--- features: - | Adds a ``physical_network`` field to the port object in REST API version 1.34. This field specifies the name of the physical network to which the port is connected, and is empty by default. This field may be set by the operator to allow the Bare Metal service to incorporate physical network information when attaching virtual interfaces (VIFs). The REST API endpoints related to ports provide support for the ``physical_network`` field. The `ironic developer documentation `_ provides information on how to configure and use physical networks. upgrade: - | Adds a ``physical_network`` field to the port object in REST API version 1.34.
