Thanks to Anisha with Cisco Systems for this idea. We were in Brian McGahan's CCIE Security 5 Day Bootcamp, and she realized it would be nice to have a Quick Ref of his troubleshooting/verification commands. There is a bazillion shows and debugs it seems, but you only need a subset to be successful in the lab. Here is the first part of the "cheat sheet". The rest will follow in the respective categories in the blog. Please let me know via comment if you see errors or have additions. I added to Brian's classroom commands with some of my own. I also took a few from the Cisco Press ASA All-In-One Guide. It is an excellent text for your Kindle!
