been reset. The Reset ALL ONUs is convenient when multiple ONUs must be reset.
11.3.2.5 Refreshing the View
The Refresh button is used to refresh the Classification Scheme with the values currently stored in the ONU.
Once the configuration has been applied the ONU
MUST
be reset. This is because the GUI also applies both the Classification
Scheme and the FIFO Configuration together. This is an issue in the GUI that will be fixed in a future software release. Properly
designed hosts
MUST NEVER
apply a new Classification Scheme after changing the FIFO Configuration until
AFTER
the ONU has
been reset.
The Reset ALL ONUs is convenient when multiple ONUs must be reset.
11.4 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.
11.4.1 Selecting the Port for Filtering
The Port to Filter is selected using the Port drop down box.
11.4.2 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.
11.4.3 Constructing an ONU Filtering Rule Step 1.
Choose the Field Select. Field Selects defined by the ONU are given a descriptive
label. User Defined field selects are labeled User 1, User 2.., User N. All field select labels begin with an index value. The index
value correlates with the index value on the Edit Field panel.
