N310 configuration and access
Description
This tutorial shows how to configure and access the N310 SDR from an experiment server. The N310 is used as a network based USRP which has a 1Gb control interface and a 10Gb data interface. Both interfaces need to be configure properly for control and data streaming. Product information for the N310 is here.
Network configuration
From a COSMOS console, load a baseline sdr image onto an experiment server - for this example srv1-lg1.sb1.cosmos-lab.org is used.
console:~$ omf load -i baseline-uhd-1804.ndz -t srv1-lg1.sb1.cosmos-lab.org console:~$ omf tell -a on -t srv1-lg1.sb1.cosmos-lab.org
After the experiment server is up, ssh into it and list the all interfaces.
$ ifconfig -a eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.113.1.1 netmask 255.255.0.0 broadcast 10.113.255.255 inet6 fe80::3697:f6ff:fe2a:c2e2 prefixlen 64 scopeid 0x20<link> ether 34:97:f6:2a:c2:e2 txqueuelen 1000 (Ethernet) RX packets 947973 bytes 1253989955 (1.2 GB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 712093 bytes 660515688 (660.5 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 20 memory 0xf7e00000-f7e20000 enp1s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 8000 inet 10.115.1.1 netmask 255.255.0.0 broadcast 10.115.255.255 inet6 fe80::f652:14ff:fe83:b930 prefixlen 64 scopeid 0x20<link> ether f4:52:14:83:b9:30 txqueuelen 1000 (Ethernet) RX packets 18775 bytes 2348158 (2.3 MB) RX errors 0 dropped 17339 overruns 0 frame 0 TX packets 637 bytes 267736 (267.7 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 enp3s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::3697:f6ff:fe2a:c2e1 prefixlen 64 scopeid 0x20<link> ether 34:97:f6:2a:c2:e1 txqueuelen 1000 (Ethernet) RX packets 1095 bytes 67703 (67.7 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 571 bytes 177910 (177.9 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
- en01 is the 1Gb control interface.
- enp1s0 is the 10Gb data interface
Configure enp1s0 so it can talk to the N310's data interface.
$ sudo ifconfig enp1s0 10.115.1.1 netmask 255.255.0.0 mtu 8000
Run uhd_find_devices to detect the available N310s

The above output enumerates all the SDRs that were detected. Use the uhd_usrp_probe command with mgmt_addr to list the device properties of this N310. The ip address must match correctly to the corresponding interface.

Trouble shooting
The FPGA bit file will need to be updated if FPGA version mismatch is generated in the output text of the uhd command above. Follow the steps below to update the FPGA image - this will download and install the FPGA image that is matched with the UHD version being used. Complete details on updating the FPGA is found here.
node:~$ sudo uhd_images_downloader node:~$ uhd_image_loader --args "type=n3xx,addr=10.113.2.1,fpga=HG"
After the image loader completes, power-cycle the N310 from the console and detect the N310 again.
console:~$ omf tell -a on -t srv1-lg1.sb1.cosmos-lab.org console:~$ omf tell -a offh -t srv1-lg1.sb1.cosmos-lab.org
