1.  The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

      o  An overall architecture, described in an Architecture for
         Describing SNMP Management Frameworks [ARCH].

      o  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 [V1SMI], STD 16, RFC 1212 [V1CONCISE] and RFC
         1215 [V1TRAPS].  The second version, called SMIv2, is described
         in STD 58, RFC 2578 [V2SMI], STD 58, RFC 2579 [V2TC] and STD
         58, RFC 2580 [V2CONFORM].

      o  Message protocols for transferring management information.  The
         first version of the SNMP message protocol is called SNMPv1 and
         described in STD 15, RFC 1157 [V1PROTO].  A second version of
         the SNMP message protocol, which is not an Internet standards
         track protocol, is called SNMPv2c and described in RFC 1901
         [V2COMMUNITY] and RFC 1906 [V2TRANS].  The third version of the
         message protocol is called SNMPv3 and described in RFC 1906
         [V2TRANS], Message Processing and Dispatching [V3MPC] and
         User-based Security Model [V3USM].

      o  Protocol operations for accessing management information.  The
         first set of protocol operations and associated PDU formats is
         described in STD 15, RFC 1157 [V1PROTO].  A second set of
         protocol operations and associated PDU formats is described in
         RFC 1905 [V2PROTO].

      o  A set of fundamental applications described in SNMPv3
         Applications [V3APPS] and the view-based access control
         mechanism described in View-based Access Control Model
         [V3VACM].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [V3INTRO].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
