Hi Pat - I recently verified that the N321 QAFP+ interface works with UHD 4.0 release. I am also using an Intel XL710 (QDA2, but that probably doesn’t matter too much). The trick for me was using the Intel QSFP+ NIC configuration tool to set the NIC to 2x(2x10 Gb) mode. This is the setting that the N321 requires, and one that the NIC provides. Once that was set then you need to configures the host and USRP network interfaces as you normally would. After all of that, the link worked very nicely! I hope this is useful! - MLD
