    2020==== Prepare network setup for USRP access ====
    21 Each X310 on SB2 is connected to its respective node through a 10G interface adapter installed in Port 0 of the USRP. In this configuration, the X310 will have a default IP address of 192.168.40.2 (see [http://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_setup_network_host_interface X310 User Manual]). To setup network connectivity, make sure eth2 is configured with an address in the 192.168.40.0/24 subnet .
