If you manually install two flows to connect the ports, does the ping work? For example: dpctl add-flow tcp:<your TP-LINK> in_port=3,actions=output:4 dpctl add-flow tcp:<your TP-LINK> in_port=4,actions=output:3 That would troubleshoot the two test hosts' ports and configurations, and the connections to the TP-LINK. If that works, I'd suggest running tshark on both hosts to see what packets they're receiving. It looks as though traffic is only flowing in one direction, based on the flows above.
