Traffic policing and GTS configuration example

Network requirements

As shown in Figure 11:

• The server, Host A, and Host B can access the Internet through Router A and Router B.

• The server, Host A, and GigabitEthernet 2/1/0 of Router A are in the same network segment.

• Host B and GigabitEthernet 2/1/1 of Router A are in the same network segment.

Perform traffic control for the packets GigabitEthernet 2/1/0 of Router A receives from the server and

Host A, as follows:

• Limit the rate of packets from the server to 54 kbps. When the traffic rate is below 54 kbps, the

traffic is forwarded. 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. When the traffic rate exceeds 8 kbps, the excess packets are dropped.

Perform traffic control on GigabitEthernet 2/1/0 and GigabitEthernet 2/1/1 of Router B, as follows:

• Limit the incoming traffic rate on GigabitEthernet 2/1/0 to 500 kbps, and the excess packets are

dropped.

• Limit the outgoing traffic rate on GigabitEthernet 2/1/1 to 1000 kbps, and the excess packets are

dropped.

Configuration procedure

1. Configure Router A:

# Configure GTS on GigabitEthernet 2/1/2, shaping the packets when the sending rate exceeds

500 kbps to decrease the packet loss rate of GigabitEthernet 2/1/0 of Router B.
