Add NAS for Accounting Request Purpose

Accounting-Request packets are sent from a client (typically a Network Access Server or its proxy) to a RADIUS accounting server, and convey information used to provide accounting for a service
provided to a user. The client transmits a RADIUS packet with the Code field set to 4 (Accounting-Request).

When you want to add NAS to your Radius Accounting Server, you have to know your network topology, because your configuration depent on your network topology.

For example, if your network topology like this

NAS Client – Radius Accounting Server

You may just add

– NAS Client IP address OR NAS Client identifier

– NAS Client port OR NAS Client port type

– NAS Client Shared Key

if your topology like this

NAS Client – NAS Proxy – Radius Accounting Server

You have to add

– NAS Client IP address OR NAS Client identifier

– NAS Client port OR NAS Client port type

– NAS Client Shared Key

– NAS Proxy IP address OR NAS Proxy identifier

– NAS Proxy port OR NAS Proxy port type

– NAS Proxy Shared Key

That parameter has to be same with the parameter configured on NAS Client & NAS Proxy.

In the practical environment, you may think that NAS Client is your GGSN and NAS Proxy is your Radius Server.

You may read the RFC2866 ( http://www.ietf.org/rfc/rfc2866.txt )to get detail explanation for Accounting Request. My writen above is just for practical use
