Clarification on SAN solution

Just want a quick clarification on your answer title SAN solution dated 27, April 2001.

You mentioned the HBA/subsystem need to implement a NL port to support switch environment.

I thought NL port is strictly for arbitrated loop topology only. I believe a NL port can only connect to another NL port or FL port. I thought you'll need a N port to support switch/fabric topology. Please clarify.

I can't remember the context from the previous question, but both N and NL ports can exist in a fabric and connect to switches. The only ports in a public loop that can connect to a switch are NL ports - they connect through the FL port in the switch. (There can only be one FL port per loop.) NL ports in loops can connect to either L or NL ports in the same loop.
