Many changes you make could affect your remote connection to the switch so you should utilize a backup plan like the reload delay timer function on Cisco IOS devices.

So you’ve set the router to reload in 30 minutes while you complete your change.  You complete the change successfully.  How do you cancel the ticking time-bomb of the impending router reload?  Simply enter the “reload cancel” command:

Reload Cancel

r1#reload cancel
r1#

Being able to schedule a reload is a great feature and has saved my bacon more than once.  The biggest thing to remember is to disable the router reload once you have successfully completed your change.  To verify whether there are scheduled reloads, run the “show reload” command:

Show Reload

r1#show reload
Reload scheduled in 4 minutes and 55 seconds by console
Reload reason: Scheduled reload
