Overview

ISO/IEC/IEEE 8802-1AB:2017/Amd 1:2023 is an amendment to the ISO/IEC/IEEE 8802-1AB (IEEE 802.1AB) family that adds a YANG data model for station and media access control connectivity discovery. Published as Amendment 1 in 2023 (prepared as IEEE 802.1ABcu-2021), this document provides a standardized modeling layer to represent topology-discovery information and to support configuration and status reporting for bridges and MAC-level components in local and metropolitan area networks.

Keywords: ISO/IEC/IEEE 8802-1AB, YANG data model, connectivity discovery, topology discovery, IEEE 802.1AB, LLDP, network management

Key Topics

• YANG data model for connectivity discovery
  • Introduces a machine-readable YANG model to represent connectivity-discovery state and configuration.
• Unified Modeling Language (UML) information model
  • Supplies an information model that maps discovery concepts to the YANG representation (UML-based description as part of the amendment).
• Configuration and status reporting
  • Enables standardized access to configuration parameters and operational state for bridges and bridge components that participate in topology/ connectivity discovery.
• Standards adoption and provenance
  • Prepared within the IEEE 802.1 working group (802.1ABcu) and adopted through the ISO/IEC fast-track process; copyright and publishing handled by IEEE.

Applications

This amendment is practical for organizations and professionals who need standardized, interoperable models for network topology data and network management:

• Network equipment vendors
  • Implement the YANG model in switches, bridges and NIC firmware to expose discovery state and configuration via NETCONF/RESTCONF.
• Network operators and service providers
  • Use consistent data models to automate topology inventory, verification, and troubleshooting across multi-vendor environments.
• Network management and orchestration developers
  • Integrate discovery data into NMS, SDN controllers, and orchestration tools to enable inventory reconciliation, fault isolation and automated provisioning.
• System integrators and test labs
  • Validate interoperability of connectivity-discovery features and ensure consistent management-plane behavior.

Related Standards

• IEEE 802.1AB (station and media access control connectivity discovery / LLDP) - base standard for topology discovery.
• YANG modeling concepts (network management models) - the amendment supplies a YANG module to align 802.1AB discovery with model-driven management workflows.

This amendment improves interoperability by providing a vendor-neutral, standard YANG representation of station and MAC connectivity discovery, making topology and link-state data easier to consume, automate, and integrate into modern network management systems.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of ISO/IEC documents should be noted. This document was drafted in accordance
with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).
IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating
Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its
standards through a consensus development process, approved by the American National Standards
Institute, which brings together volunteers representing varied viewpoints and interests to achieve the
final product. Volunteers are not necessarily members of the Institute and serve without compensation.
While the IEEE administers the process and establishes rules to promote fairness in the consensus
development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the
information contained in its standards.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details
of any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents) or the IEC list of patent
declarations received (see https://patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT),
see www.iso.org/iso/foreword.html. In the IEC, see www.iec.ch/understanding-standards.
ISO/IEC/IEEE 8802-1AB:2017/Amd.1 was prepared by the LAN/MAN of the IEEE Computer Society (as
IEEE 802.1ABcu-2021) and drafted in accordance with its editorial rules. It was adopted, under the “fast-
track procedure” defined in the Partner Standards Development Organization cooperation agreement
between ISO and IEEE, by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems.
A list of all parts in the ISO/IEC/IEEE 8802 series can be found on the ISO and IEC websites.
Any feedback or questions on this document should be directed to the user’s national standards body. A
