Periodic syslog messages for shutdowns due to fault-recovery failures

Want to summarize with AI?

Log in

Describes the periodic syslog messages the router generates when a card is shut down because of repeated fault-recovery failures, which repeat every 60 minutes until the operator manually recovers the card.


A periodic shutdown syslog message is a log message generated by the router when

  • the LC, FC, or RP experiences a fault,

  • the Cisco IOS XR software triggers the fault recovery cycle, attempting to reboot the LC, FC, or RP to restore operational status, and

  • if the LC, FC, or RP fails to become operational after this recovery attempt, the Cisco IOS XR software proceeds to shut down the affected component and generates a shutdown syslog message immediately after the shutdown.

Cisco IOS XR Software now generates a syslog message immediately to indicate its shutdown state after a Line Card (LC), Fabric Card (FC), or Route Processor (RP) shuts down due to fault-recovery failure. This syslog message is repeated every 60 minutes to keep you informed of the shutdown status.

This enhancement helps in identifying and troubleshooting shutdown LC, FC, or RP components.

*This feature is now supported on:

  • 8212-48FH-M

  • 8711-32FH-M

  • 88-LC1-12TH24FH-E

  • 88-LC1-36EH

  • 88-LC1-52Y8H-EM

By default, the Cisco IOS XR software performs the fault recovery cycle five times before shutting down the LC, FC, or RP. If the fault recovery handling count is configured, the Cisco IOS XR software shuts down the LC, FC, or RP after the expiry of the fault recovery count. For more information, refer to Fault recovery handling.

Before Release 24.4.1, the Cisco IOS XR software generates a shutdown syslog message only once immediately after the LC, FC, or RP shut down to notify you of the shutdown.

From Release 24.4.1 onwards, the Cisco IOS XR software generates this shutdown syslog message immediately after the LC, FC, or RP shuts down and repeats the shutdown syslog message every 60 minutes to notify you of the shutdown until you manually shut down the LC, FC, or RP using the hw-module shutdown location or reload location commands.

Router: Dec 4 15:44:22.950 PST: shelfmgr[121]: %PLATFORM-SHELFMGR-2-FAULT_ACTION_CARD_SHUTDOWN : Forced shutdown requested for card 0/FC0. Reason Fault retry attempts exceeded configured count(1)
Router:Dec 4 15:44:25.247 PST: shelfmgr[121]: %PLATFORM-SHELFMGR-4-CARD_SHUTDOWN : Shutting down 0/FC0: Fault retry attempts exceeded configured count(1)

Limitations and restrictions for periodic shutdown syslog messages

When you manually shut down a specific node using the shutdown location command in XR EXEC mode or the hw-module shutdown location command in XR Config mode, the Cisco IOS XR software doesn't generate the shutdown syslog messages.
