Abstract

The embodiment of the invention provides a network device and a physical layer address allocation method. The network device comprises a CPU, a CPLD and a plurality of expansion card slot positions; the CPLD monitors whether expansion cards are inserted in the expansion card slot positions, a first indicating position corresponding to the first expansion card slot position with an inserted expansion card in a register of the CPLD is set as an identifier used for indicating that the expansion card has been inserted; the CPU determines the identifier of the first expansion card slot position, determines a first PHY address corresponding to the identifier of the first expansion card slot position according to a pre-stored corresponding relation between the identifier of the first expansion card slot position and the PHY address, and sets a second indicating position corresponding to the first expansion card slot position in the CPLD as the first PHY address; and the CPLD obtains the firstPHY address from the register and allocates the first PHY address to a PHY chip contained in the expansion card inserted in the first expansion card slot position.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for allocating network equipment and physical layer addresses. Background technique [0002] In order to improve the port density and the flexibility of port type configuration, network devices often provide external expansion card slots, and the expansion card slots provide external ports, thereby realizing on-demand configuration of port types. Such as figure 1 As shown, the network device includes a mainboard 100 and an expansion card slot 200. The mainboard 100 is provided with a Switch (exchange) chip 110, and an expansion card can be inserted in the expansion card slot 200. The expansion card includes a PHY (Physical Lay, physical layer) chip 210. Here, the expansion card containing the PHY chip 210 can provide one or more ports externally; the Switch chip 110 manages the PHY chip 210 through the MIIM (Medium Independent Interface Management, Media Independ...
