Figure 11- 6. Authentication Server
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. (DES-3828P Web Management Tool).
2. The 802.1x settings must be implemented by port. (Security > 802.1x > Configure 802.1x
Authenticator Parameter).
3. A RADIUS server must be configured on the Switch. (Security > 802.1x >Authentic Radius
Server).
