Configuring aggregate CAR
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
action.
Configuration procedure
To configure aggregate CAR:
Step
Command
Remarks
1.
Enter system view.

2.
Configure an aggregate
CAR action.

Configuration example
Network requirements
As shown in
Figure 21
, configure an aggregate CAR to rate-limit the traffic of VLAN 10 and VLAN 100
received on Ten-GigabitEthernet 1/1/5 by using these parameters: CIR is 2560 kbps, CBS is 20000
bytes, and the action for red packets is
discard
.
