Welcome! With this UA-cam channel I plan on making some networking related videos just to help myself and others better understand how some of these technologies work. Sometimes I like to get past all the marketing lingo and get to the nuts and bolt of HOW something works! Some videos may be basic while I may get into the weeds with others. I have a few upcoming ideas in mind but I may not be opposed to exploring something if it has a popular demand. Will probably stay within the Cisco networking/security fields (Cisco Routing/Switching, ISE, Firepower, DNA, etc...)
