What Is the Difference Between Interface-based CAR and Global CAR?
Interface-based CAR limits the rate of packets on an interface. Global CAR limits the rate of packets on all interfaces of a specified LPU if the slot ID is specified, and limits the rate of packets on all interfaces of each LPU if the slot ID is not specified.
Assume that the CAR is 5000 kbit/s. If the CAR is applied to an interface, the maximum rate for the interface to receive and send packets is 5000 kbit/s. If the CAR is applied globally and the slot ID is not specified, the sum of the maximum rates of all the interfaces is 5000 kbit/s.
