Name Server Proxy
The name server functionality maintains a database containing the attributes for all hosts and storage
devices in each VSAN. Name servers allow a database entry to be modified by a device that originally
registered the information.
The proxy feature is useful when you wish to modify (update or delete) the contents of a database entry
that was previously registered by a different device.

About Registering Name Server Proxies
All name server registration requests come from the same port whose parameter is registered or changed.
If it does not, then the request is rejected.

About Rejecting Duplicate pWWN
You can prevent malicious or accidental log in using another device's pWWN by enabling the
reject-duplicate-pwwn option. If you disable this option, these pWWNs are allowed to log in to the
fabric and replace the first device in the name server database.
