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.System Requirements
This section describes the system requirements for Cisco IOS Release 12.2(18)SV and includes the following sections:
•
Memory Requirements
The DRAM memory configuration is 128 MB, which is the default for the Cisco ONS 15540 ESP.

Caveats
This section describes open and resolved severity 1 and 2 caveats and select 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.
Open Caveats in Release 12.2(18)SV
•
Symptom: Tracebacks related to CPU hog issues are seen when reprogramming the 2.5-Gbps transponder module functional image.
Workaround: None.
•
Symptom: When 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.
Resolved Caveats for Release 12.2(18)SV
•
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.

•
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.
•
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.
•
Symptom: In a point-to-point network topology setup where bidirectional PSM trunk fiber protection APS is configured, and the in-band message channel is configured for dcc and the controller type of the OADM filter is 0x1104 (4-channel OADM without OSC), APS is unable to track a valid ethernetDcc interface. Therefore the group cannot be associated.
Workaround: Do not configure in-band message channel as dcc for PSM APS if the corresponding OADM module does not have OSC ports (controller type 0x1104).
•
Symptom: Continuous optical performance monitoring alarms cause memory leaks that lead to bus error exceptions and an unexpected reload.
Workaround: None.
•
Symptom: Unable to disable APS group through SNMP. The console or telnet session hangs indefinitely configuration mode is entered after the SNMP set command.
Workaround: Do not disable the APS group through SNMP.
•
Symptom: The standby processor card crashes when bus error exceptions are reported at ipc_process_timeout, when doing a send "brk" from a Telnet session, to the active processor card.
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.
•
•
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.

Obtaining Technical Assistance
For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, the Cisco Technical Assistance Center (TAC) provides 24-hour-a-day, award-winning technical support services, online and over the phone. Cisco.com features the Cisco TAC website as an online starting point for technical assistance. If you do not hold a valid Cisco service contract, please contact your reseller.
Cisco TAC Website
The Cisco TAC website ( http://www.cisco.com/tac) provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The Cisco TAC website is available 24 hours a day, 365 days a year.
Accessing all the tools on the Cisco TAC website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a login ID or password, register at this URL:
http://tools.cisco.com/RPF/register/register.do
Opening a TAC Case
Using the online TAC Case Open Tool ( http://www.cisco.com/tac/caseopen) is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer.
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete listing of Cisco TAC contacts, go to this URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
