`Abstract:
`The media access control characteristics for the Carrier Sense Multiple Access with Collision De-
`tection (CSMA/CD) access method for shared medium local area networks are described. The control charac-
`teristics for full duplex dedicated channel use are also described. Specifications are provided for MAU types
`1BASE5 at 1 Mb/s; Attachment Unit Interface (AUI) and MAU types 10BASE5, 10BASE2, FOIRL (fiber optic
`inter-repeater link), 10BROAD36, 10BASE-T, 10BASE-FL, 10BASE-FB, and 10BASE-FP at 10 Mb/s; Media
`Independent Interface (MII) and PHY types 100BASE-T4, 100BASE-TX, 100BASE-FX, and 100BASE-T2 at
`100 Mb/s; and the Gigabit MII (GMII) and 1000BASE-X PHY types, 1000BASE-SX, 1000BASE-LX, and
`1000BASE-CX, which operate at 1000 Mb/s (Gigabit Ethernet) as well as PHY type 1000BASE-T. Repeater
`specifications are provided at each speed. Full duplex specifications are provided at the Physical Layer for
`10BASE-T, 10BASE-FL, 100BASE-TX, 100BASE-FX, 100BASE-T2, and Gigabit Ethernet. System consider-
`ations for multisegment networks at each speed and management information base (MIB) specifications and
`additions to support Virtual Bridged Local Area Networks (VLANs) as specified in IEEE P802.1Q are also pro-
`vided. Also specified is an optional Link Aggregation sublayer which multiple physical links to be aggregated
`together to form a single logical link.

`
`IEEE Standards
` documents are developed within the IEEE Societies and the Standards Coordinat-
`ing Committees of the IEEE Standards Association (IEEE-SA) Standards Board. Members of the
`committees serve voluntarily and without compensation. They are not necessarily members of the
`Institute. 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-
`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-
`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-
`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
`societies and Standards Coordinating 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 patents for
`which a license may be required by an IEEE standard or for conducting inquiries into
`the legal validity or scope of those patents that are brought to its attention.

`Authorization to photocopy portions of any individual standard for internal or personal use is

`room use can also be obtained through the Copyright Clearance Center.

`
`This family of standards deals with the Physical and Data Link layers as defined by the International
`Organization for Standardization (ISO) Open Systems Interconnection (OSI) Basic Reference Model
`(ISO/IEC 7498-1: 1994). The access standards define seven types of medium access technologies and
`associated physical media, each appropriate for particular applications or system objectives. Other types are
`under investigation.
`
`The standards defining the technologies noted above are as follows:
`
`•
`
`IEEE Std 802
`
` This standard provides an overview to the
`Overview and Architecture.
`family of IEEE 802 Standards.
`
`• ANSI/IEEE Std 802.1B
`and 802.1k
`[ISO/IEC 15802-2]
`
` Defines an OSI management-compatible
`LAN/MAN Management.
`architecture, and services and protocol elements for use in a LAN/MAN
`environment for performing remote management.
`
`• ANSI/IEEE Std 802.1D
`
`
` Specifies an architecture and protocol
`Media Access Control
`(MAC) Bridges.
`for the interconnection of IEEE 802 LANs below the MAC service boundary.
`
`• ANSI/IEEE Std 802.1E
`[ISO/IEC 15802-4]
`
` Specifies a set of services and protocol for those aspects
`System Load Protocol.
`of management concerned with the loading of systems on IEEE 802 LANs.

`.
`Common Definitions and Procedures for IEEE 802 Management Information

`
`
`. Specifies extensions for the
`Remote Media Access Control
`(MAC) Bridging
`interconnection, using non-LAN communication technologies, of geographically
`separated IEEE 802 LANs below the level of the logical link control protocol.
`
`•
`
`IEEE Std 802.1H
