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.

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.

4. Object Definitions

  1. - This MIB module uses the extended OBJECT-TYPE macro as
  2. - defined in [7].

  1. - 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.

        -- where the first octet contains the first 8 bits of the
        -- address, with the I/G(Individual/Group) address bit as the
        -- least significant bit and the  U/L (Universal/Local) bit
        -- as the next more significant bit, and so on.  Note that
