- I logged in
- I started updating the ACL
- I hit a blackspot in my 3g coverage
- My command stops at "router(config)#access-"
- I get a call from my partner saying "what did you do to our internet!"
In the case of updating a device remotely, it is as easy as:
router# reload in 2 router# conf t router(config)# [type in desired commands] router(config)# exit router# reload cancel
If the commands are entered in fine, then cancel the reload. If there is a problem, then the router will reboot and resort to the startup config.
