The Firewall maintains a facility to control packet storms. Storms are packet bombardments that exceed the high threshold
value configured for an interface. During a storm, packets are throttled until the rate falls below the configured rate,
severely impacting performance for the interface. Thresholds are configured in terms of packets per second.
