Three-Level Hierarchical Queueing Policy: Examples

ASR 9000 Ethernet Line Cards
In this example, policy grand-parent is applied to the main Ethernet interface. The grand-parent policy
limits all outbound traffic of the interface up to 500 Mbps. The parent policy has class vlan1 and vlan2,
and traffic in vlan1 or vlan2 is limited to 40 percent of 500 Mbps. The policy child_policy classifies
traffic based on different services and allocates bandwidth for each class accordingly.
