    Monitor the Control Board Status

    To check the Control Board status:

    1. Check the Control Board Environmental Status
    2. Check the Control Board Status from the Craft Interface

    Check the Control Board Environmental Status

    Purpose

    To check the Control Board environmental status for each Control Board installed in the router chassis.

    Action

    To check the Control Board environmental status, use the following command:

    user@host> show chassis environment cb

    Sample Output

    t640@host>  show chassis environment cb
    CB 0 status:
      State                           Online Master

    Meaning

    The command output lists the Control Board state, redundancy status, temperature, power supply voltages, and circuitry revision level. If you do not specify a Control Board slot number, the command displays the environmental status for each Control Board installed in the router chassis. If you specify a Control Board slot number, the command displays the status for that slot only.

    Check the Control Board Status from the Craft Interface

    Purpose

    To check the Control Board status from the craft interface.

    Action

    To check the Control Board status from the craft interface, use the following command:

    user@host> show chassis craft-interface

    Sample Output

    t640@host>  show chassis craft-interface
    FPM Display contents:
    [...Output truncated...}
    CB LEDs:
      CB   0   1
    --------------
    Amber  .   .
    Green  *   *
    Blue   *   .
    [...Output truncated...]
    

    Meaning

    The sample output shows that the routing platform has two Control Boards online and functioning normally. The Control Board installed in slot 0 is functioning as master. If an yellow asterisk displays, the Control Board has failed.

    To view the Control Board status, you can do one of the following:

    • (T320, T640, T1600, and TX Matrix router) Look at the router craft interface host module status or look at the LCD display for any Control Board alarms.

      Table 1 describes the T320, T640, and T1600 router host subsystem LED states.
