(The factory default setting is Down). Tip This command is applicable only to interfaces for which no user configuration exists for the administrative state. Configures the default setting for administrative state of an interface as Down. This is the factory default setting.

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. Figure 32-2 shows an example application using NPIV.

Note All of the N port identifiers are allocated in the same VSAN. 32-14 Cisco Nexus 5000 Series Switch CLI Software Configuration Guide OL-16597-01
