I am designing a FPGA containing a MAC that connects to an external PHY. The FPGA company supplies an example design that can immediately be used to illustrate the operation of the MAC. The development board containing the FPGA is connected to a Windows 7 laptop running Wireshark 2.6 1. When I configure the development board to send a continuous stream of packets Wireshark never captures any data. I have the Local Area Connection Status window open while the data is transmitting and the byte count increments rapidly because it sees data on the cable. The ethernet LED on the laptop is flashing indicating that there is traffic on the cable. I am running Wireshark as an administrator. Are there any suggests to make Wireshark capture this data?
