- If a client tries to create configuration for a
- system-controlled interface that is not present in the
- /interfaces-state/interface list, the server MAY reject
- the request, if the implementation does not support
- pre-provisioning of interfaces, or if the name refers to
- an interface that can never exist in the system. A

- configuration, the feature 'pre-provisioning' is
- advertised.
-
- If the device allows arbitrarily named user-controlled
- interfaces, the feature 'arbitrary-names' is advertised.
-
- When a configured user-controlled interface is created by
- the system, it is instantiated with the same name in the

- implementation MUST restrict the allowed values for this
