Abstract: The application provides a network device, which includes: a main control board and a service board, where the main control board includes a processor and a switching chip, and the service board includes a physical layer component. The switching chip is connected to the physical layer component by using a system bus. The system bus consists of a SerDes link, and is configured to transmit service data and control information of a port of the physical layer component. The processor controls the port of the physical layer component by using the control information of the port of the physical layer component. The network device transmits the service data and the control information by using the system bus, so that the service board does not need to set a CPU processing the control information, thereby expanding an interface flexibly, and reducing device complexity and hardware costs.
