LABEL DESCRIPTION
Interface 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 traffic to pass through the ZyXEL
Device 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. 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.
If this number is higher than the interface’s actual transmission speed, and you
configure bandwidth rules for all of the bandwidth, higher priority traffic could use all of
the bandwidth so lower priority traffic does not get through.
Note: Unless you enable Max Bandwidth Usage, the ZyXEL Device
only uses up to the amount of bandwidth that you configure here.
The ZyXEL Device does not use any more bandwidth for the
interface’s connections, even if the interface has more outgoing
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.

Usage
Select this check box to have the ZyXEL Device 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 or you want to limit the speed of this interface (see the Speed
field description).
Apply Click Apply to save your settings back to the ZyXEL Device.
