Description

Amendment Standard – Superseded. This standard defines an architecture for Virtual Bridged LANs, the services provided in Virtual Bridged LANs, and the protocols and algorithms involved in the provision of those services. (Incorporates IEEE Std 802.1Q-1998, IEEE Std 802.1u™-2001, IEEE Std 802.1v™-2001, and IEEE Std 802.1s™-2002)
