Three-Level Hierarchical Queueing Policy: Examples

Three-Level Hierarchical Queueing Policy: Examples
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.
