-1. As mentioned in the [https://orbit-lab.org/wiki/Hardware/bDomains/cSandboxes/bSB2 sb2.orbit] page, the X310s have their port 1 directly connected to their respective nodes, and the IP addresses hardcoded to 192.168.40.2 as given in the [https://files.ettus.com/manual/page_usrp_x3x0.html#x3x0_setup_network X310 manual]. To access the X310s Run eth_config_sb2_orbit.sh on both the nodes. It sets a static IP address 192.168.40.1 on eno2 interface.
