Figure 12 Line rate implementation
The token bucket mechanism limits traffic rate when accommodating bursts. It allows bursty traffic to
be transmitted if enough tokens are available. If tokens are scarce, packets cannot be transmitted
until efficient tokens are generated in the token bucket. It restricts the traffic rate to the rate for
generating tokens.
Line rate can only limit traffic rate on a physical interface, and traffic policing can limit the rate of a
flow on an interface. To limit the rate of all the packets on interfaces, using line rate is easier.

Configuring traffic policing

Configuration restrictions and guidelines

In a traffic behavior, do not configure traffic policing with any priority marking action (including local
precedence, 802.1p priority, and DSCP precedence marking actions) in the same traffic behavior.
Otherwise, you will fail to apply the QoS policy successfully.

Configuration procedure

To configure traffic policing:
Step
1. Enter system view.
2. Create a class and enter
class view.
3. Configure match criteria.
4. Return to system view.
5. Create a behavior and enter
behavior view.
6. Configure a traffic policing
action.
7. Return to system view.
