[Discuss-gnuradio] Is It Possible to Access Multiple USRP N2x0s in the same subnet?

[Zhongyuan Zhao]

I want to access multiple USRPs from a host for MIMO. Currently, I need change IP address of host (subnet) to be able to access each USRP.

• Configuration for USRP2 device 0:
  • Ethernet interface IPv4 address: 192.168.10.1
  • Ethernet interface subnet mask: 255.255.255.0
  • USRP2 device IPv4 address: 192.168.10.2
• Configuration for USRP2 device 1:
  • Ethernet interface IPv4 address: 192.168.20.1
  • Ethernet interface subnet mask: 255.255.255.0
  • USRP2 device IPv4 address: 192.168.20.2

Is it possible to access multiple USRP without changing host IP?  Say, if I change some of the FPGA code or UHD. Throughput is not that important. Is there any guideline for developing such FPGA code?

Thanks,
