Configuring NPV Chapter 21 Configuring N Port Virtualization Send documentation comments to [email protected] • You must explicitly configure the WWN of the internal FLOGI in DPVM.If DPVM is configured on the NPV core switch for an end device that is connected to the NPV device, then that end device must be configured to be in the same VSAN. Logins from a device connected to an NPV device will fail if the device is configured to be in a different VSAN. To avoid VSAN mismatches, ensure that the internal FLOGI VSAN matches the port VSAN of the NP port. • The first login from an NP port determines the VSAN of that port. If DPVM is configured for this first login-which is the internal login of the NPV device-then the NPV core switch's VSAN F port is located in that VSAN. Otherwise, the port VSAN remains unchanged. For details about DPVM configuration, see Chapter 28, "Creating Dynamic VSANs." NPV and Port Security 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; in this way, the port on the NPV core switch will allow communications/links. • All 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 Chapter 46, "Configuring Port Security." 21-22 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
