Chapter 14 Configuring N Port Virtualization About NPV Send documentation comments to [email protected] Figure 14-3 shows the internal FLOGI flows between an NPV core switch and an NPV device. Figure 14-3 Internal FLOGI Flows NPV Core Switch fc 5/10 fwwn fc 1/5 pwwn nwwn NPV Device 184572 Table 14-1 identifies the internal FLOGI parameters that appear in Figure 14-3. Table 14-1 Internal FLOGI Parameters Parameter pWWN nWWN fWWN symbolic port name IP address symbolic node name Derived From The fWWN of the NP port. The VSAN-based sWWN of the NPV device. The fWWN of the F port on the NPV core switch. The switch name and NP port interface string. Note If there is no switch name available, then the output will display "switch." For example, switch: fc1/5. The IP address of the NPV device. The NPV switch name. Although fWWN-based zoning is supported for NPV devices, it is not recommended because: • Zoning is not enforced at the NPV device (rather, it is enforced on the NPV core switch). • Multiple devices behind an NPV device log in via the same F port on the core (they use same fWWN and cannot be separated into different zones). • The same device might log in using different fWWNs on the core switch (depending on the NPV link it uses) and may need to be zoned using different fWWNs. Default Port Numbers Port numbers on NPV-enabled switches will vary depending on the switch model. For details about port numbers for NPV-eligible switches, see Chapter 4, "On-Demand Port Activation Licensing."
