ISG50 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.

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 ISG50 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 ISG50 resets the 
statistics.

Select None to not create a log when the ISG50 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 ISG50 send a log or alert for this event periodically. 
Specify how often (from 1 to 65535 minutes) to send the log or alert.
