Abstract
A port status synchronization method, related device, and system, where a physical layer (PHY) device or an external processor connected to the PHY device determines whether a first service interface of the PHY device changes, and when the first service interface changes, controls a second service interface of the PHY device to restart auto-negotiation and sends, using the second service interface, an auto-negotiation advertisement packet to a first device connected to the second service interface in order to trigger the first device to synchronize, according to the auto-negotiation advertisement packet, a status of the second service interface and a status of the first service interface such that performing port status negotiation and synchronization between a link layer (media access control (MAC)) device or the first device and the PHY device using a service interface is achieved, without a need of disposing a management data input/output (MDIO) interface.
