Radius Settings
Radius servers provide centralized authentication services to wireless clients. Two Radius serv-
ers can be defined: one acts as a primary, and the other acts as a backup.
Two user authentication methods can be enabled: one based on MAC address filter, the other
based on 802.1x EAP authentication.
MAC address filtering based authentication requires a MAC address filter table to be created in
either the GW-AP54SAG (as described in the section
MAC Filtering Settings
) and/or the Radius
server. During the authentication phase of a wireless station, the MAC address filter table is
searched for a match against the wireless client’s MAC address to determine whether the sta-
tion is to be allowed or denied to access the network.
The Radius server can also be used for 802.1x EAP authentication. IEEE 802.1x is an IEEE
standard that is based on a framework that involves stations to be authenticated (called Suppli-
cant), an authentication server (a Radius Server) that provides authentication services, and an
authenticator that provides necessary translation and mediating functions between the authen-
tication server and the stations to be authenticated. The GW-AP54SAG acts as an authentica-
