A YANG data model that supports configuration, status reporting, and monitoring for Connectivity Fault Management (CFM) for Two-Port MAC Relays, Customer VLAN Bridges, and Provider Bridges is further developed by this amendment to IEEE Std 802.1Q™-2018. See also IEEE Std 802.1Qcp™-2018 for the introduction of this YANG data model.

This amendment specifies a Unified Modeling Language (UML)-based information model and a YANG data model that allows configuration and status reporting for bridges and bridge components for Connectivity Fault Management (CFM) as specified by this standard with the capabilities currently specified in clause 12.14 (CFM entities) of this standard. It further defines the relationship between the information and data model and models for the other management capabilities specified in this standard. Additionally, this amendment will address open CFM maintenance items.

Bridges, as specified by this standard, allow the compatible interconnection of information technology equipment attached to separate individual LANs.
