          This draft document will be submitted to the RFC editor as an
          experimental extension to the SNMP MIB.  It is anticipated
          that a subsequent version of this memo will eventually
          supersede RFC 1285.  Distribution of this memo is unlimited.

          2.  Abstract
          
          This memo defines an experimental 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.
          
          This memo does not specify a standard for the Internet
          community.

          3.  The Network Management Framework
          
          The Internet-standard Network Management Framework consists of
          three components.  They are:
          
          o    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.
          
          o    RFC 1213 defines MIB-II, the core set of managed objects
               for the Internet suite of protocols.
          
          o    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.
          
          
          3.1.  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.
          
          
          3.2.  Format of Definitions
          
          Section 6 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].

          Internet Draft             FDDI MIB                   May 1993
          
          
          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:
          
               fddimib    OBJECT IDENTIFIER ::= { experimental 8 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.

          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 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.
          
          
          5.  Changes from RFC-1285
          
          The changes from RFC-1285 to this document, based on changes
          from ANSI SMT 6.2 to SMT 7.3, were so numerous that this MIB
          is located on a different branch of the MIB tree.  No
          assumptions should be made about compatibility with RFC-1285.

                      X represents the PC-Type of the local PORT and Y
                      represents the PC_Type of the adjacent PORT
