1.  Introduction

   A management system contains:  several (potentially many) nodes, each
   with a processing entity, termed an agent, which has access to
   management instrumentation; at least one management station; and, a
   management protocol, used to convey management information between
   the agents and management stations.  Operations of the protocol are
   carried out under an administrative framework which defines
   authentication, authorization, access control, and privacy policies.

   Management stations execute management applications which monitor and
   control managed elements.  Managed elements are devices such as
   hosts, routers, terminal servers, etc., which are monitored and
   controlled via access to their management information.

   The management protocol, version 2 of the Simple Network Management
   Protocol [1], may be used over a variety of protocol suites.  It is
   the purpose of this document to define how the SNMPv2 maps onto an
   initial set of transport domains.  Other mappings may be defined in
   the future.

   Although several mappings are defined, the mapping onto UDP is the
   preferred mapping.  As such, to provide for the greatest level of
   interoperability, systems which choose to deploy other mappings
   should also provide for proxy service to the UDP mapping.

1.1.  A Note on Terminology

   For the purpose of exposition, the original Internet-standard Network
   Management Framework, as described in RFCs 1155 (STD 16), 1157 (STD
