Configuration example for implementing

hierarchical CAR through nesting QoS policies

Network requirements

A university has three dormitory buildings, A, B, and C. Each dormitory building provides 200

dormitories, and each dormitory is assigned a VLAN ID (1 to 200). The dormitories of a building are

uplinked through the access switch for the building. The access switch of a building performs QinQ for

the packets from users, and tags the packets with a VLAN ID assigned to the building, which is 1 for

building A, 2 for building B, and 3 for building C. The QinQ packets are sent to subinterfaces

GigabitEthernet 2/0/0.1, GigabitEthernet 2/0/0.2, and GigabitEthernet 2/0/0.3 of the router. The

router performs QinQ termination for the packets, and accesses the Internet through a 300-Mbps

Ethernet interface.

Buildings A, B, and C are on network segments 192.168.0.0/24, 192.168.1.0/24, and 192.168.2.0/24,

respectively. Because the bandwidth of the WAN is limited, you need to rate-limit the users: limit the rate

of accessing the external network for each building, and limit the rate of accessing non-HTTP services.

Configure hierarchical CAR through nesting QoS policies to:

• Limit the rate of accessing the external network to 100 Mbps for each building.

• Limit the rate of accessing the non-HTTP services to 30 Mbps for each building.
