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.

Registering Name Server Proxies

To register the name server proxy, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# fcns proxy-port
21:00:00:e0:8b:00:26:d0 vsan 2

Rejecting Duplicate pWWN

To prevent malicious or accidental log in using another device's pWWN, enable the
reject-duplicate-pwwn option. If you disable this option, such pWWNs are allowed to log in to the
fabric and replace the first device in the name server database.
To reject duplicate pWWNs, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# fcns reject-duplicate-pwwn vsan 1
switch(config)# no fcns reject-duplicate-pwwn
vsan 1

Displaying 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.
Use the show fcns command to display the name server database and statistical information for a
specified VSAN or for all VSANs (see Examples

About the Name Server Proxy Feature
Purpose
Enters configuration mode.
Configures a proxy port for the specified
VSAN.
Purpose
Enters configuration mode.
Logs out devices when they log into the
fabric if the pWWNs already exist.
Overwrites the first device's entry in the
name server database with the new device
having the same pwwn (default).
