Example: Forcing the Router to Switch from Primary Line Module to Spare Line Module
In the following example, the user forces the router to switch from the primary line module to the spare line module by issuing the redundancy force-switchover command. In the example, you first issue the show redundancy command to display redundancy information specific to line modules. You can then issue the redundancy force-switchover command to force the router to switch from the primary line module to the spare line module. To view the status of the line modules after the switchover, you can again issue the show redundancy command.
- Display the redundancy information.
