1332BNetwork requirements
As shown in 2517HFigure 235:
• Server, Host A, and Host B can access the Internet through Firewall and Router.
• Server, Host A, and GigabitEthernet 0/1 of Firewall are in the same network segment.
• Host B and GigabitEthernet 0/2 of Firewall are in the same network segment.
Perform traffic control for packets received on GigabitEthernet 0/1 of Firewall from Server and Host A,
respectively, as follows:
• Limit the rate of packets from Server to 54 kbps. When the traffic rate is below 54 kbps, the traffic
is forwarded properly. When the traffic rate exceeds 54 kbps, the excess packets are marked with
IP precedence 0 and then forwarded.
• Limit the rate of packets from Host A to 8 kbps. When the traffic rate is below 8 kbps, the traffic is
forwarded properly. When the traffic rate exceeds 8 kbps, the excess packets are dropped.
Traffic control for packets forwarded by GigabitEthernet 0/1 and GigabitEthernet 0/2 of Router is as
follows:
• Limit the receiving rate on GigabitEthernet 0/1 of Router to 500 kbps, and the excess packets are
dropped.
• Limit the sending rate on GigabitEthernet 0/2 of Router to 1000 kbps, and the excess packets are
dropped.
