       DESCRIPTION
              "IP version neutral revision, incorporating the
               following revisions:

               - Added udpHCInDatagrams and udpHCOutDatagrams in order
                 to provide high-capacity counters for fast networks.
               - Added text to the descriptions of all counter objects
                 to indicate how discontinuities are detected.
               - Deprecated the IPv4-specific udpTable and replaced it
                 with the version neutral udpEndpointTable.  This
                 table includes support for connected UDP endpoints
                 and support for identification of the operating
                 system process associated with a UDP endpoint.
               - Deprecated the udpGroup and replaced it with object
                 groups representing the current set of objects.
               - Deprecated udpMIBCompliance and replaced it with
                 udpMIBCompliance2, which includes the compliance
                 information for the new object groups.

               This version published as RFC 4113."

   udpEndpointTable OBJECT-TYPE
       SYNTAX     SEQUENCE OF UdpEndpointEntry
       MAX-ACCESS not-accessible
       STATUS     current
       DESCRIPTION
              "A table containing information about this entity's UDP
               endpoints on which a local application is currently
               accepting or sending datagrams.
               The address type in this table represents the address
               type used for the communication, irrespective of the
               higher-layer abstraction.  For example, an application
               using IPv6 'sockets' to communicate via IPv4 between
               ::ffff:10.0.0.1 and ::ffff:10.0.0.2 would use
               InetAddressType ipv4(1).

               Unlike the udpTable in RFC 2013, this table also allows
               the representation of an application that completely
               specifies both local and remote addresses and ports.  A
               listening application is represented in three possible
               ways:

               1) An application that is willing to accept both IPv4
                  and IPv6 datagrams is represented by a
                  udpEndpointLocalAddressType of unknown(0) and a
                  udpEndpointLocalAddress of ''h (a zero-length
                  octet-string).

               2) An application that is willing to accept only IPv4
                  or only IPv6 datagrams is represented by a
                  udpEndpointLocalAddressType of the appropriate
                  address type and a udpEndpointLocalAddress of
                  '0.0.0.0' or '::' respectively.

               3) An application that is listening for datagrams only
                  for a specific IP address but from any remote
                  system is represented by a
                  udpEndpointLocalAddressType of the appropriate
                  address type, with udpEndpointLocalAddress
                  specifying the local address.

               In all cases where the remote is a wildcard, the
               udpEndpointRemoteAddressType is unknown(0), the
               udpEndpointRemoteAddress is ''h (a zero-length
               octet-string), and the udpEndpointRemotePort is 0.

               If the operating system is demultiplexing UDP packets
               by remote address and port, or if the application has
               'connected' the socket specifying a default remote
               address and port, the udpEndpointRemote* values should
               be used to reflect this."

                  IPv4 and IPv6 datagrams, the value of this object

       STATUS     current
       DESCRIPTION
              "The compliance statement for systems that implement
               UDP.

               There are a number of INDEX objects that cannot be
               represented in the form of OBJECT clauses in SMIv2, but
               for which we have the following compliance
               requirements, expressed in OBJECT clause form in this
               description clause:

               -- DESCRIPTION
