We’ve all had those oh-shit moments when changing an ip, duplex or making other changes and losing connection with a device that will end up costing someone a trip on site and possible downtime.

The best way I’ve found is to cover yourself with this command:


If everything goes according to plan, cancel the reload and write mem, but if not, you’ve minimized downtime.

Kitty has an option to send a script file, which issues commands all at once. This is helpful when changing internet connections remotely. If  you were to copy and pasted the configuration, it would stop where the ip changed but before the correct default route was put in for instance.
