Creating Bandwidth Profiles
Bandwidth limiting determines the way in which the data is communicated with your host. The
purpose of bandwidth limiting is to provide a solution for limiting the traffic, thus preventing the
LAN users from consuming all the bandwidth on your WAN link.
For example, when a new connection is established by a device, the device will locate the firewall
rule corresponding to the following connections:
• If the rule has a bandwidth profile specification, then the device will create a bandwidth class
in the kernel.
• If multiple connections correspond to the same firewall rule, they will share the same class.
An exception occurs in the case of an individual type bandwidth profile if the classes are per
source IP. The source IP is the IP of the first packet of the connection.
The class is deleted when all the connections using the class expire.
To add a bandwidth profile:
1. Select Security from the main menu and Bandwidth Profile from the submenu. The
Bandwidth Profile screen will display.
2. Click add to add a new Bandwidth Profile. The Add New Bandwidth Profile screen will
display (see Figure 4-14 on page 4-24).
