Step 1: Check the Detailed Routing Engine Status

Action

To display a detailed status of the Routing Engine, use the following JUNOS CLI operational mode 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 

 Temperature          41 C / 105 degrees F

  DRAM               765 Mbytes

    Kernel             0 percent

    Interrupt          0 percent

    Idle            100 percent

  Serial ID            39000004f8bdec01

  Start time            2000-01-04 22:02:58 UTC

  Uptime               14 hours, 45 minutes, 40 seconds

  Load averages           1 minute   5 minute  15 minute

  Serial ID                        f2000004f903a801

  Start time               2000-01-04 01:28:02 UTC

  Uptime                 20 hours, 38 minutes, 1 seconds

What It Means

The command output displays the Routing Engine slot number, current state (Master, Backup, or Disabled), election priority (Master or Backup), and the 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. 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

(For M7i, M10i, M40e, M160, M320, and T320 routers and the T640 routing node) To check the status and temperature of the Routing Engines, use the following CLI command:

user@host> show chassis environment routing-engine

user@host> show chassis environment routing-engine

Route engine 0 status:

  State:                      Present Master

  Temperature:              0 degrees C / 32 degrees F

Route engine 1 status:

  State:                      Present

The command output displays the Routing Engine slot number, operating state, temperature, and whether it is operating as the master or backup. The state can be Present or Absent.

To check the status and temperature of a particular Routing Engine, use the following CLI command:

user@host> show chassis environment routing-engine slot
