wwn
Displays the world wide name (WWN) and factory serial number of the switch or chassis.
SYNOPSIS
wwn [-sn]
DESCRIPTION
Use this command to display the WWN associated with a switch or chassis and to display the factory
serial number. The 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 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 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 fabricShow to display the FC address in addition to the WWN.
NOTES
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.

-sn
On enterprise-class platforms, this operand displays the chassis factory serial
