     Internet-Draft             IPv6 MIB               October 1996
     
     
     1.  The SNMPv2 Network Management Framework
     
     The SNMPv2 Network Management Framework presently consists  of
     three major components.  They are:
     
     o    the SMI, described in RFC 1902 [1] - the mechanisms  used
          for  describing  and  naming  objects  for the purpose of
          management.
     
     o    the MIB-II, described in  RFC 1213/STD 17 [3] - the  core
          set   of  managed  objects  for  the  Internet  suite  of
          protocols.
     
     o    RFC 1157 [4] and RFC 1905 [5] which define  two  versions
          of  the  protocol  used  for  network  access  to managed
          objects.
     
     The Framework permits  new  objects  to  be  defined  for  the
     purpose of experimentation and evaluation.
     
     
     
     1.1.  Object Definitions
     
     Managed objects are accessed via a virtual information  store,
     termed the Management Information Base or MIB.  Objects in the
     MIB are defined using the subset of Abstract  Syntax  Notation
     One  (ASN.1)  defined  in the SMI.  In particular, each object
     object  type  is   named   by   an   OBJECT   IDENTIFIER,   an
     administratively assigned name.  The object type together with
     an object instance serves  to  uniquely  identify  a  specific
     instantiation  of the object.  For human convenience, we often
     use a textual string, termed the descriptor, to refer  to  the
     object type.

     Internet-Draft             IPv6 MIB               October 1996
     
     
     2.  Overview
     
     The objects in  this  MIB  are  arranged  into  the  following
     groups:
     
                         - IPv6 General
                         - ICMPv6
                         - UDP
                         - TCP
     
     These groups  are  the  basic  unit  of  conformance:  if  the
     semantics  of a group is applicable to an implementation, then
     it must implement all objects in that group.  For example,  an
     implementation  must implement the TCP group if and only if it
     implements  the  TCP  over   IPv6   protocol.    At   minimum,
     implementations must implement IPv6 General and ICMPv6 groups.
     
     The IPv6 General group consists of 6 tables:
     
       - ipv6IfTable
     
            The IPv6 Interfaces table contains information  on  the
            entity's IPv6 interfaces.
     
       - ipv6IfStatsTable
     
            This  table  contains  information   on   the   traffic
            statistics of the entity's IPv6 interfaces.
     
       - ipv6AddrPrefixTable
     
            The IPv6 Address Prefix table contains  information  on
            Address  Prefixes that are associated with the entity's
            IPv6 interfaces.
     
       - ipv6AddrTable
     
            This table contains the addressing information relevant
            to the entity's IPv6 interfaces.
     
       - ipv6RouteTable
     
            The IPv6 routing table contains an entry for each valid
            IPv6   unicast  route  that  can  be  used  for  packet
            forwarding determination.

     Internet-Draft             IPv6 MIB               October 1996
     
     
       - ipv6NetToMediaEntryTable
     
            The IPv6 address translation  table  contain  the  IPv6
            Address to `physical' address equivalences.
     
     The ICMPv6 group consists of 1 table:
     
       - ipv6IfIcmpTable
     
            This  table  contains   information   on   the   ICMPv6
            statistics of the entity's IPv6 interfaces.
     
     The UDP group consists of 1 table:
     
       - ipv6UdpTable
     
            This table contains information  on  the  entity's  UDP
            end-points  on  which  a local application is currently
            accepting datagrams.
     
     The TCP group consists of 1 table:
     
       - ipv6TcpConnTable
     
            This table  contains  information  about  the  entity's
            existing TCP connections.
     
     In addition to the object definitions, this document defines a
     number  of  textual  convention to represent object types that
     are specific to IPv6.
     
     
     
     3.  IPv6 Address Representation
     
     
     The IPv6 MIB defined in this memo  uses  an  OCTET  STRING  of
     length  16  to represent 128-bit IPv6 address in network byte-
     order.  This approach allows to  implement  IPv6  MIB  without
     requiring  any  changes  to  the SNMPv2 SMI and compliant SNMP
     implementations.  A drawback of this approach is that,  if  an
     IPv6  address  is used for the object instance identification,
     16 sub-identifiers are used to form the instance-identifier.
     
     An alternative approach would be to  introduce  a  new  object

     type  that  represents an IPv6 address as a string of four 32-
     bit unsigned integers.  Only 4 sub-identifiers would  be  used
     to  form  the  instance-identifier  from an IPv6 address.  The
     disadvantage of this solution is that it would require changes
     to the SMI and SNMPv2 implementations to support IPv6 MIB.

              "Setting this object to the value 'false(2)' has
              the effect of invalidating the corresponding entry
              in the ipv6NetToMediaTable.  That is, it effectively
              disassociates the interface identified with said
              entry from the mapping identified with said entry.
              It is an implementation-specific matter as to
              whether the agent removes an invalidated entry
              from the table.  Accordingly, management stations
              must be prepared to receive tabular information
              from agents that corresponds to entries not
              currently in use.  Proper interpretation of such
              entries requires examination of the relevant
              ipv6NetToMediaInvalid object."
