If enabled, blacklist clients exceeding the Gratuitous ARP attack rate. If active, and logging is enabled for the corresponding session rule, this feature logs every packet. Shows if the controller will log received ICMP errors. You can configure user role policies that prevent Layer-3 traffic between users or networks but this does not block Layer-2 traffic. If enabled this setting prevents the forwarding of Layer-2 traffic between wired or wireless users. If this value exceeds the maximum configured rate, the controller will register a denial of service attack sessions. If enabled, the controller monitors the number of TCP sessions requests per second. If this value exceeds the maximum configured rate, the controller will register a denial of service attack. If enabled, the controller monitors the number of TCP SYN messages per second. If enabled, the controller monitors the number of ICMP pings per second.

This option should be disabled when you have mobile clients on the network as enabling this option will cause mobility to fail.
If enabled, this feature prevents data from passing between two clients until the three-way TCP handshake has been performed.
