CPM Switchover
During a switchover, system control and routing protocol execution are transferred from the active
to the standby CPM.
An automatic switchover may occur under the following conditions:
• A fault condition that causes the active CPM to crash or reboot.
• The active CPM is declared down (not responding).
• Online removal of the active CPM.
A manual switchover can 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 configure a batch file that executes after
failover by using the config system switchover-exec and admin redundancy force-
switchover now CLI commands.
