20.11 Configuring Class Setup

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
sub-class layers for the root class.
To add or delete child classes on an interface, click BW MGMT, then the Class Setup tab.
The screen appears as shown (with example classes).

DESCRIPTION
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
20.11 on page 332). 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
page 327.
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 20.8.1 on page
this interface (see the Speed field description).
