your Cisco router. Prerequisites Requirements Cisco recommends that you read Troubleshooting Router Crashes before proceeding with this document. Components Used The information in this document is based on these software and hardware versions: All Cisco IOSĀ® software versions All Cisco routers Note:This document does not apply to Cisco Catalyst switches or MGX platforms. The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Conventions Refer to the Cisco Technical Tips Conventions for more information on document conventions. Identifying Bus Error Crashes The system encounters a bus error when the processor tries to access a memory location that either does not exist (a software error) or does not respond properly (a hardware problem). A bus error can be identified from the output of the show version command provided by the router if not power-cycled or manually reloaded. If you have the output of a show version or show tec

received and reported in the system log (syslog). This section describes these messages. When a CSM-S is out of service, the module still replies to ARP requests but will not reply to pings. System Messages This section http://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-121-mainline/7949-crashes-buserror-troubleshooting.html lists the system log (syslog) messages supported in the CSM-S. The SSL daughter card will also generate system messages. The log levels are the same as those shown for the CSM. Note The SSL daughter card messages have a prefix of "STE" instead of "CSM_SLB." The Cisco IOS software message logs contain the warning level with this syntax: CSM_SLB_level-code TableC-1 lists the level codes. TableC-1 Error Message Level Codes Message Level Code LOG_EMERG 0 http://www.cisco.com/c/en/us/td/docs/interfaces_modules/services_modules/csms/1-1-1/configuration/guide/sysmsgs.html /* system is unusable */ LOG_ALERT 1 /* action must be taken immediately */ LOG_CRIT 2 /* critical conditions */ LOG_ERR 3 /* error conditions */ LOG_WARNING 4 /* warning conditions */ LOG_NOTICE 5 /* normal but signification condition */ LOG_INFO 6 /* informational */ LOG_DEBUG 7 /* debug-level messages */ When syslog messages are received, they are preceded by one of the following banners (where # is the slot number of the CSM-S module): Error Message CSM_SLB-3-IDB_ERROR Unknown error occurred while configuring IDB Explanation The MFSC could not create the internal interfaces for the CSM-S. Recommended Action Either this version of the MFSC or the IDPROM were incorrectly programmed. Reprogram the MFSC or the IDPROM. Error Message CSM_SLB-3-OUTOFMEM Module [dec] memory error Explanation This a general memory problem of the control module. The memory problem may lead to more serious operational problems in the CSM-S if it persists. Recommended Action Run a memory check, or increase the memory size. Error Message CSM_SLB-3-PORTCHANNEL Portchannel allocation failed for module [dec] Explanation This problem occurs when there are more CSM-S modules inserted into the chassis than configured or the slot number where the module was inserted was higher than anticipated. Recommended Action Move the CSM-S module to a lower slot number to resolve the problem. Error Message CSM_SLB-3-RELOAD Module [dec] configuration reload faile

This document helps you to troubleshoot potential hardware issues with Cisco 2800 Series Routers. This document also provides information to help you identify which component causes a hardware failure. This depends on the type of error that the router experiences. Note:This document does not cover any software-related failures except for those that are often mistaken as hardware issues.
