    Displaying FPC Error Messages in the System Log File

    Purpose

    Gather FPC error messages from the system log file.

    To determine the details of the FPC error messages in the system log file.

    Action

    To check for FPC error messages in the system log messages file, use the following command:

    user@host> show log messages | match fpc

    Check for error messages at least 5 minutes before and after an FPC alarm occurs.

    Sample Output

    The following output displays when you browse through the messages log file using the time and date stamp to look for error messages that occur 5 minutes before and after the FPC event:

    user@host>  show log messages

    Mar 10 09:20:38 cls-edge-02 ssb PFEMAN: closing FPC 1 socket 
    Mar 10 09:20:42 cls-edge-02 ssb PFEMAN: FPC socket closure indicated 
    Mar 10 09:20:42 cls-edge-02 ssb PFEMAN: close on unlisted socket, 0xb0e200
    

    The following output displays when you use the | match filter command to look for specific information in the messages log file:

    user@host>  show log messages | match fpc

    Mar 31 05:13:48 bopper chassisd[630]: CHASSISD_FRU_UNRESPONSIVE: FPC 5 unresponsive, setting offline!
    

    Meaning

    When an FPC fails, the System and Switch Board (SSB), System Control Board (SCB), and Switching and Forwarding Modules (SFMs) generate error messages. The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. Use the show log messages | match fpc command to view only FPC error messages. Use this information to diagnose an FPC problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events prior to the FPC problem. For more information about system log messages, see the Junos OS System Log Messages Reference .
