N Port Identifier Virtualization
N port identifier virtualization (NPIV) provides a means to assign multiple FC IDs to a single N port.
This feature allows multiple applications on the N port to use different identifiers and allows access
control, zoning, and port security to be implemented at the application level.
example application using NPIV.
You must globally enable NPIV for all VSANs on the MDS switch to allow the NPIV-enabled
applications to use multiple N port identifiers.
All of the N port identifiers are allocated in the same VSAN.
About Interface States
The interface state depends on the administrative configuration of the interface and the dynamic state of
the physical link.
The administrative state refers to the administrative configuration of the interface as described in
The operational state indicates the current operational state of the interface as described in
