Ethernet local area network operation is specified for selected speeds of operationfrom 1 Mb/s to 10 Gb/s using a common media access control (MAC) specification, managementinformation base (MIB), and capability for Link Aggregation of multiple physical links into a singlelogical link. The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocolspecifies shared medium (half duplex) operation, as well as full duplex operation. Speed specificMedia Independent Interfaces (MIIs) allow use of selected physical layer (PHY) interfaces foroperation over coxial, twisted pair or fiber optic cables. System considerations for multisegmentshared access networks describe the use of Repeaters which are defined for operational speedsup to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specifiedcapabilities include: various PHY types for access networks, PHYs suitable for metropolitan areanetwork applications, and the provision of power over selected twisted pair PHY types.

This project is a revision of IEEE Std 802.3-2002 integrating approved amendments and corrigenda plus corrections and clarifications submitted as maintenance changes through the IEEE 802.3 maintenance process. This project will not add any significant new functionality.
This project is expected to merge at least four amendments into the base standard. It also adds maintenance changes submitted through the IEEE 802.3 maintenance process ( to fix errors and ambiguities in the published standard. This will provide a single base document for ongoing work and satisfy IEEE-SA SB requirements.
