When you enter the feature npv command on a storage-capable switch from Cisco, what is the result?

NPV mode cannot be activated without a switch reload; the fundamental change in switch role from a full FC switch to an edge proxy device requires a reboot and configuration erase.

This choice likely describes enabling N-Port ID Virtualization (NPIV) or contains a description that inaccurately represents the reload and erase behavior specific to the NPV feature.

Entering 'feature npv' on a Cisco MDS or NPV-capable switch triggers an automatic reload and erases the running configuration before NPV mode is activated. This is mandatory because enabling NPV converts the switch from a full Fibre Channel switch with its own domain ID into an edge device that proxies N-Port logins to an upstream core switch, requiring a completely clean configuration state to function correctly.

N-Port ID Virtualization (NPIV) is a distinct feature from NPV that allows a single physical port to present multiple virtual N-Ports and does not require a switch reload or configuration erase to enable.
