Verifying That Graceful Routing Engine Switchover Is Working in the Virtual Chassis

Purpose

Verify that a Graceful Routing Engine switchover (GRES) between two member switches acting as the master and backup routing engines in a Virtual Chassis has occurred.

Action

On the master switch, verify the member ID of the backup Routing Engine:

  1. Connect to the backup Routing Engine:

  2. Verify that the backup Routing Engine is ready for switchover on member ID 1:

  3. Switch the current backup Routing Engine to master Routing Engine:

    Note:

    You must wait a minimum of two minutes between Routing Engine failovers for the Routing Engines to synchronize.

  4. Verify that the master and backup Routing Engines have switched roles:

    Note:

    Member ID 1 is now the master and member ID 0 is now the backup.

Meaning

With graceful Routing Engine switchover enabled, when you initiated a switchover from the backup Routing Engine, the backup Routing Engine became the master and the master Routing Engine became the backup.
