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.
Three steps must be implemented on the Switch to properly configure the Authenticator.
1.The 802.1x State must be enabled to Port Base on the Switch Information (Advanced Settings) window under Switch 802.1x (Configuration > Advanced Settings).
2.The 802.1x settings must be implemented by port. (Configuration > Port Access Entity > 802.1x Capability Settings).
3.A RADIUS server must be configured on the Switch on the Authentic RADIUS Server Setting window (Configuration > Port Access Entity > RADIUS Server).
