You apply the multifield classifier's firewall filter as an input filter on each customer-facing
or host-facing interface that needs the filter. The incoming interface is ge-1/0/0 on Device
R1. The classification and queue assignment is verified on the outgoing interface. The
outgoing interface is Device R1's ge-1/0/2 interface.
