Transport Mappings for version 2 of the Simple Network Management Protocol (SNMPv2)

          RFC 1449        Transport Mappings for SNMPv2       April 1993


          1.  Introduction

          A network 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 both authentication and
          authorization policies.

          Network management stations execute management applications
          which monitor and control network elements.  Network elements
          are devices such as hosts, routers, terminal servers, etc.,
          which are monitored and controlled through 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, 1157,
          and 1212, is termed the SNMP version 1 framework (SNMPv1).
          The current framework is termed the SNMP version 2 framework
          (SNMPv2).
