18.9 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 18.8 on page 205 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).
The example reserves 10 Mbps of unbudgeted bandwidth for traffic that is not defined in the
bandwidth filters (see
Section 18.6.1 on page 202 ). The Administration and Sales USA
bandwidth classes each have bigger bandwidth budgets than the total of the budgets of their
child-classes. The child-classes can borrow the extra bandwidth as long as they have
bandwidth borrowing enabled (see
Section 18.7 on page 204 ).
