This read-write object sets the Control Protocol Disposition for frames using the specific reserved MAC address 01:80:C2:00:00:03 on this Ethernet traffic port, an address also shared by several named protocols such as LACP Marker, EFM OAM, and 802.1x depending on Ethertype and subtype. An administrator uses this address-level object when finer control below those named dispositions is required. For example, this object lets an operator apply a disposition to any frame using MAC 03 that does not match a more specific named protocol's Ethertype/subtype combination.
