16.2 Bandwidth Classes and Filters
Use bandwidth classes and child-classes to allocate specific amounts of bandwidth capacity
(bandwidth budgets). Configure a bandwidth filter to define a bandwidth class (or child-class)
based on a specific application and/or subnet. Use the Class Setup screen (see
on page
168) to set up a bandwidth class's name, bandwidth allotment, and 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 Application-based Bandwidth Management
You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-
mail and Video for example).
16.5 Subnet-based Bandwidth Management
You can create bandwidth classes based on subnets.
The following figure shows LAN subnets. You could configure one bandwidth class for
subnet A and another for subnet B.
