    Abstract: A loop avoidance method, device and system. The system includes a first network device and a second network device in an internal network, a first Ethernet port and a second Ethernet port of the two network devices are of a first type, and loop avoidance priorities of the Ethernet ports are different from each other; root media access control (MAC) addresses of the two network devices are the same, and are different from respective network bridge MAC addresses; the second network device receives a loop detection frame from the first Ethernet port through the second Ethernet port, where a source address of the loop detection frame is the root MAC address, and blocks the second Ethernet port according to the loop avoidance priority. A network device blocks, according to a loop avoidance priority, an Ethernet port connected to an external network to avoid changing a topology of an internal network.

    Abstract translation: 循环回避方法，设备和系统。 该系统包括内部网络中的第一网络设备和第二网络设备，两个网络设备的第一以太网端口和第二以太网端口是第一类型，并且以太网端口的回路优先级彼此不同 ; 两个网络设备的根媒体访问控制（MAC）地址相同，与各自的网桥MAC地址不同; 第二网络设备通过第二以太网端口从第一以太网端口接收环路检测帧，其中环路检测帧的源地址是根MAC地址，并且根据回路优先级阻塞第二以太网端口。 网络设备根据环路回避优先级阻塞连接到外部网络的以太网端口，以避免改变内部网络的拓扑。
