Hi Lijuan, The DTS started without error but the nic single core test failed on a "connection timeout - no response from TRex server" when I tried to run it on an intel nic. This happens when DTS uses arm-dell (traffic generator) to send packets to arm-gigabyte (DUT) using the Intel nic {Ethernet Controller XL710 for 40GbE QSFP+} I wonder if you have any clue on this issue?
