| IEEE 802.1 Standard | Description |
|---|---|
| 802.1D | Relates to MAC Bridges. It defines the architecture and bridge operation of wired Ethernet. |
| 802.1Q | Defines VLAN tagging and trunking. It allows multiple bridged networks to transparently share the same physical network link without leakage of information between networks. |
| 802.1X | Provides an authentication mechanism to devices wishing to attach to a LAN or WLAN. |
| 802.1AE | Specifies MAC Security (MACsec), providing encryption and integrity protection for data on Ethernet links. |
| 802.1AX | Formerly known as 802.3ad, it defines Link Aggregation Control Protocol (LACP) for bundling several physical ports to form a single logical link. |
| 802.1Qbb | Provides Priority-based Flow Control (PFC) for Ethernet, allowing for lossless Ethernet transport. |
| 802.1Qaz | Defines Enhanced Transmission Selection (ETS), which provides bandwidth management among different traffic types. |
| 802.1Qau | Specifies Congestion Notification (QCN), which aims to mitigate congestion in Ethernet networks. |
| 802.1AC | Refines the definition of VLAN tagging as specified in 802.1Q. |
| 802.1Qca | Path Control and Reservation for Data Traffic, providing a way to manage traffic paths within a network. |
| 802.1Qcj | Provides for Operations, Administration, and Maintenance (OAM) capabilities that are applicable in bridged and virtual bridged networks. |
