DXS-3400 Series Lite Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide Figure 9-6The Authentication Server Authenticator The Authenticator (the Switch) is an intermediary between the Authentication Server and the Client. The Authenticator serves two purposes when utilizing the 802.1X function. 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. Figure 9-7The Authenticator Three steps must be implemented on the Switch to properly configure the Authenticator. • The 802.1X State must be Enabled. (Security > 802.1X > 802.1X Global Settings) • The 802.1X settings must be implemented by port (Security > 802.1X > 802.1X Port Settings) • A RADIUS server must be configured on the Switch. (Security > RADIUS > RADIUS Server Settings) Client The Client is simply the end station that wishes to gain access to the LAN or Switch services. All end stations must be running software that is compliant with the 802.1X protocol. For users running windows XP and windows Vista, that software is included within the operating system. All other users are required to attain 802.1X client software from an outside source. The Client will request access to the LAN and or Switch through EAPOL packets and, in turn will respond to requests from the Switch. 305
