I'm trying to get a handle on the maximum number of ports that can be utilized on the ASA 5550. I looked at this video on youtube http://youtube.com/results?search_query=asa+5550&search_type= and it is clear there are 8(gig ethernet)+4(SFP)+1 (10/100 ethernet) for a total of 13. My question is whether you can use all these ports. I know on some models or under certain licenses you must selct which ports you want to use, e.g. coppr v fiber, but you can't use them all.
