In this test scenario, we use a system similar to the LANforge CT503-10g.  The DUT is just a looped-back Ethernet cable.  A real-world use of this test in the lab might have the DUT be a router, firewall, switch, or LAN.  A field deployment could have one LANforge system at two different end points of a Wide Area Network.  This feature requires LANforge version 5.4.1 or higher.  |
