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).

This corrigendum to IEEE Std 802.1AC?-2016 corrects the value of the LLC Encapsulation EtherType.(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)

This amendment to IEEE Std 802.1Q-2018 as amended by IEEE 802.1Qcp-2018 provides a YANG data model in support of configuration and operational status information for a subset of Bridging capabilities.

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.

This amendment defines enhancements to fronthaul profiles in order to address new developments in fronthaul interface standards, and related synchronization and syntonization standards. This amendment also addresses errors and omissions in existing content.

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

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

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.
