            Management Information Base for Frame Relay DTEs
                              Using SMIv2

1.  Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

2.  Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in TCP/IP- based internets.
   In particular, it defines objects for managing Frame Relay interfaces
   on DTEs.

3.  The SNMPv2 Network Management Framework

   The major components of the SNMPv2 Network Management framework are
   described in the documents listed below.

   o    RFC 1902 [1] defines the Structure of Management
        Information (SMI), the mechanisms used for describing and
        naming objects for the purpose of management.

   o    STD 17, RFC 1213 [2] defines MIB-II, the core set of
        managed objects (MO) for the Internet suite of protocols.

   o    RFC 1905 [3] defines the protocol used for network access
        to managed objects.

   The framework is adaptable/extensible by defining new MIBs to suit
   the requirements of specific applications/protocols/situations.

   Managed objects are accessed via a virtual information store, the
   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 type is named by an OBJECT IDENTIFIER, which is 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, often a textual string, termed
   the descriptor, is used to refer to the object type.

4.  Overview

4.1.  Frame Relay Operational Model

   For the purposes of understanding this document, Frame Relay is
   viewed as a multi-access media, not as a group of point- to-point
   connections. This model proposes that Frame Relay is a single
   interface to the network (physical connection) with many destinations
   or neighbors (virtual connections). This view enables a network
   manager the ability to group all virtual connections with their
   corresponding physical connection thereby allowing simpler
   diagnostics and trouble shooting.

   With the extension of the interfaces MIB, it is possible to configure
   frame relay DLCs as individual interfaces and create ifTable entries
   for each. This is not recommended and is not directly supported by
   this MIB. Additionally, in the presence of demand circuits creation
   of individual ifEntries for each is not possible.

RFC 2115                  Frame Relay DTE MIB             September 1997

   Should the user wish to group DLCs together to associate them with a
   higher layer, or to associate a DLC with an unnumbered point-to-point
   service, the frame relay DTE MIB provides an entry in the
   frCircuitEntry record. For example, suppose one were to configure a
   company proprietary protocol to run above several of the frame relay
