Dear community,

I follow this guide
https://kb.ettus.com/USRP_N300/N310/N320/N321_Getting_Started_Guide  and
now I 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 encap:Ethernet  HWaddr d4:5d:64:9c:d1:86
          inet addr:192.168.20.1  Bcast:192.168.20.255  Mask:255.255.255.0
          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
