6.6 Network Authentication

You can set the Prestige and your network to authenticate a wireless station before the wireless

station can communicate with the Prestige and the wired network to which the Prestige is

connected.

6.6.1 EAP

EAP (Extensible Authentication Protocol) is an authentication protocol designed originally to

run over PPP (Point-to-Point Protocol) frame in order to support multiple types of user

authentication. By using EAP to interact with an EAP-compatible RADIUS server, the access

point helps a wireless station and a RADIUS server to perform mutual authentication.

6.6.1.1 RADIUS

RADIUS is based on a client-sever model that supports authentication, authorization and

accounting. The access point is the client and the server is the RADIUS server. The RADIUS

server handles the following tasks:

• Authentication

Determines the identity of the users.

• Authorization

Determines the network services available to authenticated users once they are connected

to the network.

• Accounting

Keeps track of the client’s network activity.

RADIUS is a simple package exchange in which your Prestige acts as a message relay

between the wireless station and the network RADIUS server.

6.6.1.2 Types of RADIUS Messages

The following types of RADIUS messages are exchanged between the access point and the

RADIUS server for user authentication:

• Access-Request

Sent by an access point requesting authentication.
