19.12 Configuring Class Setup
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 19.11 on page 335 to configure the speed of the interface). Configure
sub-class layers for the root class.
To add or delete child classes on an interface, click ADVANCED > BW MGMT > Class
Setup. The screen is shown here with example classes.

bandwidth class (see Section 19.7.4 on page 331) or you want to limit the speed of
this interface (see the Speed field description).
