15.8 Bandwidth Management Rule Setup
You must use the Bandwidth Management Summary screen to enable bandwidth
management on an interface before you can configure rules for that interface.
Click Advanced > Bandwidth MGMT > Rule Setup to open the following screen.
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.
Max
Bandwidth
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.
Cancel Click Cancel to begin configuring this screen afresh.
