Abstract: A link negotiation system includes a second device that determines a link configuration policy based on a status of a receiver of an interface of the second device, where the link configuration policy indicates an association relationship between a unidirectional logical lane and a unidirectional physical lane in a high-speed serial link between a first device and the second device, the unidirectional logical lane is a logical lane from the first device to the second device in the high-speed serial link, and the unidirectional physical lane is a physical lane from the first device to the second device in the high-speed serial link; and sends the link configuration policy to the first device.
