To switch immediately from the primary SRP module to the redundant SRP module, you
can use the redundancy force-switchover command or the srp switch command. You
can also configure the router to prompt you if the modules are in a state that could lead
to loss of configuration data or NVS corruption.
Switch from the primary SRP module to the redundant SRP module by doing either of
the following:
Issue the redundancy force-switchover command.
host1#redundancy force-switchover 5
Issue the srp switch force command.
host1#srp switch force

You can determine the redundancy state of line modules and SRP modules by examining
their status LEDs. See Table 4 on page 22 for a description of the LEDs functions. In
addition, if you issue the show version command, the state field for the slot that contains
the redundant SRP module indicates standby.
