step 3, after receiving the ethernet data frame, the FPGA analyzes the ethernet data frame to obtain a destination MAC address or a destination Vlan ID of the ethernet data frame, and replaces the destination MAC address or the destination Vlan ID of the ethernet data frame with an MAC address or a Vlan ID corresponding to a third port of the ethernet switching device according to an MAC address conversion relationship or a Vlan ID conversion relationship configured in advance by the FPGA; in order to better ensure the correctness of the Ethernet data frame, the FPGA carries out check sum calculation again on the check bit of the Ethernet data frame which replaces the destination MAC address or the destination Vlan ID; then sending the layer 2 data frame to the receiving end of the second port of the LSW, and going to step 4;
the MAC address conversion relation or Vlan ID conversion relation may be sequentially increased or decreased in order of the MAC address or Vlan ID, or may be a MAC address that is set to be changed into another MAC address when the FPGA is configured, where the two MAC addresses may be randomly set, and there is no rule between the two, or may be set according to a certain rule;

one or more ports to be tested on the ethernet switching device may be provided, and only steps 1 to 2 need to be executed when the port is one; when the number of the ports is more than one, the ethernet data frame needs to traverse each port to be tested according to the above steps.
