Manual switchover

Describes how to force a manual switchover from the active route processor to the standby by running the redundancy switchover command or by reloading the active RP with the reload command.


If a standby RP is installed and ready for switchover, you can perform the switchover by using these commands:

  • The redundancyswitchover command

  • The reload command.

Manual switchover using the redundancy switchover command

You can force a manual switchover from the active RP to the standby RP by using the redundancyswitchover command.

If a standby RP is installed and ready for switchover, the standby RP becomes the active RP. The original active RP becomes the standby RP. In this example, partial output for a successful redundancy switchover operation is shown:

Router# show redundancy

  This node (0/RP0/CPU0) is in ACTIVE role
  Partner node (0/RP1/CPU0) is in STANDBY role
  Standby node in 0/RP1/CPU0 is ready

  Router# redundancy switchover
  Updating Commit Database.  Please wait...[OK]
  Proceed with switchover 0/RP0/CPU0 -> 0/RP1/CPU0? [confirm]
  Initiating switch-over.
  Router#
  
<Your 'TELNET' connection has terminated>

Manual switchover using the reload command

You can force a manual switchover from the active RP to the standby RP by reloading the active RP using the reload command. As active RP reboots, the current standby RP becomes active RP, and rebooting RP switches to standby RP.

Router# reload
Router#

In the earlier example, the Telnet connection is lost when the previously active RP resets. To continue management of the router, you must connect to the newly activated RP as shown in this example:

  Password: xxxxx

Router#
  

If the standby RP is not in the ready state, the switchover operation is not allowed. In this example, partial output for a failed redundancy switchover attempt is shown:

Router# show redundancy
