This standard specifies the operation of Bridge Port Extenders, including management, protocols, and algorithms. Bridge Port Extenders operate in support of the MAC Service by Extended Bridges.

An optional local medium access control (MAC) address space structure, known as the Structured Local Address Plan (SLAP), is provided in this amendment to IEEE Std 802?-2014 in order to allow multiple administrations to coexist. This structure designates a range of local MAC addresses for protocols using a Company ID (CID) assigned by the IEEE Registration Authority. Another range of local MAC addresses is designated for assignment by administrators. The amendment recommends a range of local MAC addresses for use by IEEE 802? protocols.(The PDF of this standard is available at no cost to you compliments of the IEEE GET program http://ieeexplore.ieee.org/servlet/opac?punumber=8016707.

A Secure Device Identifier (DevID) is cryptographically bound to a device and supports authentication of the device?s identity. An Initial Device Identifier (IDevID) provide by the supplier of a device can be supplemented by Local Device Identifiers (LDevIDs) facilitating enrollment (provisioning of authentication and authorization credentials) by local network administrators.

Explicit path control, bandwidth reservation, and redundancy (protection, restoration) for data flows are specified in this amendment to IEEE Std 802.1Q-2014.

A protocol and a set of managed objects that can be used for discovering the physical topology from adjacent stations in IEEE 802? LANs are defined in this document

Enhancements to the forwarding process that supports scheduled traffic is provided in this amendment to IEEE Std 802.1Q-2014.

Protocols, procedures, and managed objects for the transport of timing over local area networks are defined in this standard. It includes the transport of synchronized time, the selection of the timing source (i.e., best master), and the indication of the occurrence and magnitude of timing impairments (i.e., phase and frequency discontinuities).

YANG data model that supports configuration, status reporting, and monitoring for Connectivity Fault Management (CFM) for Two-Port MAC Relays, Customer VLAN Bridges, and Provider Bridges is further developed by this amendment to IEEE Std 802.1Q?-2018. See also IEEE Std 802.1Qcp?-2018 for the introduction of this YANG data model.

How all or part of a network can be secured transparently to peer protocol entities that use the MAC Service provided by IEEE 802? LANs to communicate is specified in this standard. MAC security (MACsec) provides connectionless user data confidentiality, frame data integrity, and data origin authenticity.(The PDF of this standard is available at no cost to you compliments of the IEEE GET program https://ieeexplore.ieee.org/browse/standards/get-program/page)

Port-based network access control allows a network administrator to restrict the use of IEEE 802(R) LAN service access points (ports) to secure communication between authenticated and authorized devices. This standard specifies a common architecture, functional elements, and protocols that support mutual authentication between the clients of ports attached to the same LAN and that secure communication between the ports, including the media access method independent protocols that are used to discover and establish the security associations used by IEEE 802.1AE(TM) MAC Security.

Procedures and managed objects for Bridges and end stations to perform Asynchronous Traffic Shaping over full-duplex links with constant bit data rates are specified in this amendment to IEEE Std 802.1Q(TM)-2018.

Enhancements to fronthaul profiles are defined in this amendment to IEEE Std 802.1CM-2018 in order to address new developments in fronthaul interface standards and in related synchronization and syntonization standards.

Correction of technical and editorial errors identified by the IEEE 802.1 maintenance activity are presented in this document.

Protocols, procedures, and managed objects for a Link-local Registration Protocol (LRP) to replicate a registration database from one end to the other of a point-to-point link and to replicate changes to parts of that database are specified in this standard. A facility is provided to purge the replicated database if the source becomes unresponsive. LRP is optimized for databases on the order of 1 Mbyte.

How all or part of a network can be secured transparently to peer protocol entities that use the MAC Service provided by IEEE 802? LANs to communicate is specified in this standard. MAC security (MACsec) provides connectionless user data confidentiality, frame data integrity, and data origin authenticity.

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.
