FDDI Management Information Base
Status of this Memo
This RFC specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" for the standardization state and status
of this protocol. Distribution of this memo is unlimited.
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 based on the ANSI FDDI SMT 7.3 draft standard [8],
which has been forwarded for publication by the X3T9.5 committee.

RFC 1512 FDDI MIB September 1993
1. The Network Management Framework
The Internet-standard Network Management Framework consists of three
components. They are:
o STD 16, RFC 1155 which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of
management. STD 16, RFC 1212 defines a more concise description
mechanism, which is wholly consistent with the SMI.
o STD 17, RFC 1213 defines MIB-II, the core set of managed objects
for the Internet suite of protocols.
o STD 15, 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.
1.1. Object Definitions
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)
defined in the SMI. In particular, each object object type is named
by an OBJECT IDENTIFIER, an administratively assigned name. 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 descriptor, to
refer to the object type.
1.2. Format of Definitions
Section 4 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
specified in [7].
2. 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
Case & Rijsinghani [Page 2]
RFC 1512 FDDI MIB September 1993
MIB-II [4] has the OBJECT IDENTIFIER value:
fddimib OBJECT IDENTIFIER ::= { fddi 73 }
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.
2.1. 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 these textual conventions
has no effect on either the syntax or the semantics of any managed
objects. The use of these is merely an artifact of the 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.
3. Changes from RFC 1285
The changes from RFC 1285 [2] to this document, based on changes from
ANSI SMT 6.2 to SMT 7.3, were so numerous that the objects in this
MIB module are located on a different branch of the MIB tree. No
Case & Rijsinghani [Page 3]
RFC 1512 FDDI MIB September 1993
assumptions should be made about compatibility with RFC 1285.

FddiTimeNano ::= INTEGER (0..2147483647)
-- This data type specifies 1 nanosecond units as
-- an integer value.
--
-- NOTE: The encoding is normal integer representation, not
-- two's complement. Since this type is used for variables
-- which are encoded as TimerTwosComplement in the ANSI
-- specification, two operations need to be performed on such
-- variables to convert from ANSI form to SNMP form:
--
-- 1) Convert from two's complement to normal integer
-- representation
-- 2) Multiply by 80 to convert from 80 nsec to 1 nsec units
--
-- No resolution is lost. Moreover, the objects for which
-- this data type is used effectively do not lose any range
-- due to the lower maximum value since they do not require
-- the full range.
--
-- Example: If fddimibMACTReq had a value of 8 ms, it would
-- be stored in ANSI TimerTwosComplement format as 0xFFFE7960
-- [8 ms is 100000 in 80 nsec units, which is then converted
-- to two's complement] but be reported as 8000000 in SNMP
-- since it is encoded here as FddiTimeNano.

-- octets, the yy octets, are implementor-defined.
--
-- The representation of the address portion of the station id
