1. Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in TCP/IP-based internets.
In particular, it defines objects for managing devices which
implement the FDDI.
2. The Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
Case [Page 1]
RFC 1285 FDDI MIB January 1992
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.
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.
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) [5]
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 [1] 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 [6],
subject to the additional requirements imposed by the SNMP.
3.1. Format of Definitions
Section 5 contains 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
Case [Page 2]
RFC 1285 FDDI MIB January 1992
specified in [7].
4. Overview
This document defines the managed objects for FDDI devices which are
to be accessible via the Simple Network Management Protocol (SNMP).
At present, this applies to these values of the ifType variable in
the Internet-standard MIB:
fddi(15)
For these interfaces, the value of the ifSpecific variable in the
MIB-II [4] has the OBJECT IDENTIFIER value:
fddi OBJECT IDENTIFIER ::= { transmission 15 }
The definitions of the objects presented here draws heavily from
related work in the ANSI X3T9.5 committee and the SMT subcommittee of
that committee [8]. In fact, the definitions of the managed objects
in this document are, to the maximum extent possible, identical to
those identified by the ANSI committee. The semantics of each
managed object should be the same with syntactic changes made as
necessary to recast the objects in terms of the Internet-standard SMI
and MIB so as to be compatible with the SNMP. Examples of these
syntactic changes include remapping booleans to enumerated integers,
remapping bit strings to octet strings, and the like. In addition,
the naming of the objects was changed to achieve compatibility.
These minimal syntactic changes with no semantic changes should allow
implementations of SNMP manageable FDDI systems to share
instrumentation with other network management schemes and thereby
minimize implementation cost. In addition, the translation of
information conveyed by managed objects from one network management
scheme to another is eased by these shared definitions.
Only the essential variables, as indicated by their mandatory status
in the ANSI specification were retained in this document. The
importance of variables which have an optional status in the ANSI
specification were perceived as being less widely accepted.
4.1. Textual Conventions
Several new datatypes are introduced as a textual convention in this
MIB document. These textual conventions enhance the readability of
the document and ease comparisons with its ANSI counterpart. It
should be noted that the introduction of the following textual
conventions has no effect on either the syntax nor the semantics of
any managed objects. The use of these is merely an artifact of the
Case [Page 3]
RFC 1285 FDDI MIB January 1992
explanatory method used. Objects defined in terms of one of these
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 these textual conventions which are adopted
merely for the convenience of readers and writers in pursuit of the
elusive goal of clear, concise, and unambiguous MIB documents.

Path-Test: Initiates a station path test.
The Path_Test variable (See ANSI Ref. 9.4.1) is
set to Testing. The results of this action are

"This object, when read, always returns a value of

to each of the acceptable values is as follows:
Other: Results in a badValue error.
maintPORT: Signal PC_Maint
enablePORT: Signal PC_Enable
disablePORT: Signal PC_Disable
startPORT: Signal PC_Start

Signals cause an SM_CM_CONTROL.request service to
be generated with a control_action of `Signal' and
the `variable' parameter set with the appropriate
value (i.e., PC_Maint, PC_Enable, PC_Disable,
PC_Start, PC_Stop). Ref. ANSI SMT Section 9.3.2.
Attempts to set this object to all other values
results in a badValue error."

DESCRIPTION
"An ATTACHMENT entry containing information common
to a given set of ATTACHMENTs.
The ATTACHMENT Resource represents a PORT or a
pair of PORTs plus the optional associated optical
bypass that are managed as a functional unit.
Because of its relationship to the PORT Objects,
there is a natural association of ATTACHMENT
Resource Indices to the PORT Indices. The
resource index for the ATTACHMENT is equal to the
associated PORT index for 'single-attachment' and
'concentrator' type snmpFddiATTACHMENTClasses.
For 'dual-attachment' Classes, the ATTACHMENT
Index is the PORT Index of the A PORT of the A/B
PORT Pair that represents the ATTACHMENT."
