Introduction

The Cisco ONS 15540 ESP is an optical transport platform that employs DWDM (dense wavelength division multiplexing) technology. With the Cisco ONS 15540 ESP, users can take advantage of the availability of dark fiber to build a common infrastructure that supports data, SAN (storage area networking), and TDM (time-division multiplexing) traffic. For more information about DWDM technology and applications, refer to the Introduction to DWDM Technology publication and the
Cisco ONS 15540 ESP Planning Guide.

Caveats

This section describes open and resolved severity 1 and 2 caveats and certain severity 3 caveats. The "Open Caveats" section lists open caveats that apply to the current release and may apply to previous releases. The "Resolved Caveats" sections list caveats resolved in a particular release, but open in previous releases.

Resolved Caveats in Release 12.2(23)SV1

CSCef68324

Cisco Internetwork Operating System (IOS) software is vulnerable to a Denial of Service (DoS) and potentially an arbitrary code execution attack from a specifically crafted IPv6 packet. The packet must be sent from a local network segment. Only devices that have been explicitly configured to process IPv6 traffic are affected. Upon successful exploitation, the device may reload or be open to further exploitation.

Cisco has made free software available to address this vulnerability for all affected customers.

More details can be found in the security advisory that is posted at http://www.cisco.com/warp/public/707/cisco-sa-20050729-ipv6.shtml.

Open Caveats in Release 12.2(23)SV

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, reset the active processor card or switch to the standby processor card, and reenter the patch commands.

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.

CSCed74239

Symptom: In a point-to-point network with y-cable based APS configured, the protection path does not automatically come up if the working path is down.

Workaround: Put a loopback on the client side to restore traffic to the protection path.

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: Disable and then enable laser safety control again to bring up the OSC wave interface.

CSCec28182

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

Workaround: None.

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 CPU 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 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.

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 is unable 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 CPU and keep the active CPU in the ROM monitor (ROMMON) mode for a long time, the standby CPU 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.
