Update: I have another cable: https://www.mouser.com/ProductDetail/Amphenol-FCI/10110818-2005LF/?qs=sGAEpiMZZMsvnOgGvSjZeOwTQadc946rbBouJzzeCxE%3D With this cable, The USRP X300 - PC link *works as expected*. With my Intel XDACBL3M cable, the link *doesn't work*.
When connecting the 10110818-2005LF cable between 2 ports in my NIC interface and setting up a local network (between enp1s0f1 and enp1s0f2), I can ping in both directions. When connecting the Intel XDACBL3M cable between 2 ports in my NIC interface and setting up a local network (between enp1s0f1 and enp1s0f2), I can ping in both directions. Conclusion: the cable works, but not when connecting to a USRP. Is there any reason that the Intel XDACBL3M cable won't work specifically with the USRP X300 ports? Can anybody confirm that they tested a USRP X with an Intel XDACBL3M cable (or another one from the same series)?
