Abstract: The media access control characteristics for the Carrier Sense Multiple Access with Collision Detection (CS-MA/CD) access method for shared medium local area networks are described. The control characteristics for full duplexdedicated channel use are also described. Specifications are provided for MAU types 1BASE5 at 1 Mb/s; Attachment UnitInterface (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 PHYtypes, 1000BASE-SX, 1000BASE-LX, and 1000BASE-CX, which operate at 1000 Mb/s (Gigabit Ethernet) as well asPHY type 1000BASE-T. Repeater specifications are provided at each speed. Full duplex specifications are provided atthe Physical Layer for 10BASE-T, 10BASE-FL, 100BASE-TX, 100BASE-FX, 100BASE-T2, and Gigabit Ethernet.

IEEE Standards

documents are developed within the IEEE Societies and the Standards Coordinating Committees ofthe IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensusdevelopment 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 theInstitute and serve without compensation. While the IEEE administers the process and establishes rules to promotefairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracyof 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 otherdamage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectlyresulting 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 aresupplied “

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 viewpointexpressed at the time a standard is approved and issued is subject to change brought about through developments in thestate of the art and comments received from users of the standard. Every IEEE Standard is scheduled for review at leastevery 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 theart. 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 theadvice 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 actionto prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important toensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and themembers 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 affiliationwith IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together withappropriate supporting comments.

Introduction to IEEE Std 802.3-2002

This standard is part of a family of standards for local and metropolitan area networks. The relationshipbetween the standard and other members of the family is shown below. (The numbers in the figure refer toIEEE standard numbers.1)

This family of standards deals with the Physical and Data Link layers as defined by the InternationalOrganization 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 andassociated physical media, each appropriate for particular applications or system objectives. Other types areunder investigation.

The standards defining the technologies noted above are as follows:

Part 3: Carrier Sense Multiple Access with Collision Detection (CSMA/CD) access method and physical layer specifications

SECTION ONE: This section includes Clauses 1 through 20 and Annexes A through H.

1. Introduction

1.1 Overview

This is a comprehensive International Standard for Local Area Networks (LANs) employing CSMA/CD asthe access method. This International Standard is intended to encompass several media types and techniquesfor signal rates from 1 Mb/s to 1000 Mb/s. This edition of the standard provides the necessary specificationsfor the following families of systems: a 1 Mb/s baseband system, 10 Mb/s baseband and broadband systems,a 100 Mb/s baseband system, and a 1000 Mb/s baseband system. In addition, it specifies a method for lin-early incrementing a system’s data rate by aggregating multiple physical links of the same speed into onelogical link.

1.1.1 Basic concepts

This standard provides for two distinct modes of operation: half duplex and full duplex. A given IEEE 802.3instantiation operates in either half or full duplex mode at any one time. The term “CSMA/CD MAC” is usedthroughout this standard synonymously with “802.3 MAC,” and may represent an instance of either a halfduplex or full duplex mode data terminal equipment (DTE), even though full duplex mode DTEs do notimplement the CSMA/CD algorithms traditionally used to arbitrate access to shared-media LANs.

1.1.1.1 Half duplex operation

In half duplex mode, the CSMA/CD media access method is the means by which two or more stations sharea common transmission medium. To transmit, a station waits (defers) for a quiet period on the medium (thatis, no other station is transmitting) and then sends the intended message in bit-serial form. If, after initiatinga transmission, the message collides with that of another station, then each transmitting station intentionallytransmits for an additional predefined period to ensure propagation of the collision throughout the system.The station remains silent for a random amount of time (backoff) before attempting to transmit again. Eachaspect of this access method process is specified in detail in subsequent clauses of this standard.

Half duplex operation can be used with all media and configurations allowed by this standard.

1.1.1.2 Full duplex operation

Full duplex operation allows simultaneous communication between a pair of stations using point-to-pointmedia (dedicated channel). Full duplex operation does not require that transmitters defer, nor do they moni-tor or react to receive activity, as there is no contention for a shared medium in this mode. Full duplex modecan only be used when all of the following are true:

a) The physical medium is capable of supporting simultaneous transmission and reception withoutinterference.

b) There are exactly two stations connected with a full duplex point-to-point link. Since there is no con-tention for use of a shared medium, the multiple access (i.e., CSMA/CD) algorithms are unnecessary.

c) Both stations on the LAN are capable of, and have been configured to use, full duplex operation.

The most common configuration envisioned for full duplex operation consists of a central bridge (alsoknown as a switch) with a dedicated LAN connect
