Please refer to the above topology diagram and attached zip containing the configuration file and resultant pcaps.

To run the test

  • After relocating the ports
  • On the All Devices grid
    • select the "Server" device block and click the "Start Device" button
    • select the "Client" device block and click the "Start Device" button
  • Click "Apply" (this will push the newly acquired addresses down to the FW)
  • After the devices reach the "Connected" state go to "All Streamblocks"
    • select both device blocks, right click and select "ARP/ND" -> "Start ARP/ND"
    • after the "All attempted Arps resolved successfully" is logged, start traffic
