7.15 Introduction to RADIUS

RADIUS is based on a client-sever model that supports authentication and accounting, where access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks among others:

•Authentication

Determines the identity of the users.

•Accounting

Keeps track of the client’s network activity.

RADIUS user is a simple package exchange in which your ZyAIR acts as a message relay between the wireless station and the network RADIUS server.

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.

•Access-Reject

Sent by a RADIUS server rejecting access.

•Access-Accept

Sent by a RADIUS server allowing access.
