This read-write object specifies the disposition applied to IEEE 802.1x port-authentication protocol frames on this port's CPD profile, identified by MAC address 01:80:C2:00:00:03 and Ethertype 0x888E. An administrator sets this to control whether the port participates in, drops, or tunnels 802.1x authentication exchanges. For example, setting this disposition to drop on a port not requiring 802.1x-based network access control prevents unnecessary processing of authentication frames that should not be applicable there.
