          RFC 1447             Party MIB 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.

          Management information is viewed as a collection of managed
          objects, residing in a virtual information store, termed the
          Management Information Base (MIB).  Collections of related
          objects are defined in MIB modules.  These modules are written
          using a subset of OSI's Abstract Syntax Notation One (ASN.1)
          [1], termed the Structure of Management Information (SMI) [2].

          The Administrative Model for SNMPv2 document [3] defines the
          properties associated with SNMPv2 parties, SNMPv2 contexts,
          and access control policies.  It is the purpose of this
          document, the Party MIB for SNMPv2, to define managed objects
          which correspond to these properties.


          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).

                      key which may be needed to support the
                      authentication protocol.  Although the value of
                      this variable may be altered by a management
                      operation (e.g., a SNMPv2 Set-Request), its value
                      can never be retrieved by a management operation:
                      when read, the value of this variable is the zero
                      length OCTET STRING.

                      The private authentication key is NOT directly
                      represented by the value of this variable, but
                      rather it is represented according to an encoding.
                      This encoding is the bitwise exclusive-OR of the
                      old key with the new key, i.e., of the old private
                      authentication key (prior to the alteration) with
                      the new private authentication key (after the
                      alteration).  Thus, when processing a received
                      protocol Set operation, the new private
                      authentication key is obtained from the value of
                      this variable as the result of a bitwise
                      exclusive-OR of the variable's value and the old
                      private authentication key.  In calculating the
                      exclusive-OR, if the old key is shorter than the
                      new key, zero-valued padding is appended to the
                      old key.  If no value for the old key exists, a
                      zero-length OCTET STRING is used in the
                      calculation."

              DESCRIPTION
                      "Locally held information about the MIB views
                      known to this SNMPv2 entity.

                      Each SNMPv2 context which is locally accessible
                      has a single MIB view which is defined by two
                      collections of view subtrees: the included view
                      subtrees, and the excluded view subtrees.  Every
                      such subtree, both included and excluded, is
                      defined in this table.

                      To determine if a particular object instance is in
                      a particular MIB view, compare the object
                      instance's OBJECT IDENTIFIER with each of the MIB
                      view's entries in this table.  If none match, then
                      the object instance is not in the MIB view.  If
                      one or more match, then the object instance is
                      included in, or excluded from, the MIB view
                      according to the value of viewType in the entry
                      whose value of viewSubtree has the most sub-
                      identifiers.  If multiple entries match and have
                      the same number of sub-identifiers, then the
                      lexicographically greatest instance of viewType
                      determines the inclusion or exclusion.

                      An object instance's OBJECT IDENTIFIER X matches
                      an entry in this table when the number of sub-
                      identifiers in X is at least as many as in the
                      value of viewSubtree for the entry, and each sub-
                      identifier in the value of viewSubtree matches its
                      corresponding sub-identifier in X.  Two sub-
                      identifiers match either if the corresponding bit
                      of viewMask is zero (the 'wild card' value), or if
                      they are equal.

                      Due to this 'wild card' capability, we introduce

                      Each bit of this bit mask corresponds to a sub-
                      identifier of viewSubtree, with the most

                      Thus, the OBJECT IDENTIFIER X of an object
                      instance is contained in a family of view subtrees
                      if the following criteria are met:

                           for each sub-identifier of the value of
                           viewSubtree, either:

                                the i-th sub-identifier of X is equal to
                                the i-th sub-identifier of the value of
                                viewSubtree.

                      If the value of this bit mask is M bits long and
                      there are more than M sub-identifiers in the
                      corresponding instance of viewSubtree, then the
                      bit mask is extended with 1's to be the required
                      length.

                      Note that when the value of this object is the
                      zero-length string, this extension rule results in
                      a mask of all-1's being used (i.e., no 'wild
                      card'), and the family of view subtrees is the one
                      view subtree uniquely identified by the
