RADIUS Accounting
Status of this Memo
This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
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 early deployment of RADIUS Accounting was done using the
erroneously chosen port number 1646, which conflicts with the "sa-
msg-port" service. The officially assigned port number for RADIUS
Accounting is 1813.
