Using the car command, you can configure traffic monitoring for a class. Using the
undo car command, you can delete the configuration of traffic monitoring.
When being used in interface policy, car can be used in the input or output direction
of the interface.
Applying a policy configured with car on an interface will cause the previous qos car
command ineffective.
If this command is frequently configured on the classes of the same policy, the last
configuration will overwrite the previous ones.
