The following table describes the labels in this screen. 

Table 120   Media Bandwidth Management: Summary

Interface

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 ZyXEL 

Device 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 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.

Max 

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).
