NPV Mode

A switch is in NPV mode after a user has enabled NPV and the switch has successfully rebooted. NPV
mode applies to an entire switch. All end devices connected to a switch that is in NPV mode must log in
as an N port to use this feature (loop-attached devices are not supported). All links from the edge
switches (in NPV mode) to the NPV core switches are established as NP ports (not E ports), which are
used for typical interswitch links. NPIV is used by the switches in NPV mode to log in to multiple end
devices that share a link to the NPV core switch.
In-order data delivery is not required in NPV mode because the exchange between two end devices
Note
always takes the same uplink to the core from the NPV device. For traffic beyond the NPV device, core
switches will enforce in-order delivery if needed and/or configured.
After entering NPV mode, only the following commands are available:
aaa

banner
