IEEE 802.1Q-2018

This standard specifies Bridges that interconnect individual LANs, each supporting the IEEE 802 MAC Service using a different or identical media access control method, to provide Bridged Networks and VLANs.

Bridges, as specified by this standard, allow the compatible interconnection of information technology equipment attached to separate individual LANs.

Revision Standard - Superseded. This standard specifies how the Media Access Control (MAC) Service is supported by Bridged Networks, the principles of operation of those networks, and the operation of MAC Bridges and VLAN Bridges, including management, protocols, and algorithms.
