    There are two pertinent MIBs, apart from the basic MIB-II.  RFC-1512,
    the FDDI MIB, and the DEC Extended Vendor MIB.  I've posted both as
    replies to this note.

                    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

          fddi    OBJECT IDENTIFIER ::= { transmission 15 }

          --
          -- 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.

    1.  Introduction

    This memo describes the ELAN group of objects implemented on some
    Digital Equipment Corporation products.  These comprise extensions
    to the FDDI MIB, the system and interfaces groups in MIB-II, and
    the Bridge MIB.  Where possible, objects are reported under the
    standard MIBs.

    2.  Object Groupings

    The DEC Enterprise subtree is used to represent this group of
    objects as represented below.
