    Monitoring Redundant MCS Status

    To monitor redundant MCSs, do one of the following:

    1. Check the Redundant MCS Environmental Status
    2. Check the Redundant MCS Status from the Craft Interface
    3. Check the Redundant MCS LED Status

    Check the Redundant MCS Environmental Status

    Purpose

    To determine the environmental status of the redundant MCS from the command line.

    Action

    To check the redundant MCS status, use the following command:

    user@host> show chassis environment mcs

    Sample Output

    user@host> show chassis environment mcs
    MCS 0 status:
      State                           Online Master
      Temperature                   0 degrees C / 32 degrees F
      Power:
        3.3 V                    3318 mV
        5.0 V                    5001 mV
        12.0 V                  11833 mV
        5.0 V bias               4991 mV
        8.0 V bias               8341 mV
      CMB Revision                 12
      FPGA Revision                12
    MCS 1 status:
      State                           Present
      Power:
        3.3 V                    3308 mV
        5.0 V                    5013 mV
        12.0 V                  11809 mV
        5.0 V bias               4952 mV
        8.0 V bias               8346 mV
      CMB Revision                 12 
    

    Meaning

    The show chassis environment mcs command is available on the M40e and M160 routers only. The command output displays environmental information about both MCSs installed in the router or about an individual MCS. The MCS status can be Present, Online, Offline, or Empty. The command also indicates that the MCS is the master MCS. The command output also displays the temperature of the air flowing past the MCS, information about MCS power supplies, field-programmable gate array (FPGA) revision information, and the revision level of the chassis management bus (CMB) backup.

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

    user@host> show chassis environment mcs slot

    Check the Redundant MCS Status from the Craft Interface

    Purpose

    To determine the status of the redundant MCS from the craft interface.

    Action

    To display redundant MCS status from the craft interface, use the following CLI command:

    user@host> show chassis craft-interface

    Sample Output

    user@host> show chassis craft-interface

    Meaning

    The MCS LEDs section of the command output indicates the status of the redundant MCSs. An asterisk (*) indicates the current operating state: Amber (offline), Green (online), and Blue (Master).

    Check the Redundant MCS LED Status

    Purpose

    To verify the LED status of the redundant MCS.

    Action

    To check redundant MCS LED status, look on the faceplate of the MCS at the rear of the router. Table 1 describes the LED states.

    State

    Description

    Blue

    MASTER

    On steadily

    MCS is master.

    Green

    OK

    On steadily

    MCS is operating normally.

    Blinking

    MCS is starting up.

    Amber

    FAIL

    On steadily

    MCS has failed.

    When the MCS is functioning normally, the green OK LED remains on steadily.
