    Monitor the HCM Status

    To monitor the HCM status:

    1. Check HCM LEDs
    2. Check HCM Environmental Status
    3. Check the Companion Routing Engine Status

    Check HCM LEDs

    Purpose

    To monitor the HCM status by checking the HCM LEDs on the component faceplate.

    Action

    To check the HCM LEDs, look at the component faceplate at the bottom left front of the M10i router chassis (see Table 1).

    Two LEDs indicate HCM status—a green PWR LED and a blue MSTR LED. describes the LED states.

    Description

    PWR

    Green

    On steadily

    HCM is functioning normally

     

    Blinking

    HCM is starting up.

    MSTR

    Blue

    On steadily

    HCM is master.

    Check HCM Environmental Status

    Purpose

    To isolate problems in the HCM by checking the environmental status.

    Action

    To check the HCM environmental status, use the following command:

    user@host> show chassis environment hcm

    Sample Output

    user@host> show chassis environment hcm
    HCM 0 status:
    			 State 												Online Master
    			 FPGA Revision 								27
    		 HCM 1 status:
    			State 												Present Standby
    			FPGA Revision 									27

    Meaning

    The command output shows that the HCM status, including slot number, operating state, and field programmable gate array (FPGA) revision.

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

    m10i@host> show chassis environment hcm slot

    Check the Companion Routing Engine Status

    Purpose

    The HCM in the slot labeled HCM0 is paired with the Routing Engine in the slot labeled RE0. Likewise, the HCM in the slot labeled HCM1 is paired with the Routing Engine in the slot labeled RE1. By default, the HCM in the slot labeled HCM0 is the master.

    When HCM mastership changes because of failure, Routing Engine mastership changes as well.

    Action

    To check Routing Engine status, use the following command:

    user@host>show chassis routing-engine

    Sample Output

    user@host>show chassis routing-engine
    Routing Engine status:
     Slot 0:

    Meaning

    The command output displays the operating state of both Routing Engines installed in the router chassis, including slot number, current state, and default election priority—master or backup. The command output also displays the Routing Engine temperature, amount of memory, and the percentage of memory and CPU utilization. The command output displays the Routing Engine model number, serial number ID, start time, and total operating time.

    Look at the Routing Engine LEDs by using the show chassis routing-engine command or by looking at the component faceplate at the front of the router. The Routing Engine has four LEDs that tell operating status: a green LED labeled HDD, a blue LED labeled MASTER, a red LED labeled FAIL, and a green LED labeled ONLINE. Table 2 describes the Routing Engine LED states.
