Hi Carl,

802.1X is a client-server-based access control and authentication protocol that prevents clients from connecting to a LAN through publicly accessible ports unless they are authenticated. The authentication server authenticates each client connected to a switch port before making available any services offered by the switch or the LAN.

You need a Switch which supports 802.1x (All Cisco switches support that ), Cisco ACS AAA Server, 802.1X client supplicant on the host PC.

what kind of client supplicant do you mean here? and do they generally use certificates ?

Suplicant in raw terms is your windows network card. That should have dot1x feature. Yes you would need a server certificate on Radius server.
