Step 3
Switch# show issu state [detail]
Step 4
Switch# show redundancy [states]
This example shows how to start the ISSU process, boot the standby supervisor engine in the Standby
Hot state, and load the standby supervisor engine slot (6) with the new IOS XE software image:
Switch> enable
Switch# issu loadversion 5 bootflash:new_image 6 slavebootflash:new_image
%issu loadversion executed successfully, Standby is being reloaded
Switch# show issu state detail
Switch# show redundancy states

Purpose
Displays the state of ISSU during the ISSU process. At this
point in the ISSU process, use this command to check that
the standby supervisor engine is loaded and is in SSO mode.
It may take several minutes after entering the
issu loadversion command for Cisco IOS XE software to
load onto the standby supervisor engine and the standby
supervisor engine to transition to SSO mode. If you enter
the show issu state command too quickly, you may not see
the information you need.
Displays redundancy facility state information.
