8.4 Introduction to RADIUS

RADIUS is based on a client-sever model that supports authentication and accounting, where
the 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.
The ZyXEL Device is equipped with an internal RADIUS server. See
169 for more details.

8.5 Configuring RADIUS

server (see Section 14.1 on page
You can configure up to four RADIUS server profiles. Each profile also has one backup
authentication server and a backup accounting server. These profiles can be assigned to an
SSID profile in the SSID configuration screen
