IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
802.3ak: 2004: 10GBASE-CX4 10 Gbit/s Ethernet over twinaxial cabling: 802.3-2005: 2005: A revision of base standard incorporating 802.3ae, 802.3ak and errata 802.3an: 2006: 10GBASE-T 10 Gbit/s Ethernet over copper twisted pair cable 802.3ap: 2007: Backplane Ethernet, 1 and 10 Gbit/s over printed circuit boards (10GBASE-KR and 10GBASE-KX4) 802 ...
802.3ak-2004 (54) CX4/SFF-8470/IEC 61076-3-113 Designed to support short distances over copper cabling, it uses InfiniBand 4x connectors and CX4 twinaxial cabling and allows a cable length of up to 15 m. Was specified in IEEE 802.3ak-2004 which has been incorporated into IEEE 802.3-2008.
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards.
The IEEE 802.3cm standard was approved on January 30, 2020. The IEEE 802.3cu standard was approved on February 11, 2021. The IEEE 802.3ck and 802.3db standards were approved on September 21, 2022. In November 2022 the IEEE 802.3df project objectives were split in two, with 1.6T and 200G/lane work being moved to the new IEEE 802.3dj project
The 802.3 maintenance task force report for the 9th revision project in November 2006 noted that certain 802.1 layers (such as 802.1X security) were positioned in the protocol stack below link aggregation which was defined as an 802.3 sublayer. [6]
It is used with IEEE 802.3, IEEE 802.4, IEEE 802.5, IEEE 802.11 and other IEEE 802 physical network layers, as well as with non-IEEE 802 physical network layers such as FDDI that use 802.2 LLC. The SNAP and LSAP fields are added to the packets at the transmitting node in order to allow the receiving node to pass each received frame to an ...
Green Ethernet technology was a superset of the 802.3az standard. In addition to the link load power savings of Energy-Efficient Ethernet, Green Ethernet works in one of two ways. First, it detects link status, allowing each port on the switch to power down into a standby mode when a connected device, such as a computer, is not active.
