I'm in a corporate environment with a DHCP server with static assignments for my server. I have one physical nic with several sub-interfaces. I statically assign different MAC addresses for each sub-interface to get another IP address from the DHCP server. For some reason, my server is not taking the static MAC addresses. You'll notice that ifconfig shows each interface with the same MAC.
How do I assign unique MAC addresses to my sub-interfaces?
$ cat interfaces
auto lo
iface lo inet loopback
auto eth0:1
iface eth0:1 inet dhcp
hwaddress ether 00:0c:29:31:24:fa
hostname gwrt-test
client gwrt-test
auto eth0:2
iface eth0:2 inet dhcp
hwaddress ether 00:0c:29:31:25:fa
hostname gwrt-test2
client gwrt-test2
$ ifconfig
