Issue Details

I am configuring dual Ethernet Ports (Eth0 and Eth1) on the controller with Eth1 Port (Secondary) for local network and Eth0 Port(Primary) for a gateway. While restarting the Controller often the  Eth0 (Primary) gets disabled automatically. It is identifying Eth1(Secondary) as the Primary port and I need to reconfigure the IP settings again in NI-MAX. How do I avoid configuring this every time in NI-MAX?
