    Display SSB Mastership from the Command Line

    Purpose

    To determine SSB mastership from the command line.

    Action

    To display more detailed SSB status information, use the following command:

    user@host> show chassis ssb

    Sample Output

    user@host> show chassis ssb
    SSB status:
      Failover:                      0 time
      Slot 0:
        State:                         Master
        Temperature:                33 Centigrade
        CPU utilization:             0 percent
        Interrupt utilization:       0 percent
        Heap utilization:            0 percent
        Buffer utilization:          6 percent
        DRAM:                       64 Mbytes
        Start time:                    1999-01-15 22:05:36 UTC
        Uptime:                        21 hours, 21 minutes, 22 seconds
      Slot 1:
        State:                         Backup 
    

    Meaning

    The command output displays the number of times the mastership has changed, the SSB slot number 0 or 1, and the current state of the SSB: Master, Backup, or Empty. The command output displays the temperature of the air passing by the SSB, in degrees Centigrade. It also displays the total percentage of CPU, interrupt, heap space, and buffer space being used by the SSB processor, including the total DRAM available to the SSB processor. The command output displays the time when the SSB started running and how long it has been running.
