6.7.2 Authentication Process according to
IEEE 802.1X
A supplicant attempts to communicate via a device port.
The device requests authentication from the supplicant. At this time, only
EAPOL traffic is allowed between the supplicant and the device.
The supplicant replies with its identification data.
The device forwards the identification data to the authentication server.
The authentication server responds to the request in accordance with the
access rights.
The device evaluates this response and provides the supplicant with
access to this port (or leaves the port in the blocked state).
6.7.3 Preparing the Device for the
IEEE 802.1X Port Authentication
Configure your own IP parameters (for the device).
Globally enable the 802.1X port authentication function.
Set the 802.1X port control to "auto". The default setting is "force-
authorized".
Enter the "shared secret" between the authenticator and the Radius
server. The shared secret is a text string specified by the RADIUS server
administrator.
Enter the IP address and the port of the RADIUS server. The default UDP
port of the RADIUS server is port 1812.
