The way we build the portMapping shall be reconsidered to avoid misalignment with real device configuration. Thus we shall consider :
1) Building the portMapping for a device in the same way as we did it at first device connection, handling the parameters that have been added in the portMapping Yang Model.
2) Handling state added in the portMapping when an equipment is connected, disconnected or reconnected
3) At equipment re-connection checks that all elements of the device (interface, connections...) are present in portMapping, that no elements present in portMapping are missing in the device, and generate assocaited LOGs if this was the case....
