Aggregation CAR Configuration

Aggregation CAR Overview

With aggregation CAR, one CAR is used to rate limit flows on different ports as a whole. If aggregation
CAR is enabled for multiple ports, the total traffic on these ports must conform to the traffic policing
parameters set in the aggregation CAR.
The S7900E series switches implement aggregation CAR with QoS policies.
Only the SD and EB cards support QoS policies that contain aggregation CAR actions.

Referencing an Aggregation CAR in a Traffic Behavior

Configuration prerequisites
You have determined the parameters in the aggregation CAR.
