Explanation

The FLOGI database on a Cisco MDS switch records the WWNN and WWPN of every device that has performed a Fabric Login, making it the correct source for retrieving an HBA's world wide node name by port.

Common mistakes.

A. 'show wwn status' displays the WWN block allocated to the MDS switch itself, not the WWNs of externally connected host bus adapters.
B. 'show interface fc 1/20' displays interface counters, link state, speed, and physical statistics but does not report the WWNN of the attached device.
D. 'show fcs database' queries the Fabric Configuration Server for inter-switch fabric topology information, not per-port HBA WWNs.

Concept tested. Cisco MDS FLOGI database HBA WWNN retrieval by port
