The BB_SCN of internal FLOGIs on NP ports is always set to zero. The BB_SCN is supported at the

F-port of the NPV device.

Although fWWN-based zoning is supported for NPV devices, it is not recommended because:
• Zoning is not enforced at the NPV device (rather, it is enforced on the NPV core switch).
Multiple devices behind an NPV device log in via the same F port on the core (they use same fWWN
•
and cannot be separated into different zones).
• The same device might log in using different fWWNs on the core switch (depending on the NPV
link it uses) and may need to be zoned using different fWWNs.
