Open Caveats in Release 12.2(18)SV
•CSCdu53656
A Cisco device running IOS and enabled for the Border Gateway Protocol (BGP) is vulnerable to a Denial of Service (DOS) attack from a malformed BGP packet. The BGP protocol is not enabled by default, and must be configured in order 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, please refer to this advisory, available at http://www.cisco.com/warp/public/707/cisco-sa-20040616-bgp.shtml.
•CSCdz59146
Symptom: The ethernetdcc interface loses connectivity 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.
•CSCdz64021
Symptom: While performing an online removal and insertion of a protection card in a y-cable configuration, the local and remote working ports are flooded with CRC errors.
Workaround: Disconnect the standby branch of the y-cable configuration during the insertion of the standby line card or SFP optics.
•CSCea28131

•CSCea52092
Symptom: After booting the system, power coming out of the OSC module seems to be null even though the laser is enabled.
Workaround: Perform an online removal and insertion of the OSC module or carrier motherboard.
•CSCeb18103
Symptom: The OSC wave interface does not come up when a trunk cable breaks and you configure laser safety control and trunk insertion.
Workaround: Disable and then enable LSC again to bring up the OSC wave interface.
•CSCec14447
Symptom: The 8-port GE/FC aggregation card laser is not in the proper state when a Tx-CRC threshold has been exceeded and FLC is configured.
Workaround: Issue the shutdown/no shutdown command sequence on the affected interface.
•CSCec42573
Symptom: In a y-cable APS configuration interfaces on the 8-port GE/FC aggregation card configured for FC/FICON encapsulation change to GE encapsulation when the saved configuration file is copied to the running configuration.
Workaround: Change the encapsulation back to FC/FICON.
•CSCin78329
Symptom: Power-on diagnostics may fail the credit-buffer-memory test for the 8-port FC/GE aggregation card on the first boot after power cycling the box. Subsequent reboots without power cycling pass the test. These test failures are spurious and can be ignored.
Workaround: Upgrade you Cisco ONS 15530 software to Cisco IOS Release 12.2(23)SV or later.
Resolved Caveats in Release 12.2(18)SV
•CSCdz89270
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.
•CSCeb19410
Symptom: An 8-port FC/GE aggregation card client interface laser may be off when it is configured in a disabled y-cable APS group.
Workaround: Enable then disable the APS group. This activates the client interface laser.
•CSCec03715
Symptom: If the flow identifier on an esconphy interface is changed without deleting the old flow identifier, both the old and the new flow identifiers are present in the lookup table of the ESCON aggregation card. As a result, the old flow identifier cannot be reused on this ESCON aggregation card.
Workaround: Perform an online removal and insertion of the ESCON aggregation card or issue the following sequence of commands in the interface configuration mode
1. no cdl flow identifier>
2. cdl flow identifier [OLD IDENTIFIER]
3. no cdl flow identifier
4. cdl flow identifier [NEW IDENTIFIER]
•CSCec34628
Symptom: Continuous optical power monitoring alarms cause memory leaks that lead to bus error exceptions and an unexpected reload.
Workaround: None.
Limitations and Restrictions
This section provides limitations and restrictions for Cisco ONS 15530 hardware and software.
Transponder Line Cards
This section contains limitations and restrictions that apply to transponder line cards.
•CRC errors might 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.
CPU Switch Modules
This section contains limitations and restrictions that apply to transponder modules.
•If both CPU switch modules are removed, all aggregation cards, OSC modules, transponder line cards, ITU trunk cards, and uplink cards are shut down.
Note Traffic on pass through optical channels (which passively pass through the OADM modules) are not affected by the removal of the processor cards.
