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.

RFC 1162 CLNS MIB June 1990
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
Satz [Page 2]
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:
Satz [Page 3]
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.
4. Object Definitions
CLNS-MIB DEFINITIONS ::= BEGIN
IMPORTS
experimental, OBJECT-TYPE, Counter
FROM RFC1155-SMI;
-- new type of NetworkAddress
ClnpAddress ::=
[APPLICATION 5]
IMPLICIT OCTET STRING (SIZE (1..21))
Satz [Page 4]
RFC 1162 CLNS MIB June 1990
clns OBJECT IDENTIFIER ::= { experimental 1 }
clnp OBJECT IDENTIFIER ::= { clns 1 }
error OBJECT IDENTIFIER ::= { clns 2 }
echo OBJECT IDENTIFIER ::= { clns 3 }
es-is OBJECT IDENTIFIER ::= { clns 4 }
END
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.

}
Definition:
The type of mapping.
Setting this object to the value invalid(2) has the effect of
invalidating the corresponding entry in the
clnpMediaToNetTable. That is, it effectively dissassociates
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 clnpMediaToNetType object.

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
Satz [Page 68]
RFC 1162 CLNS MIB June 1990
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.
