24.12 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
to configure the speed of the interface). Configure
sub-class layers for the root class.
To add or delete child classes on an interface, click ADVANCED > BW MGMT > Class
Setup. The screen is shown here with example classes.
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
). 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.
The recommendation is to set this speed to match the interface’s actual transmission
speed. For example, set the WAN interface speed to 1000 kbps if your Internet
connection has an upstream transmission speed of 1 Mbps.
You can set this number higher than the interface’s actual transmission speed. This
will stop lower priority traffic from being sent if higher priority traffic uses all of the
actual bandwidth.
You can also set this number lower than the interface’s actual transmission speed. If
you do not enable Max Bandwidth Usage, this will cause the ZyWALL to not use
some of the interface’s available bandwidth.
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
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
) or you want to limit the speed of
this interface (see the Speed field description).
