My research group recently got an Ettus X410. We are wanting to
connect to it through two MT27800 NICs on our server. We are able to
set up the IP addresses on the server and running uhd_find_devices
shows the USRP having the correct IP address that we are expecting.
When we go to run the benchmark_rate test we get the following error:

Any suggestions on how to fix this?

This looks like a simple networking issue.
First things first--can you "ping" the ip addresses of the device?
If you explicitly use the device address, instead of letting UHD "hunt"
for it, does it still do this?
benchmark_rate --args "addr=<ip address of device> type=x400"
