Dell Brocade G620 Brocade 8.0.1 Fabric OS Command Reference - Page 1164

wwn 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 restrictions that may be in place. Refer to "Using Fabric OS Commands" and "Command Availability" for details. Operands This command has the following operands: -sn On enterprise-class platforms, this operand displays the chassis factory serial number following the WWN.
