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
