Interface

Select an interface for which you want to set up bandwidth management classes. 
Bandwidth management controls outgoing traffic on an interface, not incoming. So, 

in order to limit the download bandwidth of the LAN users, set the bandwidth 

management class on the LAN. In order to limit the upload bandwidth, set the 

bandwidth management class on the corresponding WAN interface.

Bandwidth

This field displays whether bandwidth management on the interface you selected in 

the field above is enabled (Active) or not (Inactive).

After you select an interface, the bandwidth management classes configured for the 

interface display. The name and bandwidth display for each class.

Search Order

This list displays the interface’s active bandwidth management classes (the ones 

that have the bandwidth filter enabled). The ZyWALL applies the classes in the 

order that they appear here. Once a connection matches a bandwidth management 

class, the ZyWALL applies the class’s rules and does not check the connection 

against any other bandwidth management classes.
