About 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. The following figure shows an example application
using NPIV.
Figure 1: NPIV Example

Enabling N Port Identifier Virtualization

To enable or disable NPIV on the switch, perform this task:
Before You Begin
You must globally enable NPIV for all VSANs on the 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.
