Hi Samuel I think it is a really informative session you provided & so thank you really for all the efforts put into to creating it. Just wondering though as would you mind elaborate more on how does wireless lan controllers can communicate with the various access points which protocols used & is there TCP / UDP types of controllers or they are only one types. Also would you consider NMS (Network Management System) or ACS (Automatic Configuration Server) as wireless lan Controllers ?

[@SamuelBarlass]

Hey! The most common protocol used for Wireless LAN Controllers is CAPWAP. Generally I would not, but keep in mind that a WLC can be built in to other systems. NMS and ACS solutions are primarily automation/orchestration platforms.

Why you post once in two weeks ? 😅

[@SamuelBarlass]

Hey - I'm trying to start consistently posting once a week. So far I've been posting on Tuesday mornings. My time is split between my day job, teaching part time, my family, and these videos you see are in addition to all that!
