Figure 105   Bandwidth Management: Summary

The following table describes the labels in this screen. 

You must use the Bandwidth Management Summary screen to enable bandwidth 
management on an interface before you can configure rules for that interface.

Table 75   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. 
The recommendation is to set this speed to match the interface’s actual transmission 

speed. For example, set the WAN interface speed to 1000 kbps if your Internet 

connection has an upstream transmission speed of 1 Mbps.        
You can set this number higher than the interface’s actual transmission speed. This 

may stop lower priority traffic from being sent if higher priority traffic uses all of the 

actual bandwidth. 
You can also set this number lower than the interface’s actual transmission speed. If 

you do not enable Max Bandwidth Usage, this will cause the ZyXEL Device to not use 

some of the interface’s available bandwidth.

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).
