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.

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.

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.

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].

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 ::= { 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.

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.

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

assumptions should be made about compatibility with RFC 1285.

                  "A value representing the connection policies in
                  effect in a node. A station sets the corresponding
                  bit for each of the connection types that it
                  rejects. The letter designations, X and Y, in the
                  'rejectX-Y' names have the following significance:
                  X represents the PC-Type of the local PORT and Y
                  represents the PC_Type of the adjacent PORT
                  (PC_Neighbor). The evaluation of Connection-
                  Policy (PC-Type, PC-Neighbor) is done to determine
                  the setting of T- Val(3) in the PC-Signalling
                  sequence (refer to ANSI 9.6.3). Note that Bit 15,
