About Rejecting Duplicate pWWNs
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, see the Cisco Nexus 5000 Series 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, perform this task:
Step 1 Click FC > Name Server.
You see the Name Server dialog box as shown in Figure 19-3.
