2. Abstract
This memo defines a set of extensions which instrument RADIUS account-
ing server functions. These extensions represent a portion of the Man-
agement Information Base (MIB) for use with network management proto-
cols in the Internet community. Using these extensions IP-based man-
agement stations can manage RADIUS accounting servers.
3. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects used for managing RADIUS
accounting servers.
RADIUS accounting servers are today widely deployed by dialup Internet
Service Providers, in order to provide accounting services. As a
result, the effective management of RADIUS accounting servers is of
considerable importance.

4. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major compo-
nents. They are:
o RFC 1902 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of management.
o RFC 1905 which defines the protocol used for network access to
managed objects.
o RFC 1907 defines the core set of managed objects for the
Internet suite of protocols.
o RFC 1909 which defines the administrative aspects of the
framework.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
4.1. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are defined
using the subset of Abstract Syntax Notation One (ASN.1) defined in
the SMI. In particular, each object object type is named by an OBJECT
IDENTIFIER, an administratively assigned name. The object type
together with an object instance serves to uniquely identify a spe-
cific instantiation of the object. For human convenience, we often use
a textual string, termed the descriptor, to refer to the object type.
5. Overview
The RADIUS accounting protocol, described in [2], distinguishes
between the client function and the server function. In RADIUS
accounting, clients send Accounting-Requests, and servers reply with
Accounting-Responses. Typically NAS devices implement the client func-
tion, and thus would be expected to implement the RADIUS accounting
client MIB, while RADIUS accounting servers implement the server func-
tion, and thus would be expected to implement the RADIUS accounting
server MIB.
However, it is possible for a RADIUS accounting entity to perform both
client and server functions. For example, a RADIUS proxy may act as a
server to one or more RADIUS accounting clients, while simultaneously
acting as an accounting client to one or more accounting servers. In
such situations, it is expected that RADIUS entities combining client
and server functionality will support both the client and server MIBs.

5.1. Selected objects
This MIB module contains five scalars as well as a single table:
(1) the RADIUS Accounting Client Table contains one row for each
RADIUS accounting client that the server shares a secret with.
Each entry in the RADIUS Accounting Client Table includes eleven
entries presenting a view of the activity of the RADIUS accounting
server.
