1.  Abstract

   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 objects used for managing ATM-based
   interfaces, devices, networks and services.

   This memo replaces RFC 1695 [24].  Changes relative to RFC 1695 are
   summarized in the MIB module's REVISION clause.

   Textual Conventions used in this MIB are defined in [6] and [19].

2.  The SNMP Network Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   0    An overall architecture, described in RFC 2271 [1].

   0    Mechanisms for describing and naming objects and events
        for the purpose of management.  The first version of this
        Structure of Management Information (SMI) is called SMIv1 and
        described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC
        1215 [4].  The second version, called SMIv2, is described in RFC
        1902 [5], RFC 1903 [6] and RFC 1904 [7].

   0    Message protocols for transferring management information.  The
        first version of the SNMP message protocol is called SNMPv1 and
        described in STD 15, RFC 1157 [8].  A second version of the SNMP
        message protocol, which is not an Internet standards track
        protocol, is called SNMPv2c and described in RFC 1901 [9] and
        RFC 1906 [10].
