I am building a setup for performing a bandwidth test on custom cabling that carries two gigabit Ethernet channels. I have a working setup that includes two computers and two network switches to which the custom Ethernet cabling connects (see wiring diagram).
While not apparent in the wiring diagram, the network switches are included in the setup so that the fixture can accommodate several cabling configurations. Each cabling configuration includes two Ethernet channels (ETH0 and ETH1) and both channels are tested simultaneously. Only one cabling configuration is tested at a time - therefore four ETH0 and four ETH1 ports are used during a test.
Is there any way to make this setup work with one network switch? The aim is to configure the switch so that traffic between Computers 1 and 2 travels on the custom cabling under test. I must prevent traffic from simply travelling between the switch ports to which the Computer Ethernet interfaces connect (as this would bypass the custom cabling under test).
