Config snippets : Cisco: Reload command might be handy

-

Few times in the past when I was doing some changes on Cisco devices remotely I was a victim of myself, when wrong order of commands just disconnected me from device without ability to connect back. After few experiences of this kind I discovered magic command “reload” which can help and save the day.

So, when doing changes which can impact remote terminal connection to device it’s a good idea to initiate reload before making changes. In case something goes wrong device will reboot itself and will come back with previous configuration.

lab-r01#
lab-r01#reload in 15
Reload scheduled in 15 minutes by admin on console
Reload reason: Reload Command
Proceed with reload? [confirm]
lab-r01#
*Mar  1 03:11:11.659: %SYS-5-SCHEDULED_RELOAD: Reload requested for 03:26:09 UTC Fri Mar 1 2002 at 03:11:09 UTC Fri Mar 1 2002 by admin on console. Reload Reason: Reload Command.
lab-r01#

Once everything is configured and connectivity to device was not lost we can cancel reload process.

lab-r01#
lab-r01#reload cancel
lab-r01#

***
*** --- SHUTDOWN ABORTED ---
***

*Mar  1 03:11:19.415: %SYS-5-SCHEDULED_RELOAD_CANCELLED: Scheduled reload cancelled at 03:11:19 UTC Fri Mar 1 2002
lab-r01#

It is very helpful and can save time and rescue from trouble.
