Authenticator

The Authenticator (the Switch) is an intermediary between the Authentication Server and the Client. The Authenticator

serves two purposes when utilizing 802.1x. The first purpose is to request certification information from the Client through

EAPOL packets, which is the only information allowed to pass through the Authenticator before access is granted to the

Client. The second purpose of the Authenticator is to verify the information gathered from the Client with the

Authentication Server, and to then relay that information back to the Client.
