The ethernet hardware (MAC) address can be configured on Sun systems. Trouble can result from duplicate MAC addresses in a subnet, so use with caution.
To change the MAC address of ethernet interface hme0 to 11:22:33:dd:ee:ff, use the following command as superuser:
ifconfig hme0 ether 11:22:33:dd:ee:ff
This is a temporary change that will not persist after a reboot. To make this change permanent, the command can be placed in a runtime control script.
If you have multiple ethernet interfaces, see Configure unique MAC addresses on multiple interfaces.
