+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.

+
+ fddi OBJECT IDENTIFIER ::= { transmission 15 }
+ fddimib OBJECT IDENTIFIER ::= { fddi 73 }
+
+
+ -- textual conventions
+
+ 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.

+ --
+ -- The representation of the address portion of the station id
+ -- is in the IEEE (ANSI/IEEE P802.1A) canonical notation for
