4.6.3 Designing the ONU Classification Scheme
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.
„ 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.
