The MAC Move Protection is a Layer 2 mechanism that enables the system to detect MAC address movements across different network ports.

This enhancement specifically applies to VPLS, allowing detection of MAC moves across various attachment circuits (AC), attachment circuits (PW), and Mesh P in any combination. This improvement enhances network stability and security by mitigating unintended MAC movements.

For more details, refer to the MAC Move Protection section in the OcNOS Multi-Protocol Label Switching Guide, Release 6.6.0.
