Name Server Proxy
Name Server Proxy
The name server functionality maintains a database that contains 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 need to modify (update or delete) the contents of a database entry that
was previously registered by a different device.
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.
This authorization enables WWNs to register specific parameters for another node.

Procedure
Step 1
Step 2
Rejecting Duplicate pWWNs
By FC standard, NX-OS will accept a login on any interface of a pwwn that is already logged in on the same
switch, same vsan, same fcdomain. To prevent the same pwwn from logging in the same switch on a different
interface, use the port security feature.
By default, any future flogi (with duplicate pwwn) on different switch in the same vsan, will be rejected and
earlier FLOGI retained, which does not follow FC standards.
