Understanding Switching

This lession covers an introduction to switching technology.

We’ll begin by looking at traditional shared LAN technologies. We’ll then look at LAN switching basics, and then some key switching technologies, such as spanning tree and multicast controls.

Let’s begin our discussion by reviewing shared LAN technologies.
