Configuring N Port Virtualization

NPV and Port Security Configuration Guidelines

Port security is enabled on the NPV core switch on a per interface basis. To enable port security on the NPV core switch for devices logging in via NPV, you must adhere to the following requirements:

•The internal FLOGI must be in the port security database so that, the port on the NPV core switch will allow communications and links.

•All of the end device pWWNs must also be in the port security database.

Once these requirements are met, you can enable port security as you would in any other context. For details about enabling port security, see the Cisco MDS 9000 Family NX-OS Security Configuration Guide.

Configuring N Port Virtualization

This section includes the following topics:

•Enabling N Port Identifier Virtualization, page 7-10

•Configuring NPV, page 7-10

•Configuring NPV Traffic Management, page 7-12

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.

Detailed Steps

To enable or disable NPIV on the switch, follow these steps:

	Command	Purpose
Step 1
	switch# config t	Enters configuration mode.
Step 2
	switch(config)# feature npiv	Enables NPIV for all VSANs on the switch.
Step 3
	switch(config)# no feature npiv	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:
