RADIUS Server MIB
1. Status of this Memo
This document is an Internet-Draft. Internet-Drafts are working docu-
ments of the Internet Engineering Task Force (IETF), its areas, and
its working groups. Note that other groups may also distribute work-
ing documents as Internet-Drafts.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference mate-
rial or to cite them other than as ``work in progress.''
To learn the current status of any Internet-Draft, please check the
``1id-abstracts.txt'' listing contained in the Internet-Drafts Shadow
Directories on ds.internic.net (US East Coast), nic.nordu.net
(Europe), ftp.isi.edu (US West Coast), or munnari.oz.au (Pacific Rim).
The distribution of this memo is unlimited. It is filed as <draft-
ietf-radius-servmib-02.txt>, and expires October 1, 1997. Please send
comments to the authors.
2. Abstract
This memo defines a set of extensions which instrument RADIUS server
functions. These extensions represent a portion of the Management
Information Base (MIB) for use with network management protocols in
the Internet community. Using these extensions IP-based management
stations can manage RADIUS 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
servers.
RADIUS servers are today widely deployed by dialup Internet Service
Providers, in order to provide for authentication, authorization, and
accounting. As a result, the effective management of RADIUS 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
specific instantiation of the object. For human convenience, we often
use a textual string, termed the descriptor, to refer to the object
type.
5. Overview
This MIB module contains a scalar as well as a single table:
(1) the RADIUS Client Table contains one row for each
RADIUS client that the server shares a secret with.
Each entry in the RADIUS Client Table includes twelve counts present-
ing a view of the activity of the RADIUS server.
