Hi All,
With reference to the following bug ID:-
CSCwd20481 - Command "reload cancel" fails when the system clock changes to a later time in between "reload in x"
We ran into this bug today on a Cisco 9300 series Switch running IOS version 17.3.4. Workaround that seemed to work, was to just re-issue the "reload in x" command again, following getting the error message. This then allowed us to cancel the reload.
Hope this helps.
