packets, and while some of them are critical for the router operation and should not be dropped, some can be
dropped without impacting the router operation.
Punt policing frees the RP from having to process noncritical traffic. Traffic is placed in queues based on
various criteria, and you can configure the maximum punt rate for each queue which allows you to configure
the system so that packets are less likely to be dropped from queues that contain critical traffic.
Traffic on certain CPU queues could still be dropped, regardless of the configured punt rate, based on
other criteria such as the queue priority, queue size, and traffic punt rate.
