This command with no parameters displays the current WWN value. This command with a parameter sets the switch's WWN to the new value. WWN names must have eight colon separated fields each consisting of 1 or 2 hexadecimal digits between 0 and off, with no spaces. After the world wide name is changed, the user is prompted to reboot the switch. The name will not take effect until the switch restarts.
