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.

To apply a Layer 2 policy on a Layer 3 interface:

  1. Configure an interface with an IP address or a VLAN sub-interface
    CONFIGURATION mode
    DellEMC(conf)# interface fo 1/49/1
    INTERFACE mode
    DellEMC(conf-if-fo-1/49/1)# ip address 90.1.1.1/16
  2. Configure a Layer 2 QoS policy with Layer 2 (Dot1p or source MAC-based) match criteria.
    CONFIGURATION mode
    DellEMC(conf)# policy-map-input l2p layer2
  3. Apply the Layer 2 policy on a Layer 3 interface.
    INTERFACE mode
    DellEMC(conf-if-fo-1/49/1)# service-policy input l2p layer2
