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 encap:Ethernet  HWaddr d4:5d:64:9c:d1:86             inet addr:  Bcast:  Mask:           inet6 addr: fe80::3ac5:ee40:457b:3554/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:9000  Metric:1           RX packets:1311 errors:0 dropped:0 overruns:0 frame:0           TX packets:1937 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:191173 (191.1 KB)  TX bytes:249297 (249.2 KB) How can I use 10 Gb SFP port1? Any 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?
