Hi,

This interface is used ONLY when the ‘ip nat enable’ is enabled. This interface can be found with the command ‘show ip interface brief’ or ‘show interfaces’  but you can't configure this interface. NAT Virtual Interface; NVI removes the requirements to configure an interface as either NAT inside or NAT outside.
