During a switchover, system control and routing protocol execution are transferred from the active to the standby CPM.

A manual switchover may occur under the following conditions:
To force a switchover from an active CPM to a standby, use the admin redundancy force-switchover command. You can also use the config system switchover-exec and admin redundancy force-switchover now CLI commands to configure a batch file that runs after a failover.
