6.5.2 Authentication process
A supplicant attempts to communicate via a Switch port.
X The Switch requests authentication from the supplicant. At this time, only
EAPOL traffic is allowed between the supplicant and the Switch.
X The supplicant replies with its identification data.
X The Switch forwards the identification data to the authentication server.
X The authentication server responds to the request in accordance with the
access rights.
X The Switch evaluates this response and provides the supplicant with ac-
cess to this port (or leaves the port in the blocked state).
6.5.3 Preparing the Switch for the
802.1X port authentication
Configure your own IP parameters (for the switch).
Globally enable the 802.1X port authentication function.
Set the 802.1X port control to "auto". The default setting is "force-autho-
rized".
Enter the "shared secret" between the authenticator and the Radius serv-
er. The shared secret is a text string specified by the RADIUS server ad-
ministrator.
Enter the IP address and the port of the RADIUS server. The default UDP
port of the RADIUS server is port 1812.
