Command or Action
Step 3
Switch# show redundancy [states]
Step 4
Switch# show issu state [detail]
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
Switch# show issu state
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_notification_TMR = 240000 milliseconds
Switch# show redundancy

Purpose
Displays redundancy facility state information.
Displays the state of the during the ISSU process. At this
point in the ISSU process, use this command to check that
the standby supervisor engine is loaded with the new image.
Slot = 6
RP State = Active
Slot = 5
RP State = Standby
