Status of this Memo
This document is an Internet Draft. Internet Drafts are working
documents of the Internet Engineering Task Force (IETF), its Areas, and
its Working Groups. Note that other groups may also distribute working
documents as Internet Drafts.
Internet Drafts are 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 material or to cite
them other than as a "work in progress".

1. Introduction
This memo defines an experimental 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 dial-up modems and similar dial-up devices. This MIB module
provides a set of objects that are the minimum necessary to provide the
ability to monitor and control those devices, and is consistent with the
SNMP framework and existing SNMP standards.

2. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
o RFC 1442 which defines the SMI, the mechanisms used for describing
and naming objects for the purpose of management.
o RFC 1213 defines MIB-II, the core set of managed objects for the
Internet suite of protocols.
o RFC 1445 which defines the administrative and other architectural
aspects of the framework.
o RFC 1448 which defines the protocol used for network access to
managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2.1. 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.
