Verifying HCM Failure

Action

To view current HCM status when the backup Routing Engine takes over, use the following CLI command.

user@host> show chassis routing-engine

Sample Output

user@host> show chassis routing-engine

What It Means

The Routing Engine in slot RE0 and companion HCM in slot HCM0 are backup. The Routing Engine in slot RE1 and companion HCM in slot HCM1 are master.

Alternative Method

To verify an HCM failure, you can also use the following CLI command:

user@host> show chassis environment hcm

Sample Output

user@host> show chassis environment hcm 

HCM 0 status:

  State                           Offline

  FPGA Revision                27

HCM 1 status:

  State                           Online Master

  FPGA Revision                27

What It Means

The HCM in slot HCM0 is offline. The HCM in slot HCM1 has taken over as master.
