is checked, set the reversion time. This is the amount of time that will elapse before the traffic reverts to the working path. Traffic can revert when conditions causing the switch are cleared. (The Cisco reversion time is 5 minutes.)

–SF threshold—Choose from 1 E-3, 1 E-4, or 1 E-5.

–SD threshold—Choose from 1 E-5, 1 E-6, 1 E-7, 1 E-8, or 1 E-9.

If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable.

---

Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.

7.2.4.8  Creating a DWDM OCHCC

CTM allows you to create OCHCC circuits between two CRS-1 or ONS 15454 MSTP products. ONS 15454 MSTP is a DWDM optical product designed to provide transparent, reliable, and manageable transport capacity to Cisco Metro optical products such as ONS 15454 MSPP, ONS 15530, and ONS 15540. OCHCC increases ONS 15454 MSTP platform functionalities, providing the possibility to create a new E2E circuit layer with transponder/muxponder client ports or ITU-T line card trunk ports as endpoints.

OCHCC can be created in a peer-to-peer setup, where the trunk ports are directly connected by a routable virtual link, or in an MSTP setup, where the circuit is routed through a tunnel circuit, which is created between the trunk ports (OCH trail tunnel), and which in practice contains an OCHNC-type circuit.

OCHCC circuit creation is supported on CRS-1 NEs with the ITU Physical Layer Interface Modules (PLIMs) on 10 GE C-band and OC768 interfaces. OCHCC circuit creation between CRS-1 NEs is supported in the following scenarios:

•Trunk ports of CRS-1 peers pass through an ONS 15454 MSTP and the PLIM TXP card is connected to the ONS 15454 MSTP through two manually routable unidirectional physical links at 10G-ITU layer rate. One unidirectional link is from the CRS-1 trunk port to the ONS 15454 MSTP DEMUX card port; the other unidirectional link is from the ONS 15454 MSTP MUX card port to the same trunk port on the CRS-1.

If there is more than one ONS 15454 MSTP NE connection between CRS-1 peers, an OCHNC circuit is created automatically between the ONS 15454 MTSP NEs. The following figure shows a graphical representation of this scenario.

Figure 7-2 CRS-1 DWDM OCHCC Circuit Creation—Scenario 1

•Trunk ports of CRS-1 peers do not pass through an ONS 15454 MSTP and the PLIM cards are directly connected to the trunk ports of the CRS-1 NEs. The following figure shows a graphical representation of this scenario.

Figure 7-3 CRS-1 DWDM OCHCC Circuit Creation—Scenario 2

Note Autodiscovery is not supported on OCHCC circuits on CRS-1 NEs.

---

---

Step 1 Select the node for which to create a circuit and open the Circuit wizard. For an explanation of Circuit wizard launch points, see Table 7-5.

Step 2 In the Type pane, choose OCHCC. The circuit type determines the provisioning options that are displayed.

Step 3 Click Next.

Step 4 In the Attributes pane, enter the following information; then, click Next:

•Name—Enter a unique name for the new circuit. The circuit name is a free-format string of up to 48 ASCII characters.

•Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

•Description—Enter a circuit description of up to 256 characters.

•Type—Choose a client payload from the list displayed. For CRS-1, this is a read-only field.

•Size Group—Choose the type of interface you want to provision. Size Group and Size are used together to select the circuit size. (Because there are many possible sizes, they have been grouped.)

•Size—Choose the layer rate.

•OCHCC Wavelength—Choose the OCHCC wavelength you want to provision.

•Channel Group—Choose the channel group you want to provision. In CTM R7.2, only the C-band channel group is supported for CRS-1 circuits.

•Bidirectional (read-only)—OCHCC circuits are always bidirectional.

•State—Specify the circuit state.

•Apply to source/destination ports, if allowed—Check this check box to apply the status value indicated for the circuit to the client/trunk ports involved in the circuit. This field is not available for CRS-1 circuits.

•Protected—Check this check box to allow you to select source/destination ports only from protected cards (TXPP/MXPP).

•Trunk—Check this check box to allow you to select source/destination ports only from cards that allow trunk port settings. The trunk attributes allow you to filter the list of cards to display compatible cards only, and also allow you to set the attributes of the trunk ports that are included in the circuit. For MXP cards, trunk attributes are used to set the trunk port when the first circuit is created using that trunk port; then they are used to filter trunk ports. Values of all the attributes must match current trunk status, to allow you to create another circuit using the same card. This field is not available for CRS-1 circuits.

•G.709 OTN—Disables or enables the G.709 OTN feature. Check this check box to filter the list of circuits to display only G.709 OTN-compatible circuits.

•FEC—Disables or enables forward error correction. G.709 OTN must be enabled before you can enable FEC.

•SF BER (read-only)—Displays the signal fail bit error rate.

•SD BER—Sets the signal degrade bit error rate.

•Mapping—The card can perform multiplexing per ITU-T G.709. The ODUk (client SONET/SDH payload) can be mapped to the optical channel (OTUk) either asynchronously (asynch mapping) or synchronously (synch mapping) with this setting.

•Customer ID (optional)—Identify the end user of the circuit.

•Service ID (optional)—Enter the service ID of the circuit.

Step 5 In the Source pane, select the circuit source (Shelf/Slot/Card/Port; Shelf only in the case of NEs configured as multishelf); then, click Next.

Step 6 In the Destination pane, enter the circuit destination information (Shelf/Slot/Card/Port; Shelf only in the case of NEs configured as multishelf); then, click Next.

---

Note Circuit creation will fail if the source or destination endpoints are in Unmanaged state. Circuit creation is not allowed between NEs in Out of Service or Unmanaged states.

---

Step 7 Click Finish.

---

Caution It takes several seconds to create a circuit. During that interval, if a new circuit is added with the same name, both circuits might be identified as duplicates. Therefore, be careful not to add a duplicate circuit during the creation of the first circuit.

---

7.2.4.9  Creating a Monitor Circuit—CTC-Based NEs

Use the Create Monitor Circuit wizard to create a new monitor circuit on CTC-based NEs.

---

Note A monitor circuit's alias is based on the alias of the original circuit. CTM does not generate unique numbers; therefore, two monitor circuits created on the same circuit will have the same alias, while their names will be different (including two unique numbers appended in the network).

---

---

Step 1 Select the CTC-based NE where you want to create a monitor circuit and open the Circuit table. For an explanation of Circuit table launch points, see Table 7-2.

Step 2 In the Circuit table, select the bidirectional circuit to be monitored.

Step 3 Choose Configuration > Modify Circuit (or click the Modify tool). The Modify Circuit dialog box opens.

Step 4 In the Modify Circuit dialog box, click the Monitor tab. The Monitor tab displays the ports that can be used to monitor the circuit selected in Step 2.

Step 5 In the Monitor tab, select the monitor source and click Create Monitors. The Create Monitor Circuit wizard opens.

Step 6 In the Create Monitor Circuit wizard, enter the following monitor circuit information; then, click Next:

•Name—Enter the monitor circuit name.

•Circuit Alias—Enter a unique alias name for the new circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

•State—Specify the circuit state. Options vary depending on the type of circuit selected.

Step 7 In the Source pane, choose the source node, slot, port, STS, VT, or DS-1 for the monitored circuit; then, click Next.

Step 8 In the Destination pane, choose the destination node, slot, port, STS, VT, or DS-1 for the monitored circuit; then, click Next.

Step 9 In the Routing Preferences pane, complete the following substeps; then, click Next:

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable.

---

Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.

---

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 10.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 10.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended SNCP mesh network portion of the complete circuit path.

•Don't Care: Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended SNCP mesh network portions of the complete circuit path are needed.

7.2.4.11  Creating G1000-4 Circuits

This section explains how to provision G1000-4 point-to-point circuits and Ethernet manual cross-connects. Ethernet manual cross-connects allow you to cross-connect individual Ethernet circuits to an STS channel on the ONS 15454 SONET or ONS 15454 SDH optical interface and to bridge non-ONS SONET network segments.

7.2.4.11.1  G1000-4 Point-to-Point Ethernet Circuits

G1000-4 cards support point-to-point circuit configuration. Provisionable circuit sizes are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c. Each Ethernet port maps to a unique STS circuit on the SONET side of the G1000-4.

The G1000-4 card supports any combination of up to four circuits from the list of valid circuit sizes; however, the circuit sizes can add up to no more than 48 STSs. Due to hardware constraints, the initial release of the G1000-4 card (software release 3.2) imposes additional restrictions on the combinations of circuits that can be dropped onto a G1000-4 card. These restrictions are transparently enforced by the ONS 15454 SONET and ONS 15454 SDH, so there is no need to keep track of restricted circuit combinations.

•The restriction occurs when a single STS-24c is dropped on a card. In this instance, the remaining circuits on that card can be another single STS-24c or any combination of circuits of STS-12c size or smaller that add up to no more than 12 STSs (that is, a total of 36 STSs on the card).

•No circuit restrictions are present if STS-24c circuits are not being dropped on the card. The full 48 STSs of bandwidth can be used (for example, a single STS-48c circuit or 4 STS-12c circuits).

•Since the restrictions apply only when STS-24c circuits are involved but do not apply when two STS-24c circuits are on the same card, the impact of these restrictions can be easily minimized. Group the STS-24c circuits together on a card separate from circuits of other sizes. The grouped circuits can be dropped onto other G1000-4 cards on the ONS 15454 SONET or ONS 15454 SDH. The G1000-4 uses STS cross-connects only. No VT-level cross-connects are used. All SONET-side STS circuits must be contiguous.

---

Caution G1000-4 circuits connect with OC-N cards or other G1000-4 cards. G1000-4 cards do not connect with E-series Ethernet cards.

---

---

Caution The G1000-4 card requires the XC10G card to operate. The G1000-4 card is not compatible with XC or XCVT cards.

---

---

Step 1 In the Domain Explorer, select the ONS 15454 SONET or ONS 15454 SDH NE that will be used as one of the Ethernet circuit endpoints.

Step 2 Complete the following in the Domain Explorer:

a. Select the source circuit.

b. Choose Configuration > Create Circuit.

c. Select the destination circuit. The Create Circuit wizard opens.

Step 3 From the Type field, choose STS; then, click Next. The Attributes pane opens.

---

Note The VT and VT Tunnel types do not apply to Ethernet circuits.

---

Step 4 In the Name field, enter a name for the circuit.

Step 5 In the Circuit Alias field, enter a unique alias name for the circuit. The alias name can contain alphanumeric characters. It also supports international character sets.

Step 6 From the Size field, choose the size of the circuit. The valid circuit sizes for a G1000-4 circuit are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, and STS-48c.

Step 7 Verify that the Bidirectional check box is checked.

---

Note The states of the Number of Circuits check box and the Protected Drops check box are provided.

---

---

Caution If provisioning a G1000-4 circuit on a UPSR, do not check the Switch on PDI-P check box. Checking the Switch on PDI-P check box might cause unnecessary UPSR protection switches.

---

Step 8 (Optional) Specify the customer information:

•Customer ID

•Service ID

Step 9 Click Next.

Step 10 In the Source pane, choose the circuit source node. Either end node can be the circuit source.

Step 11 From the Slot field, choose the slot containing the G1000-4 card that will be used for one end of the point-to-point circuit.

Step 12 In the Port field, choose a port.

Step 13 Click Next.

Step 14 In the Destination pane, choose the circuit destination node.

Step 15 In the Slot field, choose the slot that holds the G1000-4 card that will be used for the other end of the point-to-point circuit.

Step 16 From the Port field, choose a port.

Step 17 Click Next. The Routing Preferences pane opens.

Step 18 In the Routing Preferences pane, complete the following substeps; then, click Next:

a. Route Automatically—Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. If the source and destination of the circuit are on the same node, automatic routing is enabled. If disabled, you can specify the spans associated with the circuit. You can manually provision the circuit using one of the following views:

•Graphical

•Textual

b. Using Required Nodes/Links—(Available only if Route Automatically is checked) Check this check box to let CTM automatically route the circuit through the required nodes and/or links. You can specify the required nodes and links using one of the following views:

•Graphical

•Textual

c. Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable.

---

Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.

---

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 19.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 19.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended SNCP mesh network portion of the complete circuit path.

•Don't Care: Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended SNCP mesh network portions of the complete circuit path are needed.

•Dual Ring Interconnect—Provisions the circuit in a DRI topology. If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

7.2.4.11.2  G1000-4 Manual Cross-Connects

ONS 15454 SONET and ONS 15454 SDH NEs require end-to-end CTC visibility between nodes for normal provisioning of Ethernet circuits. When equipment from other vendors is placed between the ONS 15454 SONET and ONS 15454 SDH, equipment based on Open System Interconnection/Target Identifier Address Resolution Protocol (OSI/TARP) does not allow tunneling of the ONS 15454 SONET or ONS 15454 SDH TCP/IP-based data communications channel (DCC). To circumvent a lack of continuous DCC, the Ethernet circuit must be manually cross-connected to an STS channel riding through the non-ONS network. This allows an Ethernet circuit to run from ONS node to ONS node while utilizing the non-ONS network.

---

Note In this chapter, cross-connect and circuit have the following meanings: Cross-connect refers to the connections that occur within a single ONS 15454 SONET or ONS 15454 SDH to allow a circuit to enter and exit an ONS 15454 SONET or ONS 15454 SDH. Circuit refers to the series of connections from a traffic source (where traffic enters the ONS 15454 SONET or ONS 15454 SDH network) to the drop or destination (where traffic exits an ONS 15454 SONET or ONS 15454 SDH network).

7.2.4.12  Creating E-Series Circuits

Ethernet circuits can link ONS nodes through point-to-point, shared packet ring, or hub-and-spoke configurations. Two nodes usually connect with a point-to-point configuration. More than two nodes usually connect with a shared packet ring configuration or a hub-and-spoke configuration. This section includes procedures for creating these configurations and also explains how to create Ethernet manual cross-connects. Ethernet manual cross-connects allow you to cross-connect individual Ethernet circuits to an STS channel on the ONS 15454 SONET or ONS 15454 SDH optical interface and also to bridge non-ONS SONET network segments.

---

Note Before creating Ethernet connections, choose an STS-1, STS-3c, STS-6c, or STS-12c circuit size.

---

---

Note When creating an STS-12c Ethernet circuit, Ethernet cards must be configured as single-card EtherSwitch. Multicard mode does not support STS-12c Ethernet circuits.

---

7.2.4.12.4  E-Series Ethernet Manual Cross-Connects

ONS 15327, ONS 15454 SONET, and ONS 15454 SDH NEs require end-to-end CTC visibility between nodes for normal provisioning of Ethernet circuits. When equipment from other vendors is positioned between ONS 15327, ONS 15454 SONET, or ONS 15454 SDH NEs, equipment based on OSI/TARP does not allow tunneling of the ONS 15327, ONS 15454 SONET, or ONS 15454 SDH TCP/IP-based DCC. To circumvent this lack of continuous DCC, the Ethernet circuit must be manually cross-connected to an STS channel riding through the non-ONS network. This allows an Ethernet circuit to run from ONS node to ONS node by utilizing the non-ONS network.

---

Note Provisioning manual cross-connects for multicard EtherSwitch circuits is a separate procedure from provisioning manual cross-connects for single-card EtherSwitch circuits. Both procedures are provided in the following sections.

---

---

Step 1 In the Domain Explorer tree, select the CTC-based NE and choose Configuration > CTC-Based SONET NEs or CTC-Based SDH NEs > Circuit Table.

Step 2 In the Circuit table, select a circuit; this circuit will be the master circuit.

Step 3 Choose Configuration > Merge Table. The fields in the Circuit Merge table are identical to the fields in the Circuit table (Table 7-3). The Circuit Merge table displays the circuits that are path aligned with the master circuit. These circuits are called slave circuits. The Circuit Merge table shows circuits (slave circuits) that are the same size as the master circuit.

---

Note You must merge n selected slave circuits with one selected master circuit. When circuits are merged from CTM, EMS attributes such as customer ID, service ID, description, and comments are retained only for master circuits. If the circuit merge is done through CTC, the EMS attributes are not retained in CTM.

---

---

Note Circuits are allowed to merge only if the following conditions exist:
— Their connections are path aligned.
— They have compatible circuit type, size, and direction.
— They do not have different VLAN assignments.
— They do not have different nondefault SLA values.
— They have compatible circuit endpoints.
— They do not form an invalid circuit.

---

Step 4 To refresh any new aligned circuits with the selected circuit, choose Configuration > Refresh Lined Up Circuits (or click the Refresh Lined Up Circuits tool).

Step 5 Specify the circuit(s) that you want to merge with the selected circuit and choose Configuration > Merge (or click the Merge tool).

Step 6 If the selected circuit(s) cannot be merged completely into the current circuit, the following message appears:

The selected circuit(s) cannot be merged completely into the current circuit. Disjointed 
remnants of the selected circuit(s) might remain after the merge. Click OK to continue.

Step 7 Click OK to continue with the merge, or click Cancel to cancel the operation.

---

Note The EMS attributes of the circuits are lost after the circuit reconfigure.

---

Step 8 To reconfigure circuits, return to the Circuit table, select the circuit(s) to reconfigure, and choose Configuration > Reconfigure Circuit(s). A progress bar displays the status of the reconfiguration. A failed or succeeded message displays the results of the reconfiguration.

7.2.11  Repairing a Circuit

The Alarm Interface Panel (AIP) provides surge protection for CTC-based NEs. This pane has a nonvolatile memory chip that stores the unique node address known as the MAC address. The MAC address identifies the nodes that support circuits. It allows CTM to determine circuit sources, destinations, and spans. If an AIP fails, an alarm will be generated and the LCD display on the fan tray assemblies of the NEs will go blank. To perform an in-service replacement of the AIP, you must contact the Cisco Technical Assistance Center (TAC). For contact information, visit the TAC website at http://www.cisco.com/tac.

You can replace the AIP on an in-service system without affecting traffic by using the circuit repair feature. If the AIP card needs to be replaced, you will need to repair circuits affected by the MAC address change on the NE. Circuit repair will work when all nodes are running the same software version. Each individual AIP replacement requires an individual circuit repair; if AIPs are replaced on two NEs, the circuit repair must be performed twice. Repairing circuits allows you to change the MAC address of all circuits originating at an NE to a user-provided NE ID. To repair a CTM circuit when an AIP card is changed, restart the CTM server or complete the following steps:

---

Note While completing the following steps, do not create or delete any circuits using CTM.

---

---

Note The following procedure applies to circuits on CTC-based NEs.

---

---

Step 1 Refer to Cisco ONS 15454 Reference Manual to replace the AIP card.

---

Note Reset both Timing Communications and Control (TCC) cards after the AIP card is replaced.

---

Step 2 In the Domain Explorer, choose Administration > Control Panel.

Step 3 Expand Network Service.

Step 4 Select CTC-Based SONET or CTC-Based SDH and deactivate the network service. Click Save.

Step 5 Activate the network service again and click Save.

Step 6 In the Domain Explorer, select the CTC-based NE and choose Configuration > CTC-Based SONET NEs or CTC-Based SDH NEs > Repair Circuit. The Repair Circuit dialog box opens.

The Repair Circuit dialog box allows you to change the MAC address of all circuits originating at the selected NE with a user-provided NE ID. MAC addresses are a subset of data link layer addresses. MAC addresses identify network entities in LANs implementing the IEEE MAC sublayer of the data link layer. The following table provides descriptions.

Step 7 After making your selections, click OK.

---

Table 7-11 Field Descriptions for the Repair Circuit Dialog Box 

Field	Description
Old MAC Address	Enter the current MAC address of the NE. MAC addresses are 48 bits in length and are expressed as 12 hexadecimal digits (0-9, a-f): •The first 6 hexadecimal digits are the manufacturer identification (or vendor code), called the Organizational Unique Identifier (OUI). These 6 digits are administered by the IEEE. •The last 6 hexadecimal digits are the interface serial number or another value administered by the specific vendor.
New MAC Address	Enter the new MAC address of the NE.

7.2.21.2  Viewing a J1 Path Trace from the NE Explorer

The SONET J1 path trace is a repeated, fixed-length string comprised of 64 consecutive J1 bytes. You can use the string to monitor interruptions or changes to circuit traffic. The Cisco ONS 15454 Reference Manual available at http://www.cisco.com/univercd/cc/td/doc/product/ong/15400/index.htm shows the ONS 15454 cards that support path trace. DS-1 and DS-3 cards can transmit and receive the J1 field, while the EC-1, OC-3, OC-48AS, and OC-192 can only receive J1 bytes. Cards that are not listed in the reference manual do not support J1 bytes.

7.2.24.1  Viewing the Rolls Table

The Rolls table displays circuit roll information for the selected NE or NEs. The rolling maintenance function is available in CTC-based NEs to move live traffic from one entity to another. The connections can be single- or dual-ended. Only path-level (not line-level) bridging and rolling is supported.

To view the Rolls table, select a CTC-based NE in the Domain Explorer tree and choose Configuration > CTC-Based SONET NEs or CTC-Based SDH NEs > Rolls Table. The following table provides descriptions.

Table 7-25 Field Descriptions for the Rolls Table 

Field	Description
Roll from Circuit	Displays the name of the circuit where the circuit roll originates.
Roll to Circuit	Displays the name of the circuit where the circuit roll terminates. This value could be the same as Roll From Circuit when only a single circuit is involved in a roll.
Roll State	Displays the current state of the circuit roll. Values are: •ROLL_PENDING—The roll is awaiting completion or cancellation. •ROLL_COMPLETED—The roll has already been completed. •ROLL_CANCELLED—The roll has been cancelled.
Roll Valid Signal	Displays the roll valid signal status (True or False).
Roll Mode	Displays the roll mode. Values are: •Automatic—When a valid signal is received on the new path, CTM completes the roll on the node automatically. You can cancel an automatic roll only when the Roll Valid Signal value is False. One-way source rolls are always automatic. •Manual—You must complete a manual roll after a valid signal is received. You can cancel a manual roll at any time. One-way destination rolls are always manual.
Roll Path	Displays the roll path for the entire circuit roll.
Roll from Path	Indicates the path that is being rolled away. The original cross-connection goes from Roll Path to Roll from Path.
Roll to Path	Indicates the new path being rolled to. After a successful completion of a roll, the new cross-connection goes from Roll Path to Roll to Path.

7.2.24.2  Rolling a Circuit

Use the Roll Circuit wizard to transfer CTC-based NE traffic from one facility to another without service interruption. The wizard is generally used to move a circuit off a card (for card or facility replacements) or to increase bandwidth utilization (for example, by moving lower-rate circuits across a shared high-rate circuit or rerouting circuits or parts of a circuit).

Routing Preferences View (available when Circuit Roll Mode is Dual)
Route Automatically	Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. Alternately, you can choose manual routing and specify all the intermediate hops on a hop-by-hop basis (up to 64 hops per circuit). Note If the source and destination of the circuit are on the same node, automatic routing is enabled.
Using Required Nodes/Links	(Available only if Route Automatically is checked) If checked, CTM automatically routes the circuit through the required nodes and/or links.
Review Route Before Creation	(Available only if Route Automatically is checked) Check this check box to review the route before it is created.
VT-DS3 Mapped Conversion	(Read-only) If checked, the roll-away path includes the node on which the VT/DS-3 conversion is done. If unchecked, the roll-away path does not include the node on which the VT/DS-3 conversion is done.
Time Slot Restriction	If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable. Note Time Slot Restriction is not available for OCHCC and OCHNC circuit types. Note For VCAT circuits, you must enter multiple STS/VC4 values in the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter in the Time Slot Restriction field cannot be identical or circuit creation will fail with an error message.
Fully Protected Path	If selected, CTM ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking the Dual Ring Interconnect check box. Alternately, if the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications: •Required—Ensures that the primary and alternate paths of the UPSR portions of the complete circuit path are node-diverse. •Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. •Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.
Protection Channel Access	To route the circuit on a BLSR protection channel, if available, uncheck the Fully Protected Path check box, and check the Protection Channel Access check box.
Dual Ring Interconnect	If you selected Fully Protected Path and the circuit will be routed on a DRI, check the Dual Ring Interconnect check box. Note For DRI and iDRI manually created circuits, you must double-click the DRI span for it to become DRI. A single-click does not enable the DRI span.
Diverse Shared Risk Link Group (SRLG)	If checked, fully protected circuits will be routed through working and protected links that do not share risk groups.
Manual Provisioning
Map view	Displays the NEs that are available in the subnetwork for circuit creation. This pane also indicates the source (and secondary source, if applicable) and destination (and secondary destination, if applicable) NEs selected for circuit creation. The map view is used to manually route the circuit from the source to the destination specified by the addition of the links selected. Use the right-click menu options to navigate within the map view: •Find Node—Opens the Find Node dialog box, which lists all of the nodes displayed on the map view. Select a node from the drop-down list and click OK. The selection context in the map view changes to show the selected node highlighted in the visible map area. •Zoom In—Allows you to zoom in on an object in the map view. •Zoom Out—Allows you to zoom out on the map view. •Reset Zoom—Resets the current zoom level to the default.
Available Spans	Select a link on the map view (related to the selected node) and its corresponding details are displayed in the Available Spans pane. Click Add to move the spans to the Selected Spans field. The newly added link appears in blue on the map view.
Selected Spans	Select one or more spans and click Remove to remove them from the Selected Spans field. The removed link appears in green to indicate its unselected state. Note To specify a DRI link, double-click the link on the map. The map view displays the link as bidirectional.
Links/Nodes tab	Select the links/nodes in the graphic to populate the selected node field.
BLSR DRI Nodes or MS-SPRing DRI Nodes tab	(For BLSR DRI or MS-SPRing DRI circuits) Click the Add button to open the BLSR/MS-SPRing DRI dialog box, which allows you to provide primary and secondary pairs for traditional and nontraditional DRI circuits. Also specify ring and path options for the first and second rings. Click Remove to remove a DRI node from the list.
Route Constraints (available only if the Using Required Node/Links check box is checked)
Map view	Displays the NEs that are available in the subnetwork for circuit creation. This pane also indicates the source (and secondary source, if applicable) and destination (and secondary destination, if applicable) NEs selected for circuit creation. The map view is used for the inclusion and exclusion of links or nodes during the specification of route constraints. The included nodes are shown in blue and the excluded links are shown in magenta. Use the right-click menu options to navigate within the map view: •Find Node—Opens the Find Node dialog box, which lists all of the nodes displayed on the map view. Select a node from the drop-down list and click OK.

Included Links/Nodes	Displays the list of links or nodes that are included in the route.
Excluded Links/Nodes	Displays the list of links or nodes that are excluded from the route.
VT/VC LO Circuit Options (available only for VT and VC LO path circuits)
VT/VC LO Tunnel on Transit Nodes	This option is available if the VT or VC circuit passes through a node that does not have a low-order tunnel, or if an existing low-order tunnel is full. Low-order tunnels allow VT/VC circuits to pass through NEs without consuming low-order cross-connect card resources. In general, creating tunnels is a good idea if you are creating many low-order circuits from the same source and destination.
VT Aggregation Point (VAP)/VC LO Aggregation Point (LAP)	(For SONET) This option is available if you are creating a VT1.5 circuit on a DS-1, EC-1, DS3XM-6; or an OC-N port on a BLSR, 1+1, or unprotected node. A VAP allows VT1.5 circuits to be routed through a node using one STS connection on the cross-connect card matrix rather than multiple connections on the VT1.5 matrix. (For SDH) This option is available if you are creating a VC12 circuit on an STM-N port for handoff to non-SDH networks or equipment, such as an IOF, switch, or DACS. A LAP allows low-order circuits to be routed through a node using one VC4 connection on the cross-connect card high-order matrix rather than multiple connections on the low-order matrix.
First fixed point is STS/VC4 Grooming Node	Creates the VAP or LAP on the VT or VC circuit source node. This option is available only if the VT circuit originates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit originates on an STM-N card.
Second fixed point is STS/VC4 Grooming Node	Creates the VAP or LAP on the VT or VC circuit destination node. This option is available only if the VT circuit terminates on a DS-1, EC-1, DS3XM-6, or OC-N card, or if the VC circuit terminates on an STM-N card.
None	Choose this option if you do not want to create a low-order tunnel or a VAP/LAP. This is the only available option if CTM cannot create a low-order tunnel or VAP/LAP.
Conversion Route Constraints (available only if VT-DS3 Mapped Conversion is checked)
NE ID	Select from the list of available NE IDs to specify the source NE ID.
Subnetwork ID	(Read-only) Displays the ID of the subnetwork associated with the circuit source.
Slot	Specify the source slot that contains the DS3XM card.
DS3 Mapped STS	Choose Circuit Source or Circuit Dest.

This pane also indicates the source (and secondary source, if applicable) and destination (and secondary destination, if applicable) NEs selected for circuit creation. The map view is used for the inclusion and exclusion of links or nodes during the specification of route constraints. The included nodes are shown in blue and the excluded links are shown in magenta. Use the right-click menu options to navigate within the map view: •Find Node—Opens the Find Node dialog box, which lists all of the nodes displayed on the map view. Select a node from the drop-down list and click OK. The selection context in the map view changes to show the selected node highlighted in the visible map area. •Zoom In—Allows you to zoom in on an object in the map view. •Zoom Out—Allows you to zoom out on the map view. •Reset Zoom—Resets the current zoom level to the default.
Review Route	Displays the NEs that are available in the subnetwork for circuit creation. This pane also indicates the source (and secondary source, if applicable) and destination (and secondary destination, if applicable) NEs selected for circuit creation. The map view displays information about the spans selected during autorouting in the subnetwork. The selected spans are shown in blue. When you select a span, its corresponding details are displayed in the Selected Span pane. The circuit summary displays the total hops and the cost for working and protect paths for the routed circuit.
Source NE ID	Displays the ID of the NE selected as the source node.
Destination NE ID	Displays the ID of the NE selected as the destination node.
Included Spans	If you enabled automatic route selection in the Routing Preferences pane, CTM automatically selects spans to route the circuit. This field lists all the spans that the CTM server selected automatically.
Selected Span	Displays detailed information about the span selected in the Included Spans list.

Step 3 In the Roll section of the Roll Attributes pane, specify the following information:

•Circuit Roll Mode—Select either:

–Auto—Create an automatic roll (required for a one-way source roll).

7.3.2.2  Creating a BLSR from the NE Explorer

---

Step 1 Select a CTC-based SONET NE in the Domain Explorer and choose Configuration > NE Explorer (or click the Open NE Explorer tool).

Step 2 Click the BLSR tab.

Step 3 Click Create.

Step 4 In the Create BLSR dialog box, set the BLSR properties:

•Fiber Type—Select the BLSR fiber ring type (2-fiber or 4-fiber).

•Ring Name—Assign the BLSR ring name.

•Ring ID—Assign a ring ID (a number from 0 to 9999). Nodes in the same BLSR must have the same ring ID.

•Node ID—Assign a node ID. The node ID identifies the node to the BLSR. Nodes in the same BLSR must have unique node IDs.

•Ring Reversion—Set the amount of time that will pass before the traffic reverts to the original working path. The Cisco default is 5.0. All nodes in a BLSR ring should have the same ring reversion setting, particularly if Never (that is, nonrevertive) is selected.

•West Line—Assign the west BLSR port for the node from the drop-down list.

•East Line—Assign the east BLSR port for the node from the drop-down list.

For 4-fiber BLSRs, complete the following information:

•Span Reversion—Set the amount of time that will pass before the traffic reverts to the original working path following a span reversion. The Cisco default is 5 minutes. Span reversions can be set to Never. If a ring reversion time was set, the times must be the same for both ends of the span. That is, if the west fiber of Node A is connected to the east port of Node B, the Node A west span reversion time must be the same as the Node B east span reversion time. To avoid reversion time mismatches, it is recommended that you use the same span reversion time throughout the ring.

•West Protect—Assign the west BLSR port that will connect to the west protect fiber.

•East Protect—Assign the east BLSR port that will connect to the east protect fiber.

Step 5 Click OK.

---

Note Some or all of the following alarms appear during BLSR setup: E-W MISMATCH, RING MISMATCH, APSCIMP, APSDFLTK, BLSROSYNC. The alarms will clear after all of the nodes in the BLSR are configured.

Step 6 Complete Steps 1 through 5 at each node where the BLSR will be added.

Step 7 After configuring the last BLSR node, wait for the BLSR Ring Map Change dialog box to appear. This can take from 10 to 30 seconds.

---

Note The dialog box does not appear if SDCC Termination alarms (such as EOC) or BLSR alarms (such as E-W MISMATCH and RING MISMATCH) are present. If an SDCC alarm is present, review the DCC provisioning at each node. If BLSR alarms have not cleared, repeat Steps 1 through 5 at each node, making sure that each node is provisioned correctly. The dialog box does not apply to the ONS 15327 R3.4 or ONS 15454 R3.4.

---

Step 8 In the BLSR Ring Map Change dialog box, click Yes.

Step 9 In the BLSR Ring Map Change dialog box, verify that the ring map contains all of the provisioned nodes in the expected order. If so, click Accept. If the nodes do not appear, or are not in the expected order, repeat Steps 1 through 8, making sure that no errors are made.

Step 10 Test the BLSR using the following standard site testing procedure:

a. Run test traffic through the ring.

b. Click the BLSR tab and then click BLSR Span. Choose MANUAL RING from the East Switch list. Click Apply.

c. In the Alarm Browser, verify that a Ring Switch West event is displayed, and that the far-end node that responded to this request reports a Ring Switch East event.

d. Verify that traffic switches normally.

e. Choose Clear from the East Switch list and click Apply.

f. Repeat Steps a through d for the west switch.

g. Disconnect the fibers at one node and verify that traffic switches normally.

7.5  Managing VLANs for E-Series Cards

VLANs are managed at the network partition level. All VLANs that are discovered on one NE are propagated to all available NEs under the same network partition. Creating, editing, or deleting VLANs affects all the NEs under the network partition.

---

Caution Make sure that the VLANs are unique across the entire network partition.

---

If you use CTC to manage VLANs, CTM will discover two VLANs with the same name but different IDs if the following conditions exist:

•You created a VLAN with an ID and name in one ring

•You created another VLAN with the same name but a different ID in another ring managed by another instance of CTC

•Both rings are managed by the same network partition in CTM

A similar situation arises when two or more VLANs are created with the same ID but different names.

---

Note The procedures in this section apply only to E-series cards. VLAN association for E-series cards is done during circuit creation.

---

The following table describes the various tasks that can be performed from the Manage VLANs dialog box.

Table 7-46 VLAN Management Tasks 

Task	Description	See
Create a VLAN	Use the Manage VLANs dialog box to create new VLANs.	Creating a VLAN

---

Step 3 You are prompted to confirm the deletion request. Click OK.

Step 4 In the confirmation dialog box, click OK.

---

7.6  Managing VLANs (ML-Series Cards)

A VLAN is an end-to-end service within a Layer 2 topology. When provisioning a VLAN, CTM internally configures bridge groups, one on each card, wherever an Ethernet service drop is specified. A bridge group associates a service drop with the service VLAN ID, the optical virtual port subinterface. A VLAN service is a collection of bridge groups on a particular Layer 2 topology.

Bridge groups are invisible on the Layer 2 service provisioning application. You can review the associated service drops on each VLAN service.

---

Step 1 Select an existing Layer 2 topology from the Layer 2 Topology table.

Step 2 Select a service provider VLAN ID.

Step 3 Specify a customer ID and service ID. These are strings that you can assign to a VLAN service during provisioning. This information is local to CTM and is not configurable on the NE.

Step 4 Specify the QoS parameters (CIR/PIR).

Step 5 Specify the service drops. There must be at least one drop per ML card for point-to-point and Layer 2 topologies, and at least two drops, on a different card, for Resilient Packet Ring (RPR).

Step 6 For each drop port, specify the port type and connection type.

---

7.7  Provisioning Data Services

---

Note Layer 2 (L2) services apply to ONS 15310 CL, ONS 15310 MA, ONS 15454 SONET, and ONS 15454 SDH NEs only.

---

---

Note You need to complete all prerequisites for adding NEs before provisioning data services. See section 3.5.1  Prerequisites for Adding NEs, page 3-8 for information.

---

Metro Ethernet service capability is available through the ML-series cards on the ONS 15454 NE and the ML-100T-8 card on the ONS 15310 CL and ONS 15310 MA.

These cards provide the Ethernet interface (access point) to the service provider customer equipment and enable the transport of the customer traffic over the optical network domain.

CTM supports Layer 2, Ethernet, service provisioning, and discovery. Before an Ethernet service can be provisioned, you must define an access domain, referred to in CTM as a Layer 2 topology. A Layer 2 topology consists of optical circuits with specific Layer 2 configurations. CTM supports Layer 2 topology provisioning and discovery. The following table summarizes the types of Layer 2 topology supported.

Table 7-49 Types of Layer 2 Topology Supported in CTM 

Type	Description	See
Point-to-point	A single point-to-point optical circuit with specific Layer 2 configuration.	Creating a Layer 2 Topology
Hub and spoke	In CTM, this refers to a maximum of two point-to-point Layer 2 topologies connected by a single ML-series card on which both point-to-point Layer 2 topologies are created. Note Other hub and spoke configurations can be created, including one where the ML-series card is placed at the spoke locations, with the G-series card providing an extension of the traffic to a Cisco 7600, which forms the hub of the architecture.
RPR	A chain of optical circuits connected through packet over SONET (POS) ports with a specific Layer 2 configuration.

The Ethernet service types supported by CTM are summarized in the following table.

Table 7-50 Types of Ethernet Services Supported in CTM 

Type	Description	See
UNI QinQ	Transparent LAN service. Service can be multiplexed with other UNI Dot1Q services.	Layer 2 Service Management Tasks
UNI Dot1Q	Services are multiplexed at the UNI.
NNI Dot1Q	Network-to-network interface. Services are multiplexed at the NNI.
UNI untagged	Service occupies the entire interface. For interface with a device that does not provide user VLAN ID capability.

---

Caution CTM provides optical circuit provisioning on the device through the CORBA interface and the data service through the Cisco IOS command-line interface (CLI). On the Cisco IOS side, CTM only recognizes the CLI configuration that is supported by CTM and ignores unsupported CLI configurations. CTM does not explicitly overwrite the existing configuration on the card. However, it can erase some of the configuration on the card without its knowledge. If you intend to use CTM to provision the supported services and plan to directly configure the nonsupported services on the card by passing CTM, consult Cisco first to prevent any configuration overwrite.

---

7.7.1  Layer 2 Topology Table Management Tasks

7.7.2  Initializing Layer 2 Cards

Before provisioning, you must first enable CTM communication with the Layer 2 cards. The cards to be managed should be initialized with a minimum configuration.

To allow CTM to communicate with Layer 2 cards, you must configure each card with a username, password, and hostname. You can customize this information in the Cisco IOS configuration file before loading it on the ML-series card.

When a Layer 2 topology is configured on NEs, CTM configures each ML-series card with a barebone configuration file. The barebone configuration file is the minimum configuration required for CTM to support the Layer 2 topology and Layer 2 services on it.

CTM provides the following barebone configuration files:

•barebone15454CLI_Security.txt—Use this base barebone configuration file for ML100, ML1000, or ML100X cards on ONS 15454 SONET and ONS 15454 SDH NEs. This file loads the ML card in microcode base mode. This barebone configuration file is the recommended default.

•barebone15454CLI_Enhanced_Security.txt—This configuration file provides microcode enhanced commands. Use this file to load a microcode enhanced image on ML100, ML1000, or ML100X cards on ONS 15454 SONET and ONS 15454 SDH NEs. The enhanced microcode image is required for CoS PM collection on ML cards.

•bareboneCLI_Generic.txt—Use this barebone configuration file for ML-100T-8 cards on ONS 15310 NEs. This file loads the ML-100T-8 card in microcode enhanced mode. Microcode base mode is not supported on the ML-100T-8 card. Also use this barebone configuration file for ONS 15454 SONET and ONS 15454 SDH R4.1.7 and earlier NEs, because these software versions do not support the microcode security feature.

---

Note The barebone configuration files are located on the server installation CD (Disk1/misc/). After installing the CTM server, the appropriate barebone configuration file is automatically copied by default to the opt/CiscoTransportManagerServer/IosConfig directory.

---

A sample Cisco IOS configuration file is shown below.

---

Note If you use a username/password combination other than CISCO15/CTM123+, it is recommended that you download this barebone configuration file to one of your ML-series cards, change the username and password to the ones you use, and manually copy the running configuration to all your ML-series cards. See Initializing Layer 2 Cards for more information.

You must perform the following steps before CTM can manage Layer 2 cards correctly:

---

Step 1 Initialize each card with the barebone configuration file through the CTM NE Explorer.

Step 2 Set the username and password, so that CTM will use the same username and password to communicate with the cards. This is done through the Control Panel > Security Properties tab for ONS 15454 SONET and ONS 15454 SDH NEs.

---

7.7.3  Backing Up and Restoring ML Configuration Files on Layer 2 Cards

You can back up and restore ML configuration files using CTC or the Cisco IOS commands on the ML-series cards.

•To store a backup version of the TCC2 (software) database on the workstation running CTC or on a network server, refer to Cisco ONS 15454 Procedure Guide.

•To load a Cisco IOS startup configuration file through CTC, refer to Cisco ONS 15454 SONET/SDH ML-Series Multilayer Ethernet Card Software Feature and Configuration Guide.

7.7.4  Naming Convention for Discovered Layer 2 Topologies

CTM follows a set naming convention when creating Layer 2 topologies.

If an RPR topology is created through CTM with the name toponame, the Layer 1 member circuits are named as follows: toponame.1CTML2, toponame.2CTML2, and so on.

During discovery, if Layer 1 circuits matching this naming convention are discovered, a Layer 2 topology with the name toponame is added to CTM.

If the CTM naming convention is not followed for discovered circuits, the RPR topology takes the name of one of the circuits in the RPR topology.

In the case of point-to-point topologies, the Layer 1 circuit has the same name as the topology. On the other hand, when a Layer 1 circuit between an ML and a non-ML series card is discovered, a point-to-point topology with the same name as the L1 circuit is added to the CTM database.

---

Note There are no VLAN naming conventions.

---

For RPR or point-to-point topologies created by creating Layer 1 circuits for a TL1 interface, the name appears as a numeric string. This numeric string is based on the unique number used to identify the circuits.

7.7.5  Provisioning the Layer 2 Topology

CTM allows you to create VCAT circuits and their constituent member circuits during Layer 2 topology creation. To support a Layer 2 topology, for RPR, CTM allows you to create all VCAT circuits (and contained member circuits), all CCAT circuits, or a combination of VCAT and CCAT circuits. For a point-to-point L2 topology you can create either a VCAT or a CCAT circuit.

The Layer 2 topology can be a point-to-point optical circuit, or RPR consisting of a chain of optical circuits, or hub and spoke consisting of multiple optical circuits connected in a hub and spoke fashion:

•Point-to-point topology—Select the source and destination of the point-to-point topology and provide the routing information for the SONET/SDH circuit. Both manual and automatic routing are supported. Table 7-52 lists the NE models and cards supported for L2 point-to-point topologies.

Table 7-52 NE Models and Cards Supported by CTM for L2 Topology

—	—	—	Yes1	No	No	—	—

1 Available only in LAN extension (LEX) encapsulation mode.

---

Note The E-series card requires a a field-programmable gate array (FPGA) upgrade to be compatible with ML-series and G-series cards. 16-bit cyclic redundancy check (CRC) is required.

---

---

Note The G-series to E-series card combination does not involve the L2 Topology wizard.

---

•RPR topology—Select the set of nodes that contains ML-series cards and then the set of ML-series cards. The ML-series order is important because it defines the order of the cards inside the rings. Once the ML-series cards have been selected, you are prompted with the set of SONET/SDH circuits that will be created underneath the Layer 2 topology. You can automatically route all the circuits or manually route the circuits that will be created underneath the Layer 2 topology. A minimum of two ML-series cards is required to configure an RPR.

•Hub and spoke topologies—In CTM, this refers to a maximum of two point-to-point Layer 2 topologies connected by a single ML-series card on which both point-to-point Layer 2 topologies are created. For point-to-point topologies, the following combinations of cards are supported:

–ML-series to ML-series

–ML-series to G-series

–ML-series to OC-n/STM-n

When deployed as hub and spoke, the ML-series cards can be placed at the spoke locations, with the G-series cards providing an extension of the traffic to a Cisco 7600, which forms the hub of the architecture. This arrangement provides a cost-effective way to interface to the Cisco 7600. Alternatively, the ML-series cards can be deployed at both the hub and the spoke sites. See the ML-series Metro Ethernet Design and Implementation Guide for network configurations.

---

Note When creating a Hub and Spoke topology, during creation of a PTP topology on an ML-series card that already has a PTP created on it, you cannot modify the base card configuration. This ensures that pre-existing base card configuration is retained.

---

When deployed as RPR, all sites contain ML-series cards.

The Create Circuit wizard is used to repair a Layer 2 topology, when the bottom circuit has been deleted or removed erroneously.

The Layer 2 Topology table reports the operational state and the state for each Layer 2 topology. For point-to-point topologies, the operational state reflects the state of the underlying optical circuit. For RPR topologies, the operational state can have one of the following values:

•In Service (IS)—RPR is in IS state when all the circuits underneath it are in IS state.

•In Service Partial (IS-Partial)—RPR is in IS-Partial state when only one circuit underneath it is in OOS state and all remaining circuits underneath it are in IS state.

•Out of Service (OOS)—RPR is in OOS state when more than two circuits underneath the RPR are in OOS state.

The Layer 2 Service Resync state provides the configuration synchronization state after discovery of the Layer 2 topology. The state can be In-Progress, Complete, Partially Complete, Layer 2 Service Not Ready, or Sync Failed. VLAN status is different and is available in the Layer 2 Services table.

CTM can discover a Layer 2 topology through the Create Layer 2 Topology wizard or Create Circuit wizard, through CTC, or through the TL1 interface.

A Layer 2 topology provisioned by this application is Layer 2 service enabled, meaning the optical circuit and the Cisco IOS configuration are set for subsequent Layer 2 services. However, a Layer 2 topology created through other means (such as through the Create Circuit wizard, CTC, or TL1 interface) is not Layer 2 service enabled. This is because the Cisco IOS configuration is missing. This type of Layer 2 topology must be Layer 2 service enabled if you want to provision Layer 2 services.

---

Note Layer 2 topology discovery in CTM depends on the underlying L1 circuit endpoints and not on the shared packet ring (SPR) interface ID configured on the ML card. If you change the SPR interface ID on a card used in an RPR topology so that the ID is a duplicate of an SPR interface ID configured on another card in the topology, CTM does not recognize the anomaly and does not display alarms.

---

---

Note Do not create an L2 topology or add a card to the L2 topology in mixed high-level data link control (HDLC) and generic framing procedure (GFP) modes. If you create an L2 topology using cards in different modes, traffic cannot flow through the topology. An L2 topology with cards in mixed modes generates an Encapsulation Mismatch alarm, which indicates that traffic cannot be passed through the ring.

---

---

Note Make sure to use a fresh barebone configuration file when creating an RPR L2 topology on a card that was initially created with a PTP topology, or when creating a PTP L2 topology on a card that was initially created with an RPR topology. It is always better to create an L2 topology with a fresh barebone configuration file loaded on the card, because CTM does not clear all of the old configuration on the card.

---

7.7.6  Viewing the L2 Topology Table

In the Domain Explorer window, choose Configuration > CTC-Based SONET NEs or CTC-Based SDH NEs > L2 Topology Table. The Layer 2 Topology table opens.

Figure 7-7 Layer 2 Topology Table

The Layer 2 Topology table displays all the configured Layer 2 topologies. It also reports the bandwidth settings for each Layer 2 topology. These are set for each Layer 2 topology and added through the Layer 2 topology wizard. The following bandwidth settings are reported:

•SP Management Bandwidth

•Committed information rate (CIR) Bandwidth

•Best Effort (BE) Bandwidth

•AVVID_CONTROL

•Multicast Priority Queuing

The following table describes the fields in the L2 Topology table.

Table 7-53 Field Descriptions for the Layer 2 Topology Table 

Column	Description
Layer 2 Topology Name	Displays the name of the topology.
Description	Displays the user-defined description of the topology.
Layer 2 Topology Type	Displays the topology type (point-to-point or RPR).
Layer 2 Topology Size	Displays the topology size. When the size of the circuit underneath is not the same, the value is Mixed.
Layer 2 Topology State	Displays the topology state (Complete, Incomplete, Complete-Wrapped, or Incomplete-Wrapped). The state of a point-to-point topology is always Complete. A complete RPR is one in which all the circuits linking the ML-series cards in the RPR are known by CTM. An incomplete RPR is one in which one or more ML-series cards in the RPR are missing. A complete RPR can become incomplete when one or more circuits forming the RPR are deleted by the user in CTC or another external interface. An incomplete RPR can become complete when all the circuits forming the RPR become known. The topology enters the Complete-Wrapped/Incomplete-Wrapped state if one or more PoS ports related to the topology are shut down.
Layer 1 Protection	Displays the L1 protection state, either Fully Protected or Unprotected.
Operational State	Displays the operational states of the circuits underneath. Values include: •In Service (IS)—All circuits are in service. •In Service-Partial (IS-Partial)—One circuit is out of service and the rest are in service. •Out of Service (OOS)—More than two circuits are out of service.
Layer 2 Service Resync Status	Displays the CTM status after trying to synchronize the configuration of all the ML-series cards in the topology. Values include: •Sync Failed—A card in the topology cannot resynchronize. •In Progress—CTM is trying to synchronize configuration information for all ML-series cards in the topology. •Complete—The Layer 2 service discovery is complete or the resynchronization is complete. In this state, the Layer 2 service information is synchronized with the NE. •L2Service NotReady—One of the cards in the topology does not have a base card configuration. •Partially Completed—If CTM cannot parse the configuration (for example, the configuration does not exist or is corrupt), the Layer 2 service discovery proceeds without acquiring the information from the ML card that has the problem. At the end of the discovery, the Layer 2 Service Resync Status is partially completed. You must reload the backed-up config file or the barebone config file (myconfig.txt) in the CTM server installation directory/IosConfig. You must reload the backed-up configuration file or the barebone configuration file from a synchronized ML card to the card that is not synchronized. Note If the barebone configuration file is loaded in an ML slot, all previous configuration on the card is erased. Note When the CTM server reboots and NEs are resynchronized, the CTM database resynchronizes the information related to the ML cards. After resynchronization, the L2 topology moves to the Complete state. This entire process takes some time, which causes the L2 topology to remain in L2Service NotReady or Sync Failed state until the resynchronization is complete.

7.7.7  Creating a Layer 2 Topology

Use the Create Layer 2 Topology wizard to set up a point-to-point or RPR topology.

---

Note CTM does not discover Layer 2 topologies when it discovers underlying circuits in the Partial state. If the Layer 2 Topology table does not display a particular topology, check the circuit state in the Circuit table. This is a known problem; Layer 2 topology discovery depends on circuits that are in the Discovered state only.

Table 7-54 Field Descriptions for the Create Layer 2 Topology Wizard 

Field	Description
Navigation Pane
The navigation pane on the left side of the wizard tells you where you are in the process of creating the L2 topology. The list of tasks shown initially is the default list of all possible tasks. As you move through the topology creation, you are taken to the appropriate task. You can use the navigation pane to jump quickly from one task to the next, or to an already visited task. Using the navigation pane is faster than using the Back and Next buttons, because you can jump over multiple panes in one step versus clicking Back or Next and moving through the panes sequentially. Tip As you proceed through the wizard, the panes you have visited are highlighted in white and identified by a number. Panes that are not applicable to the current creation sequence are shown in italics.

Layer 2 Topology Bandwidth
Note CTM allows you to enter multiple CoS values that are the same. This is harmless and is consistent with the ML CLI, which allows the entry of multiple CoS values but sets only one value.
Enable Multicast Group 1	Check the Enable Multicast Group1 check box to enable the Multicast Group 1 bandwidth and Class of Service text boxes and display the default values for those text boxes. By default these check boxes are unchecked during topology creation. Only when you choose to enter these values (by selecting any of these check boxes) can you enter values related to bandwidth and CoS for that multicast group. Note Multicast Group 2 is enabled only after enabling Multicast Group 1.
Multicast Group 1 (%)	Check the Enable Multicast Group1 check box to enable the Multicast Group 1 (%) bandwidth field. The default value (1%) is displayed. Edit this value as required. The valid range is from 1 to 95. Note The Multicast Group1 check box is unchecked by default. You must check the Enable Multicast Group1 check box before you can enter values in the Multicast Group 1 (%) field.
Class of Service	Check the Enable Multicast Group1 check box to enable the Class of Service field. The default value (4) is displayed. Edit this value as required. The valid range is from 0 to 7. Note The Enable Multicast Group1 check box is unchecked by default. You must check the Enable Multicast Group1 check box before you can enter values in the Class of Service field.
Enable Multicast Group 2	Check the Enable Multicast Group 2 check box to enable the Multicast Group 2 bandwidth and Class of Service text boxes and display the default values for those text boxes. Note Multicast Group 2 is enabled only after enabling Multicast Group 1.
Multicast Group 2 (%)	Check the Enable Multicast Group 2 check box to enable the Multicast Group 2 (%) bandwidth box. The default value (1%) is displayed. Edit this value as required. The valid range is from 1 to 95. Note The Enable Multicast Group 2 check box is unchecked by default. You must check the Enable Multicast Group 2 check box before you can enter values in the Multicast Group 2 (%) field.
Class of Service	Check the Enable Multicast Group 2 check box to enable the Class of Service field. The default value (6) is displayed. Edit this value as required. The valid range is from 0 to 7. Note The Enable Multicast Group 2 check box is unchecked by default. You must check the Enable Multicast Group 2 check box before you can enter values in the Class of Service field.
Low Latency Queue (%) (Read-only)	Low Latency Queueing (LLQ) is used for latency/delay-sensitive traffic such as voice. On ML-series and CE-series cards, there is no limit on the bandwidth allocation of LLQ at the L2 topology level. It is limited only by input rate limiting of specific ports. Because some ports might be trusted (external CoS becomes internal CoS), CTM does not know how much bandwidth might be used by LLQ, so it cannot reduce the calculated available bandwidth by the correct amount for the L2 topology. The actual available bandwidth allocation is the displayed available bandwidth value minus the amount (if any) that will be used for LLQ traffic.
SP Management (%)	Allows you to modify the bandwidth percentage used for the SP management traffic class. Values are 0 to 99. If the value is 0, CTM will not set this value in the CLI for the cards participating in the topology.
Committed Rate (%)	Allows you to modify the bandwidth percentage used for the CIR traffic class. Values are 0 to 99. If the value is 0, CTM will not set this value in the CLI for the cards participating in the topology.
AVVID Control (%)	Allows you to set the bandwidth percentage used for the AVVID control. Values are 0 to 99. If the value is 0, CTM will not set this value in the CLI for the cards participating in the topology.
Default Best Effort (%)	Allows you to modify the default bandwidth percentage used for the best-effort traffic class. Values are 0 to 99. By default, CTM will not allow you to proceed if you set this field to 0, and it will automatically assign any remaining bandwidth as the best-effort bandwidth. For example, if you enter 0, CTM will automatically assign 99 as the best-effort bandwidth.
Available (%) (Excluding LLQ)	Available bandwidth percentage.
CoS Commit (CoS values below this value are discard eligible)	Committed CoS. This value is set when applying the base card configuration and the value is the same on all the cards in the topology.
Class of Service	Class of service for Low Latency Queueing, SP Management, Committed Rate, and AVVID Control types of traffic. The valid range is from 0 to 7. If the SP Management, Committed Rate, and AVVID Control values are 0, this field is disabled.
RPR Circuit Segment Details (for RPR Layer 2 topologies)
Auto Route Entire RPR	Enable or disable automatic RPR routing. If enabled, CTM automatically determines the route for the RPR. Alternately, you can choose manual routing and specify all the intermediate hops on a hop-by-hop basis. Note Selecting Auto Route Entire RPR disables all specific routing options on this window. Auto Route Entire RPR is enabled only if Apply to All Circuits is selected. When Apply to All Circuits is unchecked, the Auto Route Entire RPR check box is grayed out.
Routing Preferences
Route Automatically	Enable or disable automatic route selection. If enabled, CTM automatically determines the route for the circuit. Alternately, you can disable automatic route selection and manually route the circuit where you specify all the intermediate hops on a hop-by-hop basis (up to 64 hops per circuit). You can manually route the circuit using either one of the following views: •Graphical—Provides a map view that displays the nodes and links you can use to create the circuits. You can select the nodes and links that you need for your circuit from the map view. •Textual—Provides a text view that lists the nodes you can use to create the circuits. Note If the source and destination of the circuit are on the same node, automatic routing is enabled.
Using Required Nodes/Links	(Available only if Route Automatically is checked) If checked, CTM automatically routes the circuit through the required nodes and/or links. There are two ways you can specify the required nodes and links. Choose one of the following: •Graphical •Textual
Review Route Before Creation	(Available only if Route Automatically is checked) Check this check box to review the route before it is created.
VT-DS3 Mapped Conversion	(Available only if Route Automatically is checked) If checked, you can route the circuit using the DS3XM12 card. This field does not apply to data cards (ML-series and CE-100T-8 cards).
Time Slot Restriction	If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable. In case of an RPR, you can set this one at a time, for each circuit segment of the RPR. Note This field is disabled when you check the Auto Route Entire RPR and Apply to All Circuits check boxes in the RPR Circuit Segment Details area. It is enabled when you uncheck the Auto Route Entire RPR and Apply to All Circuits check boxes and proceed to automatically route the individual circuit segments. Note Time Slot Restriction is not available for OCHCC and OCHNC circuit creation types. Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.
Fully Protected Layer 1	If selected, CTM ensures that the Layer 1 circuit is fully protected. If the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications: •Required—CTM ensures that the primary and alternate paths of the path-protected mesh networking (PPMN) portions of the complete circuit path are node-diverse. •Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the PPMN portions of the complete circuit path. •Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the PPMN portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.
Node-Diverse Path Required	CTM ensures that the primary and alternate paths of the PPMN portions of the complete circuit path are node-diverse.
Node-Diverse Path Desired	CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the PPMN portions of the complete circuit path.
Node-Diverse Path Don't Care	CTM creates primary and alternate paths that are link-diverse for the PPMN portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.
Protection Channel Access	To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, and check Protection Channel Access.
Dual Ring Interconnect	If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.
Diverse Shared Risk Link Group (SRLG)	If checked, fully protected circuits will be routed through working and protected links that do not share risk groups.

d. Time Slot Restriction—If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable.

---

Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.

---

e. Set the circuit path protection as follows:

•To route the circuit on a protected path, leave the Fully Protected Path check box checked (default) and proceed to the next substep. A fully protected circuit route is created based on the path diversity option you choose. Fully protected paths might or might not have SNCP path segments with primary and alternate paths. The path diversity options apply only to SNCP path segments, if any exist.

•To create an unprotected circuit, uncheck Fully Protected Path and go to Step 9.

•To route the circuit on an MS-SPRing protection channel, uncheck Fully Protected Path, check Protection Channel Access, and go to Step 9.

f. If you selected Fully Protected Path, choose one of the following options:

•Required—Ensures that the primary and alternate paths within the extended SNCP mesh network portions of the complete circuit path are nodally diverse.

•Desired—Specifies that node diversity is preferred, but if node diversity is not possible, link-diverse paths are created for the extended SNCP mesh network portion of the complete circuit path.

•Don't Care: Link Diverse Only—Specifies that only link-diverse primary and alternate paths for extended SNCP mesh network portions of the complete circuit path are needed.

•Dual Ring Interconnect—Provisions the circuit in a DRI topology. If selected, the other node specifications (Required, Desired, and Don't Care: Link Diverse Only) are disabled.

Step 9 In the Topology Bandwidth area, configure the Enable Multicast Group 1 and Enable Multicast Group 2 panes as required.

Step 10 In the Topology Bandwidth area, specify the following information:

•LLQ (%)—(Read-only) LLQ is used for latency/delay-sensitive traffic such as voice. On ML-series and CE-series cards, there is no limit on the bandwidth allocation of LLQ at the L2 topology level. It is limited only by input rate limiting of specific ports. Because some ports might be trusted (external CoS becomes internal CoS), CTM does not know how much bandwidth might be used by LLQ, so it cannot reduce the calculated available bandwidth by the correct amount for the L2 topology. The actual available bandwidth allocation is the displayed available bandwidth value minus the amount (if any) that will be used for LLQ traffic.

•SP Management (%)—Allows you to modify the bandwidth percentage used for the SP management traffic class. The sum of the percentage allocation for all traffic classes cannot exceed 99%. The bandwidth range for each traffic type has a minimum of 1% and a maximum of 99%.

•Committed Rate (%)—Allows you to modify the bandwidth percentage used for the CIR traffic class. The sum of the percentage allocation for all traffic classes cannot exceed 99%. The bandwidth range for each traffic type has a minimum of 1% and a maximum of 99%.

Step 14 If you specified the route type for a specific segment as Auto, continue to step 15. If you specified the route type for a specific segment as Manual, continue to step 16. If you selected to route the entire RPR automatically, complete the following information:

•Fully Protected Layer 1—If selected, CTM ensures that the circuit is fully protected. You can provision the circuit if the circuit must pass across unprotected links. CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications:

–Required—CTM ensures that the primary and alternate paths within the UPSR portions of the complete circuit path are node-diverse.

–Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path.

–Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.

7.7.9  Enabling a Layer 2 Service

To ensure that provisioning is available for Layer 2 services, the Layer 2 topology attributes must be configured correctly on the underlying optical circuits. A Layer 2 topology can be configured using the TL1 interface, CTC, or CTM. Layer 2 topologies configured using CTM are Layer 2 service-ready. Layer 2 topologies configured using the TL1 interface, CTC, or CTM Create Circuit wizard are not Layer 2 service-ready. Some examples of the latter case are:

•The optical circuit(s) of the Layer 2 topology are provisioned using the TL1 interface for Operations System Modifications for the Integration of Network Elements (OSMINE) compliance.

•You want to resize the optical circuits and instead of deleting the entire Layer 2 topology, you delete each circuit from an existing Layer 2 topology and add a new circuit with the new size until all circuits have been resized. This could result in a service outage.

•You want to add or delete an optical circuit from an existing Layer 2 topology.

---

Caution The CTM operation Configuration > Enable L2 Service is a traffic-affecting operation. There might be a loss of traffic for several seconds if there is any traffic passing through the service.

---

---

Step 1 Create a point-to-point or RPR topology with ML-series cards using the TL1 interface, CTC, or the Create Circuit wizard.

Step 2 In the Domain Explorer window, choose Configuration > CTC-Based SONET NEs or CTC-Based SDH NEs > L2 Topology Table. The L2 Topology table opens. The new topology will be listed and its Layer 2 Service Resync Status will be Layer 2 Service Not Ready.

Step 3 In the L2 Topology table, choose Configuration > Enable L2 Service. The Layer 2 Service Resync Status of the new topology becomes Complete.

---

Note If circuits forming the RPR are created with names following the CTM naming convention (for example, cktname.1CTML or cktname.2CTML), the RPR will have the name cktname. If the CTM naming convention is not followed, the RPR will have the name of one of the circuits in the RPR topology.

7.7.13  Inserting or Deleting a Card on an RPR Topology

This section describes how to insert or delete cards on an existing RPR topology.

---

Note After an add or delete card operation, the new circuits are listed in the Circuit table and have the system time, rather than CTML2, appended to the circuit name and circuit alias.

---

7.7.13.1  Inserting a Card into an Existing RPR Topology

---

Note During the addition or removal of an ML-series card on an RPR topology, the POS interfaces of the circuits being deleted are automatically shut down before deletion. After the new circuits are created, the POS interfaces are automatically re-enabled. Shutting down the POS ports upon card insertion or removal ensures Layer 2 protection, so that traffic between all other cards is not lost.

---

---

Note Station IDs uniquely identify ML cards in the RPR ring. While inserting an ML card into an RPR topology (whose resync state is Complete), the inserted ML card is assigned a station ID equal to the highest station ID in the existing RPR topology plus 1 (provided the highest station ID is less than or equal to 254). If the highest station ID is 254, unused station IDs in the topology less than 254 are used. The station ID of the ML card can be viewed in the Cisco IOS config file, within the interface SPR1 command block (applies only to an RPR topology). The following example shows a configuration snippet where the ML card is assigned a station ID of 1:

interface SPR1
no ip address
no keepalive
spr station-id 1
hold-queue 150 in
!

Under the Manual Route area, the Graphical radio button is selected by default.
Auto Route	•Using Required Nodes/Links—(Available only if Route Automatically is checked) If checked, CTM automatically routes the circuit through the required nodes and/or links. •Review Route Before Creation—(Available only if Route Automatically is checked) Check this check box to review the route before it is created. •VT-DS3 Mapper Conversion—(Available only if Route Automatically is checked) If checked, you can route the circuit using the DS3XM12 card.
Time Slot Restriction	If checked, you can enter an STS/VC4 value (to be used end-to-end) that CTM will use to automatically determine the route for the circuit. Circuit creation is rejected if the same STS/VC4 is not available end-to-end. If circuit creation is rejected, you can try circuit creation again using different values. The valid range you can enter is from 1 to 192 for SONET, or 1 to 64 for SDH networks. The default value is -1, indicating that STS routing is not applicable. Note Time Slot Restriction is not available for OCHCC and OCHNC circuit creation types. Note For VCAT circuits, you must enter multiple STS/VC4 values into the Time Slot Restriction field, in the Member Preferences table. The STS/VC4 values you enter into the Time Slot Restriction field must not be identical or circuit creation will fail, and the EID-1074 error message will be displayed.
Fully Protected Path	If selected, CTM ensures that the circuit is fully protected. You can provision the circuit in a UPSR DRI topology by checking Dual Ring Interconnect. Alternately, if the circuit must pass across unprotected links, CTM creates a primary and alternate circuit route (virtual UPSR) based on the following node diversity specifications: •Required—Ensures that the primary and alternate paths of the UPSR portions of the complete circuit path are node-diverse. •Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. •Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.
Node-Diverse Path	•Required—Ensures that the primary and alternate paths of the UPSR portions of the complete circuit path are node-diverse. •Desired—CTM attempts node diversity. If node diversity is impossible, CTM uses primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. •Don't Care: Link Diverse Only—CTM creates primary and alternate paths that are link-diverse for the UPSR portions of the complete circuit path. The paths might be node-diverse, but CTM does not check for node diversity.
Protection Channel Access	To route the circuit on a BLSR protection channel, if available, uncheck the Fully Protected Path check box, and check the Protection Channel Access check box.
Dual Ring Interconnect	If you selected Fully Protected Path and the circuit will be routed on a UPSR DRI, check the Dual Ring Interconnect check box. Note For DRI and iDRI manually created circuits, you must double-click the DRI span for it to become DRI. A single-click does not enable the DRI span.
Diverse Shared Risk Link Group (SRLG)	If checked, fully protected circuits will be routed through working and protected links that do not share risk groups.

7.7.13.2  Removing a Card from an Existing RPR Topology

To remove an ML card from a topology, at least two other ML cards must be part of the topology, because a valid topology has endpoints on at least two different NEs. For example, if you have two ML cards on a single NE, an L2 topology cannot be created across the two ML cards. If you have a topology with three ML cards (two cards on one NE and a third card on another NE), removal of the third card from the topology is not a valid operation because it reduces the number of NEs from two to one.

---

Note During the addition or removal of an ML-series card to or from an RPR topology, the POS interfaces of the circuits being deleted are automatically shut down before deletion. After the new circuits are created, the POS interfaces are automatically re-enabled. Shutting down the POS ports upon card insertion or removal ensures Layer 2 protection, so that traffic between all other cards is not lost.

7.7.14  Layer 2 Service Management Tasks

VLAN service is a collection of bridge groups within a Layer 2 topology. It can span multiple ML-series cards on a particular Layer 2 topology. In a point-to-point topology, no Layer 2 configuration is done on E-series, G-series, ML-100T-8, CE-100T-8, or OC-N cards. In an RPR topology, a VLAN can span the entire ring.

You can configure a VLAN service that consists of multiple service drops (Ethernet drops). Each service drop is classified according to:

•Port type—NNI or UNI

•Connection type—Dot1Q, QinQ, or Untagged

In a VLAN service, the recommended mix of port type and connection type is as follows:

•UNI QinQ and NNI Dot1Q

•UNI Dot1Q, UNI Untagged, and NNI Dot1Q

The following table summarizes the service drop configurations and associated parameters.

Table 7-60 Summary of Service Drop Configurations 

Port Type	Connection Type	Port VLAN ID	Layer 2 Tunneling (stp, cdp, vtp)	Mode (Dot1Q tunnel)	Encap (Dot1Q)

7.7.16  Provisioning ML-Series Cards to Receive SNMP Traps

---

Note In a gateway NE-end NE (GNE-ENE) setup when the ENEs are not connected to the LAN, the only way that the CTM server can communicate to the ENEs is through the GNE. When configuring the SNMP settings of the GNE, the GNE node must work as the SNMP proxy. The ENE nodes will forward the SNMP traps to the CTM server through the GNE. This means that the trap destination for the ENE nodes must be the GNE.

---

---

Step 1 In the Domain Explorer tree, select the NE that contains ML-series cards and choose Configuration > NE Explorer (or click the Open NE Explorer tool).

Step 2 In the node properties pane, click the Network tab.

Step 3 Click the SNMP subtab.

Step 4 If the NE is connected to the LAN-connected NE (LNE) or GNE, complete the following substeps:

a. Check the Allow SNMP Set check box.

b. If the LNE or GNE is acting as an SNMP proxy to forward traps from the ENE or DCC-connected NE, check the Allow SNMP Proxy check box.

c. Click Apply.

d. Click Create. The Create SNMP Trap Destination dialog box opens.

e. Complete the following fields in the Create SNMP Trap Destination dialog box:

•IP Address—Enter the IP address of the CTM server.

7.8  Managing QoS Profiles

QoS profiles provide a flexible and powerful way of specifying a QoS configuration. They allow you to define a number of sets of QoS classes for different types of service requirements. The major advantages of provisioning using QoS profiles are the ability to create similar types of services quickly using the same profile and the flexibility to customize certain values of a selected profile.

---

Note There is no association between the values of QoS profiles and values of QoS parameters used in an L2 service drop port instance.

---

Managing the QoS profiles is accomplished from the QoS Profile table.

7.8.1  QoS Profile Management Tasks

The following table describes the various tasks that can be carried out from the QoS Profile table and the recommended order in which to complete these tasks.

7.10.10  Automatic Node Setup

You should run the Automatic Node Setup (ANS) wizard based on the input supplied by the Cisco MetroPlanner application. The Cisco MetroPlanner application generates an entire network setup/configuration based on customer requirements. The Automatic Node Setup (ANS) wizard (launched from the Node Setup subtab) allows you to provision card and ANS parameters based on the content of an XML file that is generated by the Cisco MetroPlanner application. Using the contents of the XML file generated by the Cisco MetroPlanner application ensures that the NE configuration and optical parameters are correctly set.

You would normally run the ANS wizard when an NE has been inserted/discovered in CTM (as long as Cisco MetroPlanner has been used for the customer network).

The ANS wizard allows you to automatically preprovision (one NE at a time) the following:

•Card parameters

•ANS parameters

Preprovisioning is based on the output XML file you select that is generated by the Cisco MetroPlanner version 7.1 application that allows you to generate an XML configuration file for your network configuration. The Automatic Node Provisioning (ANP) XML file contains information that allows CTM to provision:

•OPT-AMP-L Role (booster/preamp)

•ANS provisioning parameters

7.11  What Is Connection Provisioning?

CTM supports device-level provisioning of the Cisco MGX Voice Gateway cards, lines, ports, and connections. The task of creating these connections is called connection provisioning.

CTM uses the Configuration Center to create new intrachassis connections, and display, modify, and delete existing connections. You select the desired connection endpoints and configure the connection type and class of service.

Connections in a switched voice application are AAL-5 connections for bearer and control paths. A Media Gateway Controller (MGC), or call agent, is required for these switching applications.

By managing connections using the Configuration Center, you can create and maintain soft permanent virtual circuits (SPVCs).

7.11.1  What Type of Connection Is Available?

The type of connection available on each card is listed in the following table.

Table 7-83 Supported Connection and Card Types 

Connection Type	Card
ATM	AXSM (T3, E3)
	AXSM/B (T3, E3)
	AXSM-E (T1, E1)
	MPSM-T1E1
	MPSM-T3E3-155
RPM	RPM-PR
	RPM-XF
VISM	VISM-PR-8T1E1
	VXSM 48T1E1
	VXSM-OC3
	VXSM-6T3

7.11.1.1  What Are the Supported Connection Service Types?

Connections can be made between:

•VISM- RPM

•VISM- ATM

•VISM-VISM

When adding a new connection from the Configuration Center application, the service type and protocol is SPVC.

For information about preparing a node for connection, see Chapter 3, "Building the Network."
