In this example, we show how to configure hierarchical QoS. As shown in the following
figure, two customers, EVC-A and EVC-B, paid for both uplink and downlink bandwidth
of 5 Mbps and 8 Mbps, respectively. EVC-A requires assurance of 1 Mbps for its voice
traffic and 2 Mbps for its privacy data traffic. EVC-B also requires assurance of 1.5 Mbps
for its voice traffic and 2.5 Mbps for its privacy data traffic. Next, we will illustrate how to
reach the purpose of bandwidth profiling for EVC-A and EVC-B.
