You can try to manage the device using DFM and see if the Interfaces are discovered by looking in DFM > Device management > device details > View > and see if the interfaces are being disocvered and are in a managed state or True.
If they are, use Notification Services to create a group for the device for events like operationally down and unresponsive to add a monitor to these Interfaces.
