    Action

    To display the SIB error messages in the system log file, use the following command:

    user@host> show log messages | match sib

    Sample Output

    ser@host> show log messages | match sib
    SIB_STATE_OFFLINE_ACK_WAIT
    Jan 29 18:37:09 toto spmb0 CMGSIB: SIB #2 state transition SIB_STATE_OFFLINE_AC
    K_WAIT -> SIB_STATE_OFFLINE

    IB_STATE_ONLINE_WAIT

    Meaning

    The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. You can also use the show log messages | match sib command to see error messages that are generated when a SIB fails or is offline. Use this information to diagnose a SIB problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events that occurred before and after the problem. For more information about system log messages, see the Junos OS System Log Messages Reference.

    Display SIB Error Messages in the Chassis Daemon Log File

    Purpose

    To determine the details of the SIB error messages in the chassis daemon log file. The chassis daemon (chassisd) log file keeps track of the state of each chassis component.

    Action

    To display the SIB error messages logged in the chassis daemon log file, use the following command:

    user@host> show log chassisd | match sib

    Sample Output

    user@host> show log chassisd | match sib
    cli command

    Meaning

    The chassisd database provides the date, time, and a component status message. The chassisd database is dynamic. It is initialized at router startup and is updated when components are added or removed. You can search for multiple items in the chassisd log file by using the | match sib command to see error messages that are generated when a SIB fails or is offline. Use this information to diagnose a SIB problem and to let JTAC know what error messages were generated and the router events that occurred before and after the problem. For more information about system log messages, see the Junos OS System Log Messages Reference.
