Chapter 18 Media Bandwidth Management Advanced Setup

207

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 

). 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 

).

management class on the LAN. In order to limit the upload bandwidth, set the

 

bandwidth management class on the corresponding WAN interface.
