The only real way to do this at the network level is by using NAC (Network Access Control). This can stop the client getting on the network unless the client is authorised (at the network layer).

What about a Cisco switch with port security?

Fair point, would depend on the size of the network as the administrative overhead would be a nightmare

True... depending on how often people plug into the network. There a a great deal of unknown variables.

Check out PacketFence . Fully featured NAC for free (also available as a virtual appliance). Just plug into your switch and you're in business.
