bandwidth filter. You can configure up to one bandwidth filter per bandwidth class. You can
also configure bandwidth classes without bandwidth filters. However, it is recommended that
you configure child-classes with filters for any classes that you configure without filters. The
Prestige leaves the bandwidth budget allocated and unused for a class that does not have a
filter itself or child-classes with filters. View your configured bandwidth classes and child-
classes in the Class Setup screen (see
The total of the configured bandwidth budgets for child-classes cannot exceed the configured
bandwidth budget speed of the parent class.

16.3 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.

16.4 Bandwidth Management Usage Examples

These examples show bandwidth management allotments on a WAN interface that is
configured for 640Kbps.

16.4.1 Application-based Bandwidth Management Example

The bandwidth classes in the following example are based solely on application. Each
bandwidth class (VoIP, Web, FTP, E-mail and Video) is allotted 128kbps.

16.4.2 Subnet-based Bandwidth Management Example

The following example uses bandwidth classes based solely on LAN subnets. Each bandwidth
class (Subnet A and Subnet B) is allotted 320kbps.
