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.

802.1t: 1d Maintenance
802.1u: 1q Maintenance
802.1v: VLAN Classification by Protocol and Port: The group is working on the classification of virtual LANs by port and protocol.

802.1x: Port Based Network Access Control. This standard defines client-server based access control and authentication and prevents unauthorized clients from connecting to a network through publicly accessible ports. 802 .1x works with the Temporal Key Integrity Protocol (TKIP) or the Counter Mode with CBC-MAC Protocol (CCMP) and plays a decisive role in WLAN security according to 802.11i

802.1AQ: Shortest Path Bridging (SPB).
802.1AR: Secure Device Identity. It deals with the discovery of end devices.
802.1AS: Generalized Precision Time Protocol (gPTP).Timing and synchronization of time-critical applications in the home.

802.1BA:Audio Video Bridging (AVB) Systems. The standard describes the profiles of an AVB system.
802.1BR: Bridge PortExtension.
802.1CB:FrameReplication and Elimination of Redundancy. Mechanisms by which a receiver extracts information from redundant messages, e.g. using the first message and deleting the following redundant messages.
802.1CM:Time-Sensitive Networking (TSN) for the access nodes (fronthaul)
802.1Qa: Forwarding and Queuing for Time-Sensitive Streams.
802.1Qat:Stream Reservation Protocol (SRP). Defines the reservation and allocation of transmission resources (bandwidths) for critical data streams in the network. It also provides for the identification of media streams.
802.1Qau:Quantized Congestion Notification (QCN).
802.1Qav: Forwarding and Queuing Enhancements for Time-Sensitive Streams. It describes the assurance of quality of service via queuing and forwarding rules and supports the simultaneous transmission of isochronous and asynchronous data traffic.
