Hey Cy, it's getting a bit late here in Germany¹, I'll try to come up with a test setup tomorrow; haven't tried that feature (it being rather fresh). Excellent debugging by the way; my first reaction was that, hm, if MAC address resolution fails, the device might be trying to inadvisably stre

Hi Marcus, I appreciate you quick responses.  They have been useful. If you look at the code in xport_adapter_ctrl.cpp, specifically xport_adapter_ctrl::add_remote_ep_route(),  you will notice that the dest_udp is required.I don't think we are getting to the "catch" part, since based on all the

Actually until I looked at the diagram I did not know that. The 2974 is a product designed by the traditional NI R&D team, and I’ve never had one in my hands. But yeah I agree it should work like any other X310. Sent from my iPhone > On May 17, 2023, at 12:27 PM, cjohn...@serranosystems.com

Hi Marcus, On an external host. As you know, the sfp1 interface is not connected to the internal switch (going to the i7, only sfp0). But we are not using the i7. Instead, we are using sfp1, connected to a different host, which should work similar to an X310 (with external host). Thanks,
