Network requirements
As shown in Figure 12:
• Ten-GigabitEthernet 1/0/3 of Device A is connected to Ten-GigabitEthernet 1/0/1 of Device B.
• Server, Host A, and Host B can access the Internet through Device A and Device B.
Perform traffic control on Ten-GigabitEthernet 1/0/1 of Device A for traffic received from Server and
Host A, respectively, to meet the following requirements:
• Limit the rate of traffic from Server to 102400 kbps: Transmit the conforming traffic, mark the excess
traffic with DSCP value 0, and then transmit the traffic.
• Limit the rate of traffic from Host A to 25600 kbps: Transmit the conforming traffic, and drop the
excess traffic.
