Enabling NPV

When you enable NPV, the system configuration is erased and the switch reboots.
We recommend that you save your current configuration either in boot flash memory or to a TFTP server
Note
before you enable NPV.
To enable NPV, perform this task:
Command
Step 1
switch# configure terminal
switch(config)#
Step 2
switch(config)# npv enable
Step 3
switch(config-npv)# no npv enable
switch(config)#

NPV uses a load-balancing algorithm to automatically assign end devices in a VSAN to one of the
NP uplinks (in the same VSAN) upon initial login. If there are multiple NP uplinks in the same
VSAN, you cannot assign an end device to a specific NP uplink.
If a server interface goes down and then returns to service, the interface is not guaranteed to be
assigned to the same NP uplink.
The server interface is only operational when its assigned NP uplink is operational.
Both servers and targets can be connected to the switch when in NPV mode.
Fibre Channel switching is not performed in the edge switch; all traffic is switched in the core
switch.
NPV supports NPIV-capable servers. This capability is called nested NPIV.
Connecting two Cisco NPV switches together is not supported.
Only F, NP, and SD ports are supported in NPV mode.
