interface_name

The name of the network interface this connection is bound to.

If not set, then the connection can be attached to any interface of the appropriate type (subject to restrictions imposed by other settings).

For software devices this specifies the name of the created device.

For connection types where interface names cannot easily be made persistent (e.g. mobile broadband or USB Ethernet), this property should not be used. Setting this property restricts the interfaces a connection can be used with, and if interface names change or are reordered the connection may be applied to the wrong interface.
