Control Plane Flood Protection

•
Enable Control Plane Food Protection – Select this option to have the firewall forward only control traffic destined for the firewall to the system Control Plane core (Core 0) if traffic on the Control Plane exceeds the threshold specified in Control Flood Protection Threshold (CPU %). This option is not enabled by default.

To give precedence to legitimate control traffic, excess data traffic is dropped. This restriction prevents too much data traffic from reaching the Control Plane core, which can cause slow system response and potential network connection drops. The percentage configured for control traffic is guaranteed.

•
Control Flood Protection Threshold (CPU %) – Enter the flood protection threshold as a percentage. The minimum is 5 (%), the maximum is 95, and the default is 75.
