Manually Enabling FlexAttach Virtual pWWN
You can manually assign a WWN to the interface, without generating it through the switch. Several
checks are done by the NPV core to ensure the uniqueness of virtual pWWNs in the switch. When
duplicate virtual pWWNs are configured, the subsequent logins are rejected by the NPV core switch.
Note • Some ports may be in automode, some in manual mode, and the virtual pWWNs need not be
assigned.
• The port must be in a shut state when a virtual pWWN is enabled.
.
To enable virtual pWWN on each interface manually, follow these steps:
Step 1 Click the Virtual PWWN tab.
A list of interfaces is displayed. (Figure 14-4).
