Control-Plane Failover
Control-plane failover is the process of the standby RPM becoming the primary RPM.
The system automatically fails over to the standby RPM when:
1 Communication is lost between the standby and primary RPM.
2 You remove the primary RPM.
You can perform a manual failover by entering the redundancy force-failover rpm command.
To display the reason for the last control-plane failover on the chassis, enter the show redundancy
command in EXEC Privilege mode.
