wwn
Displays the World Wide Name (WWN) and serial number of the switch.
Synopsis wwn [-sn ]
Description Use this command to display the WWN associated with a switch and to display the switch serial
number. The switch WWN is a 64-bit number that has eight colon-separated fields each consisting
of one or two hexadecimal digits between 0 and ff. The switch WWN is a factory-set parameter that
cannot be changed by the end user. The WWN is used as the license ID in many cases, but the only
official string to be used for requesting licenses is the licenseidShow output. Alternately, use
switchShow to display the switch WWN.
In addition to the WWN, all switches have a unique 24-bit Fibre Channel address that is used for
communicating with the switch. Use farbricShow to display the FC address in addition to the WWN.
Note The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
