Configuring RADIUS

1-2

117385-B Rev 00

The RADIUS server is a computer equipped with server software (for example, a

UNIX workstation) that is located at a central office or campus. It has

authentication and access information in a form that is compatible with the client.

A network can have one server for both authentication and accounting, or one

server for each service.

The RADIUS client can be a router or a remote access server that is equipped with

client software and that typically resides on the same local area network (LAN)

segment as the server. The client is the network access point between the remote

users and the server.

RADIUS authentication lets you identify remote users before you give them

access to a central network site. RADIUS accounting enables the server to collect

data during a remote user’s dial-in session with the client. The server can then

determine billing charges.

Telephone Service) line and an ISDN (Integrated Services Digital Network).
