Release Notes for Cisco ONS 15454 SDH
Release 7.2.3


September 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 SDH 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 SDH Procedure Guide; Cisco ONS 15454 SDH Reference Manual; Cisco ONS 15454 SDH Troubleshooting Guide; and Cisco ONS 15454 SDH TL1 Command Guide.

Caveats

Review the notes listed below before deploying the ONS 15454 SDH. Caveats with tracking numbers are known system limitations that are scheduled to be addressed in a subsequent release. Caveats without tracking numbers are provided to point out procedural or situational considerations when deploying the product.

Hardware

CSCsj39710

Send AIS on facility loopback on oc3/stm1(1 port) card is set to False, by default. Workaround is to manually set the parameter to True. This issue will be resolved in a future release.

CSCsj32404

Fan speed is not properly regulated if the Fan Tray is inserted when the CTX is already up and running.

Workaround is change the temperature.

This issue will be resolved in a future release.

CSCsj28603

Unexpected TU-LOP alarm appears on the span card STM64 after creating different types of circuits in DS3I 1:N PG. This alarm does not appear when both the circuits are of the same type (either both one-way or two-way). This issue will be resolved in a future release.

CSCsi63612

Unidirectional DS3 traffic is not happening after upgrading to 7.05. This issue will be resolved in a future release.

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, however, 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 be resolved in a future hardware release.

CSCea78210

The TXP_MR_2.5G and TXPP_MR_2.5G cards do not support TX Optical power performance monitoring on the trunk port. To see this, go to the Optics Performance Monitoring tab of the TXP_MR_2.5G or TXPP_MR_2.5G card, and select the trunk port. TX Optical Pwr is not shown. This is as designed.

CSCdw92634

SDH DS3-I and E3 electrical cards only support a VC4 J1 trace string setting for all VC4s together. You cannot set the J1 byte for individual VC4s. This issue is a limitation of hardware.


Note VC3 J1 strings can be set individually, but the optical cards cannot monitor the VC3 J1 string.


CSCdw14501

Interconnection Equipment failure alarms may be generated at 55 degrees C, and 72 volts. When the operating environment is at 55 degrees C and 72 volts, interconnection equipment failure alarms for the following cards can occur:

STM16SH

STM64LH

STM16LH

The alarms could potentially occur on any of these boards, as well: OC48AS, GigE, OC192 or OC192LR. This issue will not be resolved.

Upgrades

CSCec42769 Database Corruption with ONS 15454 SDH Release 4.0, 4.0.1, 4.1


Caution Before you upgrade to Release 7.x from Release 4.0, 4.0.1, or 4.1, you must read this caveat and run the SDH Circuit Repair Utility (VcCheck) provided on the software CD (also available on CCO).

The XCVXL card on the ONS 15454 SDH allows the intermixing of VC12 and VC3 payloads within a single VC4. When a VC4 contains only one VC12 tributary and at least one VC3 tributary and the VC12 is deleted, the database becomes corrupt.

The database load process on the ONS 15454 SDH occurs during a TCC2/TCC2P reboot, TCC2/TCC2P protection switch, software activation, or database restore. When the database is loaded containing this corruption the load process fails, causing the corrupt database to be deleted from the TCC2/TCC2P flash memory. The previous saved database is then loaded instead. When all saved databases on a TCC2/TCC2P contain the corruption, the TCC2/TCC2P will load with the default provisioning, and all existing provisioning will be lost.

If this issue occurs you will see a loss of either some or all provisioning after a TCC2/TCC2P switch or reset.

To ensure that your network is not vulnerable to this issue, you must first determine if the issue already exists within your network, and if so, correct it. You can detect the issue by using the SDH Circuit Repair Utility (VcCheck) provided on the ONS 15454 SDH Release 4.1.3, 4.6.x, 5.x, 6.x, or 7.x software CDs. The VcCheck tool is also available for download from CCO. Once you have alleviated immediate risk from the issue, you must upgrade to Release 7.x, Release 6.x, Release 5.x, Release 4.6.1, or maintenance Release 4.1.3 (or any later release) to avoid further risk.

The VcCheck utility and its associated README file (in the same directory with the tool) provide details on how to temporarily alleviate this issue before upgrading to a release in which the issue is resolved.

This issue is resolved in Releases 4.6 and later, and in maintenance Releases 4.1.3 and later (caveated herein because of the upgrade issue).

Maintenance and Administration


Caution VxWorks is intended for qualified Cisco personnel only. Customer use of VxWorks is not recommended, nor is it supported by Cisco's Technical Assistance Center. Inappropriate use of VxWorks commands can have a negative and service affecting impact on your network. Please consult the troubleshooting guide for your release and platform for appropriate troubleshooting procedures. To exit without logging in, enter a Control-D (hold down the Control and D keys at the same time) at the Username prompt. To exit after logging in, type "logout" at the VxWorks shell prompt.


Note In releases prior to 4.6 you could independently set proxy server gateway settings; however, with Release 4.6.x and forward, this is no longer the case. To retain the integrity of existing network configurations, settings made in a pre-4.6 release are not changed on an upgrade to Release 7.x. Current settings are displayed in CTC (whether they were inherited from an upgrade, or they were set using the current GUI)


CSCsi74508

A Cisco IOS device may produce the following error when reading or writing the configuration:

Error Message    %DATACORRUPTION-1-DATAINCONSISTENCY: write of 11 bytes to 10 bytes 

No workaround available. This issue will be resolved in a future release.

CSCse83671

In Multiuser configuration, Node Controller (NC) can be changed from Ethernet Switch to Stand Alone with equipped Subtended Shelf Controller (SSC). CTC user is allowed to change the NC from Ethernet Switch mode to Stand Alone. When the NC is up again in Stand Alone mode the SSC shelf is lost. No workaround available. This issue will be resolved in a future release.

CSCsi84335

Tracebacks observed in parseCallerIDString. No workaround available. This issue will be resolved in a future release.

CSCse53347

8.0 SW Activation fails in Multishelf configuration. Activating 8.0 SW release or next releases when previous release is 7.01. Upgrades from 7.01 to 9.0 shall require an intermediate upgrade to 7.04, 7.2, 7.22 or 8.0. Workaround is to extract one of the SSC TCCs and activate. This issue will be resolved in a future release.

CSCse04064

Activate revert with 2 TCC sometimes fails after displaying it succeeded. During SW release Activate/Revert. No workaround available. This issue will be resolved in a future release.

CSCsd91724

MSTP MS SW Activation fails. No internal LAN redundancy and the only Ethernet cable are connected to Standby TCC of subtended shelf.

Workaround:


Step 1 Connect internal LAN redundancy.

Step 2 Switch Active with Stand-By TCC in Node Controller Shelf


This issue is expected to be resolved in future releases.

CSCse90736

SSC connected via MS-ISC is not discovered by NC. After activation from previous Multishelf releases to 7.02

Workaround:


Step 1 Reset the active NC TCC,

Step 2 Reset both MS-ISC,

Step 3 Reset the TCC2s boards,

Step 4 Reset MS-ISC-100 boards.


This issue will be resolved in a future release.

CSCse98553

The cards plugged in the sub shelves are reported as "not present" even if they are plugged and working. MSTP Multishelf NE. This may occur after a reset of the TCCs of the Node Controller (i.e. during SW activate or DB restore)

Workaround: SW reset the Active TCC of the subtended shelves.

This issue will be resolved in a future release.

CSCsf09350

The cards plugged in the sub shelves are reported as "not present" even if they are plugged and working. MSTP Multishelf NE. This may occur after a reset of the TCCs of the Node Controller (i.e. during SW activate or DB restore).

Workaround: SW reset the Active TCC of the subtended shelves. This issue will be resolved in a future release.

CSCsf22525

A link fails while connecting an SSC to NC in a multishelf environment. Changing the node configuration from single shelf to multishelf and assigning the SSC role, the SSC will be able to connect to NC only after 6 minutes. No workaround available. This issue will be resolved in a future release.

CSCse36337

When a Server Trail is created on a 1+1 Protection Group, the Node's database gets deleted, and the Node goes for continuous reboot. No workaround available. This issue will be resolved in Release 7.22, 8.0.

CSCse89357

CTC Network view shows up without any Nodes. The initialization of the network view sometimes would get interrupted with exceptions. Workaround is to relaunch CTC. This issue will be resolved in a future release.

CTC Network view shows up without any Nodes. The initialization of the network view sometimes would get interrupted with exceptions. Workaround is to relaunch CTC. This issue will be resolved in a future release.

CSCse96077

On an IO port with this issue false TCAs that indicate line or traffic problems are 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 or 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 workarounds:

Place the affected ports in OOS-DSBLD and then back to IS. This clears the problem for the specific port on the card, but the traffic will be down during the period of OOS-DSBLD.

Soft reset the card with problem ports. This clears the problem on all ports on the card. 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, 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.

CSCsd92505

Traffic hit from 100mS to 300ms might occur during unit SW reset or firmware upgrade.

The problem is present on OPT-PRE and OPT-BST with the vendorID=1025, visible from the Inventory panel of the CTC.

The problem appears under the following conditions:

OPT-PRE

Control Gain: Always OK

Control Power: Hits below -33dBm

OPT-BST

Control Gain: Might have hits for gain > 17 dB and Pin < -10 dBm (3chs @ ~ -14dBm)

Control Power: N/A

No workaround available. This issue is expected to be resolved in 7.01 and above, except 7.2.

CSCsh21989

Clearing of HP PPJC/NPJC-PDET PM counters is not working. HP PPJC/NPJC-PDET PM counters will not be reinitialized when clear command is executed.


Step 1 Have one STM1_8 card and one any other card.

Step 2 Create a circuit between STM1_8 and other card.

Step 3 Enable PCVC4Mon# to 1 and enable IPPM on STM1_8 card.

Step 4 Check for pdet params in PM, wait for 15 to 20 mins.

Step 5 Do clear params, once this is done pdet params in PM must be reinitialized.


This issue will be resolved in a future release.

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.

CSCsc64015

Rarely, in an STM 1+1 configuration with VC3 traffic from one E3 to another where the source node has a 1:1 protection group, if you perform a parallel upgrade from Release 5.0.2 to 7.0, E3 traffic might incur a 13.2 ms hit. This issue will be resolved in a Release 8.0.

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.

CSCin92246

When one of the underlying connections of a circuit moves to the Unlocked-disabled, failed state, CTC treats the Unlocked-disabled, failed state as out of service and interprets part of the circuit to be out of service, or Locked. However, this is incorrect, as none of the underlying connections is in a Locked state. The result is that the circuit state is displayed as Locked[Partial], even though all of the underlying connections are technically Unlocked. This issue will be resolved in Release 8.0.

CSCin90057

A signal degrade or signal failure is not reported when you inject bit errors into the line for an E3 card. To see the SD or SF, inject a code violation error instead. This issue will not be resolved.

CSCeh92201

When you create a bidirectional MS-SPRing-SNCP IDRI circuit using autorouting and select the PCA option for secondary spans, the circuit is created over working MS-SPRing 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.

CSCef53317

A traffic hit can occur during a clock reference switch. To see this issue, complete the following steps.


Step 1 Set up two ONS 15454 SDH nodes with STM16 SNCP (call the nodes STM16-1 and STM16-2).

Step 2 Set up two ONS 15454 SDH nodes with MXP_MR_2.5G_10G (call the nodes MXP-1 and MXP-2).

Step 3 Place MXP-1 and MXP-2 in Transparent Termination Mode.

Step 4 Ensure that STM16-1 is connected to MXP-1 client 1.

Step 5 Ensure that STM16-2 is connected to MXP-2 client 1.

Step 6 Ensure that MXP-1 trunk is connected to MXP-2 trunk.

Step 7 Connect a traffic generator to MXP_MR_2.5G_10G Port 3 (client) of MXP-1 and feed a PRC clock.

Step 8 Set MXP-1 Clock Reference 1 to MXP_MR_2.5G_10G Port 3, leaving the other two clock references as INTERNAL.

Step 9 Provision circuits such that a combination of VC4-4C, VC12, VC3 and VC4 traffic flows between STM16-1 and STM16-2 through MXP-1 and MXP-2.

Step 10 Gradually inject increasingly negative frequency offset through the traffic generator, in steps of 3 ppm, where you perform the next decrement step only when the node returns to NORMAL state.


When the clock offset reaches around 17 ppm, Clock Reference 1 fails and MXP-1 switches to Clock Reference 2. During the clock switch a traffic hit might occur for less than one second. The same is behavior can occur when injecting positive frequency offset. 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 Reduce the insertion loss of the span just before the amplifier.

Step 2 Execute the APC procedure.


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.

CSCef54670

The SQUELCHED condition is not raised when a non-enhanced MXP card is in MS termination mode. To see this issue perform the following steps.


Step 1 Set up one ONS 15454 SDH node with MXP_2.5G_10G (MXP-1).

Step 2 Provision MXP-1 Port 1 (client) with any payload.

Step 3 Set MXP-1 Port 1 (client) and Port 5 (trunk) to the UNLOCKED state.


LOS and LOS-P alarms are reported on MXP-1 Port 1 (client). The SQUELCHED condition is not reported on MXP-1 Port 1 (client) because AIS is sent out the client port instead. This is as designed.

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 min 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 will not be resolved.

CSCeb39359

When changing NE timing from External or Mixed to Line timing, a Transient IEF alarm might be reported against the standby XC10G. This issue will be resolved in a future hardware release.

CSCdz62367

When replacing a failed working E1-42 card in a 1:1 or 1:N protection configuration with the protect card carrying the switched traffic, bit errors, less than 50ms in duration, are possible on the activated protection card. This issue will not 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. This issue will not be resolved.

CSCdx35561

CTC is unable to communicate with an ONS 15454 SDH that is connected via an Ethernet craft port. CTC does, however, communicate over an SDCC link with an ONS 15454 SDH that is Ethernet connected, yielding a slow connection. This situation occurs when multiple nodes are on a single Ethernet segment and the nodes have different values for any of the following features:

Enable OSPF on the LAN

Enable Firewall

Craft Access Only

When any of these features are enabled, the proxy ARP service on the node is also disabled. The ONS 15454 SDH 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 15454 SDHs.

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 SDH 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.

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.

CSCdy57891

An LOP-P alarm can be inadvertently cleared by an LOS that is raised and cleared. On older STM-N cards, when an LOP condition and an LOS condition are both present on the input, an LOS will be raised. However, upon clearing the LOS with the LOP still present, the LOP alarm is not raised. An AIS-P condition will be visible. This issue will not be resolved.

CSCdw38283

If a node has one good BITS reference and is running in a normal state, and you configure a second BITS reference, then reconfigure the second reference within 30 seconds of applying the first configuration, the node will enter FAST START SYNC mode. To avoid this problem, wait a minute before configuring the second reference a second time. This issue is a hardware limitation, and there are no current plans to resolve it.

CSCdw23208

After creating 509 VLANs and provisioning many Ethernet circuits, Ethernet circuit provisioning can become very slow, or possibly fail. Ethernet traffic may also incur an outage of a few minutes. To avoid this problem, delete any VLANs that are created but not used, and do not recreate them. There is no resolution planned for this issue.

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 and Cross Connect Cards

CSCse32518

TCCs intermittently restart. Noise or communication problem in the TCC to fan tray communication channel that occurs during normal operation causes TCC card to reset. Workaround is to replace fan tray. This issue will be resolved in a future release.

CSCsg40898

SHELF-COMM-FAIL after upgrade to 8.0 and TCC SW reset. Multi-shelf in secure mode from 7.2 to 8.0 releases. Activation is successful. SW reset SSC active TCC. Wait to complete reboot. SW reset NC active TCC. The SSC is lost, SHELF-COMM-FAIL raises. No workaround available. This issue will be resolved in a future release.

CSCsd88118

MSTP MS in secure mode. SSC duplicate alarm and loss of SSC. Connecting any host with the same IP address of the internal shelf subnet (192.168.190.0).

Workaround: Disconnect the host and SW reset of the NC active TCC. This issue will be resolved in a future release.

CSCse02598

Multishelf, MSTP. The FDI/PMI is cleared and the alarms which were suppressed by NLAC are instead raised back as alarms. SW Reset the active TCC of the Node Controller. No workaround available. This issue will be resolved in a future release.

CSCse31217

The Standby TCC continuously reboots. MSTP Multishelf NE. Change any sub shelf to stand alone shelf via LCD.

Workaround: Unplug the standby TCC before changing multishelf role. After the active TCC has come back as stand alone (at least 2 min.) re-plug the second TCC.

This issue is expected to be resolved in future releases.

CSCse77589

SSC connectivity lost after removing the LAN cable from TCC2P LAN port. Remove the LAN cable from LAN port. It is expected SSC to be reachable via routing with TCC on slot 11 (standby). A COMM-SHELF alarm is reported from CTC and the connectivity to the SSC is lost (i.e. all the boards are greyed out). No workaround available. This issue will be resolved in a future release.

CSCsf14879

TCC of Node Controller reloads continuously. Multishelf MSTP NE with several DCC/GCC/OSC provisioned (approximately more than 10) involving cards plugged in subtended shelves. No workaround available. This issue will be resolved in a future release.

CSCsg27342

The Ethernet front port on the TCC has the LEDs turned off (no activity no link). Multishelf MSTP NE after a TCC reload for any reason (i.e. DB restore, SW activate, SW reset).

Workaround: SW reset the TCC suffering the fault. This issue will be resolved in a future release.

CSCsg32221

The subtended shelf is disconnected and a SHELF-COMM-FAIL alarm is correctly reported. Multishelf MSTP NE after a reload of the TCC of the Node Controller for any reason (DB restore, SW activate). No workaround available. This issue will be resolved in a future release.

CSCsb62127

A DCC Link discovered by CTC, can show incorrect bandwidth. When a DCC tunnel is created using two different OC cards, like OC12 and OC48 at its ends, CTC Network view shows incorrect bandwidth. Such a provisioning is a provisioning mistake. No workaround available. This issue will be resolved in a future release.

CSCse53413

Creation of Low Order Server Trails (like VC12 or VT1.5) might reset the active TCC. No workaround available. This issue is expected to be resolved in 7.22, 8.0.

CSCse53413

Creation of Low Order Server Trails (like VC12 or VT1.5) might reset the active TCC. No workaround available. This issue is expected to be resolved in 7.22, 8.0.

CSCec82148

Rarely, traffic hits can occur on TCC2/TCC2P card removal. To avoid this issue, remove the card quickly. To recover from this issue, soft reset the TCC2/TCC2P card. This issue will not be resolved.

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.

Active Cross Connect or TCC2/TCC2P Card Removal

Active cross connect or TCC2/TCC2P cards should not be removed. If the active cross connect or TCC2/TCC2P card must be removed, to minimize network interruption you can first perform an XCVXL side switch 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).


Caution If you mistakenly remove an active cross connect or TCC2/TCC2P card and you subsequently lose traffic on some interface cards, you may need to physically reset these cards if they fail to regain traffic.

Optical IO Cards

CSCee17695 and CSCed26246

Rarely, an STM1-8 card might fail to read MFG EEPROM and will show MEA in CTC. This issue can be reproduced by power cycling the node several times, by quickly removing and reinserting a fuse, or when the fuse is removed for several minutes and then replaced; however, the issue is not likely to be due to the power cycling. If a card enters this state, remove and reseat it, or cycle power again to recover STM1-8 operation. This issue will not be resolved.

CSCdw44431

Cisco ONS 15454 optical cards are not provisioned for particular path labels (C2 bytes). Consequently, they cannot raise a PLM condition. However, the ONS 15454 electrical card that terminates traffic ensures that the C2 byte is correct for the type of traffic carried. If the C2 byte is incorrect, this card raises a PLM condition that is reported against the optical port of ingress. An optical card will not raise a PLM against traffic that passes through a node, though it will appear to raise a PLM against traffic with the wrong C2 byte that is terminated on an electrical card within the node. This issue will not be resolved.


Note Optical cards do ensure that the C2 byte is nonzero (Equipped), and will raise a UNEQ condition if the C2 byte is 0 (Unequipped).


Electrical IO Cards

CSCsh15211

Pump unframed E1 traffic for E1 port whose frame format is E1_MF.LOF will be raised as expected and SF led will be glown.Now change the format to UNFRAMED in CTC.But still the SF led will be glown. Workaround is Soft reset of the card. This issue will be resolved in Release 8.01.

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: DS3i, DWDM, E1, E1_42, STM1-8, STM4-4, MRC-12, STM64XFP

There are two workarounds:

Place the affected ports in locked,disabled and then back to Unlocked. This clears the problem for the specific port on the card, but the traffic will be down during the period of locked,disabled.

Soft reset the card with problem ports. This clears the problem on all ports on the card.

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 SNCP, MSSP, 1+1 LMSP 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.

CSCsd71602

On a four node STM16 SNCP with E1-42 cards set up in a 1:N protection group on a single node, if slots 1, 2, and 4 are designated as working cards, with slot 3 as the protect card, and with circuits provisioned on slot 1 ports, and then you fail the working card on slot 1 and the protect card takes over, and finally you alter the protection group by first removing and then replacing the working card in slot 2, CTC might fail to deny on a subsequent attempt to delete the entire protection group, in spite of the need for the protect card to continue to manage the traffic for the failed card in slot 1. Deletion of the protection group should be denied, because it can result in a loss of traffic. This issue will be resolved in a future release.

CSCeg80233

Long traffic hits can occur on E1-42 when using cross connect FIT cards. This can occur when, on the FIT card, you toggle the 155 mhz clock going to the E1-42 cards to the off position. This issue cannot be resolved.

CSCeg81428

Rarely, a long traffic hit (117 ms) can occur on E1-42 after an XC side switch. In multinode BLSR setups, switching the cross connect cards repeatedly might cause traffic hits greater that 60 ms. To avoid this issue side switch the XC only when needed (and not repeatedly). This issue will not be resolved.

CSCeg19255

Rarely, DS3I VC3 traffic takes a hit greater than 60 ms during a cross connect card soft reset. This issue will not be resolved.

CSCef67059

Bit errors can occur on E1-42 line cards passing traffic, when other E1-42 line cards are initially inserted into adjacent slots. Specifically, inserting line cards into adjacent slots or 1:N protect slots (Slots 3 and 15) can cause hits on Ports 1-14. Also, when the card in the 1:N protection slot is passing traffic, inserting E1-42 line cards into adjacent slots can cause bit errors. The bit errors characteristically last less than 5 ms. After the card is inserted, no further bit errors occur. Ports 15-42 behave differently. No bit errors occur on a line card residing in a non-1:N slot if adjacent line cards are inserted. Bit errors will only occur for these ports if line cards are inserted into the 1:N protection slots (Slots 3 and 15). Bit errors might also occur if traffic passes through the 1:N protected slot, and you insert a line card into any other working slot. A future version of E1-42 hardware will resolve this issue.

Interoperability with SONET DS3i-N-12

When provisioning circuits in SDH to interoperate with SONET DS3i-N-12, you must create a VC4 containing VC3s as a payload in the exact order in which they will attach to port groups on the SONET side.

CSCea52722

With DS3-I cards in a 1:2 protection group, when the protect card is active and in the WTR condition, removing another working card from the protection group clears the WTR condition. To work around this issue, remove the working card from the protection group when the protect card is in the standby state. This issue will be resolved in a future release.

CSCdw80652

When one traffic card in a DS3I 1:N protection group is reset, and then another card is reset, there will be a loss of traffic on the second card, after the first card completes its reset, lasting until the second card completes its reset. This only occurs when the protect card tries to handle the traffic of a card that is resetting, and that card is carrying traffic because when it reset the protect card was carrying traffic for another card. This loss of traffic occurs because the protect card attempts to set its relays to handle the traffic of the working card, but the relays on the working card are also set to carry the traffic, and since the card is resetting, no software is running to switch its relays. This issue most frequently presents itself when testing a double-failure scenario: resetting two cards in a protection group. Wait until the first card completes its reset sequence before resetting the second card to prevent this problem. Configuring cards in 1:1 instead of 1:N protection should also avoid the problem. This issue will not be resolved.

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.

OPT-PRE

WorkingMode is set to Output Power and the Input Com Power value is less than -33dBm.

OPT-BST

WorkingMode is set to Gain with a Gain value of greater than 17 dB, and Input Com Power is less than -10 dBm (three channels at approximately -14 dBm).

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 Set up two MXP_MR_10DME-C or MXP_MR_10DME-L cards, connected back-to-back in two different nodes, A and B.

Step 2 Ensure that Node A has two TCC2 cards; one is active, and the other is standby.

Step 3 Set up any kind of traffic between the two MXP_MR_10DME-C or MXP_MR_10DME-L cards.

Step 4 Soft reset the MXP_MR_10DME card in Node A, then soft reset the active TCC2/TCC2P.


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 Set up MXP_MR_10DME cards so that they are Y cable protected. Squelching is provisioned to be off. Distance extension is turned on.

Step 2 The path between the working pair of Y cable protected cards, has no distance introduced. But the protect path has a delay of 800 km introduced.

Step 3 Start Fibre channel traffic with brocade switches.

Step 4 Perform user-initiated manual Y cable switches from CTC.


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. Two MXP-2.5G-10G cards are connected via the trunk ports.

2. The client ports are connected to respective STM16 line cards.

3. SDCC is enabled on the client ports and the line cards' STM16 port.

4. A terminal loopback is set on the MXP-2.5G-10G trunk port.

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 1 Connect the TXP-1 DWDM-A trunk to the TXP-2 DWDM-A trunk.

Step 2 Connect the TXP-1 DWDM-B trunk to the TXP-2 DWDM-B trunk.

Step 3 Create an external fiber loopback on the TXP-1 client.

Step 4 Connect the TXP-2 client to a traffic generator.

Step 5 Provision 1G FC payload on the TXP-1 and TXP-2.

Step 6 Ensure that traffic is running smoothly.

Step 7 Provision RMON thresholds using TL1 for all TXPP_MR_2.5G ports (client and trunks).

Step 8 Apply a hardware reset to the TXPP_MR_2.5G.


After the card reboots, only DWDM-A and DWDM-B (trunk) port RMON TCAs are raised in the CTC History pane. RMON TCAs for port 1 (client) are not raised. This issue will not be resolved.

CSCef15452

RMON TCAs are not raised when the RMON history is cleared on TXPP_MR_2.5G card. To see this issue, provision two nodes with TXPP_MR_2.5G (TXP-1 and TXP-2) as follows.


Step 1 Connect the TXP-1 DWDM-A trunk to the TXP-2 DWDM-A trunk.

Step 2 Connect the TXP-1 DWDM-B trunk to the TXP-2 DWDM-B trunk.

Step 3 Create an external fiber loopback on the TXP-1 client.

Step 4 Connect the TXP-2 client to a traffic generator.

Step 5 Provision 1G FC payload on the TXP-1 and TXP-2.

Step 6 Ensure that traffic is running smoothly.

Step 7 Provision RMON thresholds using TL1 for all TXPP_MR_2.5G ports (client and trunks).

Step 8 While the traffic is running reset the RMON history by clicking the Clear button in the CTC Payload PM pane.


RMON TCAs are not raised for any port. 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 Set up two nodes with TXPP_MR_2.5G (call the nodes TXP-1 and TXP-2).

Step 2 Ensure that TXP-1 DWDM-A trunk is connected to TXP-2 DWDM-A trunk with a 100 Km span.

Step 3 Ensure that TXP-1 DWDM-B trunk is connected to TXP-2 DWDM-B trunk with a 0 Km span.

Step 4 Ensure that TXP-1 client has an external fiber loopback.

Step 5 Connect the TXP-2 client to a traffic generator.

Step 6 Provision TXP-1 and TXP-2 with FICON 1G payload.

Step 7 Ensure that traffic is running smoothly on the protected span.

Step 8 Remove the receive client fiber at the near end.


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.


Step 1 Set up two nodes with TXPP_MR_2.5G (call these nodes TXP-1 and TXP-2).

Step 2 Connect the TXP-1 DWDM-A trunk to the TXP-2 DWDM-A trunk.

Step 3 Connect the TXP-1 DWDM-B trunk to the TXP-2 DWDM-B trunk.

Step 4 Provision the TXP-1 client with an external fiber loopback.

Step 5 Connect the TXP-2 client to a traffic generator.

Step 6 Ensure that TXP-1 and TXP-2 have 1G FC payload provisioned.

Step 7 Enable ALS on TXP-1 trunk port and set it to "Manual Restart."

Step 8 When traffic is running, remove the receive and transmit fibers on TXP1 port 1 (client). Traffic goes down and shutdown on TXP-1 port 2 (trunk) displays "No."

Step 9 Reconnect the fibers for TXP-1 port 1 (client).


ALS is now initiated on TXP-1 port 2 (trunk) and the laser shuts down. Traffic never comes back.


Note This issue is restricted to the TXPP_MR_2.5G card.


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 to 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 Change Port 2 to OOS-MT from IS.

Step 2 Change Port 3 to OOS-MT from IS.

Step 3 Change Port 2 to facility or terminal loopback.


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.

CSCef44939

Under certain conditions you may be unable to provision an Express Order Wire (EOW) circuit using an MXP_2.5G_10G or TXP_MR_10G card trunk port. This can occurs as follows.


Step 1 Provision an MXP_2.5G_10G or TXP_MR_10G card within a node.

Step 2 Disable OTN.

Step 3 Provision DCC on both client and trunk ports.

Step 4 Go to the Network view Provisioning > Overhead Circuits tab.


During the EOW circuit provisioning only the MXP/TXP client ports are listed for the selection. This issue will not be resolved.

CSCuk51185

After a soft reset of an OSCM or OSC-CSM card, a CONTBUS-IO alarm is raised. This issue will not be resolved.

CSCuk50144

Neither E1 nor E2 circuits are available for EOW circuits on TXP_MR_2.5 TXT in Section and Line Termination mode. This issue will not be resolved.

CSCee45443

When the FICON bridge does not receive the expected number of idle frames between data packets it will transition to SERV MODE. The MXP-MR-2.5G should not be used in scenarios where there is a FICON Bridge in place. 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 does not support any 8B/10B Payload PM monitoring. This is by design.

CSCeb32065

Once engaged, the 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.

CSCeb37346

Near end and far end PMs might increment simultaneously on TXPP-2.5G cards. This can occur when two nodes have TXPP-2.5G cards and two nodes have STM16 cards in a four node network, where both TXPP-2.5G cards have STM16 SFPs on them, and are in MS (Line Termination) mode. By default, the TXPP-2.5G cards are in Splitter protection: the first DWDM port is working and the second is protect. If you remove the receive fiber of the first DWDM port on one TXPP-2.5G card, both near and far end counts begin to increment. The far end counts should not increment in this case. This issue is seen only when the Txpd cards have G709 and FEC on. If the cards have G709 and FEC off, only the near end counts will increment, as expected.

CSCeb26662 and CSCea88023

With TXP-MR-2.5G cards, when the current 1 day Optics PM rolls over, the information is inaccurate. 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.

CSCeb24815

With TXP-MR-2.5G cards, ratios are calculated incorrectly after clearing statistics. This is because after you clear statistics the entire time period becomes invalid. Once the time period rolls over again, values will be reliable for the new period.

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.

Do not use the repair circuit option with provisioned stitched Ethernet circuits. It is not known at this time when or if this issue will be resolved.

Single-card EtherSwitch

Each E100/E1000 card can be configured as a single-card EtherSwitch configuration to allow VC4-4c of bandwidth to be dropped at each card. The following scenarios for provisioning are available:

VC4-4c

VC4-2c, VC4-2c

VC4-2c, VC4, VC4

VC4, VC4, VC4, VC4

When configuring scenario 3, the VC4-2c must be provisioned before either of the VC4 circuits.

Multicard EtherSwitch

When deleting and recreating Ethernet circuits that have different sizes, you must delete all VC4 circuits provisioned to the EtherSwitch before you create the new circuit scenario. (See the preceding "Single-card EtherSwitch" section on page 6 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.

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.

CSCec52443

On an ML-series RPR ring circuit deletion or creation causes an approximately 200 ms traffic loss. Traffic loss is expected to be less than 50 ms for RPR. 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, traffic loss is greater than 50 ms. When a maintenance action is taken, 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.

CSCeb25778

When a MAC-SA is seen for the first time, it is learned, but may age out in less than 5 minutes. If the same MAC-SA is seen again before the first ages out, the entry will age out after 5 minutes, as expected. This issue will not be resolved.

CSCin43669

Timer expiration can cause a system crash when you attempt to remove 250 Shared Packet Ring (SPR) subinterfaces using the "no int spr1" command, while Cisco Discovery Protocol (CDP) is also enabled. To avoid this issue, either turn off CDP, issue the command, and then turn CDP back on; or remove the SPR subinterfaces explicitly. This issue will not be resolved.

CSCea36829

The broadcast packet count is always 0 for the SPR interface. The ML100 and ML1000 hardware does not support counting broadcast packets. This issue will not be resolved.

CSCeb21996

When the POS interface is removed from SPR due to a defect, while SPR is configured in immediate mode, the defect type may not be reported. This only occurs if the defect is set and clears in less then 50 ms.

CSCdz49700

ML-series cards do not appear in the Cisco Discovery Protocol (CDP) adjacencies and do not participate in the Spanning-Tree Protocol. All packets are counted as multicast.

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.

CSCea01675

Packets without an 802.1q VLAN tag are classified as COS 0. This issue will not be resolved.

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 VPN Routing/Forwarding (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.

CSCdy55437

The maximum MAC Address Learn Rate for the ML-Series cards is 1300 MAC addresses per second. This number varies based on the ML-Series control and forwarding plane loads. If the forwarding and control planes are heavily loaded, the maximum MAC Address Learn Rate could be as low as 100 MAC addresses per second. To correct a situation where an ML-Series card has stopped learning MAC addresses, reduce the load on these cards. This load limit is by design.

CSCdy47284

Oversize frames are not supported on ML100 Fast Ethernet ports. Oversize frames cause egress traffic to incur CRC, line, and fragment errors on these ports. To avoid this issue, do not send jumbo packets to ML far end ports. This is as designed.

Alarms

CSCsh24669

IMPROPRMVL alarm on XCVXC-10G becomes critical with timing mode change. Timing mode change from internal to external timing when one matrix card is physically removed with Minor IMPROPRMVL causes the IMPROPRMVL to be promoted to CR. No workaround available. This issue is expected to be resolved in a future release.

CSCsh27567

Absence of DBBACKUP-FAIL alarm. No workaround available. This issue will be resolved in Release 8.01.

CSCsh27580

This appears when the slot is pre-provisioned as 2.5G & put in 10G xc card. No workaround available. This issue will be resolved in Release 8.01.

CSCsg12111

Improper Network Alarm Correlation for LOS-O alarm when LOS-P in not present. The alarm correlation priority of the LOS-O was higher of the PWR-FAIL, hence the Network Level Alarm Correlation performed a wrong correlation. The absence of the LOS-P can be a consequence of a particular test bed configuration (e.g.: differences on optical channels power signals, threshold settings, etc.). This issue will be resolved in a future release.

CSCse95860

CONTBUS-IO-A during SW activation from 7.01 to 8.00 on multi-shelf. The TCC in slot-11 raises a CONTBUS-IO-A alarm that is cleared after that the activation completes. Activation is anyway completed. This issue will be resolved in a future release.

CSCse29610

Missing alarm suppression. In a Multishelf configuration insert a card in a specific slot of the Node Controller, then on the SCC shelf, insert another card in the same slot, then change the administrative state of the card ports belonging to the SSC (e.g.: from IS-AINS to OOS-MT). No workaround available. This issue will be resolved in a future release.

CSCse65998

In Multishelf environment the Alarms get not synchronized after SHELF-COMM-FAIL clears, after disconnection of Sub shelf. Workaround is to reset the sub shelf TCC. This issue will be resolved in a future release.

CSCed28167

When a VC_LOW_PATH_TUNNEL only contains unidirectional circuits, an AU-LOP critical alarm is raised. This can occur when a bidirectional tunnel goes through at least three nodes, and the AU-LOP alarm is shown on the intermediate node on the direction not used. Tunnels are bidirectional. If a tunnel does not have traffic in both directions, it will be alarmed. The alarm will be cleared when a bidirectional circuit is added to the tunnel. This issue will not be resolved.

CSCef63240

Rarely, an LP TIM alarm displays its severity as NR instead of MJ in CTC. This can occur when a VC3 circuit is created on Port 5 and IO has detected a VC4 PLM alarm. This issue will not be resolved.

CSCee29901

A CARLOSS alarm can take up to 3 minutes to be reported depend of the number of VLANs configured on a node. When the alarm does appear, if you clear this major alarm, the severity changes to minor, but then the alarm disappears. The alarm severity behavior will not be changed.

CSCse85355 CSCsd52665 CSCsd56328

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.

MS-SPRing Functionality

CSCdz66275

When creating a MS-SPRing from the network view, the node default values for reversion are not initially used. To see this, starting with no preferences file, log into a node with CTC, and set the node default values for MS-SPRing reversion. Now, in Network view, use the MS-SPRing wizard to create a MS-SPRing. The node level default values are initially ignored while the wizard is still in operation. If you encounter this issue, you may need to change values as appropriate for your network while you are still using the MS-SPRing wizard. Once the wizard is finished, these values are saved to a preferences file and will be used henceforth. This issue will not be resolved.

CSCdw53481

Two MS-SPRings are not allowed to coexist. If you execute a manual ring switch command on one side of an MS-SPRing node and apply another manual ring switch command on other side of the node, the second manual ring switch command is rejected. This works as designed. The implementation complies with Telcordia GR-1230, R6-102.

CSCdx45851

On a four fiber MS-SPRing, restoring the database for all nodes at the same time could cause VC4-16c traffic to fail to switch. Do not restore the database for multiple nodes simultaneously. The proper procedure for restoring the database for multiple nodes is to restore one node at a time. This procedure is documented in the user documentation.

CSCdx19598

A rare hardware failure on an STM16AS card transmitter can trigger SEF on the receiving STM16AS card in a four fiber MS-SPRing (or BLSR) configuration. The BER calculations are suspended when SEF is detected, so SD or SF is never raised. Likewise SEF is not considered a signal failure condition like LOS or LOF, so a protection switch will not occur. If this occurs, use the CTC GUI to force a protection switch on the MS-SPRing (or BLSR). This issue will not be resolved.

CSCdv53427

In a two ring, two fiber MS-SPRing (or BLSR) configuration (or a two ring MS-SPRing or 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. There are two possible workarounds for this issue:

1. Manually route the circuit to avoid the "one circuit over two ring" routing scenario.

2. When routing the circuit automatically, select the Using Required Nodes/Spans option in the Circuit Routing Preference screen, then select the appropriate spans to avoid the "one circuit over two ring" routing scenario.

This issue will be resolved in a future release.

Database Restore on an MS-SPRing

When restoring the database on an MS-SPRing, follow these steps:


Step 1 To isolate the failed node, issue a force switch toward the failure node from the adjacent east and west nodes.

Step 2 If more than one node has failed, restore the database one node at a time.

Step 3 After the TCC2/TCC2P has reset and booted up, ensure that the "MS-SPRing Multi-Node Table update completed" event has occurred for all nodes in the ring.

Step 4 Release the force switch from each node.


SNCP Functionality

CSCee53579

Traffic hits can occur in an unprotected to SNCP topology upgrade in unidirectional routing. If you create an unprotected circuit, then upgrade the unprotected circuit to a SNCP circuit using Unprotected to SNCP wizard, selecting unidirectional routing in the wizard, the circuit will be upgraded to a SNCP circuit. However, during the conversion, traffic hits on the order of 300 ms should be expected. This issue will not be resolved.

CSCeb37707

With a VT SNCP circuit, if you inject signals with a thru-mode test set into one path of the circuit in a particular order, you may not see the appropriate alarms. This can occur when you first inject LOP-P, then clear, then inject LOP-V. This issue will not be resolved.

Active XCVXL or TCC2/TCC2P Card Removal

As in MS-SPRing, you must perform a lockout on SNCP before removing an active cross connect or TCC2/TCC2P card. The following rules apply to SNCP.

Active XCVXL cards should not generally be physically removed. If the active cross connect or TCC2/TCC2P card must be removed, you can first perform an XCVXL 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.

Performance Monitoring

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.

SNMP

SNMP Attribute Changes

The following SNMP attributes will be replaced in future releases, and will no longer be supported after Release 7.x.

cMsDwdmIfMultiplexSectionRingDirection

Resolved Caveats for Release 7.2.x

Maintenance and Administration

CSCsj26546

606196361 exception appears on the performance monitor tab on the CTC card. No data appears on the tab.

This issue has been resolved in Release 7.23.

CSCsi89104

Duplicate warning messages appear when compiling the V2 MIB files.

This issue has been resolved in Release 7.23.

CSCsi78162

A router that has the SNASwitch feature enabled may generate several of the following messages along with tracebacks:

%DATACORRUPTION-1-DATAINCONSISTENCY: copy of xx bytes should be xx bytes

This issue has been resolved in Release 7.23.

CSCsj05789

Under CTC network view, you can create a new domain and add nodes to that domain. These nodes will be listed inside the new domain. Delete the added node from the domain and remove the domain itself. Again add the previously deleted node. You can observe that the node appears along with the removed domain.

This issue has been resolved in Release 7.23.

CSCsf19530

Fan tray array board exceeds 60dbA acoustic noise limit. This issue has been resolved in Releases 7.04 and 7.22.

CSCsg51928

Circuits do not go in service. APC regulation doesn't work.

1 - release 5.xx create DCC without set ringId

2 - update any node in network to 7.xx release

3a - add new node in network starting from 7.xx release

3b - after point 2 delete and recreate DCC on one node .

Workaround: After update to 7.xx, you can delete and recreate DCC termination on all nodes in network.

This issue is resolved in 7.04, 7.22 releases.

CSCsg52340

Automatic Routing of circuits using CTC 7.2 or higher, on nodes older than 7.2 is not possible. A new NE Default introduced in 7.2, causes this problem. Workaround is to toggle the CIRCUITS_AUTO_ROUTE_DEFAULT_OVERRIDABLE NE Default. This issue is resolved in Release 7.22, 8.0.

CSCsd53751

Unable to provision the AREA ID with circuits routed. When there is an active circuit between the nodes, CTC and TL1deny provisioning of an OSPF Area ID. TL1 rejects the command with a proper error message, but CTC needs modification to make the error message appropriate.

This issue has been resolved in Release 7.22.

CSCse92125

Attempt to log-in using CTC. CTC login fails. Workaround is to ensure that the PC is not running a Turkish locale. This issue is fixed in Release 8.0.

CSCse99104

CTC can incur either repeated failures when you attempt to log in to an NE, and/or a very long time to discover all ENEs behind a GNE (could be over 30 minutes on a medium sized network). This issue affects all ONS 15xxx releases from R4.1 to 7.2. This condition is more likely to happen on Windows XP after an upgrade to Service Pack 2, and when the network is made of a medium to large number of GNEs/ENEs with SOCKS enabled. This condition can also happen in the case of networks with poor connectivity between CTC and the GNEs.

The solution involves an enhancement to the SOCKS discovery protocol by introducing the concept of designated SOCKS servers. A designated SOCKS server is a NE that runs SOCKS, is LAN connected and has been explicitly marked as a potential SOCKS server by the user. CTC allows the user to enter an unlimited number of designated SOCKS servers. When designated SOCKS servers are defined, the automatic SOCKS server discovery protocol is disabled, resulting in substantial performance improvement during CTC login and ENE discovery.

CSCse53017

Circuit creation when attempted on ML cards between a 7.2 NE and an older NE, the wizard would die. The source should be on 7.2 NE and destination on the older NE. Workaround is to interchange the source and destination. This issue is resolved in Release 7.22, 8.0.

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 workaround is to restart into CTC. This issue is resolved in a Release 7.2.

CSCsi04127

When you upgrade nodes from R6.22 to R7.0.4, BITS-1 IN, BITS-2 IN, BITS-1 OUT, and BITS-2 OUT go into In-Service (IS), although the R6.2.2 line-timed nodes have all the BITS facilities set to Out-Of-Service (OOS), before the upgrade. This issue is resolved in Release 7.05 and 7.23.

CSCsj04557

Users can now control the local/global domain flag through CTC preference. Previously, the user controlled the local/global flag setting from the login node Network Element (NE) default (CTC.network.LocalDomainCreationAndViewing). Any flag changes would be applied immediately in the CTC session.

To change the flag in Release 7.23, from Node view or Network view, open the "Edit" menu and select "Preferences." In the Preferences dialog, click the checkbox labeled "Domain Settings." You must restart CTC after changing the flag.

CSCsh77496

If Path Protection/SNCP circuits are created while path defects are present on Path Protection/SNCP trunks, then sometimes Path Protection/SNCP circuits may not switch and traffic outage is observed

Workaround: Avoid creating Path Protection circuits while faults are present on either of the
Path Protection trunks ports. This issue is resolved in 6.03, 7.05 and 7.2.3

Hardware

CSCsd91472

FTA Failure causes TCC resets. FTA Failure. Workaround is to replace FTA

CSCsi29405

Some fan trays exhibit electrical noise problem that causes communication failure between the fan tray and the controller card. Eventually, this causes the controller card to reboot. The amount of noise in the system is directly proportional to the Voltage level of the shelf and inversely proportional to the speed of the fans.

Workaround: When this situation occurs allow the fan trays to run at high speeds. There is considerable reduction in the noise. This is not configurable on the node. This issue is resolved in Release 6.0.3, 7.0.5, 7.2.3.

DWDM Cards

CSCsg00777

FC traffic corrupted on MXP-MR-10DME

Following pattern is received from client I/F starting from byte #3 of FC word:

D21.5, D21.3, D21.3 = xx B5 75 75

D21.5, D21.4, D21.4 = xx B5 95 95

D21.5, D21.7, D21.7 = xx B5 F5 F5

D21.5, D21.6, D21.6 = xx B5 D5 D5

D10.5, D21.4, D21.4 = xx AA 95 95

D10.5, D21.6, D21.6 = xx AA D5 D5

Traffic is corrupted only if a mix of above sequence is repeated five times. No workaround available. This issue was resolved in Release 7.03.

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 workaround is to send a software reset to the active TCC. This issue is resolved in Release 7.2.

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 reprovision the port. 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 7.0.1 and 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 From the card-level Maintenance tab set ALS Mode to Manual Restart and click Apply.

Step 2 Set OSRI to ON and click Apply. The amplifier turns off.

Step 3 Set OSRI to OFF and click Apply. The amplifier stays turned off (this is expected, since in Manual Restart the lasers are turned back on by means of a Request Laser Restart command issued in CTC).

Step 4 Select the Request Laser Restart check box in the Maintenance tab and click Apply.


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.

Data IO Cards

CSCsf16347

The rpr-ieee0 interface comes up without a single circuit provisioned. This happens when the first bridge-group is configured on the rpr-ieee0 interface (on a sub-interface of rpr-ieee0). Also, when the last bridge-group on the rpr-ieee0 interface is deleted. There is no workaround once the problem appears. This issue is resolved in Release 7.22. The fix will also be present in release 8.0.

CSCsf24408

Customer traffic affected. On an open 802.17 RPR ring, one far ML had circuit only on EAST SPAN. But "show rpr protection" showed that both the SPANs Were IDLE. The other far ML showed its WEST SPAN with SF.

Workaround: Reload the far ML showing incorrectly the IDLE on both WEST and EAST sides.

CSCsg36810

If a card is configured and reloaded with forced-switch request on both spans (east and west), upon reload the card crashes again. This cycle keeps repeating.

Workaround: Configure force-request only for one span (either east or west) before reloading.

This issue is resolved in Release 7.22

CSCsg39242

RI switchover from active to standby is not happening when foreign mode is configured. RI switchover is working when foreign mode is not configured. No workaround available. This issue is resolved in Release 7.22.

CSCsb43596

ML100T cards send out approximately 5% of frames with a bad CRC. This occurs in the following scenario:

Autonegotiation is disabled and the speed is set to 100/ Duplex to Full.

ML startup configuration is saved on TCC and the ports are enabled.

Card is rebooted.

Some ports display CRC errors that are not always consistent. Additionally, after a reboot, some ports display CRC errors. This issue is resolved in Release 7.23.

Optical IO Cards

CSCsg75100

SEFS-S PM Parameter do not increment and also no TCAs reported. On injection of A1A2 frame errors, SEFS-S is not incrementing. No workaround available. This issue is resolved in Release 7.04 and 7.22.

Common Control Cards

CSCsi79020

Large memory leak has been observed on TSCs after upgrading to 7.22 software.

This issue has been resolved in Release 7.23. No memory leak observed after upgrading to 7.23.

CSCsg05534

When the 10 Mhz clock fails on the ACT TCC the node loses traffic for the entire time that the clock is failed OR the TCC remains active. The TCC does not switch for 90 secs even though the detection of the failure triggers a processor reset. This issue is fixed in 7.22

CSCsg43952

In CTC, Shelf view, select Provisioning -> General -> General and configure: - 10/20/2006 as Date - 16:05:00 as Time - "(GMT+01:00) Amsterdam, Berlin, Rome, Stockholm, Paris" as Time Zone - Use Daylight Saving Time checked The Network Element is configured on the right time. Now change the Time Zone to "(GMT+00:00) Dublin, Edinburgh, London, Lisbon": the Network Element time changes from 16:05 to 14:05 this t is wrong because in London it's 15:05. This issue is resolved in 7.22

CSCsf25767

When trying to unlock the CTC sessions after a timeout for inactivity. The customer cannot use all special characters in their passwords when using the Radius feature of 6.2 on 15454 nodes. Workaround is to ensure not to allow the CTC sessions to lock out. This issue is resolved in 7.22 and 7.04.

CSCse01108

When the NE time is changed from CTC (or TL1), the pm bins of the interfaces (OCn/Ds1 on ctx-cl and OCn on 310-MA), which are on the active tcc, does n't get marked as partial. No workaround available. This issue is resolved in Release 7.22 and 8.0.

CSCse29736

Active TCC resets on the node controller when you delete a failed sub shelf controller. Workaround is to delete the sub shelf controller before disconnect it from the VLAN. This issue is resolved in 7.02 and 8.0.

CSCse98996

The issue can be reproduced as follow:


Step 1 On the node Infy12 went to Network view, Edit--->Preferences---->Checked Display events

with Node Time Zone

Step 2 Changed the time to 11-Mar-2007 01:59:00 PST and let it pass the 02:00:00 am.

Step 3 CTC Node view-->Provisioning-->General Tab correctly showed the changed time as 03:00:00 PDT.

Step 4 Generated a LOS on a OC3 card. CTC Alarm pane showed the new PDT time.

Step 5 Retrieved audit trail. Audit trail showed the correct PDT time.


The problem is not observed on this load.

CSCse60231

OSPF-HELLO alarms will be raised on DCCs when upgrading nodes to Release 6.x or later if the network contains a node running any release prior to Release 4.0. Although networks containing mixed Release 3.x and 6.x nodes are not supported, such a mix might occur briefly as nodes are upgraded. The OSPF-HELLO alarms indicate that there is no management communication along the affected DCC. If the DCC was used for management communication prior to the upgrade, some nodes might become isolated. To avoid this issue ensure that all nodes are first upgraded to Release 4.0 or later before upgrading any node to Release 6.0 or later. This issue is resolved in maintenance Release 6.2.2.

CSCse44516

Reboot of Active TCC will cause the Standby TCC to reset and the DB will throw away. All provisioning will be lost. The problem is reproduced when a node that has at least two server Trails on it, has one server trail with its source on that node and another server trail that has its destination on that node. When the node is rebooted or a new software load is activated on that node, the DB will be thrown away and all provisioning lost.

Workaround: Provision Server trails on a node such that the node is either the source of the Server Trails or the destination of the Server Trails. The node cannot have both. This issue has been resolved in 7.02 and 8.0.

SNMP

CSCsf97897

SNMP walk on the media independent table will fail but the individual get requests will succeed.

Workaround: Specific requests (i.e., the mediaIndependentIndex must be specified) will work.

This issue is resolved in Release 7.04, 7.22 and 8.0.

CSCsc62801

For nodes configured in multishelf 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:

Destination: 0.0.0.0

Next hop: DCN Router

Cost: 10

Provision any non-DCN connected node as ENE.

A white paper/application note is in progress and can be requested from Cisco TAC. A documented solution is available in the ONS 15454 DWDM Procedures Guide.

TL1

CSCsh04184

When a cross connect/circuit is created through CTC with E-Series card as one end, the output of the command RTRV-CRS: SLOT-ALL: a; from TL1 does not contain the E-Series end's AID. This bug is found in 7.0. It has been fixed in 7.0.4, 7.2.2, 8.0, 8.0.1

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.

CSCsi68800

TL-1 sessions cause memory leaks. This issue has been resolved in Release 7.23.

Alarms

CSCeh65469

Intermittent CONT-BUS-IO alarm on Opt.PreAMp after an upgrade. Customers performing software upgrades on MSTP DWDM platform began receiving intermittent CONTBUS-IO-B alarms to the Optical PreAmp located in slot 2 and slot 17. It always seems to happen when slot 11 is the active TCC2. Workaround is to switch the TCC2 card. This issue has been resolved in 5.05, 6.0, 7.0, 7.22 and 8.0 releases.

CSCsd86091

In Multishelf the EQPT alarms on Subtended Shelf are not cleared by SHELF-COMM-FAIL

When SSC is not connected to NC and in the meanwhile there is an EQPT alarm.

Workaround: SW reset of NC TCC. This issue is resolved in Release 7.02.

CSCse25589

In a mutlishelf configuration, a non existing IMPROPER REMOVAL ALARM is raised when resetting a TCC on the node controller. Cause a real IMPROPER REMOVAL ALARM on a subtended shelf, extracting a card. Then Delete the extracted card from CTC. After that, reset the TCC on the node controller. The alignment of the alarms with the new active TCC makes the IMPROPER REMOVAL ALARM be raised again on the subtended shelf. Workaround is to reset both the TCC of the subtended shelf.

BLSR Functionality

CSCsg99236

The issue can be reproduced as follows:


Step 1 Create BLSR setup such that OC192-XFP cards are present in slots 12 and 13.

Step 2 Initially create 2F BLSR.

Step 3 Create 96 STS1 circuits between two different OC48 AS cards.

Step 4 Check for switching (Manual, Forced, Fiber pull etc.) of circuits going on STS1, STS48, STS49, STS96 on the span card.

Step 5 All the switches were within 20 ms.

Step 6 Check the same in 4F BLSR setup as well.


For 4F checked for circuit going on STS1, STS48, STS192, and STS145.

The problem is not observed. Hence, the issue is resolved.

Interoperability

CSCse40661

Variables not visible to the user are uninitialized. The variables are not used so there is no bad behavior observed. However, these variables interfere with our ability to debug ospf-related issues. These variables are uninitialized on non-OSC links. The variables are isOptLinkEast and optRingID. They take on random values for non-OSC links. No workaround available. There is no visible or adverse effect to this issue. This issue is resolved in Release 6.2.2.

New Features and Functionality

This section highlights new features and functionality for Releases 7.0.x. For detailed documentation of each of these features, consult the user documentation.

New Hardware

Radio Access Network Support


Note Release 7.2 software and TL1 documentation support the RAN-SVC card; however, the card itself is not yet available. Additional documentation for this card type, as well as an update to the release notes, will become available when the card is released in the future.


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 (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 sublayer 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:

Steering. Ring protection is accomplished through steering instead of wrapping. Steering is a more efficient way of routing around a failure.

Dual-transit queues. Dual-transit queues offer more control in handling transit traffic.

Best-effort traffic classifications. "Best Effort" and "EIR" traffic classifications improve distribution of traffic across a best-effort service class.

Interoperability. Conformance to the IEEE 802.17b standard increases interoperability with third-party vendors.

Built-in service provider support. RPR provides built-in operations, administration, and maintenance (OAM) support for service provider environments.

The following IEEE 802.17b based Resilient packet ring (RPR) features are supported for ML-series cards.

Multiple data path features are supported:

Bridging is supported, as specified in the IEEE 802.17b spatially aware sublayer amendment.

Shortest path forwarding through topology discovery is supported.

Addressing. unicast, multicast, and simple broadcast data transfers are supported.

Bi-directional multicast frames flood around the ring using both east and west ringlets.

The time to live (TTL) of the multicast frames is set to the equidistant span in a closed ring and the failed span in an open ring.

Multiple service qualities are supported:

Per-service-quality flow-control protocols regulate traffic introduced by clients.

Class A allocated or guaranteed bandwidth has low circumference-independent jitter.

Class B allocated or guaranteed bandwidth has bounded circumference-dependent jitter. This class allows for transmissions of excess information rate (EIR) bandwidths (with class C properties).

Class C provides best-effort services.

Efficient design strategies increase effective bandwidths beyond those of a broadcast ring:

Clockwise and counterclockwise transmissions can be concurrent.

Bandwidths can be reallocated on non-overlapping segments.

Bandwidth reclamation. Unused bandwidths can be reclaimed by opportunistic services.

Spatial bandwidth reuse. Opportunistic bandwidths are reused on non-overlapping segments.

Temporal bandwidth reuse. Unused opportunistic bandwidth can be consumed by others.

Fairness features ensures proper partitioning of opportunistic traffic:

Weighted fairness allows a weighted fair access to available ring capacity.

Aggressive fairness is supported.

Single Choke Fairness Supports generation, termination and processing of Single Choke Fairness frames on both spans.

Plug-and-play automatic topology discovery and advertisement of station capabilities allow systems to become operational without manual intervention.

Multiple features support robust frame transmissions:

Service restoration time is less than 50 milliseconds after a station or link failure.

Queue and shaper specifications avoid frame loss in normal operation.

Fully distributed control architecture eliminates single points of failure.

Operations, administration, and maintenance support service provider environments.

The following IEEE 802.17b based RPR features are not supported on the ML-series cards.

EoMPLS

IP forwarding

Wrapping, the optional IEEE 802.17b protection scheme (Steering, the protection scheme mandated by the standard, is supported)

Layer 3 routing

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:

Two RPRs

Two Cisco proprietary RPRs

A Cisco proprietary ring and an 802.17 ring

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:

Using Required Nodes/Spans

Review Route Before Creation

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 LMP is a leading edge feature, requiring specific equipment and network topology to function successfully. Contact Cisco Optical Product Line Marketing for an initial network needs evaluation and specific recommendations before deploying the LMP feature.

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:

Maintains control channel connectivity

Verifies the physical connectivity of the data links

Correlates the link property information

Suppresses downstream alarms

Localizes link failures for protection/restoration purposes in multiple types of networks

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.

CTC Cache Installer

The purpose of this cache installer is to allow installing/reinstalling/upgrading CTC core jars into the user's CTC jar cache. The executable: SetupCtc-MMmm00.exe - a self-extracting .zip file - is for this purpose (where MM is the major release and mm is the minor release). To use it, the user runs the SetupCtc .exe. This produces a directory that consists of the CTC core jars and LDCACHE.exe. The user can then, from that installed directory, 'double-click' on LDCACHE.exe to get the CTC core run-time jars copied into the CTC jar cache. LDCACHE.exe can be run at a later time as well to recopy the CTC core jars into the user's CTC jar cache.
