This chapter shows you how to configure the ZyXEL Device to use an external RADIUS
server.

6.1 About RADIUS

You can use an external RADIUS (Remote Authentication Dial-In User Service) server to
authenticate the subscriber connections and keep track of accounting information.
RADIUS is based on a client-sever model that supports authentication, authorization and
accounting. This system is the client and the server is the external RADIUS server.
RADIUS is a simple package exchange in which the ZyXEL Device acts as a message relay
between the subscribers and the RADIUS server to establish a connection. When you enable
RADIUS authentication, the ZyXEL Device uses RADIUS protocol (RFC 2865, 2866) to send
subscriber authentication information to the external RADIUS server.
When you use an external RADIUS server for accounting, you can use either accumulation or
time to finish accounting. See
to finish accounting.
