Example 2: Filtering
Traffic to a
Destination
In the following example, a flow classifier is defined to block access to the
Accounting network 192.1.0.0 (which includes subnetworks 192.1.1.0
and 192.1.2.0) from the Research and Development 168.20.30.0
subnetwork. The associated control for this classifier sets a service level of
drop to drop all traffic that is sent by the 168.20.30.0 subnet to the
Accounting network.
