    Monitoring the SIB Status

    To monitor the SIB status:

    1. Displaying the SIB Summary Status
    2. Displaying the SIB LED Status at the Command Line
    3. Check the SIB LED Status on the Faceplate
    4. Displaying the SIB Environmental Status

    Displaying the SIB Summary Status

    Purpose

    To obtain the SIB summary status.

    Action

    To display the SIB summary status, use the following command:

    user@host> show chassis sibs

    Sample Output

    t640@host>  show chassis sibs
    Slot  State               Uptime
     0    Spare
     1    Online             4 hours, 5 minutes, 47 seconds
     2    Online             4 hours, 5 minutes, 42 seconds
     3    Online             4 hours, 5 minutes, 37 seconds
     4    Online             4 hours, 5 minutes, 33 seconds 
    

    Meaning

    The command output displays the SIB slot number: 0, 1, 2, 3, and 4. The output also displays the operating status of each SIB as Online, Offline, or Empty, and how long each SIB has been online.

    Displaying the SIB LED Status at the Command Line

    Purpose

    To obtain the SIB LED status at the CLI.

    Action

    To display the SIB LED status, use the following command:

    user@host> show chassis craft-interface

    Sample Output

    t640@host>  show chassis craft-interface
    [...Output truncated...]
    SIB LEDs:
      SIB  0   1   2   3   4
    --------------------------
    Red    .   .   .   .   .
    Green  *   *   *   *   * 
    

    Meaning

    The command output is for a T640 router. Asterisks (*) represent the operating state. The status colors represent the possible SIB operating states: Red (Fail) and Green (OK). All SIBs are functioning normally.

    Check the SIB LED Status on the Faceplate

    Purpose

    To check the SIB LED status on the faceplate.

    Action

    To check the SIB LED status, remove the component cover and look on the SIB faceplate at the back of the T320 router and the T640 router.

    Table 1 describes the SIB LED states.

    Displaying the SIB Environmental Status

    Purpose

    To display the SIB environmental status.

    Action

    To display the SIB environmental information, use the following command:
