Command History
Usage Guidelines It might take several seconds after the issu loadversion command is entered for Cisco IOS 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 soon, you might not see the information you need.
