Community Insight

FCNS is the Fibre Channel Name Server. The fcns proxy-port command configures a proxy port for a VSAN, which creates a name-server database entry that lets one name server proxy another. It is not FLOGI database creation nor WWN to VSAN mapping.

The 'fcns proxy-port wwn-id vsan vsan-id' command registers a name server proxy port for the specified VSAN, adding an entry to the FCNS (Fibre Channel Name Server) database so the switch can proxy or advertise that pWWN name-server info.

Picking D (enables registration of parameters for another node) — that describes the capability proxies enable, but the direct result of the command is adding a name server database entry (B). The command itself adds the entry; D describes a function of proxying.

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. This authorization enables WWNs to register specific parameters for another node. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/93x/san_switching/configuration/guide/b-cisco-nexus-9000-nx-os-san-switching-configuration-guide-933/n9000_managing_flogi_name_server_fdmi_and_rscn_databases.html

Expert Analysis

Why the Answer Is Correct

The command fcns proxy-port 21:00:00:b2:c5:71:32:a9 vsan 100 registers a name server proxy for VSAN 100, which adds an entry to the FCNS name server database. Cisco docs list it under "Registering Name Server Proxies" with the purpose "Configures a proxy port for the specified VSAN."

Why the Other Options Are Wrong

A. Creates a FLOGI database — FLOGI is the login database and is not created by this command. C. Maps WWN to VSAN — that is VSAN database or port mapping, not fcns. D. Enables registration of parameters for another node — that is the capability proxies provide, but the immediate result of the command is the name server entry (B).
