21.5  Application and Subnet-based Bandwidth Management
You could also create bandwidth classes based on a combination of a subnet and an 
application. The following example table shows bandwidth allocations for application specific 
traffic from separate LAN subnets.
21.5.1  Bandwidth Management Priorities
Traffic with a higher priority gets through faster while traffic with a lower priority is dropped 
if the network is congested. The following table describes the priorities that you can apply to 
traffic that the ZyXEL Device forwards out through an interface.   
21.6  Configuring Bandwidth Management (General) 
Click Advanced > Bandwidth MGMT to open the screen as shown next. 
Use this screen to enable or disable bandwidth management, and to enable or disable 
automatic traffic classification.

Table 133   Bandwidth Management Priorities
PRIORITY 
DESCRIPTION
High
Typically used for voice traffic or video that is especially sensitive to jitter (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.
