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.
