2.3.3 Traffic Policing

Traffic policing is the flow-based traffic limit. It takes corresponding actions to deal with
the flow at exceeding speed, such as discarding or lowering the priority.
You can use the following command to configure the traffic policing.

You have to define the corresponding ACL before performing this configuration task.
The purpose of this configuration task is to implement the traffic policing over the data
flow matching the ACL. The traffic beyond the limit will be dealt with in some other way,
such as discarding.
For details about the command, refer to the Command Manual.

2.3.4 Port Traffic Limit

The port traffic limit is the port-based line rate used for limiting the general speed of
packet output on the port.
You can use the following command to configure port traffic limit.
Perform the following configuration in Ethernet port view.
Operation
traffic-limit inbound { user-group { acl-number |
the acl-name } [ rule rule ] | { ip-group { acl-number |
acl-name } [ rule rule ] | link-group { acl-number |
acl-name } [ rule rule ] }* } target-rate [ exceed action ]
undo traffic-limit inbound { user-group { acl-number |
acl-name } [ rule rule ] | { ip-group { acl-number |
acl-name } [ rule rule ] | link-group { acl-number |
acl-name } [ rule rule ] }* }
