The total of the configured bandwidth budgets for sub-classes cannot exceed the configured
bandwidth budget speed of the parent class.

19.3 Proportional Bandwidth Allocation

Bandwidth management allows you to define how much bandwidth each class gets; however,
the actual bandwidth allotted to each class decreases or increases in proportion to actual
available bandwidth.

19.4 Bandwidth Management Usage Examples

These examples show bandwidth management allotments on a WAN interface that is
configured for 10Mbps.
