Does changing the MAC address on a single vlan interface work? If I have: eth0 eth0.100 eth0.101 eth0.102 and I change the MAC address on eth0.101 to something different than eth0, will it actually work? I have issued a 'ip link set' command and it appears to have done the right thing, but I'm not yet able to test it, and will need to revise my strategy if it doesn't work. Thanks James
