He discusses the different ways to implement MAC address filtering as well as the benefits and draw backs. He compares port security to authenticating users on a port by port basis. The most common way to filter and authenticate users in this way is 802.1x. He finishes by discussing the technologies that allow 802.1x: PAP, CHAP, EAP and RADIUS.
