Table 85 Media Bandwidth Management: Summary

LABEL	DESCRIPTION
LAN	These read-only labels represent the physical interfaces. Select an interface’s check box
WLAN	to enable bandwidth management on that interface. Bandwidth management applies to
WAN	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-Basedor Fairness-Basedfrom the drop-down menu to control
	the traffic flow.
	Select Priority-Basedto give preference to bandwidth classes with higher priorities.
	Select Fairness-Basedto treat all bandwidth classes equally. .
Maximize	Select this check box to have the Prestige divide up all of the interface’s unallocated
Bandwidth	and/or unused bandwidth among the bandwidth classes that require bandwidth. Do not
Usage	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).
Back	Click Back to go to the main Media Bandwidth Management screen.
Apply	Click Apply to save your settings back to the Prestige.
Cancel	Click Cancel to begin configuring this screen afresh.

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 ).
