An ONU classification scheme allows the operator to define a custom function to determine which packets
will be forwarded to each of the ONUs configured priority FIFOs. The classification function for a given
FIFO is composed of multiple independent rules. A rule consists of multiple ANDed expressions known as
clauses. Each rule is used to classify traffic into a single FIFO, 1 or more rules may be used to classify
traffic into the same FIFO.
11.3.1 Constructing an ONU Classification 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.
Step 2.
Choose an appropriate Operator. The operator tests the portion of the frame specified by the field select.
Step 3.
Choose an appropriate Lookup Value. This is the value that will be used by the operator in the
comparison. This step is only applicable to binary operators. If the operator selected is unary (such
as Field Exists) the Value field will be disabled.
Step 4.
Add the clause to the Rule Editor using the left arrow button. Note that the right arrow button can
be used to remove a selected clause from the Rule Editor.
