Problems solved by technology

In one of the devices for realizing the connection of this kind of MDIO interface, the PHY equipment and the MAC equipment are respectively arranged on different physical boards, and the number of the PHY equipment and the MAC equipment arranged on each physical board is large, so it needs to be installed on the back The same number of MDIO interfaces as the number of PHY devices or MAC devices is set on the board to realize the connection between the MDIO interfaces of the PHY devices and MAC devices, which consumes a lot of hardware resources and wastes the space for wiring on the backplane
[0004] Another connection realization method of the existing management data interface is to set a system equipment management module independent of the external processor, so that there are many information transmission paths, the signal connection is complicated and cumbersome, and the communication nodes are increased, thereby increasing the signal processing. Delay, reducing the reliability of link layer and physical layer communication

Abstract

The present application discloses a port state synchronization method, related equipment and system. It is judged by the PHY equipment or an external processor connected to the PHY equipment whether the first service interface of the PHY equipment changes. The service interface restarts self-negotiation, and sends a self-negotiation announcement message to the first device connected to the second service interface through the second service interface, so as to trigger the first device to synchronize the second service interface and the first service interface according to the self-negotiation announcement message. The status of the interface realizes the purpose of port status negotiation and synchronization between the MAC device or the first device and the PHY device through the service interface, and does not need to be equipped with a management MDIO interface to connect the PHY device and the MAC device, simplifying the design of the circuit interface; no need to equip additional The management module or the management channel connects the PHY device and the MAC device, reduces information interaction nodes, and enhances the reliability of management information transmission.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a port state synchronization method, related equipment and a system. Background technique [0002] When the communication equipment in the existing Ethernet is in the application state, the link layer (Media Access Control, MAC) device and the physical layer (PHYSICAL, PHY) are generally implemented through the Management Data Input / Output (MDIO) interface. ) Transfer of port status information and control management information between devices, and transfer of service information through the service (Ethernet, Eth) interface between the MAC device and the PHY device. Wherein, the PHY device includes a system-side port and a line-side port, specifically connecting the system-side port to the MAC device to implement a service interface between the MAC device and the PHY device; and, connecting to the peer device through the line-side port of the PHY device, In order...
