Description
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

If this command is frequently configured on the classes of the same policy, the last
configuration will overwrite the previous ones.
