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
Dell(conf)# interface fo 1/4
INTERFACE mode
Dell(conf-if-fo-1/4)# 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
Dell(conf)# policy-map-input l2p layer2
3. Apply the Layer 2 policy on a Layer 3 interface.
INTERFACE mode
Dell(conf-if-fo-1/4)# service-policy input l2p layer2
Applying DSCP and VLAN Match Criteria on a Service
Queue
You can configure Layer 3 class maps which contain both a Layer 3 Differentiated Services Code Point
(DSCP) and IP VLAN IDs as match criteria to filter incoming packets on a service queue on the switch.
To configure a Layer 3 class map to classify traffic according to both an IP VLAN ID and DSCP value, use
the match ip vlan vlan-id command in class-map input configuration mode. You can include the
class map in a policy map, and apply the class and policy map to a service queue using the service-
queue command. In this way, the system applies the match criteria in a class map according to queue
priority (queue numbers closer to 0 have a lower priority).
