CSCed74239

Symptom: Though the working trunk has a failure, the protection path may not become active for a Y-cable APS link when the client device is administratively shutdown and restarted.

Conditions: The symptom may be observed on some FC devices connected to 2.5-Gbps transparent transponder cards.

Workaround: Configure a loopback interface on the client side to restore the traffic.

CSCeb79990

Symptom: The patch commands saved on the system are not compatible with CTM (Cisco Transport Manager).

Workaround: Remove the patch commands that show up out of order after the configuration is saved. Then, reset the active processor card or switch to the standby processor card and reenter the patch commands.

Symptom: During normal operation, an outage may result when trying to connect through the console port. The console port issues error messages. These can be routine messages relating to Loss of Light on wave ports that were enabled. Interface alarm flapping may cause a hardware watchdog timeout that failed to switchover to the standby processor card.

Workaround: None

CSCee75578

Symptom: The GE optical link fails to come up between two Catalyst 65xx 8-port GBIC modules through the Cisco ONS 15540 transparent transponders when Forward Laser Control (FLC) is enabled on the system. The link fails to come up irrespective of the type of protection scheme.

Workaround: Use a 16-port GBIC module on the Catalyst 65xx or deactivate FLC on the Cisco ONS 15540.

CSCef12108

Symptom: The Cisco ONS15540 might not allow you to connect to the standby processor card due to an authentication failure. This occurs when AAA or a local database is used for user authentication as this information (AAA or local database) is not replicated from the active to the standby processor card.

Workaround: None.

CSCsb38669

Symptom: When there are no connections on the OSC wave interface, the state of the interface and the line protocol must be down, and signal quality must be Loss of Light. But, the show interface command incorrectly displays the wave interface state as up, and the signal quality as good.

Conditions: The symptom is observed only when the PSM is inserted in subslot 0 of the motherboard.

Workaround: Insert the PSM in any other subslot.

CSCin86897

Symptom: A temporary traffic interruption in 2.5G transparent transponders during ONS 15540 and 15530 CPU switchover. This depends on the software versions of the Active CPU before and after the switchover. When the switchover is complete, traffic resumes. This symptom is intermittent and may not affect all transponders in a chassis.

The traffic interruption may occur for the following types of encapsulation:

- ETR/CLO

- 100-Mbps Fast Ethernet / FDDI

- 1-Gbps FC/FICON

- 1-Gbps ISC (ISC-1, ISC-3 peer mode, 1-Gbps)

- 2-Gbps FC/FICON

- 2-Gbps ISC (ISC-3 peer mode, 2 Gbps)

Conditions: This can occur when switching from a CPU that is running on IOS software without the fix for CSCec64326, to a CPU running on IOS software with the fix for CSCec64326. The fix for CSCec64326 involves changes to hardware settings, causing the temporary datahit.

Workaround: None. The problem will be fixed in a future release of IOS software.

CSCsa51395

Symptom: The client Laser on the ten gig interface goes down for around 4 to 5 seconds, when the FLC is configured on the waveethernetphy interface and PSM APS switchover happens on an ONS 15540 setup with a combination of 10GE transponder and PSM APS.

Workaround: Disable FLC on Waveethernetphy interface.

Resolved Caveats in Release 12.2(29)SV

CSCsb26802

Symptom: When a client or trunk laser fails, the show facility-alarm status command displays the Line laser failure detected error message. However, this error message does not indicate which laser has failed.

Condition: This symptom is observed on Cisco ONS 15540 ESPx cards when there are transparent transponders.

Workaround: None.

CSCsb97958

Symptom: Adding a Cisco ONS 15540 in to CiscoWorks Resource Manager Essentials 4.0 fails with RICS0001 error.

Condition: This symptom is observed while adding a Cisco ONS 15540 that is running on Cisco IOS Release 12.2(18)SV2.

Workaround: None.

CSCsb35798

Symptom: The Cisco ONS 15540 ESPx node may reload on performing shut/no shut on the wavee or wavepatch interface.

Conditions: This symptom is observed if the optical monitoring trap is enabled on the node.

Workaround: None.

CSCsc51288

Symptom: Cisco Transport Manager (CTM) does not retrieve the software version of the standby CPU of Cisco ONS 15540 ESPx, and marks the related network element (NE) as unreachable.

Conditions: This symptom is observed with Cisco IOS Release 12.2(24)SV or later. The symptom may not occur if the NE is lightly equipped (few transponder modules).

Workaround: None.

CSCed75110

Symptom: If a protection switch module (PSM) is placed in subslot 0 of a LCMB, the optical supervisory channel (OSC) wave interface goes into an invalid state. The OSC recovers when the PSM module is removed from subslot0. If the chassis is reloaded with the PSM in subslot 0, the OSC wave interface will not be operational.

Workaround: Do not place the PSM module in subslot0 of the LCMB if the OSC port on that LCMB is being used.

CSCee70185

Symptom: An informational warning is issued instead of a critical alarm when the line cards are shut down in response to a multiple fan failure event after issuing the environment-monitor shutdown fan command.

Workaround: None.

CSCsa71267

Symptom: The Cisco ONS 15540 ESP system does not shutdown if the fan tray is removed or is faulty.

Conditions: None.

Workaround: None.

Resolved Caveats in Release 12.2(26)SV1

CSCuk58617

Symptom: The physical Performance Monitoring (PM) statistics may not be collected correctly.

Condition: This symptom is observed on a Cisco ONS15500 series card that is configured for SNMP when optical monitoring traps are enabled.

Workaround: None.

CSCei25594

Symptom: Memory leak may occur when CiscoView is used to monitor a router.

Condition: This condition may be seen on routers running 12.2(26)SV.

Workaround: None.

Resolved Caveats in Release 12.2(26)SV

CSCeg84037

Symptom: When a CPU switchover is performed on an ONS 15540 or ONS 15530 system, the memory utilization on the new primary increases by 10MB. In such a case, the memory utilization may go up to 85%. This problem is seen only with 12.2 based images.

Workaround: None.

CSCin88118

Symptom: PSM APS switchover may rarely occur on an ONS 15540 system due to false low alarms reported for the wdmsplit interfaces.

Condition: This occurs rarely when spurious low alarms are seen for the PSM wdm split interfaces.

Workaround: None.

CSCsa45294

Symptom: Traffic is disrupted for one to two seconds on ONS 155xx transponders configured with Forward Laser Control, when a protection switchover occurs on a trunk Protection Switch Module (PSM). This exceeds the specification of 50ms maximum failover time for the optical transport layer.

Workaround: Disable FLC on trunk-to-client direction of transponder, if feasible for the service. This workaround does not apply for ISC, ETR or CLO services.

Resolution: This will be fixed in the future release of IOS software on ONS15530 and ONS15540, with a caveat that the following configuration will not be supported on the platform:

Transponder motherboard or linecard with on-board optical splitter module (even if the optical splitter is disabled by configuration)

Trunk protection with Protection Switch Module

Forward Laser Control enabled on transponder

CSCsa46389

Symptom: On an ONS 15540/15530 system with Protection Switch Module, if a CPU switch occurs with the APS state such that protect interface is active and working interface is standby, then after the new CPU comes up there will be an extra APS switch to working. This is seen with all ONS15540 and ONS15530 software based on 12.1 and 12.2.

Workaround: None.

Resolved Caveats in Release 12.2(25)SV

CSCee71928

Symptom: The optical link fails to come up between two 8-port GBIC modules through the ONS15540 PSM DWDMs when forward laser control (FLC) is enabled.

Workaround: Use a 16-port GBIC module or deactivate FLC.

CSCin76822

Symptom: If a failed subcard is replaced by a new one, the show diag online output continues to indicate that there was a 'previous failure' for this subcard. This should have been cleared when the new card was inserted. This is specific to subcards, for motherboards the older failures are cleared when a new card is inserted.

Workaround: None.

CSCin80680

Symptom: The system crashes when the functional image reprogramming is in progress for any of the line cards and the command show upgrade-information functional-image is issued at the same time through vty lines.

Workaround: None.

Resolved Caveats in Release 12.2(24)SV

CSCdz82276

Symptom: A warning is issued if the card has an unknown functional image. Version compatibility checks need to be performed during system initialization. The hardware version compatibility should identify any mismatch between functional image versions and hardware versions. The software version compatibility should identify any mismatch between the functional image and software image.

Workaround: None.

CSCec45305

Symptom: If the transparent interface on a multimode transponder module is configured for Sysplex ETR traffic (encap sysplex etr command), the show interfaces transparent command output shows that forward laser control is set to off. Forward laser control is automatically enabled for Sysplex ETR.

Workaround: Add client input traffic and the trunk side laser will function.

CSCec55713

Symptom: The Prot Switch Byte Failure - In Effect alarm message appears on the console.

Workaround: None.

CSCec55713

Symptom: The Prot Switch Byte Failure - In Effect alarm message appears on the console.

Workaround: None.

CSCec78648

Symptom: The show redundancy command is not valid on specific versions of the Cisco ONS 15540 ESP software but the choice still exists.

Workaround: Use the show redundancy summary command.

CSCee50294

Symptom: Cisco IOS® devices running branches of Cisco IOS version 12.2S that have Dynamic Host Configuration Protocol (DHCP) server or relay agent enabled, even if not configured, are vulnerable to a denial of service where the input queue becomes blocked when receiving specifically crafted DHCP packets. Cisco is providing free fixed software to address this issue. There are also workarounds to mitigate this vulnerability. This issue was introduced by the fix included in CSCdx46180 and is being tracked by Cisco Bug ID CSCee50294.

This advisory is available at

http://www.cisco.com/warp/public/707/cisco-sa-20041110-dhcp.shtml.

Workaround: None.

CSCee75578

Symptom: The GE optical link fails to come up between two Catalyst 65xx 8-port GBIC modules through the Cisco ONS155xx transparent transponders when Forward Laser Control (FLC) is enabled on the system. The link fails to come up irrespective of the type of protection scheme.

Workaround: Use a 16-port GBIC module on the Catalyst 65xx or deactivate FLC on the Cisco ONS 15540.

CSCin69960

Symptom: A receive failure might display a message that the laser is shut due to forward laser control.

Workaround: None.

Resolved Caveats in Release 12.2(23)SV

CSCec31146

Symptom: If monitoring is disabled, Loss of Light on the local transparent interface results in Loss of Sync on the far side wave interface.

Workaround: Enable monitoring on the transparent interface.

CSCed38657

Symptom: DWDM links set at a 196.608-Mbps rate, or an uncommon rate close to this, may not work properly on the 2.5-Gbps transponder module. Link initialization failures and bit errors may occur.

Workaround: None.

CSCee34107

Symptom: APS behavior for the aps clear command is inconsistent with the standard behavior if the following conditions occur:

Traffic runs from the working link (link A) and you perform a manual switch to the protected link (link B), causing traffic to switch to link B.

You enter the aps clear command for the aps-group; link A becomes active, regardless of whether the APS group is configured revertively or nonrevertively.

Workaround: None.

CSCeb70408

Symptom: The IDPROM values from the high band single-mode SFPs are not readable. The SFPs cannot be configured and cannot be used.

Workaround: None.

Resolved Caveats in Release 12.2(22)SV

CSCeb18103

Symptom: The OSC wave interface does not come back up after resolving a trunk fiber break if laser safety control was configured after the trunk fiber break occurred.

Workaround: None.

Resolution: Upgrade the Cisco ONS 15540 mux/demux motherboard functional image to release 2.67 or later.

CSCin60562

Symptom: If a row is created in cApsChanConfigTable using createAndWait, a set operation on an instance of cApsChanConfigIfIndex might modify another instance of that object.

Workaround: Use createAndGo to create the row.

CSCin67971

Symptom: If a one-way patch configuration is removed between a thru interface and a wdm interface, the system hangs for a long time and eventually crashes.

Workaround: Configure two-way patches between the thru and wdm interfaces.

Resolved Caveats in Release 12.2(18)SV2

CSCeb87507

Symptom: In some instances the system crashes when it attempts to parse IP SNMP related commands.

Workaround: None.

CSCed22589

Symptom: Link initialization failure due to Loss of Lock might occur for ESCON traffic on some transponder modules due to a transient failure of the clock recovery unit. Only some transponder modules are susceptible to this failure and not all. This is an initialization failure and not a run-time failure.

Workaround: None.

Resolved Caveats in Release 12.2(18)SV1

CSCec28182

Symptom: Tracebacks related to processor hog issues are seen when reprogramming the 2.5-Gbps transponder module functional image.

Workaround: None.

CSCec59409

Symptom: Issuing a Ctrl-U when connected to a raw TL1 port causes the system to crash.

Workaround: If a TL1 port is unused, apply an IP ACL to the management Ethernet interface that blocks the incoming TCP connections to that port.

Resolved Caveats for Release 12.2(18)SV

CSCdu53656

A Cisco device running Cisco IOS software and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. The BGP is not enabled by default, and must be configured to accept traffic from an explicitly defined peer. Unless the malicious traffic appears to be sourced from a configured, trusted peer, it would be difficult to inject a malformed packet. BGP MD5 is a valid workaround for this problem.

Cisco has made free software available to address this problem. For more details, refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20040616-bgp.shtml.

CSCeb61427

Symptom: The system crashes when the user exits from the console after the active processor card has been removed and inserted online and is switched back to being the active processor card.

Workaround: None.

CSCeb72528

Symptom: Client Tx fault alarm is asserted when an SFP optics is inserted or upon a y-cable switchover.

Workaround: Upgrade to Cisco IOS Release 12.1(12c)EV3 and transponder functional image version 1.A2 or higher.

CSCec05746

Symptom: In a point-to-point network topology setup where bidirectional PSM trunk fiber protection APS is configured, and the CDL (Converged Data Link) is configured for dcc and the controller type of the mux/demux module is 0x1104 (4-channel mux/demux module without OSC), APS cannot to track a valid ethernetdcc interface. Therefore the group cannot be associated.

Workaround: Do not configure CDL as dcc for PSM APS if the corresponding mux/demux module does not have OSC ports (controller type 0x1104).

CSCec22377

Symptom: Continuous optical performance monitoring alarms cause memory leaks that lead to bus error exceptions and an unexpected reload.

Workaround: None.

CSCec31503

Symptom: Unable to disable APS group through SNMP. The console or Telnet session hangs indefinitely after configuration mode is entered using the SNMP set command.

Workaround: Do not disable the APS group through SNMP.

CSCec31512

Symptom: When you enter the send break command on the active processor and keep the active processor in the ROM monitor (ROMMON) mode for a long time, the standby processor may reload because of a bus error exception.

Workaround: None.

Limitations and Restrictions

This section provides limitations and restrictions for Cisco ONS 15540 ESP hardware and software.

Transponder Modules

This section contains limitations and restrictions that apply to transponder modules.

When you insert the standby transponder module in a y-cable protected configuration, remove the cable from the transponder module before inserting the transponder module into the shelf. Failure to remove the cable might result in errors that can affect the performance of the active signal received by the client equipment.

CRC errors may occur with 2-Gbps Fibre Channel on single-mode transponders when high input power levels are received from the client laser sources.

Data errors or link-down conditions for 2-Gbps Fibre Channel might occur when used with certain client laser sources. Transmitters in some client GBIC and SFP transceiver units might send large overshoots in optical power with signal bit transitions, causing momentary overload conditions on the transponder client side receiver. The average transmitted power level from the GBIC does not violate the overload specification of the transponder client side receiver, so a power meter does not detect the overload.

The workaround is to attenuate the signal from the client equipment to a recommended level of -12 dBm when transmitting 2-Gbps Fibre Channel services.

Error-free transmission of some D1 video signals (defined by the SMPTE 259M standard) and test patterns (such as Matrix SDI) cannot be guaranteed by the Cisco 15500 Series because of the pathological pattern in D1 video. This well-known limitation is usually overcome by the D1 video equipment vendor, who uses a proprietary, second level of scrambling. No standards exist at this time for the second level of scrambling.
