LABEL

DESCRIPTION

 

 

Class

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 or DMZ-to-DMZ traffic to pass

 

through the ZyWALL 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 (see Section

 

25.11 on page 406). The recommendation is to set this speed to match what the

 

device connected to the port can handle. For example, set the WAN interface speed

 

to 1000 kbps if the broadband device connected to the WAN port 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. See Section 25.7 on

 

page 400.

Maximize

Select this check box to have the ZyWALL divide up all of the interface’s unallocated

Bandwidth

and/or unused bandwidth among the bandwidth classes that require bandwidth. Do

Usage

not select this if you want to reserve bandwidth for traffic that does not match a

 

bandwidth class (see Section 25.7.4 on page 401) or you want to limit the speed of

 

this interface (see the Speed field description).
