Checking the Routing Engine Status

This section provides a brief description of monitoring the Routing Engines as part of the host subsystem on the T320 router and T640 routing node. For more detailed information about monitoring the Routing Engine, see Monitoring the Routing Engine.

Action

To check the Routing Engine status, use the following CLI 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

    Memory utilization          11 percent

    CPU utilization:

      Background                 0 percent

      Kernel                     5 percent

      Interrupt                  1 percent

      Idle                      94 percent

    Model                          RE-4.0

    Serial ID                      P11123900322

    Start time                     2004-09-25 19:32:31 PDT

    Uptime                        9 days, 20 hours, 53 minutes, 8 seconds

    Load averages:                 1 minute   5 minute  15 minute

                                       0.00       0.00       0.00

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:

What It Means

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.

Alternative Actions

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