This read-write object specifies the disposition applied to frames destined to the reserved MAC address 01:80:C2:00:00:06 on this CPD profile, another individually addressable entry within the reserved bridge MAC block. An administrator sets this to control handling of any control-protocol traffic addressed to this specific reserved MAC independent of the other addresses in the range. For example, an operator performing a security review of a CPD profile would step through each Mac0xDispType object including this one to confirm no unexpected reserved-address traffic is being passed through unintentionally.
