LABEL DESCRIPTION
WAN
LAN
DMZ 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
19.11 on page 310 ). 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-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 Section 19.7 on
page 305 .
Maximize
Bandwidth
Usage
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 19.8.1 on page 306 ) or you want to limit the speed of
this interface (see the Speed field description).
