This read-write object sets the Control Protocol Disposition for the IEEE 802.3ad Marker protocol, identified by MAC address 01:80:C2:00:00:03, Ethertype 0x8809, and subtype 02, on this Ethernet traffic port. An administrator configures this to control whether link-aggregation marker frames used to verify frame distribution across a customer's LAG are passed through or discarded at the demarcation. For example, setting this disposition to pass-through lets a customer verify their own link aggregation group's frame distribution across a link that traverses this device.
