`

`
`IEEE Standards documents are developed within the Technical Committees of the IEEE Societies
`and the Standards Coordinating Committees of the IEEE Standards Board. Members of the com(cid:173)
`mittees serve voluntarily and without compensation. They are not necessarily members of the Insti(cid:173)
`tute. The standards developed within IEEE represent a consensus of the broad expertise on the
`subject within the Institute as well as those activities outside of IEEE that have expressed an inter(cid:173)
`est in participating in the development of the standard.
`
`Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply
`that there are no other ways to produce, test, measure, purchase, market, or provide other goods and
`services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the
`time a standard is approved and issued is subject to change brought about through developments in
`the state of the art and comments received from users of the standard. Every IEEE Standard is sub(cid:173)
`jected to review at least every five years for revision or reaffirmation. When a document is more
`than five years old and has not been reaffirmed, it is reasonable to conclude that its contents,
`although still of some value, do not wholly reflect the present state of the art. Users are cautioned to
`check to determine that they have the latest edition of any IEEE Standard.
`
`Comments for revision of IEEE Standards are welcome from any interested party, regardless of
`membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a
`proposed change of text, together with appropriate supporting comments.
`
`Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as
`they relate to specific applications. When the need for interpretations is brought to the attention of
`IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards rep(cid:173)
`resent a consensus of all concerned interests, it is important to ensure that any interpretation has
`also received the concurrence of a balance of interests. For this reason IEEE and the members of its
`technical committees are not able to provide an instant response to interpretation requests except in
`those cases where the matter has previously received formal consideration.
`
`Comments on standards and requests for interpretations should be addressed to:

`
`Note: Attention is called to the possibility that implementation of this standard may
`require use of subject matter covered by patent rights. By publication of this standard,
`no position is taken with respect to the existence or validity of any patent rights in
`connection therewith. The IEEE shall not be responsible for identifying all patents for
`which a license may be required by an IEEE standard or for conducting inquiries into
`the legal validity or scope ofthose patents that are brought to its attention.
`
`Authorization to photocopy portions of any individual standard for internal or personal use is
`granted by the Institute of Electrical and Electronics Engineers, Inc., provided that the appropriate

`*Formerly IEEE Sid 802.1A.
`
`This family of standards deals with the Physical and Data Link layers as defined by the International Organi(cid:173)
`zation for Standardization (ISO) Open Systems Interconnection Basic Reference Model (ISO 7498 : 1984).
`The access standards define several types of medium access teclmologies and associated physical media,
`each appropriate for particular applications or system objectives. Other types are under iiWestigation.
`
`The standards defining the teclmologies noted above are as follows:
`
`• IEEE Std 802 1
`
`:
`
`• ANSI/IEEE Std 802.1B
`[ISO/IEC 15802-2]:
`
`• ANSI/IEEE Std 802.1D
`[ISO/IEC 10038]:
`
`• ANSI/IEEE Std 802.1E
`[ISO/IEC 15802-4]:
`
`Overview and Architecture. This standard provides an over(cid:173)
`view to the family of IEEE 802 Standards. This document
`forms part of the 802.1 scope of work.
`
`LAN/MAN Management. Defines an Open Systems
`Interconnection (OSI) management-compatible architecture,
`and services and protocol elements for use in a LAN/MAN
`eiWironment for performing remote management.
`
`MAC Bridging. Specifies an architecture and protocol for the
`interconnection of IEEE 802 LAN s below the MAC service
`boundary.
`
`System Load Protocol. Specifies a set of services and protocol
`for those aspects of management concerned with the loading of
`systems on IEEE 802 LANs.
`
`1The 802 Architecture and Overview standard, originally known as IEEE Std 802.1A, has been renumbered as IEEE Std 802. This has
`been done to accommodate recognition of the base standard in a family of standards. References to IEEE Std S02.1A should be consid(cid:173)
`ered as references to IEEE Std 802.

`
`The following additional working groups have authorized standards projects under development:

`• IEEE 802.11:
`
`• IEEE 802.14:
`
`Wireless LAN Medium Access Control (MAC) Sublayer and
`Physical Layer Specifications
`
`Standard Protocol for Cable-TV Based Broadband
`Communication Network
`
`The reader of this standard is urged to become familiar with the complete family of standards.
`
`Conformance test methodology
`
`An additional standards series, identified by the number 1802, has been established to identify the
`conformance test methodology documents for the 802 family of standards. Thus the conformance test
`documents for 802.3 are numbered 1802.3, the conformance test documents for 802.5 will be 1802.5, and so
`on. Similarly, ISO will use 18802 to number conformance test standards for 8802 standards.

`
`IEEE Std 802.3u-1995
`
`At the time this standard (IEEE Std 802.3u-1995) was published, the IEEE 802.3 standard consisted of the
`following published documents:
`
`ISO/IEC 8802-3: 1993 [ANSI/IEEE Std 802.3, 1993 Edition]
`IEEE Std 802.3j-1993, Fiber Optic Active and Passive Star-Based Segments, Type IOBASE-F
`(Clauses 15-18)
`IEEE Std 802.3k-1992, Layer Management for lO lVIb/s Baseband Repeaters (Clause 19)
`IEEE Std 802.31-1992, Type lOBASE-T Protocol Implementation Conformance Statement (PICS)
`Proforma (Subclause 14.10)
`IEEE Std 802.3p-1993 and IEEE Std 802.3q-1993, Guidelines for the Development of Managed
`Objects (GDMO) (ISO/IEC 10165-4) Format for Layer-Managed Objects (Clause 5) and Layer
`Management for 10 JVIb/s Baseband Medium Attachment Units (MAU s) (Clause 20)
`IEEE Std 1802.3d-1993, Type lOBASE-T Medium Attachment Unit (MAU) (Conformance Test
`Methodology (Clause 6)
`
`At the time this standard was published, there was revision and supplementary material that had been
`approved and scheduled for publication. Also, a new edition of ISO/IEC 8802-3 was in preparation to con(cid:173)
`solidate a significant amount of the above material. Information on the current state of this and other IEEE
`802 standards may be obtained from

`Patent information
`
`The IEEE Standards Board calls attention to the fact that it is claimed that portions of IEEE Std 802.3u-1995
`are the subject of patents owned by a number of companies. The IEEE takes no position with respect to
`patent validity. Each of these companies has assured IEEE that it is willing to grant a license on these patents
`on reasonable and nondiscriminatory terms to anyone wishing to obtain such a license. The undertakings of
`these companies in this respect are on file with the IEEE Standards Department, and the license details may
`be obtained by contacting the Standards Department.
