Recently, during a very carefully planned, meticulously scripted change, I hit a bump in the road. It ended up not being a total show-stopper, but it did derail the change by about 30 minutes while we figured out a work-around. I think this kind of thing has probably happened to anyone who has been working on networks for a while. Invariably you get through (or abort!) whatever you’re working on and the following morning you start digging into what you hit. That’s when you discover that one command that would have saved your bacon last night. I call this the Morning-After command.
