Chapter 15 Bandwidth Management

The following table describes the priorities that you can apply to traffic that the ZyXEL 
Device forwards out through an interface.

Click Advanced > Bandwidth MGMT to open the screen as shown next. 

Enable bandwidth management on an interface and set the maximum allowed bandwidth for 
that interface. 

Figure 136   Bandwidth Management: Summary

The following table describes the labels in this screen. 

Table 98   Bandwidth Management Priorities

High

Typically used for voice traffic or video that is especially sensitive to jitter (jitter 

is the variations in delay).

Mid 

Typically used for “excellent effort” or better than best effort and would include 

important business traffic that can tolerate some delay.

Low

This is typically used for non-critical “background” traffic such as bulk transfers 

that are allowed but that should not affect other applications and users. 

Table 99   Media Bandwidth Management: Summary

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.
