ZyWALL USG 50 User’s Guide

A Virtual Local Area Network (VLAN) divides a physical network into multiple 
logical networks. The standard is defined in IEEE 802.1q.

Figure 160   Example: Before VLAN

In this example, there are two physical networks and three departments A, B, and 
C. The physical networks are connected to hubs, and the hubs are connected to 
the router.

Alternatively, you can divide the physical networks into three VLANs.

Actions when over 
% of time budget 
or % of data 
budget 

Specify the actions the ZyWALL takes when the specified percentage 
of time budget or data limit is exceeded. Enter a number from 1 to 99 
in the percentage fields. If you change the value after you configure 
and enable budget control, the ZyWALL resets the statistics.

Select None to not create a log when the ZyWALL takes this action, 
Log to create a log, or Log-alert to create an alert log. If you select 
Log or Log-alert you can also select recurring every to have the 
ZyWALL send a log or alert for this event periodically. Specify how 
often (from 1 to 65535 minutes) to send the log or alert.
