Enabling the Device to Dynamically Adjust the Rate at Which It Processes Packets from NAC Users

When a lot of NAC users send authentication or log off requests to the device, the CPU usage may be overloaded especially when the CPU or memory usage is already high (for example, above 80%). After the device is enabled to dynamically adjust the rate of packets from NAC users, the device limits the number of NAC packets received per second if the CPU or memory usage is high. This function reduces loads on the device CPU.
