Abstract: A port mode adaptation method includes a network device determining a status of a port on the network device. The method includes the network device setting a mode of the port to an Ethernet interface mode if the status of the port satisfies a first condition. In this way, when the network device identifies the mode of the port on the network device as the FlexE interface mode, and there is no link at the FlexE shim of the port, the network device may determine that a mode used by a port interconnected with the port is not a FlexE interface mode. In this case, the network device may adaptively set the mode of the port to the Ethernet interface mode, to ensure that the port on the network device can use a same mode as another port interconnected with the port.

Abstract: Embodiments of the present application disclose a point-to-multipoint service transmission method and apparatus. The first node is connected to the second node by using a first additional path, and the first additional path and a second path constitute a first protection path. The second node is connected to the first node by using a second additional path, and the second additional path and a first path constitute a second protection path. The method may include: when the first node is in an active state and the second node is in a standby state, receiving, by the first node by using the first protection path if the first path is faulty, service data sent by the root node; and forwarding, by the first node, the service data to the multiple leaf nodes.
