Overview

ISO/IEC/IEEE 8802-1Q:2020/Amd 2:2021 (Amendment 2) is an amendment to ISO/IEC/IEEE 8802-1Q / IEEE 802.1Q that adds a YANG data model for bridged networks. Published as part of the IEEE/ISO collaborative 802.1Q family, this amendment (adopted from IEEE Std 802.1Qcp‑2018) defines a model-driven representation to support configuration and operational status information for a subset of bridging capabilities used in local and metropolitan area networks.

Key topics and requirements

• YANG data model: Provides a standardized schema for representing bridge configuration and operational state in a machine-readable format.
• Configuration and operational status: The amendment focuses on expressing both configuration parameters and runtime/operational information for bridged LAN elements.
• Bridged networks and MAC bridges: Targets elements and features of bridged local area networks, including Virtual Bridged LAN concepts (VLANs) and MAC bridging fundamentals as addressed by IEEE 802.1Q.
• Standards alignment: Implementations are intended to align with the existing IEEE 802.1Q requirements and the ISO/IEC/IEEE 8802 series structure.
• Interoperability enablement: By standardizing the data model, the amendment supports consistent management and monitoring across multi-vendor networks.

Note: The amendment specifies a YANG model for a subset of features; implementers should consult the full text for exact model scope and normative details.

Practical applications

• Network management and orchestration: Use the YANG model to automate bridge configuration and to collect operational telemetry for bridged LANs.
• NMS/NOC integration: Integrate the standard model into network management systems to enable consistent views and control of VLANs and bridges.
• Vendor device support: Network equipment vendors can implement the YANG model to provide standardized, model-driven management interfaces for MAC bridges.
• Service provider and enterprise LANs: Operators managing campus, data center, or metropolitan area networks benefit from reduced manual configuration and improved operational visibility.

Who should use this standard

• Network equipment vendors and firmware developers
• Network management system (NMS) and orchestration platform developers
• Enterprise and service-provider network architects and operators
• Test labs and integrators focused on multi-vendor interoperability
