使用通用媒体访问控制（MAC）规范和管理信息库（MIB），为从1 Mb / s到400 Gb / s的选定操作速度指定了以太网局域网操作。 带冲突检测的载波侦听多路访问（CSMA / CD）MAC协议指定了共享介质（半双工）操作以及全双工操作。 速度特定的媒体独立接口（MII）允许使用选定的物理层设备（PHY）通过同轴电缆，双绞线或光缆或电背板进行操作。 多段共享访问网络的系统注意事项描述了中继器的使用，这些中继器的定义是运行速度高达1000 Mb / s。 所有速度均支持局域网（LAN）操作。 其他指定的功能包括：接入网的各种PHY类型，适用于城域网应用的PHY，以及通过选定的双绞线PHY类型提供电源。
Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 400 Gb/s using a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted pair or fiber optic cables, or electrical backplanes. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include: various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted pair PHY types.
