1.  Status of this Memo

  This memo defines an experimental portion of the Management
  Information Base (MIB) for use with network management protocols in
  TCP/IP-based internets.

  This memo does not specify a standard for the Internet community.
  However, after experimentation, if sufficient consensus is reached in
  the Internet community, then a subsequent revision of this document
  may be placed in the Internet-standard MIB.

  Distribution of this memo is unlimited.

2.  Historical Perspective

  As reported in RFC 1052, IAB Recommendations for the Development of
  Internet Network Management Standards [1], a two-prong strategy for
  network management of TCP/IP-based internets was undertaken.  In the
  short-term, the Simple Network Management Protocol (SNMP), defined in
  RFC 1067, was to be used to manage nodes in the Internet community.
  In the long-term, the use of the OSI network management framework was
  to be examined.  Two documents were produced to define the management
  information: RFC 1065, which defined the Structure of Management
  Information (SMI), and RFC 1066, which defined the Management
  Information Base (MIB).  Both of these documents were designed so as
  to be compatible with both the SNMP and the OSI network management
  framework.

  This strategy was quite successful in the short-term: Internet-based
  network management technology was fielded, by both the research and
  commercial communities, within a few months.  As a result of this,
  portions of the Internet community became network manageable in a
  timely fashion.

  As reported in RFC 1109, Report of the Second Ad Hoc Network
  Management Review Group [2], the requirements of the SNMP and the OSI
  network management frameworks were more different than anticipated.
  As such, the requirement for compatibility between the SMI/MIB and
  both frameworks was suspended.  This action permitted the operational
  network management framework, based on the SNMP, to respond to new
  operational needs in the Internet community by producing MIB-II.

  In May of 1990, the core documents were elevated to "Standard
  Protocols" with "Recommended" status.  As such, the Internet-
  standard network management framework consists of: Structure and
  Identification of Management Information for TCP/IP-based internets,
  RFC 1155 [3], which describes how managed objects contained in the
  MIB are defined; Management Information Base for Network Management
  of TCP/IP-based internets, which describes the managed objects
  contained in the MIB, RFC 1156 [4]; and, the Simple Network
  Management Protocol, RFC 1157 [5], which defines the protocol used to
  manage these objects.

  Consistent with the IAB directive to produce simple, workable systems
  in the short-term, the list of managed objects defined in the
  Internet-standard MIB was derived by taking only those elements which
  are considered essential.  However, the SMI defined three
  extensibility mechanisms: one, the addition of new standard objects
  through the definitions of new versions of the MIB; two, the addition
  of widely-available but non-standard objects through the experimental
  subtree; and three, the addition of private objects through the

RFC 1162                        CLNS MIB                       June 1990


  enterprises subtree.  Such additional objects can not only be used
  for vendor-specific elements, but also for experimentation as
  required to further the knowledge of which other objects are
  essential.

  Since the publication of the Internet-standard MIB, experience has
  lead to a new document, termed MIB-II [6], being defined.

  This memo defines extensions to the MIB using the second method.  It
  contains definitions of managed objects used for experimentation.
  After experimentation, if sufficient consensus is reached in the
  Internet community, then a subsequent revision of this memo may be
  placed in the Internet-standard MIB.

3.  Objects

  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) [7]
  defined in the SMI.  In particular, each object has a name, a syntax,
  and an encoding.  The name is an object identifier, an
  administratively assigned name, which specifies an object type.  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 OBJECT
  DESCRIPTOR, to also refer to the object type.

  The syntax of an object type defines the abstract data structure
  corresponding to that object type.  The ASN.1 language is used for
  this purpose.  However, the SMI [3] purposely restricts the ASN.1
  constructs which may be used.  These restrictions are explicitly made
  for simplicity.

  The encoding of an object type is simply how that object type is
  represented using the object type's syntax.  Implicitly tied to the
  notion of an object type's syntax and encoding is how the object type
  is represented when being transmitted on the network.

  This SMI specifies the use of the basic encoding rules of ASN.1 [8],
  subject to the additional requirements imposed by the SNMP.

3.1.  Format of Definitions

  The next section contains the specification of all object types
  contained in the MIB.  Following the conventions of the companion
  memo, the object types are defined using the following fields:

RFC 1162                        CLNS MIB                       June 1990


         OBJECT:
         -------
              A textual name, termed the OBJECT DESCRIPTOR, for the
              object type, along with its corresponding OBJECT
              IDENTIFIER.

         Syntax:
              The abstract syntax for the object type, presented using
              ASN.1.  This must resolve to an instance of the ASN.1
              type ObjectSyntax defined in the SMI.

         Definition:
              A textual description of the semantics of the object
              type.  Implementations should ensure that their
              interpretation of the object type fulfills this
              definition since this MIB is intended for use in multi-
              vendor environments.  As such it is vital that object
              types have consistent meaning across all machines.

         Access:
              A keyword, one of read-only, read-write, write-only, or
              not-accessible.  Note that this designation specifies the
              minimum level of support required.  As a local matter,
              implementations may support other access types (e.g., an
              implementation may elect to permitting writing a variable
              marked herein as read-only).  Further, protocol-specific
              "views" (e.g., those implied by an SNMP community) may
              make further restrictions on access to a variable.

         Status:
              A keyword, one of mandatory, optional, obsolete, or
              deprecated.  Use of deprecated implies mandatory status.

  These objects can be used when the ISO Connectionless-mode Network
  Protocol [9] and End System to Intermediate System [10] protocols are
  present. No assumptions are made as to what underlying protocol is
  being used to carry the SNMP.

  This memo uses the string encoding of [11] to textually describe OSI
  addresses.

  The ASN.1 type ClnpAddress is used to denote an OSI address.  This
  consists of a string of octets.  The first octet of the string
  contains a binary value in the range of 0..20, and indicates the the
  length in octets of the NSAP.  Following the first octet, is the
  NSAP, expressed in concrete binary notation, starting with the most
  significant octet.  A zero- length NSAP is used as a "special"
  address meaning "the default NSAP" (analogous to the IP address of
  0.0.0.0).  Such an NSAP is encoded as a single octet, containing the
  value 0.

  All other NSAPs are encoded in at least 2 octets.

6.  Identification of OBJECT instances for use with the SNMP

  The names for all object types in the MIB are defined explicitly
  either in the Internet-standard MIB or in other documents which
  conform to the naming conventions of the SMI.  The SMI requires that
  conformant management protocols define mechanisms for identifying
  individual instances of those object types for a particular network
  element.

  Each instance of any object type defined in the MIB is identified in
  SNMP operations by a unique name called its "variable name." In



Satz                                                           [Page 66]

RFC 1162                        CLNS MIB                       June 1990


  general, the name of an SNMP variable is an OBJECT IDENTIFIER of the
  form x.y, where x is the name of a non-aggregate object type defined
  in the MIB and y is an OBJECT IDENTIFIER fragment that, in a way
  specific to the named object type, identifies the desired instance.

  This naming strategy admits the fullest exploitation of the semantics
  of the powerful SNMP get-next operator, because it assigns names for
  related variables so as to be contiguous in the lexicographical
  ordering of all variable names known in the MIB.

  The type-specific naming of object instances is defined below for a
  number of classes of object types.  Instances of an object type to
  which none of the following naming conventions are applicable are
  named by OBJECT IDENTIFIERs of the form x.0, where x is the name of
  said object type in the MIB definition.

  For example, suppose one wanted to identify an instance of the
  variable sysDescr in the Internet-standard MIB.  The object class for
  sysDescr is:

     iso org dod internet mgmt mib system sysDescr
      1   3   6     1      2    1    1       1

  Hence, the object type, x, would be 1.3.6.1.2.1.1.1 to which is
  appended an instance sub-identifier of 0.  That is, 1.3.6.1.2.1.1.1.0
  identifies the one and only instance of sysDescr.

6.1.  clnpAddrTable Object Type Names

  The name of an CLNP-addressable network element, x, is the OBJECT
  IDENTIFIER of the form z such that z is the value (in which each
  octet of the ClnpAddress type is expressed as a sub-identifier of the
  OBJECT IDENTIFIER) of that instance of the clnpAdEntAddr object type
  associated with x.

  For each object type, t, for which the defined name, n, has a prefix
  of clnpAddrEntry, an instance, i, of t is named by an OBJECT
  IDENTIFIER of the form n.y, where y is the name of the CLNP-
  addressable network element about which i represents information.

  For example, suppose one wanted to find the maximum reassembly size
  of an entry in the CLNP interface table associated with an CLNP
  address of NS+0504030201.  Accordingly, clnpAdEntNetMask.5.5.4.3.2.1
  would identify the desired instance.

6.2.  clnpRoutingTable Object Type Names

  The name of an CLNP route, x, is the OBJECT IDENTIFIER of the form z



Satz                                                           [Page 67]

RFC 1162                        CLNS MIB                       June 1990


  such that z is the value (in which each octet of the ClnpAddress type
  is expressed as a sub-identifier of the OBJECT IDENTIFIER) of that
  instance of the clnpRouteDest object type associated with x.

  For each object type, t, for which the defined name, n, has a prefix
  of clnpRoutingEntry, an instance, i, of t is named by an OBJECT
  IDENTIFIER of the form n.y, where y is the name of the CLNP route
  about which i represents information.

  For example, suppose one wanted to find the next hop of an entry in
  the CLNP routing table associated  with the destination of
  NS+0504030201.  Accordingly, clnpRouteNextHop.5.5.4.3.2.1 would
  identify the desired instance.

  At the option of the agent, multiple routes to the same destination
  may be visible.  To realize this, the agent, while required to return
  a single entry for an CLNP route, x, of the form n.y, may also return
  information about other routes to the same destination using the form
  n.y.v, where v is a implementation-dependent small, non-negative
  integer.

6.3.  clnpNetToMediaTable Object Type Names

  The name of a cached CLNP address, x, is an OBJECT IDENTIFIER of the
  form s.z, such that s is the value of that instance of the
  clnpNetToMediaIfIndex object type associated with the entry and z is
  the value of the CLNP address of the clnpNetToMediaNetAddress object
  type associated with x, in which each octet of the ClnpAddress type
  is expressed as a sub-identifier of the OBJECT IDENTIFIER.

  For each object type, t, for which the defined name, n, has a prefix
  of clnpNetToMediaEntry, an instance, i, of t is named by an OBJECT
  IDENTIFIER of the form n.y, where y is the name of the cached CLNP
  address about which i represents information.

  For example, suppose one wanted to find the media address of an entry
  in the address translation table associated with a CLNP address of
  NS+0504030201 and interface 3.  Accordingly,
  clnpNetToMediaPhysAddress.3.5.5.4.3.2.1 would identify the desired
  instance.

6.4.  clnpMediaToNetTable Object Type Names

  The name of a cached media address, x, is an OBJECT IDENTIFIER of the
  form s.z, such that s is the value of that instance of the
  clnpMediaToNetIfIndex object type associated with the entry and z is
  the value of the media address of the clnpMediaToNetMediaAddress
  object type associated with x, in which each octet of the media

  address is expressed as a sub- identifier of the OBJECT IDENTIFIER.

  For each object type, t, for which the defined name, n, has a prefix
  of clnpMediaToNetEntry, an instance, i, of t is named by an OBJECT
  IDENTIFIER of the form n.y, where y is the name of the cached media
  address about which i represents information.

  For example, suppose one wanted to find the CLNP address of an entry
  in the address translation table associated with a media address of
  08:00:20:00:38:ba and interface 3.  Accordingly,
  clnpMediaToNetNetAddress.3.8.0.32.0.56.186 would identify the desired
  instance.
