Adapting control plane policing parameters dynamically

An apparatus comprising:

• a hardware processor configured to receive control plane packets from an application specific integrated circuit;
• and
• hardware processing logic stored in a non-transitory computer readable medium and configured to cause the hardware processor to:
• determine whether a first factor is at or below a first threshold value,
• determine whether a second factor is at or below a second threshold value,
• increase a control plane policing (CoPP) throughput for control plane traffic for a class of traffic based on one or more parameters when the first factor exceeds the first threshold value and the second factor does not exceed the second threshold value, and
• decrease the CoPP throughput to cause the second factor to be at or below the second threshold value when the first factor changes and the second factor exceeds the second threshold value.

A system comprising:

• an application specific integrated circuit (ASIC) comprising hardware logic stored in a non-transitory computer readable medium and configured to:
• receive a packet from a network location,
• determine that the packet is a control plane packet, and
• forward the packet based on a control plane policing (CoPP) setting;
• and
• a central processing unit (CPU) subsystem comprising hardware processing logic stored in the non-transitory computer readable medium and configured to:
• determine whether a first factor is at or below a first threshold value,
• determine whether a second factor is at or below a second threshold value,
• increase a CoPP throughput for control plane traffic for a class of traffic based on one or more parameters when the first factor exceeds the first threshold value and the second factor does not exceed the second threshold value, and
• decrease the CoPP throughput to cause the second factor to be at or below the second threshold value when the first factor changes and the second factor exceeds the second threshold value.
