IEEE 802.1

IEEE 802.1 is a working group of the IEEE 802 project of the IEEE Standards Association.

It is concerned with: LAN/MAN bridging and management. Covers management and the lower sub-layers of OSI Layer 2,
 * 802 LAN/MAN architecture
 * internetworking among 802 LANs, MANs and wide area networks
 * 802 Link Security
 * 802 overall network management
 * protocol layers above the MAC and LLC layers
