Discovering the Name of the First Network Interface

Tufin Orchestration Suite is managed on the first network interface, which is automatically assigned by the operating system based on the PCI ID. Any changes made to the network and DNS settings need to be made on this interface. If you do not know the name of the first network interface, you are going to need to discover it first.

For TufinOS 3.50 or above you can modify the first network interface using the tools provided by TOS. See details in Configuring Network and DNS Settings.
