4.6.4 Provisioning Filtering Rules
Filtering Rules and Classification Rules work in apposing directions to achieve the same
ultimate goal: control the user’s access to the PON. In the previous section we learned that
Classification Rules are used to allow certain classes of traffic into the ONU data path. As
you might imagine, Filtering Rules serve the opposite purpose, blocking certain classes of
traffic from entering an ONU Port. Filtering rules use the same hardware resources, Field
Selects, Operators, and Precedence values as Classification Rules and are constructed in
a similar fashion. A Classification Rule can override a Filtering Rule by setting its
precedence higher.
„ Selecting the Port for Filtering
The Port to Filter is selected using the Port drop down box.
„ Using the Rule Grid
The Filtering Panel Rule Grid is almost identical to the Classification Panel Rule Grid,
except that the Q column is absent, as it is not required.
