I have a system running Ubuntu 22.04, and a Ettus X310 is connected to said
system via two SFP+ cables.
The latest uhd drivers are installed on the system.
The latest XG firmware image has been flashed onto the X310.
The main issue is that I can't seem to interact with the device, despite having
the correct IP configurations set.
I assume it is a network configuration issue of some kind.
A few important notes for context:
- The two SFP+ interfaces show up fine when running ip a\
- I did set the MTU to 9000
- I configured the IP address for both interfaces by manually adding an
ethernet configuration via Ubuntu's network settings
- I am successfully able to ping the device via 192.168.30.2 and via
192.168.40.2
- I am NOT ABLE to interact with the X310. Both, uhd_find_devices and
uhd_usrp_probe mention no device connected.
- The green lights for the links on the back of the SDR light up (aka link is
present)
I don't understand what I am missing to be able to interact with the device.
See the output below.

I would like some information how I can interface with the X310.
I already checked the official documentation, but I don't see what I am
missing/doing wrong.
