Configuration example

Network requirements
As shown in
Router. Server sends critical data traffic, Telephone sends voice traffic, and Host A and Host B send
non-critical data traffic. On the Router, because the rate of incoming interface GigabitEthernet 1/0/1 is
higher than outgoing interface Serial 2/0/1, congestion may occur on Serial 2/0/1.
The critical traffic from Server and Telephone is transmitted preferentially when congestion occurs in the
network. At the same time, certain bandwidth is guaranteed for traffic from Host A and Host B to reduce
traffic delay. When congestion deteriorates, packets are dropped based on precedence.
Use WFQ in conjunction with WRED for queue scheduling and packet dropping.
