Release Notes for Cisco ONS 15454 SDH
Release 8.0
May, 2008
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 8.0" version of the Cisco ONS 15454 DWDM Installation and Operations Guide; and the "Release 8.0" 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 and Cisco ONS 15600 SDH TL1 Command Guide.

Changes to the Release Notes
This section documents supplemental changes that have been added to the Release Notes for Cisco ONS 15454 SDH Release 8.0 since the production of the Cisco ONS 15454 SDH System Software CD for Release 8.0.
The following changes have been added to the release notes for Release 8.0.
Added the issue of RTRV-FAC TL1 command showing the payload as FSTE instead of GIGE on the ML1000-2 card in the resolved caveats section.
Changes to Caveats
The following caveat has been added to the release notes:
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
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
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:
•
•
•
The alarms could potentially occur on any of these boards, as well: OC48AS, GigE, OC192 or OC192LR. This issue will not be resolved.
CSCse67377
AIS-L Alarm is not visible against EC1 port, if LOS or LOF is injected onto the port. EC1 port is in service and there is no circuit present. This is a hardware limitation which detects AIS-L received from line side, but it cannot raise AIS-L when it receives LOS or LOF from the line.
CSCsi78715
When loss of signal (LOS) occurs on the client side of MXP-MR-2.5G card, the Y-cable protection switch does not occur and drops the traffic. The MXP-MR-2.5G will not report generic framing procedure (GFP) alarms such as client signal fail (CSF) and in case of fiber channel client, the link recovery counter will not be incremented correctly.
Workaround is to manually switch the traffic away from the client experiencing LOS . This will be fixed in a future release.
Upgrades
CSCec42769 Database Corruption with ONS 15454 SDH Release 4.0, 4.0.1, 4.1
Caution
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
Note
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.
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
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
Step 9
Step 10
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
Step 2
The APC procedure does not check consistency between the gain set point and the real gain, but rather only verifies the amplifier total output power. As a workaround, manual setting can be performed to align these values, although the discrepancy does not impact the normal functioning of the amplifier. This issue will not be resolved.
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
Step 2
Step 3
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:
•
•
•
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
Table 1 summarizes B1, B2, and B3 error count reporting for SDH optical cards. Note that not all reporting is done according to ITU specifications. In particular, ITU specifies error counts for B1 and B3 as the number of blocks with errors (refer to ITU-T G.826 for paths and ITU-T G.829 for RS and MS).
CSCdw82689
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 plug-ins directory, you will need to reinstall JRE so that it can detect the new directory.
CSCsh02230
If IOS CLI is used to configure Timezone and DST rule configuration then the output shown in the show running config command and show clock detail differ from what was configured. To avoid this issue it is recommended to use CTC provisioning tab to configure clock related provisioning.
CSCse04103
Applying the forced switch/manual switch on protect facility when no protection switch in operation, FRCDWKSWBK-NO-TRFSW/MANWKSWBK-NO-TRFSW is not raised for 1+1. There is no workaround for this issue.
CSCse87943
RFI-P is raised on both Working and Protect path in a 1+1 topology on an ONS 15310-MA. This occurs with an ML card with an STS cross connection with another ML card in another chassis and when the POS port on the 15310 MA side is shut down. There is no workaround for this issue.
CSCse38590
In the RPR topology, one station reports a "remote WTR" on a space, even though the neighboring station is not advertizing WTR. This issue is observed after many XC pulls/switches, deleting and recreating circuits, and replacing cross connects completely. This issue does not appear to have any real impact to traffic, but can potentially complicate troubleshooting. This problem was seen after multiple XC-pulls, XC-side-switches, circuit-deletions and circuit-creations. The workaround is to configure a forced-switch on both ends of the problem span, and then remove the forced-switch from both ends.
CSCsd44081
A series of crashes and reboots may occur when a policy-map includes approximately 200 class-map entries and policers. This error appears to occur when the card is boots up, the FPGA process is attempting to download the new FPGA, the policy-map has at least 200 class-map entries, and traffic has been punted to the host. These conditions may trigger a provisioning-message timeout on the ML card that can lead to a crash. Since the system boots up in the same state, a continuous series of crashed and reboots may occur. A workaround is to remove the circuits and wait until the node boots up with the latest FPGA image before reconfiguring the circuits.
CSCse23518
The RPR SPAN-MISMATCH alarm is not reported correctly in some situations. After creating and deleting an East-to-East RPR circuit through TL-1 x-connects and creating a West-to-West RPR circuit through the TL-1 x-connects script, both within less than on second of the other, the RPR-SPAN-MISMATCH alarm is seen only on one side of the circuit and not on the other side. This problem does not occur when the operations are made manually. This alarm indicates mis-cabling or cross-connects created between two East spans or two West spans. A workaround is to ensure more than one second between the deletion of one circuit and creation of the another.
CSCse75851
Tracebacks are seen in "show tech" or "show ons alarm defect" output for ML100T-8 on the 310CL after logging in through the CTC by way of the IOS CLI. This issue does not occur when these commands are issued through the console. The workaround is to ignore these tracebacks because they do not impact the functioning of the data card.
CSCse90514
The soak timer on POS port reduces which is not an expected behavior after creating a circuit on a POS port that is kept in OOS state. There is no workaround.
CSCse58432
Upgraded splitter OCHCC has OCHTRAILs shown as OOS[PARTIAL]. When upgrading a splitter-protected OCHCC 7.01 to 8.0, in 8.0 the OCHTRAIL circuits are reported as OOS[PARTIAL]. Indeed the two terminal nodes (Source and Destination) report state as OOS,DSBLD. TL1 and TCC report their states as IS-NR.
CSCsg29444
On rare occasions, the STM64 4-port DWDM card may into continuous resets after a node power down. A hard reset of the card usually brings it up normal.
CSCsd00882
In an IDRI setup, with an exiting SRG Violation between one of the rings and the IDRI hand-off spans, the SRG Violation Warning prints the same span twice. This happens only when the circuit is routed manually on a BLSR-path protection or a path protection DRI/IDRI. The functionality of the Circuit Routing is as expected. The one violation gets printed twice because the DRI span traverses twice.
CSCse96118
RTRV-COND-STS does not display path alarms on BLSR protect path. When BLSR is switched onto protection and the protect paths have conditions on them, the TL1 retrieval command does not show those conditions on protection paths.
CSCse53133
RTRV-COND-STS does not display path alarms on BLSR protect path. When BLSR is switched onto protection and the protect paths have conditions on them, the TL1 retrieval command does not show those conditions on protection paths.
CSCsb88234
When a card is provisioned and a filler card is plugged in, a DBCHG with ENT-EQPT is sent, but when a filler card is plugged in without a prior provision there is no plug-in message. Similarly, there is no message upon removal of the filler card. The workaround for TL1-NONE, is to issue an inventory call and the filler card appears. For CTC, the card is displayed and removed when the card is removed.
CSCsg03334
After ML card reset, system comes up with POS0=PSAS true. When nodes from Release 6.2 are activated with ML V-up enabled and there is a soft reset of the ML cards to clear SW-MISMATCH, the ML cards come up with PSAS on for POS 0. Consequently, the port does not report any alarms (only conditions) for eight hours. The NE Default is off for PSAS, so POS 0 should not have PSAS on. The workaround is to manually reset PSAS flag to FALSE.
CSCsg10963
Connections remain in OOS-AU,FLT after roll is cancelled. This occurs under the following conditions:
1.
2.
3.
4.
UNEQ-P alarms clear and connection states remain OOS-AU,FLT.
CSCsg16500
ROLL-PEND condition is seen for VT circuits on the CTC conditions pane.
1.
2.
3.
4.
The ROLL-PEND condition is now visible on VT circuits in CTC, TL1.
CSCsg32263
When DBCHG messages are turned on by using the ALW-MSG-ALL command, there is no DBCHG message when creating and then deleting a proxy firewall tunnel.
CSCse22576
CTC BLSR views not updated properly after consecutive ENT-MSSPR commands. After entering 16 consecutive ENT-MSSPR TL1 commands across three nodes, the CTC does not update the NetView > BLSR table. The workaround is to restart the CTC so it shows the screens properly. This issue will be resolved in a future release.
CSCse91968
The AINS-to-IS transition on BLSR 4F Protect not functioning properly. When a BLSR 4fibre ring is used, the AINS-to-IS transition is not correct when protect is active (ring switched). Sometimes the wrong protect is transitioning at the IO. If the TSC is notified incorrectly, it becomes out of sync with the IO, and becomes stuck in AINS, even when the protect switch is released. The PCA is also being incorrectly notified of an AINS-to-IS transition. This issue will be resolved in a future release.
CSCse92248
System does not declare TIM-P or retrieves received J1 Path Trace value on switched BLSR. With BLSR switched onto the protect. With the J1 path trace value changed on one node, the receiving node is not retrieving the new J1 Path Trace value and, therefore, is not raising the TIM-P alarm. This issue will be resolved in a future release. This issue will be resolved in a future release.
CSCsf01901
Standby TSC may continuously reboot and Node may loose visibility when there is a huge number of alarm transitions on the node for more than an hour. The standby TSC should be hard reset and the visibility will be regained. This issue will be resolved in a future release.
CSCsf96856
Database Restore may fail with a large database. When restoring a large database with full-capacity cross connects, alarms, and PM databases, the restoration through CTC may fail with an error. A workaround is to attempt the database operation again and it usually succeeds. This issue will be resolved in a future release.
CSCsg00090
There is no response when command "RTRV-TH-STS1::all:1;" is issued. Expected behavior is a DENY response with the correct error message or COMPLD response with the appropriate threshold values displayed. This issue will be resolved in a future release.
CSCsg16680
RTRV-PM-<mod2_path> does not display any PM counts for ALL aid. The TL1 command is COMPLD, but nothing displays. This issue arises when 2F-BLSR circuits are provisioned with IPPM enabled and B3 errors are injected and where some PM counts are generated. Then, STS12c circuits are created and the command RTRV-PM-STS12c::all:1 is executed. Otherwise, RTRV-PM-ALL works fine, and RTRV-PM-<mod2_path> with individual AID works normally.
CSCsg13597
After pulling line cards out of shelves involved in the DCC between nodes a EOC alarm was raised and did not clear after the cards were re-inserted.
"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
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.
CSCsj39710
In CTC Card View, Maintenance Pane, the Loopback Type is displayed as False. The parameter has to be set to True. A workaround is to manually set the parameter to True.This is for the release(s) prior to 8.0.
This is for cards STM1, STM-4, STM-16, and STM-64.This issue is resolved in this release.
Ethernet Polarity Detection
The TCC2/TCC2P does not support Ethernet polarity detection. The TCC+ and TCCI both support this feature. If your Ethernet connection has the incorrect polarity (this can only occur with cables that have the receive wire pairs flipped), the TCC+/I will work, but the TCC2/TCC2P will not. In this event, a standing condition, "LAN Connection Polarity Reverse Detected" (COND-LAN-POL-REV), will be raised (a notification will appear on the LCD, and there will be an alarm raised). This issue will most likely be seen during an upgrade or initial node deployment. To correct the situation, ensure that your Ethernet cable has the correct mapping of the wire wrap pins. For Ethernet pin mappings, consult the user documentation.
Optical IO Cards
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
Electrical IO Cards
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.

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.

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

Setting a Terminal loopback on an MXP-2.5G-10G trunk port causes OTUK alarms.
This can occur under the following conditions.
1.
2.
3.
4.
This terminal loopback causes OTUK-LOF and OTUK-IA alarms to be reported on both MXP-2.5G-10G trunk ports. This issue will not be resolved.

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
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
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
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
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
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
This causes the far end trunk to switch from protect to working span. Similarly, removal of the receive Client fiber at far end causes the near end trunk to switch from the protect to the working span. (Note that the traffic is already lost due to the receive client fiber pull.) To work around this issue, manually switch via CTC from the working to the protect span. This issue will not be resolved.

Incorrect ALS initiation causes a traffic outage on an FC payload. This issue can be seen by performing the following steps.
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
Step 9
ALS is now initiated on TXP-1 port 2 (trunk) and the laser shuts down. Traffic never comes back.
Note
To recover from this situation, perform a manual restart or disable the ALS in this configuration. This issue will not be resolved.
CSCuk51184
When downloading Release 4.7 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
Step 2
Step 3
Now, when you click Apply, CTC issues the error message: "Error applying changes to row2 peer trunk port must not be IS." Port 3 is still IS and the loopback changes are not applied. You must place Port 3 in the OOS-MT state, apply the changes, and then change the loopback to recover.
This error occurs only when all three of the above changes are attempted at the same time.
To avoid this issue, first change both the trunk ports to OOS-MT, click Apply, and then place port 2 in loopback and click Apply again. This issue will not be resolved.
CSCed76821
With Y-cable provisioned for MXP-MR-2.5G cards, if you remove the client receive fiber on one side, the far end takes greater than 100 ms to switch away from the affected card. This issue will not be resolved.
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
Step 2
Step 3
Step 4
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.
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.
