11.2.3 Editing a Lookup Engine Field
Lookup Engine Fields may only be modified if they are not currently being used in any rule. The ONU
keeps track of the fields currently being used by maintaining a reference count. This reference count is
displayed in the Field Select Table. To edit a field with zero reference count follow the procedure below.
Step 1.
Click on the Field Select index to be edited.
Step 2.
Using the Layer Sel drop down list, select an appropriate frame format. The ONU will use the
frame format to qualify the field select value.
Step 3.
Using the Edit Tool, drag a box over the field select by depressing the mouse button at the start of
the field dragging it to the end of the field and then releasing the mouse button.
Notice that after the field has been selected, the Name will change to reflect the selected value.

Most ONU classification engines are configured on a per port basis. However, the TK3701
supports only upstream and downstream classification. The Port field allows the operator to
choose the set of field selects to modify. Depending on the port that is chosen the provisioning
may be different. For ONUs supporting only upstream and downstream classification, the EPON
port designates downstream, and selecting either User Port selects upstream.
