Aggregation CAR configuration
Aggregation CAR overview
An aggregation CAR action is created globally and can be directly applied to interfaces or referenced
in the traffic behaviors associated with different traffic classes to police multiple traffic flows as a whole.
The total rate of the traffic flows must conform to the traffic policing specifications set in the aggregation
CAR action.

NOTE:
In a traffic behavior, do not configure an aggregation CAR action together with any priority marking
action (including local precedence, drop precedence, 802.1p priority, DSCP value, and IP precedence
marking actions). Otherwise, you will fail to apply the QoS policy properly.
