16.5.1 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 Configuration screen (see
Section 16.5 on page 163 ) 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
ZyXEL Device 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 Section 16.5 on page 163 for details).
The total of the configured bandwidth budgets for child-classes cannot exceed the configured
bandwidth budget speed of the parent class.
16.5.2 Configuring the Class Setup Screen
The class setup screen displays the configured bandwidth classes by individual interface.
Select an interface and click the buttons to perform the actions described next. Click “+” to
expand the class tree or click “-“to collapse the class tree. Each interface has a permanent root
class. The bandwidth budget of the root class is equal to the speed you configured on the
interface (see
Section 16.4 on page 160 to configure the speed of the interface). Configure
child-class layers for the root class.
To add or delete child classes on an interface, click
Media Bandwidth Management , then
Class Setup . The screen appears as shown (with example classes).
