I have 4 SFI/SFP+ NICs, shown below (Intel 82599ES), although right now I only have two of them connected to anything (the X310 in question)
0b:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) 0b:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) 0d:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) 0d:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01) 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 Thanks, Ryan From: USRP-users <[email protected]> On Behalf Of Marcus D.

After building and installing 3.15.0 on my system and flashing the X310, everything seemed okay. However, we now get this error when starting up: [WARNING] [X300] You requested a send frame size of (9000) but your NIC's max frame size is (8000).Please verify your NIC's MTU setting using 'ip link' or set the send_frame_size argument appropriately.UHD will use the auto-detected max frame size for this connection. And when we start to transmit, odd errors like this show up (what is 'this can cause 27.0464' trying to tell me?): [WARNING] [MULTI_USRP] The total sum of rates (66.666667 MSps on 1 channels) exceeds the maximum capacity of the connection (overflows (O) MSps). This can cause 27.0464. I'm using 10Gb NICs that again, worked fine with 3.11. The MTUs are set to 9000 (I've also tried 9001, 9100, nothing seems to change the warning). ip link 6: enp13s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether f8:f2:1e:42:e1:d4 brd ff:ff:ff:ff:ff:ff 7: enp13s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether f8:f2:1e:42:e1:d5 brd ff:ff:ff:ff:ff:ff The usrp_probe output is below.
