How to Perform the ISSU Process
This example shows how to reset and reload the current standby supervisor engine (slot 1) with the new
Cisco IOS XE software version. After you enter the commitversion command, the standby supervisor
engine boots in the Standby Hot state.
Switch> enable
Switch# issu commitversion 5 slavebootflash:new_image
%issu commitversion executed successfully
Use the following to verify that the standby supervisor engine is reloaded with the new software.
Switch# show redundancy states
Redundancy Mode (Operational) = Stateful Switchover
Redundancy Mode (Configured) = Stateful Switchover

Communications = Up

client count = 64

client_notification_TMR = 240000 milliseconds
