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:
Set the maximum rate of outbound IP packets sourced from the marketing department to 64 kbps.
Drop the packets exceeding the rate limit.
Set the maximum rate of outbound IP packets sourced from the R&D department to 128 kbps. Drop
the packets exceeding the rate limit.

Configuration procedure
1) Define an ACL for traffic classification.
# Create ACL 2000 and enter basic ACL view to classify packets sourced from the 192.168.1.0/24
network segment.
<Sysname> system-view
[Sysname] acl number 2000
[Sysname-acl-basic-2000] rule permit source 192.168.1.0 0.0.0.255
[Sysname-acl-basic-2000] quit
# Create ACL 2001 and enter basic ACL view to classify packets sourced from the 192.168.2.0/24
network segment.
