Control Plane Flood Protection

To configure control plane flood protection:

1. Navigate to Device > Firewall Settings > Advanced.

2. Scroll to Control Plan Flood Protection.

   

3. To have the firewall forward only control traffic destined to the firewall to the system Control Plane core (Core 0) if traffic on the Control Plane exceeds the specified threshold, select Enable Control Plane Food Protection, and then specify the threshold in now available 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.

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

4. Click Accept.
