Information About FCoE NPV
• FCoE NPV implements FIP snooping as an extension to the NPV function while retaining the
traffic-engineering, vsan-management, administration and trouble-shooting aspects of NPV.
• FCoE NPV and NPV together allow communication through FC and FCoE ports at the same time. This
provides a smooth transition when moving from FC to FCoE topologies.
You can enable FCoE NPV by choosing one of the following methods:
• Enable FCoE and then enable NPV—This method requires that you enable FCoE first using the
feature fcoe command and then you enable NPV by using the feature npv command. When FCoE is
enabled, the default mode of operation is FC switching and when you enable NPV, the mode changes
to NPV mode. Switching to NPV mode automatically performs a write erase and reloads the system.
After the reload, the system comes up in NPV mode. To exit NPV mode and return to FC switching
mode, enter the no feature npv command. Exiting NPV mode also triggers a write erase and a switch
reload. This method requires the Storage Protocols Services Package (FC_FEATURES_PKG) license
.
• Enable FCoE NPV—When you enable FCoE NPV using the feature fcoe-npv command, the mode
changes to NPV. When you use this method, a write erase and reload does not occur. This method
requires a separate license package (FCOE_NPV_PKG). This license is also included in the Storage
Protocol Services License.

Interoperability with FCoE-Capable Switches
The Cisco Nexus device interoperates with the following FCoE-capable switches:
• Cisco MDS 9000 Series Multilayer switches enabled to perform FCF functions (EthNPV and VE)
• Cisco Nexus 7000 Series switches enabled to perform FCF functions (EthNPV and VE)
• Cisco Nexus 4000 Series switches enabled for FIP Snooping
For detailed information about switch interoperability, see the
Matrix.
