Configuration Example of Traffic Policing
Network requirement
An enterprise network connects all the departments through an 4210 Ethernet switch. The R&D
department belongs to the network segment 192.168.1.0/24 and connects to the switch through
Ethernet 1/0/1; the marketing department belongs to the network segment 192.168.2.0/24 and
connects to the switch through Ethernet 1/0/2.
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.
