    Checking the Routing Engine Status

    Purpose

    To monitor the Routing Engines as part of the host subsystem on the T320 router and T640 router. For more detailed information about monitoring the Routing Engine, see Checklist for Monitoring the Routing Engine.

    Action

    To check the 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:
        Current state                  Master
        Election priority              Master (default)
        Temperature                 28 degrees C / 82 degrees F
        CPU temperature             27 degrees C / 80 degrees F
        DRAM                      2048 MB

    Routing Engine status:
      Slot 1:
        Current state                  Backup
        Election priority              Backup (default)
        Temperature                 29 degrees C / 84 degrees F
        CPU temperature             30 degrees C / 86 degrees F
        DRAM                      2048 MB
        Memory utilization          10 percent
        CPU utilization:
    [...Output truncated...]
    

    Meaning

    The command output displays the Routing Engine slot number, current state (Master, Backup, or Disabled), election priority (Master or Backup), and airflow temperature. The command output also displays the total DRAM available to the Routing Engine processor, the CPU utilization percentage, and the Routing Engine serial number for the slot. Additionally, the command output displays when the Routing Engine started running, how long the Routing Engine has been running, and the time, uptime, and load averages for the last 1, 5, and 15 minutes.

    Check the Uptime to ensure that the Routing Engine has not rebooted since it started running.

    To check the Routing Engine environmental status information, such as the operating state, function, and operating temperature, use the following command:

    user@host> show chassis environment routing-engine
    Routing Engine 0 status:
      State                           Online Master
      Temperature                  28 degrees C / 82 degrees F
    Routing Engine 1 status:
      State                           Online Standby
      Temperature                  29 degrees C / 84 degrees F
    

    Check the LCD display on the craft interface to view information about the router temperature and the status of the Routing Engines.
