Chapter 13 Bandwidth Management 193

13.8 Bandwidth Management Rule Setup

See Section 13.1 on page 187 for background information. 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.

Figure 91 Bandwidth MGMT > Rule Setup

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.
