I love this command. I used to love it more when I was supporting a lot of remote CPE remotely some years ago now but I still love it now nonetheless!
Anyone who performs that sort of role, supporting LAN, WAN devices or remote CPE like me will have at some point made a change and then…………noooooooooo!!!!!!!!!! You have just locked yourself out or worse broke it Now this is not to say you are a bad engineer or a cowboy but for that one moment……..ow……..then you start to feel all hot :S
So what are the consequences? It could just be plain annoying and you might have to get someone on site to undo your mistake but in more extreme situations you could have just caused an outage and for users passing through an unmanned site. Lets face it these types of cock ups can range from the providing your colleagues with amusement to career limiting mistakes.
Now if its appropriate and lets say you are making changes to access-lists, crypto configuration or something that could lock you out or stop the router performing its primary function then use the “reload” command to protect yourself.
Before you commence that dangerous step simply type:
“reload in X” (where X is in minutes)
….then do what you need to……in less than however minutes you specified…..phew…..type:
That’s it, it’s done! And if the worst happens you know you will be able to get back on to it in a few minutes following a reload.
