LABEL

DESCRIPTION

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-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.

 

 

Max

Select this check box to have the ZyXEL Device divide up all of the interface’s

Bandwidth

unallocated and/or unused bandwidth among the bandwidth classes that require

Usage

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).
