I've done the same:
root@h4222:~# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.b827ebbd9e51 no eth0
eth0.3
I've set both eth0 and eth0.3 to promiscuous mode (ifconfig ethX[.y] promisc), and neither eth0 or eth0.3 have an IP, but br0 does. I'm not able to communicate with the IP assigned to the bridge from either interface.
Thank you very much for the helpful suggestions, it is greatly appreciated.
