UMLR — Ports

We have a debate about the concept of Port in the SysML RTF and I would like to get your opinion about some points because we have divergent interpretations of the UML specification.

Since a port can be typed by a class, what about the properties and the owned behavior(s) defined for that class?

Does the interaction point that instantiates the port has slots to hold runtime values of the properties defined by its type or does it only refer to values held by the instance of its owner (or by a instance of its environment)?

How ownedbehaviors defined by the type of the port may impact the way interactions at that port are managed?
