Chapter 23 Media Bandwidth Management Advanced 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

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

These read-only labels represent the physical interfaces. Select an interface’s check box 

to enable bandwidth management on that interface. Bandwidth management applies to 

all traffic flowing out of the router through the interface, regardless of the traffic’s source.
Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the Prestige 

and be managed by bandwidth management.

Active

Select an interface’s check box to enable bandwidth management on that interface. 

Speed (kbps) Enter the amount of bandwidth for this interface that you want to allocate using 

bandwidth management. 
This appears as the bandwidth budget of the interface’s root class. The recommendation 

is to set this speed to match what the interface’s connection can handle. For example, 

set the WAN interface speed to 1000 kbps if the ADSL connection has an upstream 

speed of 1000 kbps.

Scheduler

Select either Priority-Based or Fairness-Based from the drop-down menu to control 

the traffic flow. 
Select Priority-Based to give preference to bandwidth classes with higher priorities. 
Select Fairness-Based to treat all bandwidth classes equally.  .

Bandwidth 

Usage

Select this check box to have the Prestige divide up all of the interface’s unallocated 

and/or unused bandwidth among the bandwidth classes that require bandwidth. Do not 

select this if you want to reserve bandwidth for traffic that does not match a bandwidth 

class or you want to limit the speed of this interface (see the Speed field description).
