Caveats
This section lists the caveats for each release. Use Table 3 to determine the status of a particular caveat. In the table, "C" indicates a corrected caveat, and "O" indicates an open caveat.
This section describes the caveats in the Cisco ONS 15530.
Symptom: The system can reload unexpectedly if there are APS groups configured on 8-port FC/GE aggregation card interfaces and there is a state change of one or more of the ports or cross-connected interfaces.
Workaround: None.
Symptom: If multiple APS groups are configured, and one group is in not associated state because there are working and protection ports in the admin down state, any Rx fail and recover of other groups causes both lasers to turn on in those groups.
Workaround: Disable the APS group if ports of any APS groups are in admin down state.
Symptom: Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to a Denial of Service (DoS) attack. A rare sequence of crafted IPv4 packets sent directly to the device may cause the input interface to stop processing traffic once the input queue is full. No authentication is required to process the inbound packet. Processing of IPv4 packets is enabled by default. Devices running only IP version 6 (IPv6) are not affected.
Workaround: Cisco has made software available, free of charge, to correct the problem. This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml
Symptom: The show facility-alarm status command output does not show loss of sync, loss of light, or signal failure alarms on a waveethernetphy interface on a 10-Gbps ITU trunk card or 2.5-Gbps ITU trunk card after a shutdown/no shutdown command sequence on the interface. The show interfaces command displays that the alarm persists.
Workaround: None.
Symptom: You cannot reconfigure new cross connections after reinserting a 10-Gbps ITU trunk card if a card fails due to low voltage of another hardware failure and is removed, the flow identifier values programmed in the 10-Gbps ITU trunk card are not cleared. Flow identifier mismatch errors are displayed and cross connections are not established.
Workaround: OIR the 10-Gbps trunk card.
Symptom: Cannot disable SNMP-server traps for TTY messages on a global basis.
Workaround: Configure traps on a per SNMP-server host basis.
Symptom: Both working and protection interfaces come up as the standby when configuring splitter APS using ENT-FFP-OCH. Both of the wavepatch interfaces are up in the transponder line card.
Workaround: Issue an aps enable/disable command sequence or OIR the transponder line card.
Symptom: The y-cable connection does not come up while connected to a Brocade switch.
Workaround: None.
Symptom: If multiple cross connections are created and deleted on an 8-port FC/GE aggregation card, the local or remote system might reload unexpectedly. This rarely happens.
Workaround: None.
Symptom: The no form of VOA attenuation commands might wipe out positive forms those commands
Workaround: None.
Symptom: If a command is partially successful, an error code for the parameter that cannot be modified is displayed.
Workaround: None.
Symptom: An internal error and a traceback results when a threshold group with Tx-CRC failure and Tx-CRC degrade is modified such that the index reaches 63 and there is an attempt to add a new Tx-CRC threshold.
Workaround: None.
Symptom: If a card with a bad IDPROM is detected in the system, the system crashes during bootup or online insertion.
Workaround: None.
Symptom: If a timer is rebooted and the CLO link is up and running, the link briefly turns off the lasers. This is seen as loss of light and the FLC turns off the transmitter laser on the transponder line card. When the timer is back on, the FLC does not turn the transmitter laser on.
Workaround: Issue the shutdown/no shutdown command sequence or OIR the card.
Symptom: If the connect command is executed, which results in traffic intermixing between ESCON/ Fibre Channel/ FICON and Gigabit Ethernet/ ESCON/Fibre Channel/FICON, traffic might slow down if the proper preconfiguration commands are not configured for the corresponding line cards.
Workaround: Configure the required preconfiguration commands.
Symptom: BDI-E (Backward Defect Indication) is asserted on FC/GE interfaces when there is no remote Tx fault. This does not affect functionality.
Workaround: None
Symptom: After a CPU switch module switchover, persistent alarms on an administratively shut interface might be erroneously reported when they exist. When a port interface is administratively down, alarm conditions should not be reported for that interface even though they exist.
Workaround: After a CPU switch module switchover, issue a no shutdown/shutdown command sequence on the already administratively shut interfaces. This ceases to report alarm conditions persistent on the administratively shut interfaces.
Symptom: If an ESCON aggregation card cross connected to a 10-Gbps ITU trunk card is removed and reserved flow identifier configured, reserved flow identifiers are not removed.
Workaround: OIR the 10-Gbps ITU trunk card to clear the flow identifiers.
Symptom: Catalyst 5000 FDDI link does not come up when connected over a Cisco ONS 15530 point-to-point topology using multimode transponders.
Workaround: Set the clock rate to 500 Mhz.
Symptom: The show cdl flow identifier does not show the reserved flow id configured under the portgroup.
Workaround: Use the show interfaces portgroup x/y/z command to display the configured group.
Symptom: After a CPU switch module switchover, if the no shutdown command is issued on the OSC wave interface, it is in the UP state even when the OSC module is not connected to the OADM module.
Workaround: Issue the shutdown/no shutdown command sequence on the OSC wave interface.
Symptom: APS state is not correct after an online removal and reinsertion of the local ESCON aggregation card. This happens only if the following sequence of events occur:
1. Shut down of the remote laser (working path)
2. Removal of the ESCON aggregation card (local)
3. Shut down of the local laser (working path)
4. Insertion of the ESCON aggregation card (local)
After the local ESCON aggregation card is reinserted, the protection waveethernetphy interface does not become active. At this point, the working interface is active even though it is in the down state.
Workaround: Remove and reinsert the protection and working 2.5-Gbps ITU trunk cards.
Symptom: The 10-Gbps ITU trunk card waveethernetphy interface does not come up after the peer laser is turned back on after a CPU switch module switchover. This happens only if a laser shut is carried across the CPU switch module switchover on the local system.
Workaround: Issue a shutdown/no shutdown command sequence on the local waveethernetphy interface
Symptom: If a Cisco ONS 15530 system with a 7.x hardware version of the 10-Gbps ITU trunk card is booted with the ons15530-i-mz.121-12c.ev image, the following warning displays:
Power-on Diagnostics: --------------------- ...................FF.. . ... POD-CRITICAL_WARNING: Slot: 3, Hardware and Firmware are not compatible. ........... .F...... End of POD.Workaround: Turn off power-on diagnostics, save the configuration, and reboot to get rid of the warning.
Symptom: With the duplicate reserved flow identifiers configured and OIR of the ESCON aggregation card, cross connection is rejected, but the client flow identifiers are not removed.
Workaround: OIR the 10-Gbps ITU trunk card.
Symptom: When the active 10-Gbps ITU trunk card in a line card protected configuration is removed, the following warning message displays:
idprom_get_line_wavelength: Unexpected card type: 4360Workaround: None.
Symptom: Both active and standby lasers are on for a few seconds on a y-cable. This condition can cause Brocade ports to be disabled which requires a manual intervention to enable the ports.
Workaround: None.
Symptom: The wave interface goes down after restoring protection trunk failure followed by working trunk failure and restore on a transponder line card configured for unidirectional y-cable protection.
Workaround: Issue a shutdown/ no shutdown command sequence on the wave interface.
Symptom: After booting the system, power coming out of the OSC module seems to be null even though the laser is enabled.
Workaround: OIR the OSC module or carrier motherboard.
Symptom: The protection interface comes up first after an OIR of the 2.5-Gbps ITU trunk card, causing APS to switch to protection channel after OIR of the card.
Workaround: None.
Symptom: With the duplicate reserved flow identifiers configured, if line card protection is configured, both 10-Gbps ITU trunk cards end up in active state.
Workaround: Assign a unique reserved flow identifiers to the ESCON aggregation card ports.
Symptom: No autonomous messages are generated in TL1 for clearing alarms when an escon port is shutdown.
Workaround: None
Symptom: Backplane Ethernet loopback test fails occasionally on 10-Gbps ITU trunk cards.
Workaround: None.
Symptom: With reserved flow identifiers configured under a port group, after a CPU switch module switchover is performed both client and reserved flow identifiers are programmed.
Workaround: None.
Symptom: A keep alive timeout results on an FC interface even with correct flow identifier, cross-connects, and trunk connections.The hardware registers show an Uplink FIFO Full condition in the peer FC interface. No traffic flows out of the peer interface.
Workaround: Change the encapsulation to GE and then change it back to FC or remove and insert the SFP to reset the FIFOs and clear the Full condition
Symptom: The correct hexadecimal value does not display for cifthIfThresholdsFired object for some particular bitmap patterns.
Workaround: None.
Symptom: Unchecked buffer boundary in NTP.
Workaround: None.
Symptom: When the NME is connected to an auto-sensing switch or hub, going from 10 Mbps and half-duplex to 100 Mbps and half-duplex (or similarly 10 Mbps and full-duplex to 100 Mbps and full-duplex) on fastethernet0 results in the link going down.
Workaround: Configure fastethernet0 as duplex auto and speed auto.
Symptom: A change in optical threshold condition at a WB-VOA or PB-OE module power monitor might not be detected if the condition is temporary and does not last for more than a second.
Workaround: None
Symptom: If you swap the ESCON aggregation card with the 10-Gbps ITU trunk card in a given slot, the following error message is seen four times:
%BPE-3-NOT_REGISTERED: Interface[EthernetDcc9/0/0] MAC is not registered.Workaround: None.
Symptom: The CPU switch module LED for alarms is not cleared even though the Optical Power Monitoring alarm is cleared. There is no functionality problem. On a CPU switch module switchover this alarm LED is cleared and gives the correct alarm status.
Workaround: OIR the card on which the alarm was generated.
Symptom: When both wavepatch interfaces are in an administrative down state, a low alarm does not appear on the standby wavepatch interface after a no shutdown is done on the wave interface.
Workaround: Issue the shutdown/no shutdown command sequence on the wavepatch interface.
Symptom: Interface reports up/up even when there is no light source connected.
Workaround: Issue a shutdown/no shutdown command sequence on the interface.
Symptom: A transparent interface carrying Gigabit Ethernet traffic and configured with gigabit Fibre Channel encapsulation shows a good quality signal on the show interfaces transparent command output and does not assert any ingress alarms. The wave interface asserts loss of lock and loss of sync alarms.
Workaround: OIR 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 line card.
Workaround: Disable and reenable monitoring on the transparent interface to reassert the alarms.
Symptom: The show facility-alarm status command status does not report existing LoF/LoSync/LoLock alarms after an OIR.
Workaround: Disable and enable monitoring back to reassert existing alarms in the show facility-alarm status command output.
Symptom: A software compatibility problem causes the active CPU switch module to reset the standby CPU switch module.
Workaround: None.
Symptom: The show hardware command output displays information about a CPU switch module that has been removed from the system.
Workaround: None.
Symptom: Ethernetdcc and OSC wave interfaces come up with default traffic-shaping parameters. Because this is the default, by removing the configuration using the no form of the command, the parameter value should revert back to the default value, which is not being done.
Workaround: Reconfigure the traffic-shaping parameters.
Symptom: If a line card that was removed prior to switchover is inserted during switchover, the line card might not come up properly.
Workaround: Insert the line card after switchover is complete.
Symptom: The system might crash at is_optical_ifstatus_up.
Workaround: None.
Symptom: Issuing a shutdown command on the active wavepatch of a nonsplitter card brings the waveethernetphy interface down and reports loss of light in the output of the show interfaces command, but traffic continues to flow.
Workaround: If the intent is to stop traffic, issue a shutdown command on the waveethernetphy interface or wave interface.
Symptom: Following a CPU switch module crash and switchover, the show redundancy command issued on the new active CPU switch module displays "Not known" for the Reported Switchover Reason field.
Workaround: Enter show version from the standby CPU switch module console to see additional information.
Symptom: The getnext and getbulk commands do not function properly after a CPU switch module switchover.
Workaround: None.
Symptom: APS traps mode mismatch takes 30 minutes for completion.
Workaround: None.
Symptom: Low alarm is not cleared on the wavepatch interface on a transponder line card.
Workaround: Issue a shutdown/no shutdown command sequence on the wavepatch interface where the alarm is seen.
Symptom: On the 10-Gbps ITU trunk card, the CDL HEC and CRC error counters are not incremented upon reaching the threshold limits.
Workaround: None.
Symptom: When trying to modify the cApsConfigSpan object through SNMP is set to an unsupported value, the value is not set but no error is reported.
Workaround: None.
Symptom: Administrative shutdown on a waveethernetphy subinterface does not take affect. The displayed in the command output is "admin shut" but all the traffic flows through and the subinterface is fully functional.
Workaround: None.
Symptom: After removing and reconnecting the fiber cable, the active wavepatch on the transponder line card is down even after unshutting the wave interface.
Workaround: Use a shutdown command to clear the alarms on the wave interface.
Symptom: Spurious memory access is seen when issuing the show tech command on the standby CPU switch module.
Workaround: None
Symptom: PTOPO configuration rows can be configured for nonexistent interfaces.
Workaround: None.
Symptom: The show connect intermediate command output does not display all the protection paths when a switch fabric cross connect is used.
Workaround: Display the information using the show connect command.
Symptom: The active CPU switch module incorrectly detects a faulty switch fabric port, causing a switchover to the standby CPU switch module.
Workaround: None.
Symptom: When copying or reading a file to or from Compact flash (disk0), a transient error with the following message might appear and read/write access to compact flash is terminated:
ATA_Status timeout waiting for <1/2/3>
Workaround: None.
Symptom: Defect-indication error messages do not indicate if the defect-indication bit was cleared or asserted for that interface.
Workaround: None.
Symptom: Some interfaces are not be available to the NMS station since the agent does not create them on OIR.
Workaround: Reload the system after removal/insertion of the cards.
Symptom: APS message channel configured for UDP/IP does not work over two IP hops. The UDP/IP packets are dropped at the end of the second hop.
Workaround: None.
Symptom: Loopback interfaces cannot be deleted from configuration.
Workaround: None.
Symptom: Switch fabric protection is not disabled if the standby CPU switch module is in ROM monitor mode. As a result if an RxFail is noticed on any fabric port, that fabric port will switch over its receive to the standby CPU switch module.
Workaround: None.
Symptom: The redundancy reload shelf command on the active CPU switch module can cause a switchover if the peer CPU switch module is in ROM monitor mode.
Workaround: Use the reload command to reload the active CPU switch module, if the peer CPU switch module is in ROM monitor mode.
Symptom: Issuing getbulk command to retrieve PM parameters returns 0 row.
Workaround: None.
Symptom: The ciscoFlashPartitionFileCount returns an incorrect number of files on the CompactFlash card.
Workaround: None.
Symptom: No ciscoFlashDeviceChangeTrap trap is generated when a CompactFlash device is removed or inserted.
Workaround: None.
Symptom: When forward laser control is disabled on all 10 esconphy ports and they are administratively shut down, packets are still sent to the backplane.
Workaround: None.
Symptom: OPM feature does not work for nonsplitter transponder line cards.
Workaround: None.
Symptom: Invalid mac-address or ip-address values can be made via SNMP. No error check is done.
Workaround: Delete the entry through SNMP or with the topology neighbor disable command.
Symptom: Egress Loss of Signal alarm is not reasserted in the show facility alarm status command output after the hardware module power is turned off and turned back on.
Workaround: None.
Symptom: Incorrect alarms are reported on wavepatch interfaces when the parent wave interface is Admin shut.
Workaround: None.
Symptom: If a system is rebooted and a transient link failure condition occurs on 10-Gbps ITU trunk cards or 10-Gbps uplink cards, the system might continuously send backward defect indications.
Workaround: None.
Symptom: Error messages appear when a 10-Gbps ITU trunk card or 10-Gbps uplink card with crossconnects to the switch fabric is removed.
Workaround: None.
Symptom: The wavepatch interfaces are stuck in the down state after using the shutdown/no shutdown command sequence on the wave interface with splitter APS after the trunk fiber has been cut.
Workaround: None.
Symptom: If the peer node is rebooted, the interfaces connected to that node experience some flaps in the bootup sequence. These flaps trigger unnecessary APS flaps in the near-end node.
Workaround: None.
Symptom: After a fiber cut, the OSC wave interface remains up with signal quality GOOD.
Workaround: Use the shutdown/no shutdown command sequence on the OSC wave interface.
Symptom: The standby CPU switch module can be stuck in trying to register control ports.
Workaround: Enter the redundancy reload peer command on the active CPU switch module.
Symptom: In bidirectional APS, if both NEs (network elements) have the same priority request, the master/slave determination fails, leading to both claiming the control and resulting in not sending a REVERSE-REQUEST.
Workaround: None.
Symptom: When a shutdown/no shutdown command sequence is done on a waveethernetphy interface that is in the UP state, the Signal Condition shows Loss of Lock.
Workaround: None.
Symptom: In bidirectional line card protection, if the APS group is associated with a working interface with an invalid cross connect invalid and protection interface with an active cross connect, APS erroneously sets the APS channel request on the working to WAIT-TO-RESTORE. This does not recover even when the working cross connect is made dormant by the connection manager. As a result both NEs are stay protection until an event (that has higher priority than WTR) is triggered.
Workaround: None.
Symptom: Splitter APS protection comes up as active on system bootup.
Workaround: None.
Symptom: Dynamic discovery of topology via CDP on the tengigethernetphy interface is not configurable.
Workaround: None.
Symptom: In a preconfigured APS group (for the case when the interfaces do not exist), if the group is configured for revertive mode, it cannot be enabled.
Workaround: Enable the group after the interfaces defined in the APS group are created or remove the revertive configuration from the preconfigured APS group and then enabling the group.
Symptom: The CPU switch module crashes after midnight with optical performance monitoring on when an interface capable of performance monitoring is shut down before 00-00hrs and unshut after midnight.
Workaround: None.
Symptom: In unidirectional revertive APS, after online removal is followed by online insertion of working and protection elements on both NEs, the active signal might be received from the protection line instead of the working line.
Workaround: Do a manual or force switch to working line.
Symptom: SEF errors are repeatedly asserted on the console and are not soaked.
Workaround: None.
Symptom: When an interface is shut down administratively, the show aps detail command shows the channel request as sf-lp; however, a get on the object cApsChanStatusCurrent does not reflect sf-lp in the corresponding bits.
Workaround: None.
Symptom: A connection to a different subinterface on the same 10-Gbps ITU trunk card or 10-Gbps uplink card is accepted, but crossconnection fails in the switch fabric.
Workaround: None.
Symptom: The MTU setting on the 10-Gbps ITU trunk card interface is not displayed in the show interfaces command output. Transmit side is reporting oversize frames.
Workaround: None.
Symptom: APS group is displayed as "not associated" in show aps detail command output.
Workaround: Do a shutdown/no shutdown command sequence to either or both interfaces in the APS group. This causes a state change of the interfaces. You can also perform a aps disable/aps enable command sequence to the APS group.
Symptom: Y-cable transponder protection does not come up as active after removing lockout.
Workaround: Perform a aps disable/aps enable command sequence to the APS group.
Symptom: With line card protection configured, the switch fabric on both the active CPU switch module and the standby CPU switch module are out of sync.
Workaround: Insert all the cards and perform a no connect command and then connect command.
Symptom: CDR loss of lock is not reported after Sysplex CLO/ETR encapsulation on a transparent interface.
Workaround: Perform a shutdown/no shutdown command sequence on the interface to correct the CDR loss of lock reporting.
Symptom: Tx-CRC and CDL-HEC error counters do not show the proper values in the show interfaces command output for the waveethernetphy interface.
Workaround: None.
Symptom: Wave interfaces see continuous flapping when the wavepatch interface on a nonsplitter card is shut.
Workaround: None.
Symptom: If two different trunk cards in the same slot are hot-swapped, the newly inserted trunk card inherits the configuration of the ethernetdcc interface from the removed trunk card.
Example: If a user swaps a 2.5-Gbps ITU trunk card with a 10-Gbps ITU trunk card in the same slot, the ethernetdcc interface for the newly inserted 10-Gbps ITU trunk card inherits the ethernetdcc interface configuration from the removed 2.5-Gbps ITU trunk card.
Workaround: None.
Symptom: Wavepatch interface configurations are retained when swapping a 10-Gbps ITU trunk card, 2.5-Gbps ITU trunk card, or transponder line card.
Workaround: None.
Symptom: Loss of connectivity via the ethernetdcc interface occurs when splitter protection is configured and the waveethernetphy interface is shut down while protection on the wavepatch is active and the working wavepatch is down.
Workaround: Do not shut down the waveethernetphy interface while the working wavepatch is down.
Symptom: If bidirectional nonrevertive splitter APS is configured on the 10-Gbps or 2.5-Gbps trunk cards, a simultaneous OIR of the local and remote cards might cause the APS to switch to protection wavepatch when the card comes up.
Workaround: Enable revertive mode if the working wavepatch comes up as Active.
Symptom: The PSM is incorrectly recognized as an OADM module by Cisco IOS images that do not support the PSM.
Workaround: Upgrade software to 12.1(12c)EV.
Symptom: When lockout on the protection path is removed with a signal failure on working, the splitter switches back and forth between protection and working on 2.5-Gbps and 10-Gbps splitter ITU trunk cards.
Workaround: None.
Symptom: While performing an OIR of a protection card in a y-cable configuration, the local and remote working port is flooded with CRC errors.
Workaround: Disconnect the standby branch of the y-cable during standby line card or SFP insertion.
Symptom: 10-Gbps ITU trunk cards fail during power-on diagnostics at the Quadphy loopback test (qphy-fabric-lb).
Workaround: None.
Symptom: Traffic loss of 30-45 seconds might occur when a y-cable APS configuration with protection switchover is used with the Catalyst 6000 family.
Workaround: Disable auto-negotiation and enable debounce timer with 100-ms delay on Catalyst 6000 family using the set port debounce mod/port enable command sequence.
Symptom: Update alarms and add new alarms for new cards.
Workaround: None.
Symptom: Controller type for the backplane is not displayed in the show hardware detail command output.
Workaround: None.
Symptom: The following problems might occur on 8-port FC/GE aggregation cards:
- The interface is missing from the running-configuration after the insertion of SFP. The system message for the insertion will not be printed to the console.
- The interface is present in the running-configuration after the removal of SFP. The system message for the removal will not be printed to the console.
Workaround: OIR the 8-port FC/GE aggregation card to recover from the problematic state.
Symptom: The show optical filter command output shows invalid information regarding the interface wavelength for filters.
Workaround: None.
Symptom: The system crashes when WB-VOA and PB-OE modules are removed.
Workaround: None.
Symptom: If the primary CPU switch module crashes due to a send break after executing POD and before booting the system image completely, the new primary CPU switch module comes up in Cisco IOS with junk entries programmed in the SII lookup tables of the 10-Gbps ITU trunk cards present in the chassis. As a result, all 10-Gbps ITU trunk cards are stuck in the decoder and the floating channels are enabled.
Workaround: None.
Symptom: Transmit failure is cleared before APS is notified of failure and does not take correct action.
Workaround: Issue a shutdown/no shutdown command sequence on the interface.
Symptom: Disconnecting a 10-port ESCON or 8-port FC/GE aggregation card from a 2.5-Gbps ITU trunk card can cause two ports to have the same flow identifier.
Workaround: Avoid assigning the same flow identifier to the ports in the portgroup.
Symptom: The gt-interrupt and interrupt0 tests on the CPU switch module fail.
Workaround: None.
Symptom: Because of the inability to synchronize the standby CPU switch module (with latest Cisco IOS image) has lower capabilities than the active processor (older EV4 image). The following alarm appears:
%CPU_REDUN-3-CAPABILITIES: Alarm: ASSERT, MINOR, PSC card 5, Standby with lower capabilitiesWorkaround: None.
Symptom: The WB-VOA module functional image version is different in the show hardware and show controllers command outputs.
Workaround: None.
Symptom: On a splitter APS switchover based on a CVRD SF condition, the SF threshold exceeded count is not incremented. There is also no log or event on the console that differentiates between switches overdue to CVRD SF or loss-of-lock.
Workaround: None.
Symptom: High alarm and low alarm status not cleared for WB-VOA or PB-OE modules when optical power is in a high warning or low warning state.
Workaround: None.
Symptom: When a new line card is inserted and the backplane connection does not happen properly or there is some other accessibility issue, the driver will see card access failure. But no alarm is raise to the Network Management station.
Workaround: None.
Symptom: A y-cable switchover from working to protection does not work. The show aps group command output shows that "auto fail over" is disabled and transmitting sf-lp from protection port.
Workaround: None.
Symptom: Removing the configured threshold for CDL HEC and CRC removes the template (and default values) resulting in CDL HEC and CRC errors.
Workaround: Apply a threshold group for CRC/CDLHEC from CLI and remove it.
Symptom: When removing a 2.5-Gbps ITU trunk card from the shelf, the following error message might appear:
%LC_2P5G-3-INTERNAL_CRITICAL: physubcard/idprom NULL in city_island_get_laser_frequencyWorkaround: None.
Symptom: After a CPU switch module switchover, sometimes ptopMIB and ptopoExtnMibs are not readable or settable through SNMP.
Workaround: The values can be read or set by using the CLI.
Symptom: When waveethernetphy interface on a 2.5-Gbps ITU trunk card with splitter APS configured is shutdown, loss-of-lock and loss-of-sync alarms are reported in the output of the show facility-alarm status command.
Workaround: None.
Symptom: A fan tray removal does not trigger any alarms.
Workaround: None.
Symptom: If ESCON data traffic is mixed with Gigabit Ethernet traffic cross connected to the same 10-GE ITU trunk card, ESCON traffic experiences errors. Ports on the ESCON director might not even come up.
Workaround: Assign valid flow identifiers to all 10 ports on the ESCON aggregation card.
Symptom: Currently the Tx-buffer configuration is allowed on the port group interface on ESCON. This CLI has to be moved to the client interface.
Workaround: Configure the CLI from the portgroup interface on the ESCON card.
Symptom: OFC (open fibre control) is not supported with Fibre Channel on the 8-port FC/GE aggregation card. The link might not initialize if an 8-port FC/GE aggregation card is used with older Fibre Channel equipment that employ OFC laser safety mechanisms.
Workaround: None.
Limitations and Restrictions
This section provides limitations and restrictions for Cisco ONS 15530 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.
CPU Switch Modules
This section contains limitations and restrictions that apply to transponder modules.
