    Hi @Daehyeok_Kim

    Thanks for your update on your debug status. Im glad to know that we have ruled out the cable or card issue. For the switch related queries, I am not the subject matter expert. Could you file a separate forum thread on the Ethernet products Forum (https://community.intel.com/t5/Ethernet-Products/bd-p/ethernet-products). They will be able to guide you from there. Appreciate if you can put in the link to the new thread for the benefit of others who face similar issue.

Thanks for your reply.

I figured out what causes the issue. Since the factory/user image on FPGA does not support auto-negotiation, I had to manually disable auto-negotiation on the switch side. Otherwise, it seems to use auto-negotiation by default, and something went wrong.

Thanks for your help!
