Forcing a Switchover from the Active RP to the Standby RP: Example
At this point, the system is ready to switch over and run the new version of Cisco IOS software that has
been loaded onto the standby RP. When you enter the issu runversion command, an SSO switchover
will be performed, and NSF procedures will be invoked if so configured.
Router# issu runversion b stby-disk0:c10k2-p11-mz.2.20040830
Once the ISSU process has been completed, the system will be running the new version of software and
the previously active RP will now become the standby RP. The standby will be reset and reloaded, but it
will remain on the previous version of software and come back online in STANDBY-HOT status. The
following example shows how to connect to the newly active RP and verify these conditions.
