can connect to N310 by RJ45 port. And I also can connect to SFP port0. However,
when I try to use SFP port1, it does not work. I found that the green LED
above SFP port 1 does not even illuminate after connecting the PC to it. The
network interface configuration of PC is shown as follows enp1s0 Link

advice would be appreciated. Regards, Heng My guess is that you have a problem
with your cabling, or the SFP+ module that you plugged in to the USRP. What
SFP+ module are you using? What type of wiring/optical?
