About Rejecting Duplicate pWWN You can prevent malicious or accidental log in using another device's pWWN. These pWWNs are allowed to log in to the fabric and replace the first device in the name server database. Rejecting Duplicate pWWNs To reject duplicate pWWNs, refer to the Cisco MDS 9000 Family CLI Configuration Guide About Name Server Database Entries The name server stores name entries for all hosts in the FCNS database. The name server permits an Nx port to register attributes during a PLOGI (to the name server) to obtain attributes of other hosts. These attributes are deregistered when the Nx port logs out either explicitly or implicitly. In a multiswitch fabric configuration, the name server instances running on each switch shares information in a distributed database. One instance of the name server process runs on each switch. Viewing Name Server Database Entries To view the name server database using Device Manager, follow these steps: Step 1 Click FC > Name Server. You see the Name Server dialog box as shown in Figure 34-3. OL-17256-03, Cisco MDS NX-OS Release 4.x Cisco MDS 9000 Family Fabric Manager Configuration Guide 34-3
