Alternatively, select to have classifier rules applied according to the layer of the item configured
a uto
in the rule. Layer-4 items have the highest priority, and layer-2 items has the lowest priority. For
example, you configure a layer-2 item (VLAN ID) in classifier A and configure a layer-3 item (source IP
address) in classifier B. When an incoming packet matches both classifier rules, classifier B has priority
over classifier A.
