IEEE Std 802.1Q-2011的这一修正案规定了协议、程序和管理对象，这些协议、程序和管理对象提供了一对直连有限功能服务VLAN（S-VLAN）组件的发现、配置和控制，以将客户网桥的服务扩展到远程端口，并允许多个服务在常驻站点端口上共存（例如嵌入式网桥）。-为网桥端口提供反射中继服务的发现、配置和控制。-提供边缘继电器（ERs）和其他利用反射继电器服务的设备的发现和协调配置。-提供动态配置文件- 驱动端口配置。

This amendment to IEEE Std 802.1Q-2011 specifies protocols, procedures, and managed objects that - Provide for the discovery, configuration, and control of a pair of direct-attached limited-function Service VLAN (S-VLAN) components to extend the services of a customer bridge to remote ports and enable coexistence of multiple services on station-resident ports (e.g., embedded bridging). - Provide for discovery, configuration, and control of a Reflective Relay Service for a bridge port. - Provide for discovery of, and coordinated configuration of, edge relays (ERs) and other devices that utilize the reflective relay service. - Provide for dynamic profile-driven port configuration.
