19.8  Bandwidth Management Rule Setup   
You must use the Bandwidth Management Summary screen to enable bandwidth 
management on an interface before you can configure rules for that interface.
Click Advanced > Bandwidth MGMT > Rule Setup to open the following screen.
Figure 160   Bandwidth Management: Rule Setup
The following table describes the labels in this screen.  
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 10000 kbps if the DSL connection 
has an upstream speed of 10Mbps.
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 ZyXEL Device 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).
Apply Click Apply to save your settings back to the ZyXEL Device.
Cancel Click Cancel to begin configuring this screen afresh.
