FC NPV Guidelines and Limitations
• You can configure zoning for end devices that are connected to edge switches using all the available
member types on the core switch. However, the preferred way of zoning servers connected to any switch
in NPV mode is via PWWN, device-alias and fcalias. You must place multiple servers in the same zone
only when using smart zoning. For more information about smart zoning on Cisco MDS switches, refer
the chapter Configuring and Managing Zones in Cisco MDS 9000 Series Fabric Configuration Guide
.
• Port tracking is not supported in FC NPV mode.
• Port security is supported on the core switch for devices logged in through the FC NPV switch. Port
security is enabled on the core switch on a per-interface basis. To enable port security on the core switch
for devices that log in through an FC NPV switch, you must adhere to the following requirements:
• Edge switches can connect to multiple core switches. In other words, different NP ports can be connected
to different core switches.
• 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 FC NPV mode.
• Fibre Channel switching is not performed in the edge switch; all traffic is switched in the core switch.
• FC NPV supports NPIV-capable servers. This capability is called nested NPIV.
• Connecting two Cisco FC NPV switches together is not supported.
• Only F and NP ports are supported in FC NPV mode.
• The BB_SCN is not supported.
• The auto-speed is not supported.
• The default port speed is 16000.
• 8G speed is not supported for server and target interfaces.
• IDLE is the fill pattern used for 8G NP links. All NPIV core switches need to have fill-pattern IDLE
configured. IDLE is configured on Cisco Nexus switches and Cisco MDS switches using switchport
fill-pattern command.
• The speed must be configured manually for each port (based on the speed of peer).
• 64 B2B credits are assigned to each FC interface; this is not configurable.
• When a san-port channel is created, it is created in channel mode active by default; channel mode on
is not supported for NPV switch.
• FC NPV (upto 16G) is supported on N9K-C93180YC-FX, beginning with Cisco NX-OS Release
7.0(3)I7(2).

◦ The internal FLOGI must be in the port security database; in this way, the port on the core switch
will allow communications and links.
◦ All the end device pWWNs must also be in the port security database.
