Autonomic Networking feature. An unauthenticated, adjacent attacker can exploit this by replaying captured packets to
reset the Autonomic Control Plane (ACP) channel of an affected system in order to reset the ACP channel of an affected
system, causing autonomic nodes of an affected system to reload and stop responding.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
