Figure 194 Bandwidth Management: Summary

The following table describes the labels in this screen.

Speed (kbps)

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.

Select an interface's check box to enable bandwidth management on that interface.

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

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.

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. See

Select this check box to have the ZyWALL 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 (see

Section 25.7.4 on page
