Description

Feature/Application:

CFS 4.0 integrates Application Firewall infrastructure to implement more granular, flexible and powerful content filter policy control. This article describes the method Per Action/Policy to configure bandwidth aggregation method on CFS categories, multiple policies will be subject to a single aggregate bandwidth management settings when they share the same action.

Resolution

Procedure:

The following sections will be described to configure CFS bandwidth aggregation.

Enabling CFS

Per Policy Method – The bandwidth limit specified in a policy is applied individually to each policy

Example: two policies each have an independent limit of 500kb/s, the total possible bandwidth between those two rules is 1000kb/s

Per Action Aggregate Method – The bandwidth limit action is applied (shared) across all policies to which it is applied

Example: two policies share a BWM limit of 500kb/s, limiting the total bandwidth between the two policies to 500kb/s

Creating CFS Profile object
