Command History
Usage Guidelines When a user enables the issu runversion command, a switchover is performed, and the standby RP is
booted with the old image version following the reset caused by the switchover. As soon as the standby
RP moves into the standby state, the rollback timer is started.
Examples In the following example, the issu runversion command is used to switch to the redundant RP with the
new Cisco IOS software image:
Router# issu runversion b stby-disk0:c10k2-p11-mz.2.20040830
