CAR
CAR provides the means to limit the input or output transmission rate on an interface or
subinterface based on traffic sources and destinations, while specifying policies for handling
traffic that exceeds bandwidth allocations. Rate policies can be set based on IP access lists, IP
Precedence, Media Access Control (MAC) addresses, or a QoS group. The difference between
CAR and traffic shaping is that CAR is a policing scheme. CAR sets maximum limits on traffic
