Firewall Policers

More Information:

    Firewall Policers

    You use policers to apply limits to traffic flow and set consequences for packets that exceed these limits usually applying a higher loss priority so that if packets encounter downstream congestion, they can be discarded first. Policers apply only to unicast packets.
