7.9 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.
7.9.1 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.
7.9.1.1 Access-Challenge
Sent by a RADIUS server requesting more information in order to allow access. The access
point sends a proper response from the user and then sends another Access-Request message.
WPA Group Key
Update Timer
The
WPA Group Key Update Timer
is the rate at which the AP (if using
WPA-
PSK
key management) or
RADIUS
server (if using WPA key management)
sends a new group key out to all clients. The re-keying process is the WPA
equivalent of automatically changing the WEP key for an AP and all stations in a
WLAN on a periodic basis. Setting of the
WPA Group Key Update Timer
is also
supported in
WPA-PSK
mode. The ZyAIR default is
1800
seconds (30 minutes).
