Full title and description

IEEE Standard for Local and metropolitan area networks—Bridges and Bridged Networks—Amendment 30: YANG Data Model (IEEE Std 802.1Qcp-2018). This amendment specifies a UML-based information model and a YANG data model to support configuration, status reporting and operational information for a defined subset of bridging capabilities in IEEE Std 802.1Q.

Abstract

A YANG data model in support of configuration and operational status information for a subset of Bridging capabilities is provided. The amendment defines YANG modules (including ieee802-dot1q-bridge and ieee802-dot1q-vlan-bridge) and the mapping between the information model and YANG modules to enable programmatic configuration and monitoring of MAC Bridges, Two‑Port MAC Relays (TPMRs), Customer VLAN Bridges and Provider Bridges. Security considerations for configurable objects are included.

Scope

This amendment provides a YANG data model and supporting information model to allow configuration and operational status reporting for a defined subset of bridging features specified in IEEE Std 802.1Q. It covers modeling and management interfaces for bridges and bridge components (MAC Bridges, TPMRs, Customer VLAN Bridges, Provider Bridges) corresponding to specific clauses of the base standard and defines how the YANG modules relate to other management models such as IEEE Std 802.1AX and IEEE Std 802.1X.

Key topics and requirements

• UML-based information model defining the management objects and relationships for bridging capabilities.
• YANG modules (e.g., ieee802-dot1q-bridge, ieee802-dot1q-vlan-bridge) for configuration and operational state.
• Support for configuration and state reporting of MAC Bridges, Two‑Port MAC Relays (TPMRs), Customer VLAN Bridges and Provider Bridges.
• Mapping of YANG data nodes to clauses of IEEE Std 802.1Q (targeted clause coverage is specified in the amendment).
• Security considerations for configurable objects that could affect forwarding or control-plane state (e.g., priority, VLAN filtering databases).

Typical use and users

Intended users include network equipment vendors (switch/router developers), network management system (NMS) and orchestration developers, implementers of device YANG models, and network operators who require programmatic configuration and monitoring of bridging functions in enterprise and carrier networks. The amendment is used where YANG‑based management of bridge behavior is required or when integrating bridge management into automation/orchestration systems.

FAQ

Q: What is this standard?

A: IEEE Std 802.1Qcp-2018 is Amendment 30 to IEEE Std 802.1Q-2018 titled "YANG Data Model" — an amendment that defines a UML information model and corresponding YANG modules for a subset of bridging capabilities. Published 14 September 2018.

Q: What does it cover?

A: It provides YANG modules and an information model to support programmatic configuration and operational status reporting for selected bridge and bridge‑component features (e.g., MAC Bridges, TPMRs, VLAN bridge aspects) and specifies the mapping to the base IEEE 802.1Q clauses. Security considerations for configurable objects are included.

Q: Who typically uses it?

A: Switch and network device vendors, YANG model implementers, NMS/orchestration software developers, and network operators who need automated management of bridging functions.

Q: Is it current or superseded?

A: The amendment was published in 2018. Its content has been maintained as part of the 802.1Q revision/roll‑up work and is included in subsequent consolidated editions (see IEEE Std 802.1Q-2022 roll‑up of 2018 plus amendments). For the canonical, up‑to‑date rules for implementation and to determine whether pieces have been superseded or integrated, consult the consolidated 802.1Q revision documents.

Q: Is it part of a series?

A: Yes — it is one amendment in the 802.1Q amendment series addressing bridges and bridged networks; other related amendments provide YANG models or functional extensions (for example 802.1Qcx, 802.1Qcw, 802.1Qcr, etc.), and the series is periodically rolled up into consolidated editions such as IEEE Std 802.1Q-2022.

Q: What are the key keywords?

A: YANG, YANG data model, UML, IEEE 802.1Q, bridges, VLAN, MAC Bridge, TPMR, network management, configuration, operational state.
