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 the Configuring Summary section
Configure sub-class layers for the root class.
To add or delete child classes on an interface, click BW MGMT, then the Class Setup tab.
The screen appears as shown (with example classes).

budgets than the total of the budgets of their sub-classes. The sub-classes can borrow the extra
bandwidth as long as they have bandwidth borrowing enabled
