1.  Introduction

   The SNMP Management Framework at the time of this writing consists of
   five major components:

      -  An overall architecture, described in STD 62, RFC 3411
         [RFC3411].

      -  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
