Configure traffic

Required 

By default, traffic policing is 
disabled. 

Clear the traffic 
policing statistics 

reset traffic-limit inbound acl-rule 

Optional 

 

As the priority of traffic classification rules is higher than that of the default rules used for processing 

protocol packets, configuring traffic policing for all the packets or packets of a VLAN may affect device 

management that is implemented through Telnet and so on.  

 

z 

GigabitEthernet 1/0/1 belongs to VLAN 2 and is connected to the 10.1.1.0/24 network segment 

z 

Perform traffic policing on the packets from the 10.1.1.0/24 network segment, setting the rate to 

128 kbps 

z 

Mark the DSCP precedence as 56 for the inbound packets exceeding the rate limit.
