# Configure line rate on interface GigabitEthernet 2/1/3, set the maximum available bandwidth and
the maximum reserved bandwidth for interface GigabitEthernet 2/1/3, and apply the parent QoS
policy to the outgoing packets of interface GigabitEthernet 2/1/3.

Configuration example for reserving and sharing
bandwidth through interface-level hierarchical CAR
Network requirements
A company has two agencies in site X and site Y. The agency in site X has two departments, A and B.
The agency in site Y has one department, C. Site X and site Y are connected through a service provider
WAN. Site X and site Y connect to the WAN through a 50-Mbps Ethernet link provided by the service
provider.
Department A is on network segment 192.168.0.0/24, and department B is on network segment
192.168.1.0/24. Each of department A and department B sends to department C three types of traffic,
voice, video, and data, whose IP precedence values are 7, 6, and 0, respectively. Each of the two
departments must reserve certain bandwidth for the voice, video, and data services, and share the idle
bandwidth when any service does not transmit traffic.
Configure interface-level hierarchical CAR to:
• Reserve 3 Mbps of bandwidth for the voice traffic of department A and 4 Mbps of bandwidth for
the voice traffic of department B.
• Reserve 7 Mbps of bandwidth for the video traffic of department A and 8 Mbps of bandwidth for
the video traffic of department B.
• Reserve 5 Mbps of bandwidth for the data traffic of department A and 8 Mbps of bandwidth for the
data traffic of department B.
• Share the remaining 15 Mbps of bandwidth among these services. When a service does not
transmit traffic, the other service can preempt the idle bandwidth.
