IEEE 802.1D is the
Ethernet
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1 ...
MAC bridges standard which includes
bridging,
Spanning Tree Protocol and others. It is standardized by the
IEEE 802.1 working group. It includes details specific to linking many of the other 802 projects including the widely deployed
802.3
IEEE 802.3 is a working group and a collection 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 Institute of Electrical and Electronics Eng ...

802.11
IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of media access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer com ...
(Wireless LAN) and
802.16 (WiMax) standards.
Bridges using
virtual LANs (VLANs) have never been part of 802.1D, but were instead specified in separate standard,
802.1Q
IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying pro ...
originally published in 1998.
By 2014, all the functionality defined by IEEE 802.1D has been incorporated into either
IEEE 802.1Q-2014 (Bridges and Bridged Networks) or IEEE 802.1AC (MAC Service Definition). 802.1D is expected to be officially withdrawn in 2022
