Subject: updated fddi mib draft

    Here's the new FDDI MIB draft, updated as per the changes sent out
    earlier plus some minor editorial updates.

    I'm told that once the SMT standard is published, it would be titled
    ANSI X3.229 (with perhaps a different rev yet) -- and 7.3, used only
    to reflect the current working draft, would become but a faint memory.
    So, we may be better off getting rid of the 73 in the "smt73" prefix.
    For the time being I have left it at the latter; this can be tweaked
    prior to RFC publication.

    Other than that, the MIB is mostly done.  If there are any further
    comments, please send them to this list within the next 2 weeks.

          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,
          as specified in the ANSI SMT 7.3 draft standard.

          This memo does not specify a standard for the Internet
          community.

          3.  Historical Perspective

          As reported in RFC 1052, IAB Recommendations for the
          Development of Internet Network Management Standards [1], a
          two-prong strategy for network management of TCP/IP-based
          internets was undertaken.  In the short-term, the Simple
          Network Management Protocol (SNMP), defined in RFC 1067, was
          to be used to manage nodes in the Internet community.  In the
          long-term, the use of the OSI network management framework was
          to be examined.  Two documents were produced to define the
          management information: RFC 1065, which defined the Structure
          of Management Information (SMI), and RFC 1066, which defined
          the Management Information Base (MIB).  Both of these
          documents were designed so as to be compatible with both the
          SNMP and the OSI network management framework.

          This strategy was quite successful in the short-term:
          Internet-based network management technology was fielded, by
          both the research and commercial communities, within a few
          months.  As a result of this, portions of the Internet
          community became network manageable in a timely fashion.

          As reported in RFC 1109, Report of the Second Ad Hoc Network
          Management Review Group [2], the requirements of the SNMP and
          the OSI network management frameworks were more different than
          anticipated.  As such, the requirement for compatibility
          between the SMI/MIB and both frameworks was suspended.  This
          action permitted the operational network management framework,
          based on the SNMP, to respond to new operational needs in the
          Internet community by producing MIB-II.

          In May of 1990, the core documents were elevated to "Standard
          Protocols" with "Recommended" status.  As such, the Internet-
          standard network management framework consists of: Structure
          and Identification of Management Information for TCP/IP-based
          internets, RFC 1155 [3], which describes how managed objects
          contained in the MIB are defined; Management Information Base
          for Network Management of TCP/IP-based internets, which
          describes the managed objects contained in the MIB, RFC 1156
          [4]; and, the Simple Network Management Protocol, RFC 1157
          [5], which defines the protocol used to manage these objects.

          Consistent with the IAB directive to produce simple, workable
          systems in the short-term, the list of managed objects defined
          in the Internet-standard MIB was derived by taking only those

          elements which are considered essential.  However, the SMI
          defined three extensibility mechanisms: one, the addition of
          new standard objects through the definitions of new versions
          of the MIB; two, the addition of widely-available but non-
          standard objects through the experimental subtree; and three,
          the addition of private objects through the enterprises
          subtree.  Such additional objects can not only be used for
          vendor-specific elements, but also for experimentation as
          required to further the knowledge of which other objects are
          essential.

          This memo defines extensions to the MIB using the second
          method.  It contains definitions of managed objects used for
          experimentation.

          4.  Objects

          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) [5] defined in the SMI.  In particular, each
          object has a name, a syntax, and an encoding.  The name is an
          object identifier, an administratively assigned name, which
          specifies an object type.  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 OBJECT DESCRIPTOR, to also
          refer to the object type.

          The syntax of an object type defines the abstract data
          structure corresponding to that object type.  The ASN.1
          language is used for this purpose.  However, the SMI [1]
          purposely restricts the ASN.1 constructs which may be used.
          These restrictions are explicitly made for simplicity.

          The encoding of an object type is simply how that object type
          is represented using the object type's syntax.  Implicitly
          tied to the notion of an object type's syntax and encoding is
          how the object type is represented when being transmitted on
          the network.

          The SMI specifies the use of the basic encoding rules of ASN.1
          [6], subject to the additional requirements imposed by the
          SNMP.


          4.1.  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                 March 1993


          5.  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:

               smt73    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.

          5.1.  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.


          6.  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.
