- 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.
