QoS Configuration Example

Configuration Example of Traffic Policing

Network requirement
As shown in Figure 1-9, an enterprise network connects all the departments through a device. PC1, with
the IP address 192.168.0.1 belongs to the R&D department and is connected to GigabitEthernet 1/0/1
of the switch. The marketing department is connected to GigabitEthernet 1/0/2 of the switch.
Configure traffic policing to satisfy the following requirements:
z Set the maximum rate of outbound IP packets sourced from the marketing department to 64 kbps.
Drop the packets exceeding the rate limit.
z Set the maximum rate of outbound IP packets sourced from the R&D department to 128 kbps. Drop
the packets exceeding the rate limit.
