Create Circuits and VT Tunnels
This chapter explains how to create Cisco ONS 15454 electrical circuits, tunnels, OC-N circuits, Ethernet circuits, dense wavelength division multiplexing (DWDM) optical channel network connections, and virtual concatenated (VCAT) circuits. For additional information about ONS 15454 circuits, refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 Reference Manual.
Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

NTP-A127 Verify Network Turn Up
Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-24. If you are already logged in, continue with Step 2.
Step 2 From the View menu, choose Go to Network View. Wait for all the nodes that are part of the network to appear on the network map. (Large networks might take several minutes to display all the nodes.)
Note If this is the first time your computer has connected to this ONS 15454 network, the node icons are stacked on the left side of the graphic area, possibly out of view. Use the scroll bar under the network map to display the icons. To separate the icons press Ctrl and drag and drop the icon to the new location. Repeat until all the nodes are visible on the graphic area.
Step 3 Verify node accessibility. In the network view, all node icons must be either green, yellow, orange, or red.
If all network nodes do not appear after a few minutes, or if a node icon is gray with an IP address under it, do not continue. Look at the Net box in the lower right corner of the window. If it is gray, log in again, making sure not to check the Disable Network check box in the CTC Login dialog box. If problems persist, see "Turn Up Network" to review the network turn-up procedure appropriate for your network topology, or refer to the Cisco ONS 15454 Troubleshooting Guide for troubleshooting procedures.
Step 4 Verify DCC connectivity. All nodes must be connected by green lines. If lines are missing or gray in color, do not continue. See "Turn Up Network" and follow the network turn-up procedure appropriate for your network topology. Verify that all nodes have DCC connectivity before continuing.
Step 5 Click the Alarms tab to view alarm descriptions. Investigate and resolve, if necessary, all critical (red node icon) or major (orange node icon) alarms. Refer to the Cisco ONS 15454 Troubleshooting Guide to resolve alarms before continuing.
Step 6 From the View menu, choose Go to Home View. Verify that the node is provisioned according to your site or engineering plan:
a. View the cards in the shelf map. Verify that the ONS 15454 cards appear in the specified slots.
b. Click the Provisioning > General tabs. Verify that the node name, contacts, date, time, and Network Time Protocol/Simple Network Time Protocol (NTP/SNTP) server IP address (if used) are correctly provisioned. If needed, make corrections using the "NTP-A25 Set Up Name, Date, Time, and Contact Information" procedure on page 4-7.
c. Click the Network tab. Verify that the IP address, Subnet Mask, Default Router, Prevent LCD IP Config, and Gateway Settings are correctly provisioned. If not, make corrections using the "NTP-A169 Set Up CTC Network Access" procedure on page 4-9.
d. Click the Protection tab. Verify that protection groups are created as specified in your site plan. If the protection groups are not created, complete the "NTP-A170 Create Protection Groups" procedure on page 4-26.
e. If the node is in a BLSR, click the BLSR tab. (If the node is not in a BLSR, continue with Step f.) Verify that the following items are provisioned as specified in your site plan:
•BLSR type (2-fiber or 4-fiber)
•BLSR ring ID and node IDs
•Ring reversion time
•East and west card assignments
•4-fiber BLSRs: span reversion and east/west protect card assignments
If you need to make corrections, see the "A40 Provision BLSR Nodes" procedure for instructions.
f. Click the Security tab. Verify that the users and access levels are provisioned as specified. If not, see the "NTP-A30 Create Users and Assign Security" procedure on page 4-4 to correct the information.
g. If simple network management protocol (SNMP) is used, click the SNMP tab and verify the trap and destination information. If the information is not correct, see the "NTP-A87 Change SNMP Settings" procedure on page 12-33 to correct the information.
h. Click the DCC/GCC/OSC tab. Verify that DCCs were created to the applicable OC-N slots and ports (time-division multiplexing [TDM] nodes) or Optical Service Channel (OSC) slots and ports (DWDM nodes). If DCCs were not created for the appropriate OC-N or OSC slots and ports, see "Turn Up Network" and complete the turn-up procedure appropriate for your network topology.
i. Click the Timing tab. Verify that timing is provisioned as specified. If not, use the "NTP-A85 Change Node Timing" procedure on page 12-23 to make the changes.
j. Click the Alarm Profiles tab. If you provisioned optional alarm profiles, verify that the alarms are provisioned as specified. If not, see the "A71 Create, Download, and Assign Alarm Severity Profiles" procedure to change the information.
k. Verify that the network element defaults listed in the status area of the node view window are correct.
Step 7 Repeat Step 6 for each node in the network.
Step 8 Complete the appropriate circuit creation procedure from the NTP list in the "The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration." section.
Stop. You have completed this procedure.
NTP-A181 Create an Automatically Routed DS-1 Circuit
Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-24 at the node where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VT. VT cross-connects will carry the DS-1 circuit across the ONS 15454 network.
•Number of Circuits—Type the number of DS-1 circuits you want to create. The default is 1. If you are creating multiple circuits with the same slot and sequential port numbers, you can use Auto-ranged to create the circuits automatically.
•Auto-ranged—This check box is automatically selected if you enter more than 1 in the Number of Circuits field. Auto-ranging creates identical (same source and destination) sequential circuits automatically. Uncheck the box if you do not want CTC to create sequential circuits automatically.
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 8-1):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters, (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—VT1.5 is the default. You cannot change it.
•Bidirectional—Leave checked for this circuit (default).
•State—Choose a service 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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
Note If VT circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, VT circuits in OOS_AINS change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 Reference Manual for more information.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms are generated if in service (IS) ports are not receiving signals.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter the service level agreement (SLA) number. Otherwise, leave the field set to zero.
•Protected Drops—Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, or 1+1 protection. If you check this box, CTC displays only protected cards and ports as source and destination choices.
Figure 8-1 Setting Circuit Attributes for a DS-1 Circuit
Step 8 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors During Circuit Creation" task. Otherwise, continue with the next step.
Step 9 Click Next.
Step 10 Complete the "DLP-A95 Provision a DS-1 Circuit Source and Destination" task.
Step 11 In the Circuit Routing Preferences area (Figure 8-2), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.
•Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to include or exclude in the CTC-generated circuit route.
•Review Route Before Creation—Check this check box if you want to review and edit the circuit route before the circuit is created.
Figure 8-2 Setting Circuit Routing Preferences for a DS-1 Circuit
Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.
Circuits routed on BLSR protection channels are not protected. They are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection dual ring interconnect (DRI), check the Dual Ring Interconnect check box.
Step 15 If you selected Using Required Nodes/Spans in Step 11, complete the following substeps. If not, continue with Step 18.
a. Click Next.
b. In the Circuit Route Constraints area, click a node or span on the circuit map.
c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.
d. Repeat Step c for each node or span you wish to include or exclude.
e. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Notes Links lists and click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Step 16 Click Next. In the Create area of the VT Circuit Options panel, choose one of the following:
•VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15454 Reference Manual for more information.
•VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC-1, DS3XM-6, or OC-N port on a BLSR, 1+1, or unprotected node. VT aggregation points (VAPs) collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or digital access and cross-connect system (DACS). It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:
–Circuit source is STS grooming node—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC-1, DS3XM-6, or OC-N card.
–Circuit destination is STS grooming node—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC-1, DS3XM-6, or OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
Step 17 If you chose VT aggregation point, complete the following substeps. If not, continue with Step 18.
a. Click Next.
b. In the VT Aggregation Point Destination panel, click the node that you want to be the VAP destination, then click Add Destination.
Step 18 If you selected Review Route Before Creation in Step 11, complete the following substeps. If not, continue with Step 19.
a. Click Next.
b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "A182 Create a Manually Routed DS-1 Circuit" procedure.
Step 19 Click Finish. One of the following results occurs, depending on the circuit properties you chose in the Circuit Creation dialog box:
•If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuit(s), the Circuits window appears.
•If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 19 for each additional circuit. After completing the circuit(s), the Circuits window appears.
Step 20 In the Circuits window, verify that the new circuit(s) appear in the circuits list.
Step 21 Complete the "A135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 1 In the path protection area of the Circuit Attributes panel, set the path protection path selectors:
•Provision working go and return on primary path—Check this box to route the working path on one fiber pair and the protect path on a separate fiber pair. This feature only applies to bidirectional path protection circuits.
•Revertive—Check this 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 after the switch.
•Reversion time—If Revertive is checked, click the Reversion time field and choose a reversion time from the drop-down menu. The range is 0.5 to 12.0 minutes. The default is 5.0 minutes. 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.
•SF threshold—For STS circuits, set the path protection path-level signal failure bit error rate (BER) thresholds. Unavailable for VT circuits.
•SD threshold—For STS circuits, set the path protection path-level signal degrade BER thresholds. Unavailable for VT circuits.
•Switch on PDI-P—For STS circuits, check this box if you want traffic to switch when an STS payload defect indicator is received. Unavailable for VT circuits.
Step 2 Return to your originating procedure (NTP).
DLP-A95 Provision a DS-1 Circuit Source and Destination
Note After you have selected the circuit properties in the Circuit Source dialog box according to the specific circuit creation procedure, you are ready to provision the circuit source.
Step 1 From the Node drop-down menu, choose the node where the source will originate.
Step 2 From the Slot drop-down menu, choose the slot containing the DS1-14, DS1N-14, or DS3XM-6 card where the circuit will originate (Figure 8-3).
Figure 8-3 Defining the Circuit Source on a DS-1 Card
Step 3 Only if you chose DS3XM-6 as the card, choose the port from the Port drop-down menu.
Step 4 From the DS-1 drop-down menu, choose the source DS-1.
Step 5 If you need to create a secondary source, for example, a path protection bridge/selector circuit entry point in a multivendor path protection, click Use Secondary Source and repeat Steps 1 through 4 to define the secondary source. If you do not need to create a secondary source, continue with Step 6.
Step 6 Click Next.
Step 7 From the Node drop-down menu, choose the destination (termination) node.
Step 8 From the Slot drop-down menu, choose the slot containing the destination card. The destination is typically a DS-1 card. You can also choose an OC-N card to map the DS-1 to a VT1.5 for OC-N transport.
Step 9 Depending on the destination card, choose the destination port, STS, VT, or DS1 from the drop-down menus that appear based on the card selected in Step 8. See Table 8-2 for a list of valid options. CTC does not display ports, STSs, VTs, or DS1s already used by other circuits. If another user and you working on the same network choose the same port, STS, VT, port, or DS1 simultaneously, one of you receives a Path in Use error and is unable to complete the circuit. The user with the incomplete circuit needs to choose new destination parameters.
Step 10 If you need to create a secondary destination, for example, a path protection bridge/selector circuit exit point in a multivendor path protection, click Use Secondary Destination and repeat Steps 7 through 9 to define the secondary destination.
Step 11 Click Next.
Step 12 Return to your originating procedure (NTP).
NTP-A182 Create a Manually Routed DS-1 Circuit
Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-24 at the node where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose VT. VT cross-connects will carry the DS-1 circuit across the ONS 15454 network.
•Number of Circuits—Type the number of DS-1 circuits you want to create. The default is 1.
•Auto-ranged—Applies to automatically routed circuits only. If you entered more than 1 in the Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in Number of Circuits.)
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 8-1):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—VT1.5 is the default. You cannot change it.
•Bidirectional—Leave checked for this circuit (default).
•State—Choose a service 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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
Note If VT circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, VT circuits in OOS_AINS change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 Reference Manual for more information.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if in service (IS) ports are not receiving signals.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•Protected Drops—Check this box if you want the circuit routed on protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, or 1+1 protection. If you check this box, CTC shows only protected cards and ports as source and destination choices.
Step 8 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors During Circuit Creation" task. Otherwise, continue with the next step.
Step 9 Click Next.
Step 10 Complete the "DLP-A95 Provision a DS-1 Circuit Source and Destination" task.
Step 11 In the Circuit Routing Preferences area (Figure 8-2), uncheck Route Automatically.
Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 17.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 17.
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose a Node-Diverse Path option:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired— Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, check the Dual Ring Interconnect check box.
Step 15 Click Next. In the Create area of the VT Circuit Options panel, choose one of the following:
•VT tunnel on transit nodes—This option is available if the DS-1 circuit passes through a node that does not have a VT tunnel, or if an existing VT tunnel is full. VT tunnels allow VT circuits to pass through ONS 15454s without consuming cross-connect card resources. VT tunnels can carry 28 VT1.5 circuits. In general, creating VT tunnels is a good idea if you are creating many VT circuits from the same source and destination. Refer to the Cisco ONS 15454 Reference Manual for more information.
•VT aggregation point—This option is available if the DS-1 circuit source or destination is on an EC-1, DS3XM-6, or OC-N port on a BLSR, 1+1, or unprotected node. VT aggregation points (VAPs) collect DS-1s on an STS for handoff to non-ONS 15454 networks or equipment, such as an IOF, switch, or DACS. It allows VT1.5 circuits to be routed through the node using one STS connection on the cross-connect card matrix rather than multiple VT connections on the cross-connect card VT matrix. If you want to aggregate the DS-1 circuit you are creating with others onto an STS for transport outside the ONS 15454 network, choose one of the following:
–Circuit source is STS grooming node—Creates the VAP on the DS-1 circuit source node. This option is available only if the DS-1 circuit originates on an EC-1, DS3XM-6, or OC-N card.
–Circuit destination is STS grooming node—Creates the VAP on the DS-1 circuit destination node. This option is available only if the DS-1 circuit terminates on an EC-1, DS3XM-6, or OC-N card.
•None—Choose this option if you do not want to create a VT tunnel or a VAP. This is the only available option if CTC cannot create a VT tunnel or VAP.
Step 16 If you chose VT aggregation point, complete the following substeps. If not, continue with Step 18.
a. Click Next.
b. In the VT Aggregation Point Destination panel, click the node that you want to be the VAP destination, then click Add Destination.
Step 17 Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit. The circuit source node is selected. Green arrows pointing from the source node to other network nodes indicate spans that are available for routing the circuit.
Step 18 Complete the "DLP-A96 Provision a DS-1 or DS-3 Circuit Route" task for the DS-1 circuit you are creating.
Step 19 Click Finish. CTC compares your manually provisioned circuit route with the specified path diversity option you chose in Step 13. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path. If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 19 for each additional circuit.
Step 20 When all the circuits are created, the main Circuits window appears. Verify that the circuit(s) you created are correct.
Step 21 Complete the "A135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

Step 6 If the Fully Protect Path check box is checked in the Circuit Routing Preferences panel, you must:
•Add two spans for all path protection or unprotected portions of the circuit route from the source to the destination. If the Dual Ring Interconnect check box is checked, you must also add bidirectional spans between the DRI nodes. To do this, click a DRI node, then double-click the arrow pointing to the adjacent DRI node to create a bidirectional span.
•Add one span for all BLSR or 1+1 portions of route from the source to the destination.

–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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
Note If VT circuit source and destination ports are in an OOS_AINS, OOS_MT, or IS state, VT circuits in OOS_AINS change to IS even if a physical signal is not present. Refer to the Cisco ONS 15454 Reference Manual for more information.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if in service (IS) ports are not receiving signals.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•Protected Drops—Check this box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, or 1+1 protection. If you check this box, CTC displays only protected cards as source and destination choices.

Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, check the Dual Ring Interconnect check box.
Step 15 If you selected Using Required Nodes/Spans in Step 11, complete the following substeps; otherwise, continue with Step 16:
a. Click Next.
b. In the Circuit Route Constraints area, click a node or span on the circuit map.
c. Click Include to include the node or span in the circuit. Click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans determines the circuit sequence. Click spans twice to change the circuit direction.
d. Repeat Step c for each node or span you wish to include or exclude.
e. Review the circuit route. To change the circuit routing order, choose a node from the Required Nodes/Lines or Excluded Notes Links lists, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Note If a node or span stays gray, that node or span is required.
Step 16 If you selected Review Route Before Creation in Step 11, complete the following substeps; otherwise, continue with Step 17.
a. Click Next.
b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "A185 Create a Manually Routed DS-3 Circuit" procedure.
Step 17 Click Finish. One of the following actions occurs based on the circuit properties you selected:
•If you entered more than 1 in the Number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in the Number of Circuits field. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable at the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuit(s), the Circuits window appears.
•If you entered more than 1 in the Number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 17 for each additional circuit. After completing the circuit(s), the Circuits window appears.
Step 18 In the Circuits window, verify that the circuit(s) you just created appear in the circuits list.
Step 19 Complete the "A135 Test Electrical Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.
DLP-A208 Provision a DS-3 Circuit Source and Destination
Note After you have selected the circuit properties in the Circuit Source dialog box according to the specific circuit creation procedure, you are ready to provision the circuit source.
Step 1 From the Node drop-down menu, choose the node where the source will originate.
Step 2 From the Slot drop-down menu, choose the slot containing the DS-3 card where the circuit will originate. If you are configuring a DS-3 circuit with a transmux card, choose the DS3XM-6 card.
Step 3 From the Port drop-down menu, choose the source DS-3 or DS3XM-6 card as appropriate.
Step 4 If you need to create a secondary source, for example, a path protection bridge/selector circuit entry point in a multivendor path protection, click Use Secondary Source and repeat Steps 1 through 3 to define the secondary source. If you do not need to create a secondary source, continue with Step 5.
Step 5 Click Next.
Step 6 From the Node drop-down menu, choose the destination (termination) node.
Step 7 From the Slot drop-down menu, choose the slot containing the destination card. The destination is typically a DS3XM-6 or DS-3 card. You can also choose an OC-N card to the map DS-3 circuit to an STS.
Step 8 Depending on the destination card, choose the destination port or STS from the submenus that appear based on the card selected in Step 2. See Table 8-2 for a list of valid options. CTC does not display ports, STSs, VTs, or DS1s if they are already in use by other circuits. If you and a user working on the same network choose the same port, STS, VT, port, or DS1 simultaneously, one of you receives a Path in Use error and is unable to complete the circuit. The user with the incomplete circuit needs to choose new destination parameters.
Step 9 If you need to create a secondary destination, for example, a path protection bridge/selector circuit exit point in a multivendor path protection, click Use Secondary Destination and repeat Steps 6 through 8 to define the secondary destination.
Step 10 Click Next.

Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-24 at the node where you will create the circuit. If you are already logged in, continue with Step 3.
Step 2 If you want to assign a name to the circuit source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 4.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose STS. STS cross-connects will carry the DS-3 circuit across the ONS 15454 network.
•Number of Circuits—Type the number of DS-3 circuits you want to create. The default is 1.
•Auto-ranged—Applies to automatically routed circuits only. If you entered more than 1 in the Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in Number of Circuits.)
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 8-5):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave this field blank, CTC assigns a default name to the circuit.
•Size—Choose STS-1. For circuits on the DS3i-N-12 card, choose STS-3c. This sets a port group for ports 1, 4, 7, and 10 using 3 ports at any given time.
•Bidirectional—Leave this field checked (default).
•State—Choose a service 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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if in service (IS) ports are not receiving signals.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.
Step 8 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors During Circuit Creation" task.

Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.
Circuits routed on BLSR protection channels are not protected and are preempted during BLSR switches.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, click the Dual Ring Interconnect check box.
Step 15 Click Next. In the Route Review and Edit area, node icons appear so you can route the circuit manually. The green arrows pointing from the selected node to other network nodes indicate spans that are available for routing the circuit.
Step 16 Complete the "DLP-A96 Provision a DS-1 or DS-3 Circuit Route" task for the DS-3 you are creating.
Step 17 Click Finish. If you entered more than 1 in the Number of Circuits field, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 17 for each additional circuit.

•DS-1—If you are testing an unmultiplexed DS-1, you must have a DSX-1 panel or a direct DS-1 interface into the ONS 15454. Set the test set for DS-1. For information about configuring your test set, consult your test set user guide.
•DS-3—If you are testing a clear channel DS-3, you must have a DSX-3 panel or a direct DS-3 interface into the ONS 15454. Set the test set for clear channel DS-3. For information about configuring your test set, consult your test set user guide.
•DS3XM-6—If you are testing a DS-1 circuit on a DS3XM-6 card you must have a DSX-3 panel or a direct DS-3 interface to the ONS 15454. Set the test set for a multiplexed DS3. After you choose multiplexed DS-3, choose the DS-1 to test on the multiplexed DS-3. For information about configuring your test set, consult your test set user guide.
•EC-1—If you are testing a DS-1 on an EC1 card, you must have a DSX-3 panel or a direct DS-3 interface to the ONS 15454. Set the test set for an STS-1. After you choose STS-1, choose the DS1 to test the STS-1. For information about configuring your test set, consult your test set user guide.
Step 9 Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps 2 through 8 to make sure the test set and cabling is configured correctly.
Step 10 Inject errors from the test set. Verify that the errors appear at the source and destination nodes.
Step 11 Clear the PM counts for the ports that you tested. See the "DLP-A349 Clear Selected PM Counts" task on page 10-8 for instructions.
Step 12 Return the circuit and circuit ports to the state they were in at the beginning of the test:
a. Click the circuit you want to test, then choose Circuits > Set Circuit State from the Tools menu.
b. In the Set Circuit State dialog box, choose IS (in service), OOS (out of service) or OOS-AINS (auto in service) from the Target Circuit State drop-down menu.
c. Check the Apply to drop ports check box.
d. Click Apply.
Step 13 Perform the protection switch test appropriate to the SONET topology:
•For path protections, complete the "DLP-A94 Path Protection Switching Test" task.
•For BLSRs complete the "DLP-A91 BLSR Switch Test" task.
Step 14 Perform a bit error rate test (BERT) for 12 hours or follow your site requirements for length of time. For information about configuring your test set for BERT, see your test set user guide.
Step 15 After the BERT is complete, print the results or save them to a disk for future reference. For information about printing or saving test results, see your test set user guide.
Stop. You have completed this procedure.
NTP-A188 Create an Automatically Routed OC-N Circuit
Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-24 at the node where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 Click the Circuits tab, then click Create.
Step 5 In the Circuit Creation dialog box, complete the following fields:
•Circuit Type—Choose STS.
•Number of Circuits—Type the number of OC-N circuits you want to create. The default is 1. If you are creating multiple circuits with the same source and destination, you can use auto-ranging to create the circuits automatically.
•Auto-ranged—This check box is automatically selected when you enter more than 1 in the Number of Circuits field. Leave this check box selected if you are creating multiple OC-N circuits with the same source and destination and you want CTC to create the circuits automatically. Uncheck the box if you do not want CTC to create the circuits automatically.
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 8-12):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—Choose the OC-N circuit size: STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c, STS-48c, or STS-192c.
•Bidirectional—Leave checked for this circuit (default).
•State—Choose a service 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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if in service (IS) ports are not receiving signals.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•Protected Drops—Check this check box if you want the circuit routed to protected drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Step 8 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors During Circuit Creation" task.
Step 9 Click Next.
Step 10 Complete the "DLP-A97 Provision an OC-N Circuit Source and Destination" task for the OC-N circuit you are creating.
Step 11 In the Circuit Routing Preferences area (Figure 8-13), choose Route Automatically. Two options are available; choose either, both, or none based on your preferences.
•Using Required Nodes/Spans—Check this check box to specify nodes and spans to include or exclude in the CTC-generated circuit route.
•Review Route Before Creation—Check this check box to review and edit the circuit route before the circuit is created.
Figure 8-13 Setting Circuit Routing Preferences for an OC-N Circuit
Step 12 To set the circuit path protection, complete one of the following:
•To route the circuit on a protected path, leave Fully Protected Path checked and continue with Step 13. CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have path protection path segments (with primary and alternate paths), and the path diversity options apply only to path protection path segments, if any exist.
•To create an unprotected circuit, uncheck Fully Protected Path and continue with Step 15.
•To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path, check Protection Channel Access, click Yes in the Warning dialog box, then continue with Step 15.
Step 13 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection, choose one of the following:
•Nodal Diversity Required—Ensures that the primary and alternate paths within path protection portions of the complete circuit path are nodally diverse.
•Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
•Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path protection portions of the complete circuit path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Step 14 If you selected Fully Protected Path in Step 12 and the circuit will be routed on a path protection DRI, click the Dual Ring Interconnect check box.
Step 15 If you selected Using Required Nodes/Spans in Step 11, complete the following substeps. If not, continue with Step 16:

b. In the Circuit Route Constraints area, click a node or span on the circuit map.
c. Click Include to include the node or span in the circuit, or click Exclude to exclude the node or span from the circuit. The order in which you choose included nodes and spans is the order in which the circuit is routed. Click spans twice to change the circuit direction.
d. Repeat Step c for each node or span you wish to include or exclude.
e. Review the circuit route. To change the circuit routing order, choose a node in the Required Nodes/Lines or Excluded Notes Links lists, then click the Up or Down buttons to change the circuit routing order. Click Remove to remove a node or span.
Step 16 If you selected Review Route Before Creation in Step 11, complete the following substeps; otherwise, continue with Step 17:
a. Click Next.
b. Review the circuit route. To add or delete a circuit span, choose a node on the circuit route. Blue arrows show the circuit route. Green arrows indicate spans that you can add. Click a span arrowhead, then click Include to include the span or Remove to remove the span.
c. If the provisioned circuit does not reflect the routing and configuration you want, click Back to verify and change circuit information. If the circuit needs to be routed to a different path, see the "A189 Create a Manually Routed OC-N Circuit" procedure to assign the circuit route yourself.
Step 17 Click Finish. One of the following occurs, based on the circuit properties you provisioned in the Circuit Creation dialog box:
•If you entered more than 1 in the number of Circuits field and selected Auto-ranged, CTC automatically creates the number of circuits entered in Number of Circuits. If auto-ranging cannot complete all the circuits, for example, because sequential ports are unavailable on the source or destination, a dialog box appears. Set the new source or destination for the remaining circuits, then click Finish to continue auto-ranging. After completing the circuit(s), the Circuits window appears.
•If you entered more than 1 in the number of Circuits field and did not choose Auto-ranged, the Circuit Creation dialog box appears so you can create the remaining circuits. Repeat Steps 5 through 17 for each additional circuit. After completing the circuit(s), the Circuits window appears.
Step 18 In the Circuits window, verify that the circuit(s) you created appear in the circuits list.
Step 19 Complete the "A62 Test OC-N Circuits" procedure. Skip this step if you built a test circuit.
Stop. You have completed this procedure.

–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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
•Apply to drop ports—Check this box if you want to apply the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if in service (IS) ports are not receiving signals.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations are unavailable.
•Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is, to ONS 15454 cards that are in 1:1, 1:N, or 1+1 protection. If you check this check box, CTC provides only protected cards as source and destination choices.

Step 10 Define the circuit attributes:
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Size—Choose the circuit size. Valid circuit sizes for an Ethernet multicard circuit are STS-1, STS-3c, and STS6c. Valid circuit sizes for an Ethernet single-card circuit are STS-1, STS-3c, STS6c, and STS12c.
•Bidirectional—Leave the default unchanged (checked).
•State—Choose IS (in service). Ethergroup circuits are stateless and always in service.
•Apply to drop ports—Uncheck this box; states cannot be applied to E-Series Ethernet card ports.
•Create cross-connects only (TL1-like)—Uncheck this box; it does not apply to Ethernet circuits.
•Inter-domain (UCP) SLA—If the circuit will travel on a UCP channel, enter the service level agreement number. Otherwise, leave the field set to zero.
•Protected Drops—Leave the default unchanged (unchecked).
Step 11 If the circuit will be routed on a path protection, complete the "DLP-A218 Provision Path Protection Selectors During Circuit Creation" task.
Layer 1 SONET protection does not extend to multicard EtherSwitch circuits on path protection.
A TCC2 card reset disrupts single-card and multicard Etherswitch circuits for 45 seconds to two minutes. During this time a spanning tree topology is created by the newly activated TCC2 card.
Step 12 Click Next.
Step 13 Provision the circuit source:
a. From the Node drop-down menu, choose one of the EtherSwitch circuit endpoint nodes. (Either end node can be the EtherSwitch circuit source.)
b. From the Slot drop-down menu, choose one of the following:
•If you are building a multicard EtherSwitch circuit, choose Ethergroup.
•If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.
Step 14 Click Next.
Step 15 Provision the circuit destination:
a. From the Node drop-down menu, choose the second EtherSwitch circuit endpoint node.
b. From the Slot drop-down menu, choose one of the following:
•If you are building a multicard EtherSwitch circuit, choose Ethergroup.
•If you are building a single-card EtherSwitch circuit, choose the Ethernet card where you enabled the single-card EtherSwitch.
Step 16 Click Next.
Step 17 In the Circuit VLAN Selection area, click New VLAN. If the desired VLAN already exists, continue with Step 20.
Tip You can also add VLANs in network view by choosing Tools > Manage VLANs. In the All VLANs dialog box, click the Create button to open the Define New VLAN dialog box.
Step 18 In the Define New VLAN dialog box, complete the following:
•VLAN Name—Assign an easily identifiable name to your VLAN.
•VLAN ID—Assign a VLAN ID. The VLAN ID should be the next available number between 2 and 4093 that is not already assigned to an existing VLAN. Each ONS 15454 network supports a maximum of 509 user-provisionable VLANs.
•Topology ID—Choose the topology ID from the drop-down menu.
Step 19 Click OK.
Step 20 In the Circuit VLAN Selection area, highlight the VLAN name and click the arrow button (>>) to move the available VLAN(s) to the Circuit VLANs column.
Step 21 If you are building a single-card EtherSwitch circuit and want to disable spanning tree protection on this circuit, uncheck the Enable Spanning Tree check box and click OK in the Disabling Spanning Tree dialog box. The Enable Spanning Tree box remains checked or unchecked for the creation of the next single-card, point-to-point Ethernet circuit.
Disabling spanning-tree protection increases the likelihood of logic loops on an Ethernet network.
Turning off spanning tree on a circuit-by-circuit basis means that the ONS 15454 is no longer protecting the Ethernet circuit and that the circuit must be protected by another mechanism in the Ethernet network.
Multiple circuits with spanning tree protection enabled incur blocking if the circuits traverse the same E-Series card and use the same VLAN.
Note Spanning-tree rules prevent users from creating new circuits or modifying existing circuits if the circuits do not meet certain VLAN assignment constraints. If the VLAN set of the new circuit overlaps existing circuits, the same spanning-tree instance is used for all circuits. If the VLAN set of the new circuit overlaps with VLAN sets of existing circuits with different spanning-tree instances, the VLAN assignment fails. Cisco recommends that you plan VLAN assignments so that circuits with larger VLAN sets and a higher chance of overlap are added first. This means that if a circuit with an overlapping VLAN set is added, it collapses into the same spanning tree. To view circuits mapped to a spanning tree and their VLAN assignments, see the "DLP-A430 View Spanning Tree Information" task on page 11-11.
Note You can disable or enable spanning tree protection on a circuit-by-circuit basis only for single-card, point-to-point Ethernet circuits. Other E-Series Ethernet configurations disable or enable spanning tree on a port-by-port basis.
Step 22 Click Next.
Step 23 In the left pane of the Circuit Routing Preferences panel, confirm that the following information is correct:
•Circuit name
•Circuit type
•Circuit size
•ONS 15454 nodes
Step 24 If the information is not correct, click the Back button and repeat Steps 8 through 23 with the correct information. If the information is correct, check Route Automatically.
Step 25 Click Finish.
Step 26 Complete the "DLP-A221 Provision E-Series Ethernet Ports for VLAN Membership" task.

Step 7 Return to your originating procedure (NTP).
DLP-A220 Provision E-Series Ethernet Ports
Step 1 In node view, double-click the Ethernet card that you want to provision.
Step 2 Click the Provisioning > Ether Port tabs.
Step 3 For each Ethernet port, provision the following parameters:
•Port Name—If you want to label the port, type a port name.
•Mode—Choose the appropriate mode for the Ethernet port:
–Valid choices for the E100T-12/E100T-G card are Auto, 10 Half, 10 Full, 100 Half, or 100 Full.
–Valid choices for the E1000-2/E1000-2-G card are 1000 Full or Auto.
Note Both 1000 Full and Auto mode set the E1000-2 port to the 1000 Mbps and Full duplex operating mode; however, flow control is disabled when 1000 Full is selected. Choosing Auto mode enables the E1000-2 card to autonegotiate flow control. Flow control is a mechanism that prevents network congestion by ensuring that transmitting devices do not overwhelm receiving devices with data. The E1000-2 port handshakes with the connected network device to determine if that device supports flow control.
•Enabled—Check this check box to activate the corresponding Ethernet port.
•Priority—Choose a queuing priority for the port. Options range from 0 (Low) to 7 (High). Priority queuing (IEEE 802.1Q) reduces the impact of network congestion by mapping Ethernet traffic to different priority levels. Refer to the priority queuing information in the Cisco ONS 15454 Reference Manual. This parameter does not apply to an E-Series card in port-mapped mode.
•Stp Enabled—Check this check box to enable the Spanning Tree Protocol (STP) on the port. This parameter does not apply to an E-Series card in port-mapped mode. Refer to the spanning tree information in the Cisco ONS 15454 Reference Manual.
Step 4 Click Apply.
Step 5 Repeat Steps 1 through 4 for all other cards in the VLAN, or if the E-Series card is in port-mapped mode, repeat Steps 1 through 4 for the other card in a point-to-point circuit.
Step 6 Your Ethernet ports are provisioned and ready to be configured for VLAN membership. See the "DLP-A221 Provision E-Series Ethernet Ports for VLAN Membership" task for instructions.
Step 7 Return to your originating procedure (NTP).
DLP-A221 Provision E-Series Ethernet Ports for VLAN Membership
Step 1 In node view, double-click the E-Series card graphic to open the card.
Step 2 Click the Provisioning > Ether VLAN tabs.
Step 3 To put a port in a VLAN:
a. Click the port and choose either Tagged or Untag.
b. If a port is a member of only one VLAN, choose Untag from the Port column in the VLAN's row. Choose -- for all the other VLAN rows in that Port column.
Note The VLAN with Untag selected can connect to the port, but other VLANs cannot access that port.
c. Choose Tagged at all VLAN rows that need to be trunked. Choose Untag at VLAN rows that do not need to be trunked, for example, the default VLAN.
Note Each Ethernet port must be attached to at least one untagged VLAN. A trunk port connects multiple VLANs to an external device, such as a switch, which also supports trunking. A trunk port must have tagging (IEEE 802.1Q) enabled for all the VLANs that connect to that external device.
Step 4 After each port is in the appropriate VLAN, click Apply. Table 8-4 lists VLAN settings.
.
Note If Tagged is chosen, the attached external Ethernet devices must recognize IEEE 802.1Q VLANs.
Note Both ports on an E1000-2/E1000-2-G card cannot be members of the same VLAN.

–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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
•Apply to drop ports—Check this check box if you want to apply the state chosen in the State field (IS or OOS-MT only) to the Ethernet circuit source and destination ports. You cannot apply OOS-AINS to E-Series Ethernet card ports. CTC applies the circuit state to the ports only if the circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the circuit, the circuit must be the first circuit to use the drop port. If not, a Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Note Loss of signal alarms appear if in service (IS) ports are not receiving signals.
•Create cross-connects only (TL1-like)—Uncheck this box.

NTP-A264 Create an Automatically Routed VCAT Circuit
Note You can provision a maximum of two VCAT circuits for ML-Series cards.
Note For FC_MR-4 cards with a line rate 2-Gbps fiber channel, an equivalent VCAT circuit does not exist. A contiguous STS-48c circuit is used instead. FC_MR-4 cards with a line rate 1-Gbps fiber channel use eight VCAT members, each member using an STS-3c or STS-24c circuit. Software Release 4.6 supports line rate connections, not subrate connections. As a result, you cannot change the rate from 1-Gbps to 2-Gbps if the circuit rate is STS-24c.
Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-24 at the node where you will create the VCAT circuit. If you are already logged in, continue with Step 2.
Step 2 From the View menu, choose Go to Network View.
Step 3 Click the Circuits tab, then click Create.

Step 6 Define the circuit attributes (Figure 8-18):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Type—Displays the circuit type you chose in Step 4. You cannot change it.
•Bidirectional—Checked is the default. You cannot change it.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit.
•State—Choose a service 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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
•Apply to drop ports—Not applicable.
•Symmetric—Checked is the default. You cannot change it.
•Member size—Choose the member size: STS-1c, STS-3c, or STS-12c. For FC_MR-4 cards, only STS-3c is available.
•Num. of members—For VCAT circuits on FC_MR-4 cards, choose 8. For VCAT circuits on ML-Series cards, choose 2.
•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.

Step 10 In the Member Preferences area, complete the following:
•Number—Type a number (between 1 and 256) to identify the member.
•Name—Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.
•Protection—Choose the member protection type:
–Fully Protected—Routes the circuit on a protected path; path protection is not supported.
–Unprotected—Creates an unprotected circuit.
–PCA—Routes the circuit on a BLSR protection channel.
–Set protection for all members—Allows you to choose the same protection type for all members.
Note If a member is unprotected, all members must be unprotected.
Step 11 Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.

NTP-A265 Create a Manually Routed VCAT Circuit
Note You can provision a maximum of two VCAT circuits for ML-Series cards.
Note For FC_MR-4 cards with a line rate 2-Gbps fiber channel, an equivalent VCAT circuit does not exist. A contiguous STS-48c circuit is used instead. FC_MR-4 cards with a line rate 1-Gbps fiber channel use eight VCAT members, each member using an STS-3c or STS-24c circuit.
Step 1 Complete the "DLP-A60 Log into CTC" task on page 3-24 at the node where you will create the circuit. If you are already logged in, continue with Step 2.
Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit, complete the "DLP-A314 Assign a Name to a Port" task. If not, continue with Step 3.
Step 3 From the View menu, choose Go to Network View.
Step 4 In the Circuit Creation dialog box, choose STS-V from the Circuit Type drop-down menu.
Step 5 Click Next.
Step 6 Define the circuit attributes (Figure 8-18):
•Name—Assign a name to the circuit. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
•Type—Displays the circuit type you chose in Step 4. You cannot change it.
•Bidirectional—Checked is the default. You cannot change it.
•Create cross-connects only (TL1-like)—Check this box if you want to create one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot assign a name to the circuit.
•State—Choose a service 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 (IS).
–OOS-MT—The circuit is in a maintenance state. The maintenance state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use OOS-MT for circuit testing or to suppress circuit alarms temporarily. Change the state to IS, OOS, or OOS-AINS when testing is complete. See the "DLP-A230 Change a Circuit State" task on page 11-13.
•Apply to drop ports—Not applicable.
•Symmetric—Checked is the default. You cannot change it.
•Member size—Choose the member size: STS-1c, STS-3c, or STS-12c. For FC_MR-4 cards, only STS-3c is available.
•Num. of members—For VCAT circuits on FC_MR-4 cards, choose 8. For VCAT circuits on ML-Series cards, choose 2.
•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.
Step 7 Click Next.
Step 8 Complete the "DLP-A324 Provision a VCAT Circuit Source and Destination" task for the VCAT circuit you are creating.
Step 9 In the Circuit Routing Preferences area (Figure 8-19), uncheck Route Automatically.
Step 10 In the Member Preferences area, complete the following:
•Number—Type a number (between 1 and 256) to identify the member.
•Name—Type a unique name to identify the member. The name can be alphanumeric and up to 48 characters (including spaces). If you leave the field blank, CTC assigns a default name to the circuit.
•Protection—Choose the member protection type:
–Fully Protected—Routes the circuit on a protected path; path protection is not supported.
–Unprotected—Creates an unprotected circuit.
–PCA—Routes the circuit on a BLSR protection channel.
–Set protection for all members—Allows you to choose the same protection type for all members.
Note If a member is unprotected, all members must be unprotected.
Step 11 Click Next. If you chose Fully Protected or PCA, click OK to continue. If not, continue with the next step.
Step 12 In the Route Review and Edit area, node icons appear so you can route the circuit manually.
Step 13 Complete the "DLP-A325 Provision a VCAT Circuit Route" task.
Step 14 Click Finish. If the path does not meet the specified path diversity requirement, CTC displays an error message and allows you to change the circuit path.
Step 15 When all the circuits are created, the main Circuits window appears. Verify that the circuit you created appear in the window.
Stop. You have completed this procedure.
