More often than not we find ourselves doing this in 2019 to Cisco switches that are now used for labbing or even on Cisco switches that are still used in a production environment. The problem I’ve seen is that, we (as engineers) have some much to remember, we often forget the little things or better yet, we lose the skills we don’t use but fear not, this article hopes to bring back at least one of those skills!
