Configuring N Port Virtualization

Enabling N Port Identifier Virtualization

You must globally enable NPIV for all VSANs on the MDS switch to allow the NPIV-enabled applications
to use multiple N port identifiers.
Note All of the N port identifiers are allocated in the same VSAN.
To enable or disable NPIV on the switch, perform these steps:
Step 1 switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# feature npiv
Enables NPIV for all VSANs on the switch.
switch(config)# no feature npiv
(Optional) Disables (default) NPIV on the switch.

Configuring NPV

When you enable NPV, the system configuration is erased and the system reboots with the NPV mode enabled.
Note
We recommend that you save the current configuration either on bootflash or a TFTP server before NPV (if
the configuration is required for later use). Use the following commands to save either your non-NPV or NPV
configuration:
switch# copy running bootflash:filename
The configuration can be reapplied later using the following command:
switch# copy bootflash:filename running-config
Note
NPV cannot be enabled or disabled from the ASCII configuration file. You can enable or disable only from
the command line.
To configure NPV using the CLI, perform the following steps:
