FIELD
LAN These read-only labels represent the physical interfaces. Select an interface's check box
WAN to enable bandwidth management on that interface. Not all interfaces are available on
DMZ every ZyWALL.
WLAN
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 25.8.2).
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 25.5.
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 not
Usage select this if you want to reserve bandwidth for traffic that does not match a bandwidth
class (see section 25.6.1) or you want to limit the speed of this interface (see the Speed
field description).
Click Apply to save your changes back to the ZyWALL. Click Reset to begin configuring this screen afresh.
Bandwidth Manager Class Setup
25.8.2
The class setup screen displays the configured bandwidth classes by individual interface. Select an interface
and click the buttons to perform the actions described next. Click "+" to expand the class tree or click "-" to
collapse the class tree. Each interface has a permanent root class. The bandwidth budget of the root class is
equal to the speed you configured on the interface (see section 25.8.1 to configure the speed of the
interface). Configure child-class layers for the root class.
Click Advanced, BW Manager, and then the Class Setup tab to go to the screen shown next (with
example classes).
The example reserves 15 Mbps of unbudgeted bandwidth for traffic that is not defined in the bandwidth
filters (see section 25.6.1). The Administration, Sales USA and Sales Asia bandwidth classes each have
