    Check the Redundant Control Board Environmental Status


    To obtain the environmental status of the redundant Control Board.


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

    user@host> show chassis environment cb

    Sample Output

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

    The command output displays which Control Board is master and standby. Additionally, the command output displays the Control Board state, redundancy status, temperature, power source, and circuitry revision level for each Control Board installed in the router chassis. CB1 is shown in standby mode, and is the redundant Control Board.

    To display the environmental status of a particular Control Board, use the following command:

    t640@host> show chassis environment cb slot
