Congestion Management —Classified packets are prioritized and placed into queues based on Class of
Service (CoS) markings to ensure preferential treatment to high priority traffic. See “Congestion Manage-
ment” on page 25-10 .

Congestion Avoidance —Weighted Random Early Detection (WRED) is used for admission control
and bandwidth management. Packets that are not high priority are randomly dropped to help avoid “tail
drop” on the queues. See
“Congestion Avoidance” on page 25-20 .

Traffic Policing and Shaping —Packet flows are policed or shaped to limit the rate of traffic received
or sent by the switch. See “Traffic Policing and Shaping” on page 25-22 .
