IEEE 802.1

The IEEE 802.1, Higher Level Interface( HILI) working group deals with issues that affect all IEEE 802 working groups. These include, in particular, general management issues and aspects ofInternetworking, bridging and routing. Furthermore, the 802.1 working groups deal with virtual LANs( VLAN), data center bridging( DCB), tunneling and tagging, and provider networks.
