1.  The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o  An overall architecture, described in RFC 2571 [RFC2571].

   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 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215
      [RFC1215].  The second version, called SMIv2, is described in STD
      58: RFC 2578 [RFC2578], RFC 2579 [RFC2579] and RFC 2580 [RFC2580].

   o  Message protocols for transferring management information.  The
      first version of the SNMP message protocol is called SNMPv1 and
