-* Upon logging into the nodes, run eth_config.sh script to setup the 10G data interfaces on the nodes, DATA1, DATA2. After running the script, you should see that the data interfaces have the appropriate IP addresses assigned, as per this [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1#IPAddressAssignment table].The nodes should then be able to access the USRP N310s sdr1-s1-lg1 and sdr1-md1 which can be checked by running uhd_find_devices.
+* Upon logging into the nodes, run eth_config.sh script on both the nodes. This sets up the 10G data interfaces DATA1, DATA2. After running the script, you should see that the data interfaces have the appropriate IP addresses assigned, as per this [https://wiki.cosmos-lab.org/wiki/Architecture/Domains/cosmos_sb1#IPAddressAssignment table].
