23.9 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
the Configuring Summary section 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 Reserving Bandwidth for Non-Bandwidth Class Traffic section ).
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
the Bandwidth Borrowing
section ).
Table 85 Media Bandwidth Management: Summary
LABEL DESCRIPTION
LAN
WLAN
WAN 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. .
Maximize
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).
