Configuration example for HQoS through nesting
QoS policies
Network requirements
A company has agencies in site X and site Y, respectively. The agency in site X has three departments,
A, B, and C. The agency in site Y has one department D. Site X and site Y are connected through a
service provider WAN. Site X is connected to the WAN through a 50-Mbps Ethernet port.
Department A is on network segment 192.168.0.0/24, department B is on network segment
192.168.1.0/24, and department C is on network segment 192.168.2.0/24. Departments A and B are
important departments, and need the IP voice communication with department D. The voice packets are
UDP packets with destination port number 2000. Additionally, bandwidth must be guaranteed for the
data traffic from departments A and B to department D. The communication between department C and
department D is unimportant, and carries only data traffic.
Configure HQoS through nesting QoS policies to:
• Guarantee 15 Mbps of bandwidth and limit the bandwidth to 15 Mbps for the traffic from
department A to department D, and guarantee 25 Mbps of bandwidth and limit the bandwidth to
25 Mbps for the traffic from department B to department D.
• Guarantee 1.5 Mbps of bandwidth for the voice traffic from department A to department D, and 2.5
Mbps of bandwidth for the voice traffic from department B to department D. Send voice traffic with
the highest priority.

Configuration procedures
# Configure IP addresses for interfaces. (Details not shown)
# Create three ACLs to match packets sourced from IP segment 192.168.0.0/24 (department A), packets
sourced from IP segment 192.168.1.0/24 (department B), and packets with destination UDP port number
2000.
