RADIUS Overview

308640-15.1 Rev 00

1-13

This new behavior resembles the operation of a RAS (remote access server) in

local (non-DVS) mode and allows customers to perform usage-based billing of

multilink PPP sessions.

In addition, the new multilink PPP accounting feature:

• Does not report the Termination-Cause attribute in the accounting STOP

message.

• Ensures uniqueness by having the gateway locally generate the NAS-Port,

Session-Id, and Multi-Session-Id attributes.

Using RADIUS with a Dial Service

To use RADIUS accounting on the router, you must configure at least one of the

three Nortel Networks dial services: dial-on-demand, dial backup, or

bandwidth-on-demand. The dial service enables the router to activate a dial-up

connection when it receives an incoming call. For information about dial services,

see Configuring Dial Services.

Using RADIUS with Demand Circuit Groups (Site Manager only)

When configuring a RADIUS client using Site Manager, Site Manager

automatically configures a demand circuit group. However, you will need to

configure a protocol for the demand circuit group. See “

Select a Protocol for

RADIUS Authentication” on page 2-7.

To identify the remote user to the RADIUS server, the remote user uses the PPP

CHAP or PAP. The client includes the remote user’s CHAP name and secret or

PAP ID and password in the access challenge to the server. You cannot use VSAs

with demand circuit groups.

Using RADIUS-Compatible Servers with the RADIUS Client

The Nortel Networks RADIUS client can communicate with any

RADIUS-compatible server. You must configure the server’s IP address so that

the client can communicate with the server.
