3. World Wide Name (WWN)
When the Virtual Fabric feature is enabled on a switch, each logical switch has a unique
switch WWN. Use the wwn command to display the switch WWN.
If you cannot use the wwn command because the switch is inoperable, you can get the
primary WWN from the same place as the serial number, except for the Brocade DCX/DCX-4S
and DCX 8510-8/DCX 8510-4. For the Brocade DCX/DCX-4S and DCX 8510-8/DCX 8510-4
access the numbers on the WWN cards by removing the Brocade logo plate at the top of the
non-port side. The WWN is printed on the LED side of both cards.
