You can view Fibre Channel switch ports and their associated WWNs using either the switch's graphical interface or CLI commands, which display port status, speed, and connected device information.
Most Fibre Channel switches provide a graphical or table view of ports:
For Cisco MDS or Nexus switches, you can use show commands to retrieve port and WWN information:
show interface fcX/Y – Displays operational state, speed, and optical module details.show flogi database – Lists logged-in Fibre Channel devices with WWPN (World Wide Port Name) and WWNN (World Wide Node Name) .show zone or show vsan – Displays zoning information and ports associated with each VSAN.show fabric binding – Shows registered WWPNs and their associated FCIDs .show device-alias – Displays device aliases mapped to WWNs for easier identification .xx:xx:xx:xx:xx:xx:xx:xx).By combining graphical views and CLI commands, administrators can efficiently monitor, manage, and troubleshoot Fibre Channel switch ports and their WWNs, ensuring proper connectivity and fabric integrity.
