Although I’m only testing with 1 right now, I have 2 X310s connected,
each with two SFP+. IPs of one radio is 192.168.40.2/30.2 and the
other radio is 192.168.130.1/140.1.
I do have another non-10Gb card connected to a separate device with a
192 subnet.
Ifconfig for the 192.x devices is:
inet 192.168.130.99 netmask 255.255.255.0 broadcast 192.168.130.255
inet 192.168.140.98 netmask 255.255.255.0 broadcast 192.168.140.255
inet 192.168.30.99 netmask 255.255.255.0 broadcast 192.168.30.255
inet 192.168.40.99 netmask 255.255.255.0 broadcast 192.168.40.255
inet 192.168.122.1 netmask 255.255.255.0 broadcast 192.168.122.255
The NICs are direct connected to the radios via the SFP+ so don’t
think the IP stack could be sending the data to the X310s any other
way (or is there something else I should check?). The args we pass
into uhd::usrp::multi_usrp::make are:
addr=192.168.30.2, second_addr=192.168.40.2,send_frame_size=9000
*Might be useful to do a ping -s 8500 to the X310, and see if it works.
