Release Notes for Cisco ONS 15454
Release 7.2
November, 2007
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.
Release notes address closed (maintenance) issues, caveats, and new features for the Cisco ONS 15454 SONET multiplexer. For detailed information regarding features, capabilities, hardware, and software introduced with this release, refer to the "Release 7.2" version of the Cisco ONS 15454 DWDM Installation and Operations Guide; and the "Release 7.2" version of the Cisco ONS 15454 Procedure Guide; Cisco ONS 15454 Reference Manual; Cisco ONS 15454 Troubleshooting Guide; and Cisco ONS 15454 SONET TL1 Command Guide.

Caveats without tracking numbers are provided to point out procedural or situational considerations when deploying the product.
Alarms
CSCsj26750
When the card type in CTC is changed from DS1_14 to DS1_E1_56 with DS1-14 physical card in the slot, the LED in DS1_14 card will show Act (Green) LED, instead of Fail (RED) LED. This issue will be resolved in a future release.
Hardware
CSCsd94528
Intermittent Packet drops can occur when connecting a Catalyst Switch to a CE1000 during auto-negotiation.
For more information review the following field notice:
This issue is resolved in Release 8.0.
CSCed18803
Rarely, the non-enhanced Muxponder unit does not pass Jitter Tolerance test from Trunk port to client port as per ITU-T G.825, 2 Mb/s mask, at the 10 Hz specific setpoint. The Muxponder should be configured with G.709 Off, FEC Off and Trunk signal provided by external Jitter test box, and the unit client port output monitored for errors, to see this issue. This issue will not be resolved. Note that in normal network configurations the muxponder is operated with G.709 and FEC turned on, and the jitter tolerance tests pass.
CSCuk48503
Under specific conditions the non-enhanced MXPD does not pass the Telcordia GR-253/G.825 Jitter generation mask test on 10G TX Trunk port. The 2.5 G TX Client jitter generation is always within mask and does not exhibit this issue. This occurs only when, in SONET mode, there is no FEC, no G.709, and client interfaces are looped back, with non-synchronous clocking, and the jitter testbox TX connected to Trunk RX port, while the jitter testbox RX is connected to the Trunk TX port. The jitter testbox TX clock recovers from RX with an additional 5 ppm offset added. This issue will not be resolved.
CSCuk44284
An optical connector and optical attenuators inserted into the SFP may force the fiber against the shelf door when it is closed. Use the following types of optical connectors and optical attenuators when connecting to the SFP:
•
•
–

Jitter Performance with XC10G
During testing with the XC10G, jitter generation above 0.10 UI p-p related to temperature gradient testing has been observed. This effect is not expected to be seen under standard operating conditions. Changes are being investigated to improve jitter performance in a future release. Tracking numbers related to this issue include CSCdv50357, CSCdv63567, CSCdv68418, CSCdv68441, CSCdv68389, CSCdv59621, and CSCdv73402.
CSCdz49928
When using KLM type fuses with specific types of fuse and alarm panels, the PWR-REDUN alarm may not be displayed once the fuse is blown. A KLM fuse does not have a blown fuse indicator built into it. As a result, the blown fuse detection circuitry on the FAP may continue to provide voltage on its output despite a blown fuse.
Maintenance and Administration
Caution

Note
CSCsd47626
Bulk deletion of Low Order Server Trails can cause a TCC card to reset. To avoid this delete low order server trails one by one. This issue will be resolved in Release 8.0.
CSCsc00811
Deleting a monitor circuit and its parent at the same time might result in a PARTIAL parent circuit. To avoid this, delete the monitor circuit before deleting the parent circuit. This issue will not be resolved
CSCsc36281
The software Activating progress popup window might fail to automatically close during multiple or parallel software activations. If this occurs you must manually close the popup window. The following error message might also be raised and need to be closed:
"EID-3251 Unable to complete requested action. Unable to activate because the working software version is newer than the protect one."
To ensure that all nodes are using the correct software version you should close and restart CTC. This issue will be resolved in a future release.
Mismatch Equipment Attributes Alarm on EIA
In Release 6.0 a Mismatch Equipment Attributes (MEA) alarm is raised incorrectly against the B-Side BIC (EIA) on an ONS 15454 node using the 15454-SA-HD (high density) chassis with 1BNCB48, 1BNCB24, or 1SMBB84 EIAs installed. The 1BNCB48, 1BNCB24, and 1SMBB84 EIA panels are compatible with the 15454-SA-HD shelf assembly; however, the software in Release 6.0 fails to recognize their compatibility. The MEA alarm raised as a result of this issue is not service impacting, but does cause a standing alarm.
As a workaround to the standing alarm, you can change the BIC-MEA alarm severity by creating and using a custom alarm profile following the steps that apply for your network in the NTP-A71 Create, Download, and Assign Alarm Severity Profiles procedure of the Manage Alarms chapter in the Cisco ONS 15454 Procedure Guide, Release 6.0. This issue will be resolved in Release 6.1.
CSCeh84908
A CTC client session can disconnect from an ONS node during simultaneous deletion of large numbers of VT level circuits (3000+). Connectivity to the node will recover without any user action. If the condition persists, restart the CTC session to reconnect. This issue is under investigation.
CSCei36415
When retrieving GBIC inventory for the FC_MR-4, nothing is returned for the CLEI code. In a future release, enhanced inventory information will be available for ONS GBICs. This will include the CLEI code.
CSCeh92201
When you create a bidirectional BLSR-path protection IDRI circuit using auto-routing and select the PCA option for secondary spans, the circuit is created over working BLSR spans and does not use PCA spans. To enforce the use of the PCA option, provision the circuit using manual routing. This issue will not be resolved.
CSCee96164
The Wait To Restore (WTR) alarm does not appear to be raised for as long as the WTR timer is set for. The WTR is raised correctly, but the alarm is hidden for the first 12 seconds due to the clear soaking time for a CLDRESTART alarm. You can see this behavior if you set up a 1+1 bidirectional revertive protection group, remove the working card, and then reinsert the card. There are no plans to change this behavior.
CSCee25136
If you create a PM schedule with the Start time for the PM report equal to 00:00 (in TL1, "0-0"), after a few minutes the PM report start time might change to 23:59 (in TL1, "23-59"). This issue will not be resolved.
CSCed23484
A user might remain in the logged-in state after rebooting the PC while logged into a node running CTC. The user login will time out once the "Idle User Timeout" limit is up. Alternatively, you can log in as a superuser and force the user off. This issue will not be resolved.
CSCds88976
When a new circuit is created around a ring (path protection or BLSR), the SD BER or SF BER alarm can be raised depending on the order in which the spans are provisioned. The alarms will eventually clear by themselves. Traffic is not affected. This issue will not be resolved.
CSCdu82934
When you auto-route a VT circuit on an ONS 15454 node, a path is computed based on the availability of STSs on the nodes involved. This selection process, when combined with a lack of VT matrix (or STS-VT connections) on an auto-route selected node, can result in the VT circuit creation failing with the message "unable to create connection object at node." To correct this situation, manually route VT circuits in cases when auto-routing fails. The error message will indicate which node is at issue.
CSCef28522
When you inject errors on a splitter protection card in the node's working port, CVL and ESL are incremented for the working and protect far end ports. This issue will not be resolved.
CSCuk49106
The amplifier gain set point shown by CTC and the actual measured amplifier gain differ. The following steps illustrate this issue.
Step 1
Step 2
The APC procedure does not check consistency between the gain set point and the real gain, but rather only verifies the amplifier total output power. As a workaround, manual setting can be performed to align these values, although the discrepancy does not impact the normal functioning of the amplifier. This issue will not be resolved.
CSCef05162
Clearing the displayed statistics for a port will also clear the displayed history for that port. Clearing the displayed statistics for all ports will also clear the displayed history for all ports. There is no warning message from the TCC2. If History information is to be retained, do not clear displayed statistics for any port without first documenting the displayed history information for the associated port. This issue will not be resolved.
CSCef29516
The ALS pulse recovery minimum value is 60 instead of 100. If this occurs, increase the value to 100. This issue will not be resolved.
CSCeb36749
In a Y-Cable configuration, if you remove the client standby RX fiber; a non-service affecting LOS is raised, as expected. However, if you then remove the trunk active RX fiber; a non-service affecting LOS-P is raised, but the previously non-service affecting LOS on the client port is now escalated to a service affecting alarm, in spite of no traffic having been affected. This issue will not be resolved.
CSCee82052
After setting the node time (either manually or via NTP) you must wait for the endpoint of the interval to be reached before the end time will reflect the recently-set node time. Until this has occurred, the date time stamp for the end of the retrieved interval remains 12/31/69. This issue has been closed and will not be resolved.
CSCdx35561
CTC is unable to communicate with an ONS 15454 that is connected via an Ethernet craft port. CTC does, however, communicate over an SDCC link with an ONS 15454 that is Ethernet connected, yielding a slow connection. This situation occurs when multiple ONS 15454s are on a single Ethernet segment and the nodes have different values for any of the following features:
•
•
•
When any of these features are enabled, the proxy ARP service on the node is also disabled. The ONS 15454 proxy ARP service assumes that all nodes are participating in the service.
This situation can also occur immediately after the aforementioned features are enabled. Other hosts on the Ethernet segment (for example, the subnet router) may retain incorrect ARP settings for the ONS 15454s.
To avoid this issue, all nodes on the same Ethernet segment must have the same values for Enable OSPF on the LAN, Enable Firewall, and Craft Access Only. If any of these values have changed recently, it may be necessary to allow connected hosts (such as the subnet router) to expire their ARP entries.
You can avoid waiting for the ARP entries to expire on their own by removing the SDCC links from the affected ONS 15454 nodes. This will disconnect them for the purposes of the proxy ARP service and the nodes should become directly accessible over the Ethernet. Network settings on the nodes can then be provisioned as desired, after which the SDCC can be restored.
This issue will not be resolved.
CSCdy56693
Microsoft Windows XP uses more memory than previous Microsoft operating systems, and this may result in reduced CTC performance. To avoid reduced performance, you can:
•
•
•
•
•
CSCdy62092
When a node connected via SDCC has no Ethernet LAN connectivity, display of SDCC termination alarms is delayed if the fiber connecting a DCC connected node is removed. This issue cannot be resolved.
CSCdy10030
CVs are not positively adjusted after exiting a UAS state. When a transition has been made from counting UAS, at least 10 seconds of non-SES must be counted to exit UAS. When this event occurs, Telcordia GR-253 specifies that CVs that occurred during this time be counted, but they are not. There are no plans to resolve this issue at this time.
CSCdy11012
When the topology host is connected to multiple OSPF areas, but CTC is launched on a node that is connected to fewer areas, the topology host appears in CTC, and all nodes appear in the network view, but some nodes remain disconnected. This can occur when the CTC host does not have routing information to connect to the disconnected nodes. (This can happen, for example, if automatic host detection was used to connect the CTC workstation to the initial node.)
CTC will be able to contact the topology host to learn about all the nodes in all the OSPF areas, but will be unable to contact any nodes that are not in the OSPF areas used by the launch node. Therefore, some nodes will remain disconnected in the CTC network view.
To work around this issue, if no firewall enabled, then the network configuration of the CTC host can be changed to allow CTC to see all nodes in the network. The launch node must be on its own subnet to prevent network partitioning, and craft access must not be enabled. The CTC host must be provisioned with an address on the same subnet as the initial node (but this address must not conflict with any other node in the network), and with the default gateway of the initial node. CTC will now be able to contact all nodes in the network.
If a firewall is enabled on any node in the network, then CTC will be unable to contact nodes outside of the initial OSPF areas. This issue will not be resolved.
NE Defaults
The following caveats apply for NE defaults when managing older, pre-Release 4.5 nodes.

ONS 15454 Conducted Emissions Kit
If you are deploying the Cisco ONS 15454 within a European Union country that requires compliance with the EN300-386-TC requirements for Conducted Emissions, you must obtain and install the Cisco ONS 15454 Conducted Emissions kit (15454-EMEA-KIT) in order to comply with this standard.
CSCdv10824: Netscape Plugins Directory
If you use CTC, JRE, and the Netscape browser with a Microsoft Windows platform, you must ensure that any new installation of Netscape uses the same Netscape directory as the previous installation did, if such an installation existed. If you install Netscape using a different path for the plugins directory, you will need to reinstall JRE so that it can detect the new directory.
"Are you sure" Prompts
Whenever a proposed change occurs, the "Are you sure" dialog box appears to warn the user that the action can change existing provisioning states or can cause traffic disruptions.
Common Control Cards
CSCdw27380
Performing cross connect card switches repeatedly might cause a signal degrade condition on the lines or paths that can trigger switching on these lines or paths. If you must perform repeated cross connect card switches, lock out the corresponding span (path protection, BLSR, or 1+1) first. This issue will not be resolved.
Active Cross Connect (XC10G/XCVT) or TCC2/TCC2P Card Removal
You must perform a lockout in BLSR, path protection, and 1+1 before physically removing an active cross connect (XC10G/XCVT) or TCC2/TCC2P card. The following rules apply.
Active cross connect (XC10G/XCVT) cards should not generally be physically removed. If the active cross connect or TCC2/TCC2P card must be removed, you can first perform an XCVT/XC10G side switch or TCC2/TCC2P reset and then remove the card once it is in standby, or you can perform a lockout on all circuits that originate from the node whose active cross connect or active TCC2/TCC2P will be removed (performing a lockout on all spans will also accomplish the same goal). No lockout is necessary for switches initiated through CTC or through TL1.
Caution
Ethernet Polarity Detection
The TCC2/TCC2P does not support Ethernet polarity detection. The TCC+ and TCCI both support this feature. If your Ethernet connection has the incorrect polarity (this can only occur with cables that have the receive wire pairs flipped), the TCC+/I will work, but the TCC2/TCC2P will not. In this event, a standing condition, "LAN Connection Polarity Reverse Detected" (COND-LAN-POL-REV), will be raised (a notification will appear on the LCD, and there will be an alarm raised). This issue will most likely be seen during an upgrade or initial node deployment. To correct the situation, ensure that your Ethernet cable has the correct mapping of the wire wrap pins. For Ethernet pin mappings, consult the user documentation.
Optical IO Cards
CSCsk03288
The OC48-LR-1550-1 optical card with P/N 87-32-00001 and firmware (bootrom) rev number 76-99-00014-x02a continuously reboots and does not start up during upgrade to a software release 7.20 through 7.23 or 8.0.
Before upgrading to releases 7.20, 7.21, 7.22, 7.23 or 8.0, it is recommended to retrieve the inventory list through CTC or TL1 and check the HW part number field for 87-32-00001 and firmware rev field for 76-99-00014-x02a. If any card matches the HW part number and firmware rev number, replace it with the newer version of the OC48 card such as the OC48AS or MRC card.
This issue will be resolved in Release 8.5.
CSCei26718
On the 15454_MRC-12, when a one way VT/VC circuit on path protection over 1+1 protection is
created, the alarm behavior is not the same as in two way circuit creation. In particular, for the one way circuit creation, UNEQ-V and PLM-V alarms are reported, and the circuit state remains OOS. This issue will not be resolved.
CSCdw66444
When an SDH signal is sent into an ONS 15454 OC-12/STM-4 (IR, 1310 LR and 1550 LR) or an OC-48/STM-16 high-speed (IR and LR) port which has been configured to support SDH, an SD-P (Signal Degrade) alarm will appear as soon as the circuit is created. This alarm will continue to exist until the circuit is deleted.
To avoid this problem, when provisioning an OC-12/STM-4 (IR, 1310 LR and 1550 LR) or an OC-48/STM-16 high-speed (IR and LR) port to support SDH, disable the signal degrade alarm at the path level (SD-P) on the port.
Also, PM data at the path level will not be reliable. You must set associated threshold values to 0 in order to avoid threshold crossing alerts (TCA) on that port. The path threshold values to set to zero are CV-P, ES-P, SES-P, and UAS-P.
These issues are the result of a hardware limitation, and there are no current plans to resolve them.
CSCdw09604
If you are using an XC10G with OC-48, you must use either OC-48AS or OC-48 cards with a revision number higher than 005D.
Electrical IO Cards
CSCse96077
On an IO port false TCAs that indicate line or traffic problems might be raised every 15 min. after the 15 min. pm report. There are no alarms with the associated ports. Traffic is not affected.
In Release 7.2, during a very short period when the defect is present (less than 1 sec.), false TCAs might be raised. This can be reproduced by either removing and then reinserting the card, or by a small burst of defects.
The cards affected are: ONS 15454 DS1, DS1_E1_56, DS3 (including DS3, DS3N, DS3E, DS3NE), DS3_EC1, DS3XM, DWDM, E1, E1_42, OC3-8, OC12-4, MRC-12, OC192XFP; and ONS 15310-CL and ONS 15310-MA IO ports.
There are two work-arounds:
1.
2.
Soft reset might cause a protection switch if any circuit path on the card, or any port on the card or the card itself is in a protection group. Note that the protection switch itself might cause a defect burst, which might introduce false TCAs. Before resetting the card, check if any circuit, port, or card is in a protection group. If there is path protection, BLSR, 1+1 or 1:1/1:N protection on the card, lock the protection using a switch command (for example, LOCKOUT/LOCKON) available to users before you reset the card ensuring that no protection switch occurs during soft reset, and that traffic will not be affected. For a card with no protection type, simply soft reset the card and traffic will not be affected.
This issue will be resolved in a future release.
CSCsc65320 and CSCin92295
In a DS3-EC1-48 1:N protection group for which a path protection circuit drops onto a 1:N protected card, if you remove the card and then reseat it the switch time might exceed 60 ms. This issue will be resolved in a future release.
CSCsc60437
DS3XM one way circuits created with no electrical lines attached to the ports fail to carry traffic. This issue will be resolved in Release 8.0.
CSCei59527
When an XC switch occurs, LOF is driven to the line side. On a DS1-14 this can cause us to see long switch times that are related to hardware issues if the "Treat LOF as a Defect" flag has been set. To avoid this issue, do not set the "Treat LOF as a Defect" flag to true on DS1-14 cards. A future release will remove the "Treat LOF as a Defect" option for this card.
CSCeh43011
An LOS alarm is cleared when switching to protect when the working card is on opposite side of the shelf from the protect card (in portless configuration) in a DS3XM-12 1:N protection group. An electrical port brought into IS state on the portless only card produces an LOS alarm. If you then switch to protect, the alarm appears to clear. To avoid this issue, do not bring electrical ports into IS state on a portless only card. This issue will be resolved in a future release.
CSCdx40300
A transient WKSWPR condition is raised upon deletion of a DS3XM 1:1 protection group. This issue will be resolved in a future release.
CSCec39567
Deleting a DS3I 1:N protection group may leave the protect card LED in a standby state. This can occur in a DS3I 1:N protection group with a LOCKON applied to the working card (ONS 15454 ANSI chassis only). Upon deleting the protection group, the LED on the protect DS3I card and the CTC display are still in the standby state. Soft reset the protect card to update the LED on the card and in CTC. An alternative workaround is to remove the LOCKON before deleting the protection group. This issue will be resolved in a future release.
Data IO Cards
SONET and SDH Card Compatibility
Tables 1, 2, and 3 list the cards that are compatible for the ONS 15454 SONET and ONS 15454 SDH platforms. All other cards are platform specific.
CSCsc11981
Under certain circumstances, E-series cards might learn invalid MAC addresses and temporarily lose well-known/static addresses, possibly resulting in high flood rates. This issue can occur when traffic flows through an E-series card and there are no MAC addresses currently in the MAC table for that E-series card (for instance, after you have cleared the complete MAC table, or when the node is just coming up). The chipset can cause the E-series card to learn invalid addresses in this scenario under high rates of flood traffic (multicast, broadcast, unknown) or PHY interface noise. Side-effects of clearing the MAC table when traffic is flowing can cause the E-series card to lose well-known/static MAC addresses along with dynamically learned MAC addresses. This can cause high flood rates (multicast, broadcast, unknown) possibly reaching the limitation described in the following field notice:
http://www.cisco.com/en/US/ts/fn/620/fn62423.html
This issue can last for a few seconds (typically less). The work-around is to avoid issuing any operation (such as the "Clear all MAC" command) that clears the complete MAC table under heavy traffic loads. To recover from this issue, wait for a few seconds to let the invalid addresses age out, and to allow the software to restore the well-known/static MAC addresses.
CSCdy37198
On Cisco ONS 15454s equipped with XCVT cross-connect cards, neither the E100T-12 nor the E1000-2 cards raise an alarm or condition in CTC when Ethernet traffic is predictably lost due to the following circumstances:
Circuits exist between Ethernet cards (E100T-12 and/or E1000-2) built over Protection Channel Access (PCA) bandwidth on BLSR spans. When BLSR issues a switch, the PCA bandwidth is preempted. Since there is no longer a connection between the ends of the Ethernet circuit, traffic is lost.
Note
This issue will not be resolved.
CSCdr94172
Multicast traffic can cause minimal packet loss on the E1000-2, E100-12, and E100-4 cards. Packet loss due to normal multicast control traffic should be less than 1%. This issue was resolved in Release 2.2.1 for broadcast, and in Release 2.2.2 for OSPF, and some multicast frames. As of Release 3.0.3, the ONS 15454 supports HSRP, CDP, IGMP, PVST, and EIGRP, along with the previously supported broadcast and OSPF.
Note
Note
Note
Multicast MAC addresses used by the control protocols in Table 4 have been added to the static MAC address table to guarantee no loss of unicast traffic during normal usage of these MAC addresses.
E1000-2/E100T
Do not use the repair circuit option with provisioned stitched Ethernet circuits.This issue is under investigation.
Single-card EtherSwitch
Starting with Release 2.2.0, each E100/E1000 card can be configured as a single-card EtherSwitch configuration to allow STS-12c of bandwidth to be dropped at each card. The following scenarios for provisioning are available:
1.
2.
3.
4.
5.
6.
7.
When configuring scenario 3, the STS-6c must be provisioned before either of the STS-3c circuits.
Multicard EtherSwitch
When deleting and recreating Ethernet circuits that have different sizes, you must delete all STS circuits provisioned to the EtherSwitch before you create the new circuit scenario. (See the preceding "Single-card EtherSwitch" section for details on the proper order of circuit creation.) Enable front ports so that the VLANs for the ports are carried by the largest circuit first. A safe approach is to enable the front port before you create any circuits and then retain the front port VLAN assignment afterwards. If you break the rules when creating a circuit, or if you have to delete circuits and recreate them again, delete all circuits and start over with the largest first.
CSCds02031 E1000-2/E100
When you drop two 3c multicard EtherSwitch circuits onto an Ethernet card and delete only the first circuit, you should not provision STS-1 circuits to the card without first deleting the remaining STS-3c circuit. If you attempt to create an STS-1 circuit after deleting the first STS-3c circuit, the STS-1 circuit will not work and no alarms will indicate this condition. Under rare conditions, this could trigger a TCC reset. To avoid a failed STS-1 circuit and other possible problems, delete the second STS-3c prior to creating any STS-1 circuit.
CSCed96068
If an ML-Series card running Software Release 4.6.2 or later is interoperating with an ML-Series card running Software Release 4.6.0 or 4.6.1, then the pos vcat resequence disable command must be added to the configuration of the ML-Series card running R4.6.2 or later. For documentation of this command, consult the Ethernet Card Software Feature and Configuration Guide.
CSCec52443
On an ML-series RPR ring circuit deletion or creation causes an approximately 200 ms traffic loss. To avoid this issue, from the ML-series CLI, perform a "shutdown" on both ends of the circuit prior to circuit changes. This issue will not be resolved.
CSCec52372
You must issue a "shut" command to both ends of a POS circuit before placing the circuit OOS, and issue IS before a "no shut" command. Placing a POS circuit OOS without shutting down can cause long traffic hits. This issue will not be resolved.
CSCec51252
You must issue a "shut" on both ends of affected POS circuits before performing a maintenance action on those circuits. If a POS circuit is restored without first issuing the shut commands, one end of the circuits could come up before the other. During that time, traffic is lost because the other end is not up yet. This issue will not be resolved.
CSCea46580
SPR input counters do not increment on a BVI with an SPR interface. This issue will not be resolved.
CSCea35971
A monitor command may disappear from the configuration after a TCC reboots. To avoid this issue, use the exec command, "terminal monitor," instead (a minor drawback is that this command applies to all VTYs), or, alternatively, reapply the monitor command after connection is lost. This is as designed.

The ML-series cards always forward Dynamic Trunking Protocol (DTP) packets between connected devices. If DTP is enabled on connected devices (which might be the default), DTP might negotiate parameters, such as ISL, that are not supported by the ML-series cards. All packets on a link negotiated to use ISL are always counted as multicast packets by the ML-series card, and STP and CDP packets are bridged between connected devices using ISL without being processed. To avoid this issue, disable DTP and ISL on connected devices. This functionality is as designed.
CSCdz68649
Under certain conditions, the flow-control status may indicate that flow control is functioning, when it is not. Flow-control on the ML-series cards only functions when a port-level policer is configured. A port-level policer is a policer on the default and only class of an input policy-map. Flow-control also only functions to limit the source rate to the configured policer discard rate, it does not prevent packet discards due to output queue congestion.
Therefore, if a port-level policer is not configured, or if output queue congestion is occurring, policing does not function. However, it might still mistakenly display as enabled under these conditions. To avoid this issue, configure a port-level policer and prevent output queue congestion. This issue will not be resolved.
CSCdz69700
Issuing a shutdown/no shutdown command sequence on an ML1000 port clears the counters. This is a normal part of the startup process and there are no plans to change this functionality.
CSCin29274
When configuring the same static route over two or more interfaces, use the following command:
ip route a-prefix a-networkmask a.b.c.d
Where a.b.c.d is the address of the outgoing gateway, or, similarly, use the command:
ip route vrf vrf-name
Do not try to configure this type of static route using only the interface instead of the address of the outgoing gateway. This issue will not be resolved.
CSCin32057
If no BGP session comes up when VRF is configured and all interfaces have VRF enabled ensure that at least one IP interface (without VRF) is configured and add an IP loopback interface on each node. This issue will not be resolved.
CSCdy47284
ML-100 FastEthernet MTU is not enforced. However, frames larger than 9050 bytes may be discarded and cause Rx and Tx errors. This issue will not be resolved.
CSCdz74432
Issuing a "clear IP route *" command can result in high CPU utilization, causing other processes to be delayed in their execution. To avoid this issue do not clear a large number of route table entries at once, or, if you must use the "clear IP route *" command, do not install more than 5000 EIGRP network routes.
DWDM Cards
CSCsd92505
Traffic hits of 100 ms to 300 ms might occur during an OPT-PRE or OPT-BST card software reset or firmware upgrade. This occurs only with cards displaying the vendor ID 1025 in the CTC node level inventory tab when the following conditions are present for the affected card.

This issue is resolved in Release 7.0.1 and all subsequent releases except for Release 7.2.
CSCeh22604
When an MXP_MR_2.5G card is in MIXED or ESCON mode, TCA and alarm optical thresholds of Tx power for laser bias are configurable for ESCON payload, though not supported. This issue will be resolved in the future release.
CSCei19148
When a port is placed in-service while the conditions necessary to squelch the port are present, as in when the trunk port on a DWDM card is OOS,DSBLD and a client port is placed in-service, the client will momentarily enable, emitting light, before squelching due to the trunk OOS,DSBLD condition. The pulse is approximately 500 ms. This issue will not be resolved.
CSCei87554
When using a 1GE payload over the TXP_MR_2.5G the IfInErrors counter does not report oversized, undersized, or CRC errored frames, but rather, reports frame coding only. This issue will not be resolved.
CSCsb47323
For MXP_MR_10DME-C and MXP_MR_10DME-L cards, an unexpected RFI condition might be raised along with an OTUk-BDI. When there is an LOS downstream, the node receives OTUk-BDI. Because of the placement of dual OTN and SONET wrappers, it can also receive an RFI. This issue will not be resolved.
CSCsb79548
A long traffic hit can occur when an active TCC2/TCC2P resets while an MXP_MR_10DME-C or MXP_MR_10DME-L card is rebooting.
This issue can be reproduced as follows:
Step 1
Step 2
Step 3
Step 4
OTUk/ODUk-SD, FEC Uncorrected word alarms are raised on the trunk port. Traffic goes down and does not recover until the MXP_MR_10DME card is able to come up. It is not known when or if this issue will be resolved.
CSCsb94736
After a fault condition (trunk LOS or Y-cable switch) an MXP_MR_10DME card might fail to detect the login message and traffic might not start for some minutes (after multiple login trials). This can occur in an N-F configuration with MDS switch and MXP_MR_10DME distance extension on, where test equipment traffic is set to 2G Fibre channel (FC) full bandwidth occupancy and started. Stop traffic or keep bandwidth occupancy below 80% during the login phase to work around this issue. This issue will not be resolved.
CSCsb95918
All GFP related alarms are raised with their active severities on the standby card after a Y-Cable protection switch. When a DWDM card (with GFP support) in a Y-Cable protection group becomes standby as a result of a Y-Cable protection switch, the GFP alarms raised when the card was active retain their severities instead of assuming standby severities. The alarms can be seen in the alarm pane if not suppressed, or in the condition pane if suppressed. This issue will be resolved in a future release.
CSCsc36494
Manual Y cable switches with squelching turned off can cause a Fibre channel link with brocade switches to go down.
This issue can be reproduced as follows:
Step 1
Step 2
Step 3
Step 4
After a few switchovers, the FC link will go down. SIGLOSS and GFP-CSF alarms are seen on the CTC.
Cisco recommends you provision squelching to be on when interworking with brocade switches. If for some reason, squelching must be off with brocade switches, Cisco recommends you use a FORCE command to perform Y cable switches. It is not known when or if this issue will be resolved.
CSCsc60472
CTC is not able to discover a TL1 OCHCC circuit provisioned over an ITU-T line card (ITU-T OC48/STM16 and ITU-T OC192/STM64). This issue can occur when, using the TL1 client interface, you create the OCHNC layer that will be used by the OCHCC circuit, then create the OCHCC connections that involve the ITU-T line cards. The result is an OCHNC and two OCHCC partial circuits, instead of an OCHNC and a single OCHCC complete circuit. This issue will not be resolved.
CSCsc14290
LOW communication between two nodes equipped with TXP-MR-10E and AIC-I cards does not work with TXP-MR-10E cards in line termination mode, G.709 enabled, GCC present on the trunk port, and LOW circuits created between the transponders and AIC-I; Cisco recommends that you use EOW instead. This issue will be resolved in a future release.
CSCsc58941
Trunk ports of the TXPP_MR_2.5G and MXPP_MR_2.5G can be in facility and terminal loopback at the same time. this can occur if you provision terminal loopback on the protected trunk port after putting the trunk ports in facility loopback. You can clear this condition by removing loopback provisioning on the trunk ports. This issue will be resolved in a future release.
CSCeh94567
Setting a Terminal loopback on an MXP-2.5G-10G trunk port causes OTUK alarms.
This can occur under the following conditions.
1.
2.
3.
4.
This terminal loopback causes OTUK-LOF and OTUK-IA alarms to be reported on both MXP-2.5G-10G trunk ports. This issue will not be resolved.
CSCef15415
RMON TCAs are not raised on the TXPP_MR_2.5G client port after a hardware reset. To see this issue, provision two nodes with TXPP_MR_2.5G (TXP-1 and TXP-2) as follows.

Step 2
Step 3
Step 4
Step 5
Step 6
Step 7

Under very specific conditions the MXPD fails the Telcordia GR-253/G.825 Jitter generation mask test on the 10G transmit trunk port. The 2.5 G transmit client jitter generation remains within mask and does not exhibit this issue.
This only occurs when, in SONET mode, with no FEC, no G,709, and client interfaces looped back, with non-synchronous clocking, and performing the following steps.
Step 1
Step 2
The jitter testbox TX clock recovers from RX with an additional 5 ppm offset added. This issue will not be resolved.
CSCef50726
Receive client fiber removal can cause a switch from the protect to the active in a TXPP_MR_2.5G. To see this issue, perform the following steps.
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
This causes the far end trunk to switch from protect to working span. Similarly, removal of the receive Client fiber at far end causes the near end trunk to switch from the protect to the working span. (Note that the traffic is already lost due to the receive client fiber pull.) To work around this issue, manually switch via CTC from the working to the protect span. This issue will not be resolved.
CSCef13304
Incorrect ALS initiation causes a traffic outage on an FC payload. This issue can be seen by performing the following steps.

ALS is now initiated on TXP-1 port 2 (trunk) and the laser shuts down. Traffic never comes back.
Note
To recover from this situation, perform a manual restart or disable the ALS in this configuration. This issue will not be resolved.
CSCuk51184
When downloading Release 4.7 nodes with Release 4.6 installed, The 15454-32MUX-O and 15454-32DMX-O report an AWG Temperature fail low alarm that subsequently clears. This also occurs when downgrading from Release 4.7 to Release 4.6, where the AWG Temperature alarm fail is high. This issue cannot be resolved.
CSCec22885
AS-MT is not enabled in Port 3 when a loopback is applied. To see this issue, on the TXPP card, make the following 3 changes before clicking Apply:
Step 1
Step 2
Step 3
Now, when you click Apply, CTC issues the error message: "Error applying changes to row2 peer trunk port must not be IS." Port 3 is still IS and the loopback changes are not applied. You must place Port 3 in the OOS-MT state, apply the changes, and then change the loopback to recover.
This error occurs only when all three of the above changes are attempted at the same time.
To avoid this issue, first change both the trunk ports to OOS-MT, click Apply, and then place port 2 in loopback and click Apply again. This issue will not be resolved.
CSCed76821
With Y-cable provisioned for MXP-MR-2.5G cards, if you remove the client receive fiber on one side, the far end takes greater than 100 ms to switch away from the affected card. This issue will not be resolved.

When the FICON bridge does not receive the expected number of idle frames between data packets it will transition to SERV MODE. This issue will not be resolved.
CSCec40684
After a database restore TXPP trunk ports might report SF, resulting in a traffic outage. The SF occurs when you restore the database and then put the port OOS for DWDM cards; then the operating mode in the database is different from the current operating mode. To avoid this issue, either put the DWDM port OOS before restore the database, or, after restoring the database, reset the DWDM cards. This issue will not be resolved.
CSCec51270
Far end traffic does not switch in line termination mode with .G709 off. This can occur with non-revertive Y-cable, and DCC enabled, under certain specific conditions. To avoid this issue, turn on .G709 when in line mode. This issue will not be resolved.
CSCuk42668
TXP-MR-2.5G F1-UDC may not be passed through in a line-terminated configuration with OTN off. This can occur with clean, OC-3/STM-1, line-terminated traffic, with OTN disabled, when you create a D1-D3 tunnel, a D4-D12 tunnel, and an F1-UDC from client to client. This issue will not be resolved.
CSCuk42752
If you go to the Overhead Circuits Tab in network view and select any User Data, F1 or User Data D4-D12 circuit type, no nXP cards are available for selection in the Endpoints. However, user Data type circuits can still be made end-to-end (where "end-to-end" refers to external cards, such as AIC to AIC) if the nXP cards are put in Transparent mode. This issue will not be resolved.
CSCeb49422
With TXPP cards, a traffic loss up to six seconds can occur during a DWDM protection switch. This behavior may be exhibited during protection switches by certain third-party fiber channel switches due to loss of buffer credits resulting in a reconvergence of the fiber channel link. This issue will not be resolved.
CSCeb53044
The 2G Fiber Channel (FC) payload data type in the TXP_MR_2.5G and TXPP_MR_2.5G cards do not support any 8B/10B Payload PM monitoring. This is as designed.
CSCea78210
The TXP_MR_2.5G and TXPP_MR_2.5G cards do not support TX Optical power performance monitoring on the trunk port. This is as designed.
CSCeb32065
Once engaged, ALR will not restart on the trunk lines of a TXP or TXPP card. This occurs whenever ALR engages on the trunk lines of a TXP or TXPP card and the recover pulse width is provisioned to less than 40 seconds. This is a function of the trunk laser turn-on time, and the limiting recovery pulse width will vary by card. To avoid this issue, provision the pulse width to 40 seconds or more. This issue will not be resolved.
CSCuk42588
With ALS mode configured as "Auto Restart" or "Manual Restart," it is possible the ALS Pulse Duration Recovery time can be set to values out of ITU-T recommendation G.664. You can use values out of the range defined in ITU-T recommendation G.664 only in order to interoperate with equipment that lasers cannot turn on or off within the required pulse time. To stay within the specification, you can set this value to 2 seconds and up to 2.25 seconds.
CSCea81219
On the TXPP, the default value for Tx Power High for TCAs & Alarms is too high for the trunk ports. Since Tx Power TCA and Alarm are not supported for trunk ports, this caveat is for informational purposes only.
CSCeb27187
During a Y-Cable protection switch, the client interface sends 200,000 to 300,000 8B/10B errors towards the attached Catalyst 3550 switch. The switch reacts to this large amount of 8B/10B errors by reinitializing the interface and spanning tree. The end result is that a protection switch can lead to a 30-45 second traffic hit if the switch is running spanning tree (default mode). This is expected behavior.
CSCea87290
In a Y-Cable protection group, if GCCs are defined on both cards, both cards' active LEDs will be green. This is by design.
CSCeb12609
For the TXPP, attenuating Port 2 Rx signal, SD, and SF alarms are not declared before LOS-P is raised. This is due to the intrinsic design of the optical interface, which allows required BER performances with dispersion and OSNR penalties.
This can occur when Port 2 is in back to back or has low dispersions and high OSNR.
CSCea68773
The ACTV/STBY LED shows AMBER when a 2.5G transponder is first connected. The DWDM cards introduced a new design: When all the ports are OOS on a card, the card is considered to be in standby mode.
Interoperability
CSCds13769: Fujitsu FLM-150 and Nortel OC-3 Express
You cannot provision the FLM-150 and OC-3 Express in 1+1 revertive switching mode. The problem occurs when the ONS 15454 issues a user request in revertive mode to the protect channel. When the user request is cleared, the ONS 15454 issues a No Request. However, the FLM-150 and OC-3 Express issues a Do Not Revert, which causes traffic to remain on the protection channel. Based on Telcordia GR-253, section 5.3.5.5, the FLM-150 and the OC-3 Express should respond with a No Request.
CSCsl22337
When a DWDM ring or network has to be managed through a Telcordia operations support system (OSS), every node in the network must be set up as multi-shelf. OLA sites and nodes with one shelf must be set up as "multi-shelf stand-alone" to avoid the use of LAN switches.
BLSR Functionality
CSCei67965
A VT traffic hit up to 140 ms can occur when an intermediate node of the VT circuit is isolated. For example, if you have three nodes, A, B, and C, where the circuit is routed from A to C via B, when you isolate Node B, Nodes A and C perform STS-level 100 ms squelching as a part of the VT squelching process. However, the timer resolution on the cross connect card yields 16 2/3 ms accuracy, so the 100 ms timer sometimes (about 80% of the time, depending on the number of VT circuits on a ring) expires approximately 17 ms delayed. This causes VT traffic to be squelched for slightly more than 100 ms. Due to system limitation of timer resolution accuracy and task scheduling delay, there is no further optimization available in the current 15454 BLSR design.
CSCed10127
Extra traffic is not restored when an SF-R occurs on the same span where a lockout of protect is applied at the opposite node, and where the extra traffic is sourced, destined, or travels through the node with the SF-R. to work around this, issue a lockout on each end of the span at the node where the SF-R occurs. Extra traffic should then be restored. This issue will not be resolved.
CSCea59342
DS3 PCA traffic may take up to 20 seconds to recover after a BLSR switch is cleared. This can occur with DS3 PCA traffic on two-Fiber or four-Fiber BLSR configuration with XCVT cards in the same nodes as the DS3 cards. This issue will be resolved in a future release.
CSCdw58950
You must lock out protection BLSR, 1+1, and path protection traffic to avoid long, or double traffic hits before removing an active XCVT or XC10G card. You should also make the active cross connect card standby before removing it.
CSCdv53427
In a two ring, two fiber BLSR configuration (or a two ring BLSR configuration with one two fiber and one four fiber ring) it is possible to provision a circuit that begins on one ring, crosses to a second ring, and returns to the original ring. Such a circuit can have protection vulnerabilities if one of the common nodes is isolated, or if a ring is segmented in such a way that two non-contiguous segments of the circuit on the same ring are each broken.
Database Restore on a BLSR
When restoring the database on a BLSR, follow these steps:
Step 1
Step 2
Step 3
Step 4
Path Protection Functionality
CSCee53579
Traffic hits can occur in an unprotected to path protection topology upgrade in unidirectional routing. If you create an unprotected circuit, then upgrade the unprotected circuit to a path protection circuit using Unprotected to path protection wizard, selecting unidirectional routing in the wizard, the circuit will be upgraded to a path protection circuit. However, during the conversion, traffic hits on the order of 300 ms should be expected. This issue will not be resolved.
Active Cross Connect (XC10G/XCVT) or TCC2/TCC2P Card Removal
As in BLSR and 1+1, you must perform a lockout on path protection before removing an active cross connect or TCC2/TCC2P card. The following rules apply to path protection.
Active cross connect (XC10G/XCVT) cards should not generally be physically removed. If the active cross connect or TCC2/TCC2P card must be removed, you can first perform an XCVT/XC10G side switch or TCC2/TCC2P reset and then remove the card once it is in standby, or you can perform a lockout on all circuits that originate from the node whose active cross connect card or active TCC2/TCC2P will be removed (performing a lockout on all spans will also accomplish the same goal). No lockout is necessary for switches initiated through CTC or through TL1.
Bridge and Roll
CSCsc60635
Bridge and Roll is allowed on the STM1E card, although it is not supported. This issue will be resolved in Release 8.0.
Alarms
CSCsc66474
The ODU-Alarm indication signal is not sent downstream on a client when the line card is provisioned as line terminated. This issue will not be resolved.
CSCse85355
The NE should report alarms or conditions on ingress port not on any internal ports. Alarm detected at the internal ports (TERM) side will be ingress map to the MON side. So the NE raises the STS-MON/VT-MON and STS-TERM/VT-TERM alarms or conditions on the STS-MON/VT-MON ports, irrespective of the actual detection port (MON or TERM). If the user wants the customized severity to be reflected for a specific STS/VT alarms, the alarm profile entities of both STS-MON and STS-TERM, if available, should be changed to the same severity.

TL1
Note
CSCsb72582
You cannot perform an ENT-EQPT for a valid card type when the current equipment state is OOS-AUMA,MEA&UAS. When the fault PPM comes up as OOS-AUMA,MEA&UAS and then the ENT-EQPT command is entered using TL1, the command is rejected. This issue will be resolved in a future release.
CSCsc41650
Using a TL1 script to rapidly preprovision/delete various cards repeatedly in the same slot will reboot the TCC approximately 1 out of 10 times. Put a delay of about 10 seconds between preprovisioning/deletion cycles and the node will not reboot. This issue will be resolved in a future release.
CSCdu53509
When a TL1 session to a remote node (ENE) is established via a gateway node (GNE) and you have changed the node name of the ENE via either TL1, CTC or SNMP, then you must wait for about 30 seconds to issue a TL1 command via the GNE. This delay is to permit the updates to propagate to all nodes in the network. During this transition, neither the old node name nor the new node name can be used in the TL1 session to access the ENE. This 30 second window may be reduced in a future release.
Resolved Caveats for Release 7.2
This section documents caveats resolved in Release 7.2.
Maintenance and Administration
CSCsc62845
When you try delete a provisionable patchcord (PPC) from the CTC Provisioning > PPC tab, sometimes CTC fails to refresh the screen and the PPC deletion appears to have failed. The work-around is to restart into CTC. This issue is resolved in Release 7.2.
CSCsd65791
Authentication fails with "Illegal Registry" error when you try to authenticate from Multi Layer Card to Server using TACACS+. This issue is resolved in this Release.
Hardware
CSCsh17399
OPT-PRE units with FW version 2.0.6, HW version 1.0.0 and Vendor Id 1025 at times don't turn on correctly after first circuit creation. This happens under normal operating conditions. A firmware load to fix this issue has been downloaded on the module. This issue has been fixed in 7.04, 7.22 and 8.0.
SNMP
CSCsc62801
For nodes configured in multi-shelf mode using the default LAN configuration, SNMP traps are not sent to the management system. To avoid this issue, provision any the DCN-connected node as "Socks proxy," then, on such nodes add the following static route:

Common Control Cards
CSCsc68652 TCC2P Continuously Reboots on Upgrade to Secure Mode Node
When you remove a standby TCC2P that is in secure mode locked state and install it in another node, the TCC2P card continuously reboots. This occurs regardless of whether the new node has a working TCC2P card or no TCC2P cards. This can be reproduced by inserting a TCC2P into a non-secure node and then inserting it as the only TCC in a secure node. The card comes up with the front IP address set to 0, which is incorrect. If the card is then rebooted, then it will never come up and will continuously reboot. This issue is resolved in Release 7.2.
Electrical Cards
CSCsd17208
Executing a 1:N switch causes a double traffic hit with a DS3XM12 in a high density backplane. The second hit tends to be less than 1 ms and usually occurs immediately after the initial expected switch. This can occur when running multiple high density chassis, with XCVXCs in a large path protection, and with multiple portless circuits where there are test sets on both ends of the circuits. This issue is resolved in Release 7.2.
DWDM Cards
CSCsc55771
When two MXP_MR_10DME cards are interconnected through OC-192/STM-64 cross connects and traffic is up, if you hard reset one of the MXP_MR_10DME cards, the traffic might fail to recover. To recover traffic flow, place the client port in OOS,DSBLD state, delete the PPM then recreate it, and re-provision the port. This issue is resolved in Release 7.2.
CSCsc56015
Extracting an MSTP card and inserting a different type of card in the same slot will result in an MEA alarm and APC DISABLE condition being raised. The APC DISABLE condition will not clear even if you insert the correct card. The work-around is to send a software reset to the active TCC. This issue is resolved in Release 7.2.
CSCsc62581
A T-TX-PWR-MIN TCA is raised and a wrong receive optical power value (of -40 dB) is displayed after a card is reset. The alert and incorrect Rx value both clear in the next 15 min. sample period. This issue is resolved in Release 7.2.
CSCsc54518
The OPT-BST amplifier card is in a LASER OFF state, even if input power is provided to all input ports. This issue only occurs with Release 7.0 and can be reproduced on a card with the amplifier turned on, in operating conditions (with lasers on) as follows.
Step 1
Step 2
Step 3
Step 4
The amplifier goes into APR for 9 seconds (correct), but after this it turns off; it should go into LASER ON state (State 4 at module level). If this issue occurs, change the card from manual restart to auto restart, then toggle OSRI ON and OFF. This issue is resolved in Release 7.2.
TL1
CSCsc62784
The Calibration Tilt is not properly changed using the TL1 interface. The reference tilt is changed instead. This issue can be seen when you try to change the CALTILT parameter on amplifier cards using the ED-OTS command. To avoid this issue, use CTC. This issue is resolved in Release 7.2.
New Features and Functionality
This section highlights new features and functionality for Release 7.2. For detailed documentation of each of these features, consult the user documentation.
New Hardware
Radio Access Network Support
Note
Release 7.2 adds support for the Cisco Radio Access Network (RAN) Optimization solution with the new Cisco ONS 15454 RAN-SVC card, which implements aggregation node functionality in a RAN.
A typical Radio Access Network (RAN) is composed of Base Transceiver Stations (BTSs) or Node Bs, of Base Station Controllers (BSCs) or Radio Network Controllers (RNCs), and of Mobile Switching Centers (MSCs). The traffic generated by a BTS or Node B is transported to the corresponding BSC or RNC across a network, referred to as the backhaul network. The interface between a BTS and a BSC in Global System for Communication (GSM) and Code Division Multiplex Access (CDMA) systems is called the Abis interface. The interface between a Node B and an RNC in a Universal Mobile Telecommunication System (UMTS) is called the Iub interface.
In RAN Optimization, the Cisco MWR 1941-DC-A router extends IP connectivity to a cell site and a BTS. The router provides bandwidth-efficient IP transport of GSM and UMTS voice and data bearer traffic, as well as maintenance, control, and signaling traffic, over a leased line backhaul network between the BTS and leased line termination and the aggregation node via compression (cRTP/cUDP) and packet multiplexing (PPP mux and Multilink PPP).
In the Cisco ONS 15454, the RAN-SVC card transmits and receives E1/T1 data streams (for Abis) and OC-3 data streams (for UMTS) via the cross-connect cards.
RAN-SVC Card
The RAN-SVC card performs circuit emulation and optimization on traffic from 3rd Generation Partnership Project (3GPP) RAN nodes and provides IP-based backhaul of the optimized traffic to other peer nodes. The RAN-SVC card, when combined with the T1-56 and OC-3 cards, provides a high-rack-density aggregation function for the Cisco RAN optimization solution. When the RAN-SVC is used along with a Cisco MWR-1941-DC-A, it provides transparent RAN aggregation and optimization services.
Optimized traffic is received by the RAN-SVC card from peer cell site routers on VT1.5 circuits via a cross connect card or from native GE ports on the RAN-SVC card. Optimized traffic can also be received on the Cisco ONS 15454 node over the OC-3 through OC-192 range of rate interfaces. The RAN-SVC reconstructs higher-rate data onto VT1.5 circuits and sends it back through the cross connect card. Reconstructed traffic is externally delivered to the 3GPP RAN nodes over DS1 and OC-3 interfaces.
The RAN-SVC card is a multiprocessor card. It consists of three traffic-forwarding CPUs and one service CPU, which performs the control plane function for the card. Each traffic forwarding processor is equipped with one front-side 10/100/1000 Gigabit Ethernet (GE) port, two OC-3 Packet over SONET (POS), two STM-1 backplane interfaces, and 42 T1 backplane interfaces. The service CPU is equipped with a Gigabit Ethernet, one ATM and one POS interface.
In the Cisco ONS 15454, the RAN-SVC card transmits and receives T1 data streams (for GSM applications) and OC-3 data streams (for UMTS applications) via the cross connect cards. For T1 connections (GSM and/or backhaul), up to 126 T1 interfaces from multiple T1-56 cards can be aggregated by the cross connect card to form two STS-1 data streams, which are directed to and terminated on the RAN-SVC card. For OC-3 interfaces (POS and/or ATM), up to eight OC-3 interfaces from multiple OC-3 cards can be aggregated by the cross connect cards to form two STS-4 data streams, which are directed to and terminated on the RAN-SVC card as well.
The RAN-SVC card supports 1:N protection. This allows a single RAN-SVC protect card to protect up to nine working RAN-SVC cards. A RAN-SVC protect card can be installed in any slot and can protect working cards on either side of the shelf.
The RAN-SVC card supports SNMP version 1 and SNMP version 2c. It supports standard ONS MIBS, standard Cisco IOS MIBs, and the CISCO-IP-RAN-BACKHAUL-MIB.
For RAN-SVC slots, connectors, card-level indicators, and port-level indicators consult the user documentation.
New Software Features and Functionality
IEEE 802.17b Based Resilient Packet Ring (RPR)
With Release 7.2 the ML-Series card supports IEEE 802.17b based RPR (RPR). RPR, as described in IEEE 802.17, is a metropolitan area network (MAN) technology supporting data transfer among stations interconnected in a dual-ring configuration. The IEEE 802.17b spatially aware sub-layer amendment adds support for bridging to IEEE 802.17.
RPR is well suited for transporting Ethernet over a SONET/SDH ring topology and enables multiple ML-Series cards to become one functional network segment. RPR overcomes the limitations of earlier schemes, such as IEEE 802.1D Spanning Tree Protocol (STP), IEEE 802.1W Rapid Spanning Tree Protocol (RSTP), and SONET/SDH, when used in this role.
In Release 7.2 and later, the ML-Series card supports IEEE 802.17b based RPR in addition to Cisco proprietary RPR. Some of the advantages of IEEE 802.17b based RPR over Cisco proprietary RPR include:
•

Advantages with SONET/SDH Circuits
The ML-Series cards in an RPR must connect directly or indirectly through point-to-point STS/STM circuits. The point-to-point STS/STM circuits are configured on the ONS node through CTC or TL-1 and are transported over the ONS node's SONET/SDH topology on either protected or unprotected circuits.
On circuits unprotected by the SONET/SDH mechanism, RPR provides resiliency without using the capacity of the redundant protection path that a SONET/SDH protected circuit would require. This frees this capacity for additional traffic. RPR also utilizes the bandwidth of the entire ring and does not block segments like STP or RSTP.
Redundant Interconnect Support
Ring interconnect (RI) is a mechanism to interconnect RPRs for protection from node failure. Protection is accomplished through redundant pairs of back-to-back Gigabit Ethernet connections that bridge RPR networks. One connection is the active node and the other is the standby node. During a failure of the active node, link, or card, the detection of the failure triggers a switchover to the standby node.
RI on the ML-Series Card
RI on the ML-Series card is supported only on Gigabit Ethernet. RI on ML-series is provisioned by identifying peer RPR MACs or station IDs as either primary or standby, and uses an OAM frame to flush the SAS table and MAC table at the add stations. RI on ML-series provides card-level redundancy when connected to a switch running EtherChannel. It also provides protection between individual RPRs, including:

For RPR and RI configuration applications and details consult the user documentation.
Network Circuit Automatic Routing Overridable NE Default
The Network Circuit Automatic Routing Overridable NE default makes it possible to set by default whether or not a user creating circuits can change (override) the automatic circuit routing setting (also provisionable as a default).
The new NE default supporting this feature is:
CTC.circuits.RouteAutomaticallyDefaultOverridable
This default works in combination with the existing circuit routing default:
CTC.circuits.RouteAutomatically
The overridable option enables network administrators to manage how circuits are created on a network-wide basis. For example, if the Automatic Circuit Routing default is set to FALSE (the check box is unchecked by default), then setting the Network Circuit Automatic Routing Overridable default to FALSE ensures that manual circuit routing is enforced for all users creating circuits (the default is not overridable by the user). When the Network Circuit Automatic Routing Overridable default is set to TRUE (the factory configured setting) users can click in the Automatic Routing check box to change the automatic routing setting if they wish.
When the Route Automatically check box is not selectable during circuit creation, the following automatic routing sub-options will also be unavailable:
•
•
•
Like the Automatic Circuit Routing default, the Network Circuit Automatic Routing Overridable default applies to all nodes in the network. The Route Automatically check box is either overridable or not depending on how the default is set for the node you are logged into through CTC. To ensure correct behavior after setting the default, propagate the chosen default setting to all nodes through which users might log into the network to perform provisioning. For more information on NE defaults and their provisioning consult the user documentation.
Fibre Channel and FICON Interface Interoperability Enhancements
Release 7.2 enhanced card mode interoperability features add string (port name) provisioning for each fiber channel and FICON interface on the FC_MR-4 to allow the Cisco Metadata Server (MDS) Fabric Manager to create a link association between a SAN port on a Cisco MDS 9000 switch and the FC_MR-4 SAN port.
Link Management Protocol
Caution
Release 7.2 supports Link Management Protocol (LMP). LMP is used to establish traffic engineering (TE) links between Cisco ONS 15454 nodes or between Cisco ONS 15454 nodes and selected non-Cisco nodes that use vendor-specific hardware.
LMP manages TE links between nodes through the use of control channels. TE links are designed to define the most efficient paths possible for traffic to flow over a network and through the Internet. Traffic engineering encompasses traffic management, capacity management, traffic measurement and modeling, network modeling, and performance analysis. Traffic engineering methods include call routing, connection routing, quality of service (QoS) resource management, routing table management, and capacity management.
LMP manages TE links between peer nodes, such as two optical cross-connect (OXC) nodes. Peer nodes have equivalent signaling and routing. LMP also manages TE links between a node such as an OXC and an adjacent optical line system (OLS) node. An example of an OLS node is an ONS 15454 DWDM node.
Networks with routers, switches, OXC, DWDM optical line systems (OLS), and add-drop multiplexers (ADM) use a common control plane such as Generalized Multiprotocol Label Switching (GMPLS) to provision resources and provide network survivability using protection and restoration techniques. LMP is part of the GMPLS protocol suite.
A single TE link can be formed from several individual links. Management of TE links can be accomplished with in-band messaging, as well as with out-of-band methods. For a pair of nodes that manage TE links, LMP accomplishes the following:
•
•
•
•
•
DWDM networks often use MPLS and GMPLS as common-control planes to control how packets are routed through the network. LMP manages the control channel that must exist between nodes for routing, signaling, and link management. For a control channel to exist, each node must have an IP interface that is reachable from the other node. Together, the IP interfaces form a control channel. The interface for the control messages does not have to be the same interface as the one for the data.
The LMP protocol is specified in an Internet-Draft, draft-ietf-ccamp-lmp-10.txt, which was published as a Proposed Standard, RFC 4204, (http://www.ietf.org/rfc/rfc4204.txt), on 2005-10-28.
For details about LMP network implementation, configuration, applications, troubleshooting, and procedures, consult the user documentation.
