Examples of
Classifiers and
Controls
The following six examples show different ways to implement flow and
nonflow classifiers and their associated controls.
Example 1: Traffic to
and from a Specific
Server
In the first example, a flow classifier is defined with two address and port
patterns (filters) to classify traffic from subnets of the 168.101.0.0
network
to the database server 168.101.162.151, and traffic from the
server to the subnets. This kind of configuration could be called a to/from
classifier. The control applied to this classifier gives the traffic to and from
the server high priority.
