Executing a hitless stacking switchover

The following must be in effect before a hitless switchover (to the standby controller) is allowed:
• Hitless stacking is enabled.
• The stack has a standby controller.
• The standby controller has learned the protocols.
• The standby controller has the same priority as the active controller.
• More than 120 seconds have passed since the previous switchover or failover.
You can use the show stack command to check these criteria.
To perform a switchover, enter the following command.
device# stack switch-over
Standby unit 8 will become active controller, and unit 1 will become standby
Are you sure? (enter 'y' or 'n'): y
Unit 1 is no longer the active controller
