                     Definitions of Managed Objects
                    for SMDS Interfaces using SMIv2

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.

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 objects for SMDS
   access interfaces. This includes the following access protocols:

             SIP [13]
             SIP/DXI [18] and [20]
             SIP/FR [19]
             SIP/ATM [24]

   This memo replaces RFC 1304 [12], and defines a MIB module which is
   both compliant to the SNMPv2 SMI and semantically-identical to the
   existing RFC 1304-based definitions.

   This memo also assumes application of the MIB II Interfaces group as
   defined in [9].

1.  The SNMPv2 Network Management Framework

   The SNMPv2 Network Management Framework consists of four major
   components.  They are:

      o RFC 1442 [1] which defines the SMI, the mechanisms used for
        describing and naming objects for the purpose of
        management.

      o STD 17, RFC 1213 [6] defines MIB-II, the core set of managed
        objects for the Internet suite of protocols.  Reference [12]
        defines the evolution of the Interfaces Group of MIB II in
        terms of extensions and precise applications of the objects.

      o RFC 1445 [4] which defines the administrative and other
        architectural aspects of the framework.

      o RFC 1448 [5] 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.

   This specification makes also use of:

      o RFC 1443 [2] which defines textual conventions for the
        specification of managed objects.

      o RFC 1444 [3] which defines conformance statements for the
        specification of managed objects.

2.  Objects

   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) [7]
   defined in the SMI.  In particular, each object has a name, a syntax,
   and an encoding.  The name is an object identifier, an
   administratively assigned name, which specifies an object type.  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 OBJECT
