    Check the Redundant Control Board Status from the Craft Interface

    Purpose

    To obtain the status of the redundant Control Board.

    Action

    If you are near the router, physically look at the craft interface for the Control Board LEDs. To display redundant 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 CB LEDs section of the command output indicates the status of the redundant Control Board. An asterisk (*) indicates the current operating state: Amber (offline), Green (online), and Blue (Master). In the above output, no redundant Control Board is installed—the output under CB1 is blank.
