Applying Layer 2 Match Criteria on a Layer 3 Interface
To process Layer 3 packets that contain a dot1p (IEEE 802.1p) VLAN Layer 2 header, configure VLAN tags
on a Layer 3 port interface which is configured with an IP address but has no VLAN associated with it. You
can also configure a VLAN sub-interface on the port interface and apply a policy map that classifies
packets using the dot1p VLAN ID.
To apply an input policy map with Layer 2 match criteria to a Layer 3 port interface, use the service-
policy input policy-name layer 2 command in Interface configuration mode.
