    Display SIB Redundancy Information

    Purpose

    To gather information about the redundant SIB.

    Action

    Use the following command:

    user@host> show chassis sib

    Sample Output

    t320@host> show chassis sibsSlot  State               Uptime
     0    Spare           
     1    Online             2 days, 7 hours, 10 minutes, 13 seconds
     2    Online             2 days, 7 hours, 10 minutes, 13 seconds
    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 is for a T320 router, T640 router, T1600 router, TX Matrix, and TX Matrix router. On the T320 router, SIB1 and SIB2 are active (Online), while SIB0 is backup (Spare). On the T640 router and the T1600 router, SIB1, SIB2, SIB3, and SIB4 are active, while SIB0 is the backup. The possible states are Spare, Online, Offline, or Empty. The command output also displays how long each SIB has been online in hours, minutes, and seconds.

    You can also view redundant SIB status by using the following command:

    user@host> show chassis environment sib
    user@host> show chassis environment sib
    SIB 0 status:
      State                           Spare
      Temperature                  44 degrees C / 111 degrees F
      Power:
        GROUND                      0 mV
        1.8 V                    1807 mV
        2.5 V                    2478 mV
        3.3 V                    3308 mV
        1.8 V bias               1797 mV
        3.3 V bias               3284 mV
        5.0 V bias               5018 mV
        8.0 V bias               7440 mV
    SIB 1 status:
      State                           Online
      Temperature                  50 degrees C / 122 degrees F
      Power:
        GROUND                      0 mV
        1.8 V                    1814 mV
        2.5 V                    2485 mV
    1.8 V bias               1794 mV 
        3.3 V bias               3313 mV
        5.0 V bias               5028 mV
        8.0 V bias               7553 mV
    SIB 2 status:
      [...Output truncated...]
    SIB 3 status:
      [...Output truncated...]
    SIB 4 status:       
      [...Output truncated...]
    

    The command output displays the SIB slot, status, and the temperature of the air flowing past the SPP card and the power source information. Notice that SIB0 status is displayed as Spare, or backup.

    You can display the environmental status of a particular SIB with the following command:

    user@host> show chassis environment sib slot
