Abstract

This document describes a protocol for carrying accounting information between a Network Access Server and a shared Accounting Server.

Implementation Note

This memo documents the RADIUS Accounting protocol. There has been some confusion in the assignment of port numbers for this protocol.

The officially assigned port number for RADIUS Accounting is 1813.

1. Introduction

Managing dispersed serial line and modem pools for large numbers of users can create the need for significant administrative support. Since modem pools are by definition a link to the outside world, they require careful attention to security, authorization and accounting.
