18.4 Classifier Example
The following screen shows an example where you configure a classifier that identifies all traffic from MAC address 00:50:ba:ad:4f:81 on port 2.
After you have configured a classifier, you can configure a policy (in the Policy screen) to define action(s) on the classified traffic flow.
