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 Coordinating Committees of
the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus
development process, approved by the American National Standards Institute, which brings together volunteers repre-
senting varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the
Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote
fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy
of any of the information contained in its standards or implementations thereof.
Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other
damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly
resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document.
The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly dis-
claims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific pur-
pose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents are
supplied “
AS IS
.”
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 scheduled for 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.
In publishing and making this document available, the IEEE is not suggesting or rendering professional or other ser-
vices for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other per-
son or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the
advice of a competent professional in determining the exercise of reasonable care in any given circumstances.
Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to spe-
cific 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 represent a consensus of 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 inter-
pretation requests except in those cases where the matter has previously received formal consideration.

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. Comments on standards and requests for interpretations should be addressed to:

Introduction to IEEE Std 802.3-2002
This standard is part of a family of standards for local and metropolitan area networks. The relationship
between the standard and other members of the family is shown below. (The numbers in the figure refer to
IEEE standard numbers.

)
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:
