FDDI Management Information Base

Status of this Memo

This RFCspecifies 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, RFC1155 which defines the SMI, the mechanisms used for

describing and naming objects for the purpose of

management. STD 16, RFC1212 defines a more concise description

mechanism, which is wholly consistent with the SMI.

o STD 17, RFC1213 defines MIB-II, the core set of managed objects

for the Internet suite of protocols.

o STD 15, RFC1157 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

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 RFC1285

The changes from RFC1285 [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 RFC1285.

4. Object Definitions

FDDI-SMT73-MIB DEFINITIONS ::= BEGIN

IMPORTS

Counter

FROM RFC1155-SMI

OBJECT-TYPE

FROM RFC-1212;

-- This MIB module uses the extended OBJECT-TYPE macro as

-- defined in [7].

-- this is the FDDI MIB module

fddi OBJECT IDENTIFIER ::= { transmission 15 }

fddimib OBJECT IDENTIFIER ::= { fddi 73 }

-- 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.

FddiTimeMilli ::= INTEGER (0..2147483647)

-- This data type is used for some FDDI timers. It specifies

-- time in 1 millisecond units, in normal integer

-- representation.

FddiResourceId ::= INTEGER (0..65535)

-- This data type is used to refer to an instance of a MAC,

-- PORT, or PATH Resource ID. Indexing begins

-- at 1. Zero is used to indicate the absence of a resource.

FddiSMTStationIdType ::= OCTET STRING (SIZE (8))

-- The unique identifier for the FDDI station. This is a

-- string of 8 octets, represented as X' yy yy xx xx xx xx

-- xx xx' with the low order 6 octet (xx) from a unique IEEE

-- assigned address. The high order two bits of the IEEE

-- address, the group address bit and the administration bit

-- (Universal/Local) bit should both be zero. The first two

-- octets, the yy octets, are implementor-defined.

--

-- The representation of the address portion of the station id

-- is in the IEEE (ANSI/IEEE P802.1A) canonical notation for

-- 48 bit addresses. The canonical form is a 6-octet string

-- 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

-- addresses in the ANSI FDDI standard SMT frames are

-- represented in FDDI MAC order.

FddiMACLongAddressType ::= OCTET STRING (SIZE (6))

-- The representation of long MAC addresses as management

-- values is in the IEEE (ANSI/IEEE P802.1A) canonical

-- notation for 48 bit addresses. The canonical form is a

-- 6-octet string 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 the addresses in the SMT frames are

-- represented in FDDI MAC order.
