In a switch, there are two WWNs. One is port WWN and the other is node WWN. What are the differences? Also, what is fabric login? Is it the same as DFA?

Port WWN is the FC network ID for the particular switch port. All entities in an FC network have a WWN. Node WWN is the WWN of the node that is connected to a particular port. In other words it is the WWN of the system or storage device/subsystem that is connected to the switch port. I am not familiar with the acronym DFA so I don't know if it is the same or not - but I doubt it.
