                              CLNS MIB
                            for use with
             Connectionless Network Protocol (ISO 8473)
                                and
            End System to Intermediate System (ISO 9542)

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 is an Experimental Protocol for the
 Internet community.  Discussion and suggestions for improvement are
 requested.  Please refer to the current edition of the "IAB Official
 Protocol Standards" for the standardization state and status of this
 protocol.  Distribution of this memo is unlimited.

1. The Network Management Framework

 The Internet-standard Network Management Framework consists of three
 components.  They are:
    RFC 1155 which defines the SMI, the mechanisms used for describing
    and naming objects for the purpose of management.  RFC 1212
    defines a more concise description mechanism, which is wholly
    consistent with the SMI.

Satz [Page 1] RFC 1238 CLNS MIB June 1991

    RFC 1156 which defines MIB-I, the core set of managed objects for
    the Internet suite of protocols.  RFC 1213, defines MIB-II, an
    evolution of MIB-I based on implementation experience and new
    operational requirements.
    RFC 1157 which defines the SNMP, the protocol used for network
    access to managed objects.
 The Framework permits new objects to be defined for the purpose of
 experimentation and evaluation.

2. 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.
 The SMI specifies the use of the basic encoding rules of ASN.1 [8],
 subject to the additional requirements imposed by the SNMP.

2.1. Format of Definitions

 Section 4 contains the specification of all object types contained in
 this MIB module.  The object types are defined using the conventions
 defined in the SMI, as amended by the extensions specified in [9].

3. Overview

 The objects defined in this MIB module are be used when the ISO
 Connectionless-mode Network Protocol [10] and End System to

Satz [Page 2] RFC 1238 CLNS MIB June 1991

 Intermediate System [11] 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 [12] to textually describe OSI
 addresses.

3.1. Textual Conventions

 A new data type is introduced as a textual convention in this MIB
 document.  This textual conventions enhance the readability of the
 specification and can ease comparison with other specifications if
 appropriate.  It should be noted that the introduction of this
 textual convention has no effect on either the syntax nor the
 semantics of any managed objects.  The use of this is merely an
 artifact of the explanatory method used.  Objects defined in terms of
 this methods are always encoded by means of the rules that define the
 primitive type.  Hence, no changes to the SMI or the SNMP are
 necessary to accommodate this textual convention which are adopted
 merely for the convenience of readers and writers in pursuit of the
 elusive goal of clear, concise, and unambiguous MIB documents.
 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 4 octets.

3.2. Changes from RFC 1162

 Features of this MIB include:
    (1)  The managed objects in this document have been defined
         using the conventions defined in the Internet-standard
         SMI, as amended by the extensions specified in [9].  It
         must be emphasized that definitions made using these
         extensions are semantically identically to those in RFC
         1162.
    (2)  The PhysAddress textual convention from MIB-II has been
         introduced to represent media addresses.
    (3)  The clnpRoutingDiscards, clnpRouteMetric5, and
         clnpRouteInfo objects have been defined.

Satz [Page 3] RFC 1238 CLNS MIB June 1991

    (4)  The ClnpAddress type was mistakenly given a tag in RFC
         1162.  This error has been corrected.
