436 ! Monitoring the HCM Status
Step 3: Check the Companion Routing Engine Status
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 CLI command:
user@host> show chassis routing-engine
Sample Output user@host> show chassis routing-engine

What It Means 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.
