Cisco MAB = MAC Authentication Bypass

Interesting new project for an engineer that has spent his career in everything from small LAN, large WAN, and data center support.

While reading up on the protocol, I have found it to be most suited for a campus style network.

Cisco MAB seems well suited for this scenario.

The network has approximately 500 nodes in a large single building spread about several floors. This campus consists of a pair of Cisco Catalyst 6509 switches for the Layer3 core. Approximately 30 campus Layer2 switches, which are mostly Cisco Catalyst 4006.

Why MAB, and whats it for? I will explain this in an upcoming projects implementation post. Read more…
