I just call P’ Winyou for consult about our solution, He suggests this is the best for our needs in order to control the MAC address, and we can customize for additional requirements.
This solution we apply with physical LAN level not VLAN, So impact in future with new trend technology possible is VM Workstation and DVI and configure bridging on user environments.
On that time we can extend allow maximum mac address to 2 or 3 to support again.
