Caveats
This section lists the caveats and corrected caveats for each release. Use Table 3 to determine the status of a particular caveat. In the tables, "C" indicates a corrected caveat, and "O" indicates an open caveat.
This section describes the caveats in the Cisco ONS 15540 ESP.
Symptom: If you attempt to change or edit a threshold in the threshold list that is already associated with an interface, the threshold is applied to that interface even when no changes are made to it. Usually the change in error counts are more important than the error counters themselves.
Workaround: Issue the clear counters command.
Symptom: If CiscoView files are extracted on a Flash disk (disk0: or disk1:), the package does not work.
Workaround: Install CiscoView on a Flash PC Card (slot0: or slot1:).
Symptom: When there is a constant stream of loss of sync alarms, a port fail notification is not generated.
Although both signal failure and signal degrade thresholds are applied, only signal degrade is observed. The signal failure threshold is monitored by hardware registers. When the signal failure threshold is exceeded, the hardware normally generates a port fail notification. Because the loss of sync alarms are constant, the threshold exceeded cannot generate a port fail notification. The signal degrade is reported because it is monitored by software and does not need any notifications from hardware.
Workaround: Disable and reenable monitoring once with the no monitor/monitor enable command sequence to generate the port fail notification.
Symptom: Upon switchover, the active processor card can become nonresponsive. The processor card Active LED remains on, even though it is no longer actively controlling the system.
Workaround: None
Remove and reinsert the processor card to correct the fault.
Symptom: The ROMMON might continuously loop in an attempt to autoboot a missing system image.
Continuous looping happens when autoboot is configured in the configuration register (0x2102), but the system image corresponding to the system boot filename command in the startup configuration is missing and no alternate system boot filename command is configured for an existing system image.
During normal system functioning, the system first checks for system image file names in the startup configuration system boot filename commands. If there are none, or the images are not valid, the system checks the Flash device in slot0: and then bootflash for loadable images before stopping its attempts to autoboot.
Workaround: Configure at least one system boot filename command for an existing system image on both processor cards before reloading either processor card.
If autoboot looping occurs, issue a console send break command during the first few seconds of a reload attempt to stop autobooting. Then manually boot the system using a valid system image in Flash memory or on the network.
Upgrade the processor card ROMMON image to release 12.1(11r)E3 or later.
Symptom: If during a netboot attempt the processor card fails to netboot or the peer processor card changes its Active/Standby state, any further changes to the peer processor card Active/Standby state are ignored until a reset command is issued at the processor card ROMMON prompt.
Workaround: Issue a reset command at the ROMMON prompt after failing to netboot.
Upgrade the processor card ROMMON image to release 12.1(11r)E3 or later.
Symptom: An error can occur with management protocol processing. Please see the following URL for more information:
http://www.cisco.com/cgi-bin/bugtool/onebug.pl?bugid=CSCdw65903Workaround: None
Symptom: Following a Cisco IOS software crash, a second ROMMON exception might cause the original stack trace to be lost. This happens if a pending PCI (peripheral component interconnect) bus interrupt was in progress but was not handled before the IOS crash.
Workaround: Upgrade the processor card ROMMON image to release 12.1(11r)E3 or later.
Symptom: The following errors might occur:
–
–
–
–
Workaround: None.
Symptom: The system power cycles and the standby processor card startup configuration is not synchronized with the active processor card startup configuration. If this occurs, then the previous standby processor card might become the active processor card and a different set of connections might be set up.
The standby processor card startup configuration can become outdated when it is in maintenance mode.
Workaround: Remove the standby processor card from the shelf when it is not in use.
Upgrade the processor card ROMMON image to release 12.1(11r)E3 or later.
Symptom: Loopback cannot be configured on the wave interface of an extended range transponder module if no transceiver is present. The loopback command is accepted but the loopback is not configured.
Workaround: Insert a transceiver before configuring the loopback on the wave interface.
Symptom: When laser safety control is enabled on the OSC wave 0 interface or wave 1 interface, the OSC trunk laser does not shut down when a fiber cut occurs.
Workaround: None
Symptom: Loss of Signal may be encountered before SD (signal degrade) and SF (signal failure) thresholds are exceeded and traffic may still continue to pass transparently.
The loss of signal detection is taken from the OE conversion subsystem which is different from the source of the SD and SF counters. The OE conversion is not gated by its loss of light indication so the data and clock extraction continues and the signal is regenerated transparently. The loss of light sensitivity is a characteristic of the OE conversion unit and it may vary from unit to unit but is always < -30dBm.
Workaround: None.
Symptom: The alarm LED is not raised or cleared by SD/SF indications.
Workaround: None.
Symptom: If the configuration register autoboot field is set to either 0x1 or 0x2 and the first file in bootflash memory is not a loadable system image, then the system continues to try to reboot.
Workaround: Use the send break command on the console CLI to stop the autoboot cycling, and then manually boot a loadable system image. Make sure the first image in bootflash memory is a valid system image.
Upgrade the processor card ROMMON image to release 12.1(11r)E3 or later.
Symptom: With APS Y-cable, SD condition on the working channel does not clear the lower priority manual-switch condition on the protection channel. This caused manual-switch to persist after the SD condition was removed and APS to switch back to the working channel.
Workaround: None.
Symptom: Customer installed mismatching wavelength transponders and did not receive a wavelength mismatch alarm. The Cisco ONS 15540 ESP does not report this condition.
Workaround: None.
Symptom: When the Rx port fiber is removed, ingress alarms are reported and cleared repeatedly. The alarm should not clear and the alarm should be reported only once.
Workaround: None
Symptom: Processor card gets into a nonresponsive state.
Workaround: None
Symptom: No alarm is raised when the transponder channel does not match the channels supported by the mux/demux module.
Workaround: None.
Symptom: CTM is flooded with traps every second when hardware port flap alarms occur.
Workaround: None.
Symptom: The encapsulation fastethernet command fails on multimode transponders. The clock rate 100000 command succeeds but then pings over the signal fail intermittently.
Workaround: None.
Symptom: The OSC intermittently drops IP packets because of an erroneous calculation of the FCS-16 (frame check sequence 16).
Workaround: None.
Symptom: The system image on the standby processor card cannot be upgraded to a new system image because the format of the redundancy messages from the active processor card are not recognized on the standby processor card. The standby processor card fails to boot and returns to ROMMON mode.
Workaround: None.
Symptom: The transparent interface of an extended range transponder module continues to report good signal quality even after the transceiver is removed and reinserted.
Workaround: Perform a shutdown/no shutdown command sequence on the transparent interface.
Symptom: A transparent interface carrying Gigabit Ethernet traffic and configured with gigabit Fibre Channel encapsulation shows good quality signal on the show interfaces transparent command output and does not assert any ingress alarms. The wave interface assert loss of lock and loss of sync alarms.
Workaround: Remove and reinsert the transponder module to bring it to the correct state.
Symptom: LoF (loss of frame) alarms are not reasserted after a shutdown/no shutdown command sequence on both the transparent and wave interfaces on the transponder module.
Workaround: Disable and reenable monitoring on the transparent interface to reassert the alarms.
Symptom: A line laser failure alarm is asserted but not cleared when an extended range transponder module is removed and reinserted. The show facility-alarm status command output shows a message similar to the following:
Source: TranspdrSC 2/3 Severity: MAJOR Description: 2 Line laser failure detectedWorkaround: None.
Symptom: The SF (signal failure) alarms are not cleared from the show facility-alarm status command output after monitoring is disabled.
Workaround: None.
Symptom: An ingress LoF alarm on a transparent interface is not asserted when an SEF (severely errored frames) alarm is present due to the alarm priority handling error in driver.
Workaround: A shutdown/no shutdown command sequence on the transparent interface will reassert the ingress LoF alarm.
Symptom: If a Downlink Client interface is configured for CDL but is connected to a non-CDL device, the CDL message channel is down.
Workaround: Ensure Downlink Client interface is configured correctly.
Symptom: Unknown vendor type for Wavepassthru interface in Entity MIB.
Workaround: None.
Symptom: In a configuration where two Cisco ONS 15530 systems are linked to a Cisco ONS 15540 ESP through 10-GE connections, the tengigethernetphy interface on one side is administratively shut down and the ESCON ports are down. However, the ESCON ports associated with the other Cisco ONS 15530 are still up.
Workaround: Shut down the tengigethernetphy interface associated with the second Cisco ONS 15530.
Symptom: Configuring both line and trunk side loopback on the 10-GE trunk card affects the Traffic flow.
Workaround: Reconfigure the 10-GE trunk card with loopback on only line or trunk side, not both. OIR the 10-GE card to restore traffic.
Symptom: CDL hec counters are displayed in the show interface tengigethernetphy when CDL is disabled.
Workaround: None.
Symptom: Traffic is disrupted on bootup and switchover when the client side of the 10-GE trunk card has CDL disabled and both the client side and the trunk side are configured for cdl force hop
Workaround: Use the no cdl defect-indication force hop command on the client side.
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.
•
•
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.
