Configuring aggregate CAR
Aggregate CAR overview
An aggregate 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 aggregate CAR
