    Monitor the CFEB Status

    To monitor the CFEB status:

    1. Display the CFEB Environmental Status
    2. Display the CFEB Detailed Status
    3. Check CFEB LEDs

    Display the CFEB Environmental Status

    Purpose

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

    Action

    To display the CFEB environmental status, use the following command:

    user@host> show chassis environment

    Sample Output

    user@m5-host> show chassis environment
    Class Item                   Status     Measurement
    Power Power Supply 0         OK
          Power Supply 1         Absent
    Temp  Intake                 OK         22 degrees C / 71 degrees F
          FPC 0                  OK         23 degrees C / 73 degrees F
          Power Supplies         OK         23 degrees C / 73 degrees F
          CFEB Intake            OK         24 degrees C / 75 degrees F
          CFEB Exhaust           OK         30 degrees C / 86 degrees F
    [...Output truncated...]
    

    Meaning

    The command output displays the temperature and status of the CFEB intake and exhaust, which can be OK, Failed, or Absent.

    Display the CFEB Detailed Status

    Purpose

    To obtain a more detailed status of the CFEB.

    Action

    To display more detailed CFEB status, use the following command:

    user@host> show chassis cfeb

    Sample Output

    user@host> show chassis cfeb
    CFEB status:
    Slot 0 information:
      State                                 Master
      Intake temperature                 29 degrees C / 84 degrees F
      Exhaust temperature                38 degrees C / 100 degrees F
      CPU utilization                     3 percent
      Interrupt utilization               0 percent
      Heap utilization                   10 percent
      Buffer utilization                 22 percent
      Total CPU DRAM                    128 MB
      Internet Processor II                 Version 1, Foundry IBM, Part number 164
      Start time:                           2004-09-28 03:07:54 PDT
      Uptime:                              9 days, 18 hours, 36 minutes, 15 seconds
    Slot 1 information:
      State                                 Backup
    

    Meaning

    The command output displays the temperature of the air passing by the CFEB intake and exhaust, in degrees Centigrade. It displays the total percentage of CPU, interrupt, heap space, and buffer space being used by the CFEB processor, including the total DRAM available to the CFEB processor. The command output displays the time when the CFEB started running and how long the CFEB has been running. A short uptime can indicate that there is a CFEB problem.

    Check CFEB LEDs

    Purpose

    Three LEDs—a green LED labeled OK, a red LED labeled FAIL, and a blue LED labeled MASTER—indicate CFEB status.

    Action

    Look at the LEDs on the CFEB faceplate. The CFEB is located on the rear of the router above the power supplies (see CFEB Overview). Table 1 describes the CFEB LED states.

    FAIL

    Red

    On steadily

    CFEB is not operational or is in reset mode.

    MASTER

    Blue

    On steadily

    CFEB is functioning as master.
