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.
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
