Classifying Layer 2 Traffic on Layer 3 Interfaces

To process Layer 3 packets that contain Dot1p — (IEEE 802.1p) Packet classification (Layer 2 headers),
configure VLAN tags on a physical Layer 3 interface (that is configured with an IP address and is not
associated with any VLAN). You can also configure a VLAN subinterface over a physical underlying
interface and classify packets using the dot1p value.
To apply an input policy map to Layer 3 physical interfaces, use the service-policy input policy-
name layer 2 command in Interface Configuration mode.
To apply a Layer 2 policy on Layer 3 interfaces, perform the following:
1. Configure an interface with an IP address or a VLAN subinterface
CONFIGURATION mode
Dell(conf)# int fo 0/0
INTERFACE mode
Dell(conf-if-fo-0/0)# ip address 90.1.1.1/16
2. Configure the Layer 2 policy with Layer 2 (Dot1p or source MAC-based) classification rules.
CONFIGURATION mode
Dell(conf)# policy-map-input l2p layer2
3. Apply the Layer 2 policy on the Layer 3 interface.
INTERFACE mode
Dell(conf-if-fo-0/0)# service-policy input l2p layer2
Classifying Packets Based on a Combination of DSCP
Code Points and VLAN IDs
This functionality is supported on the Z9000 platform.
You can configure a classifier map, which contains both the Differentiated Services Code Point (DSCP)
and MAC VLAN IDs as parameters, for filtering packets that are received before they are forwarded or
dropped. You can now specify both DSCP-IP packet classification (Layer 3 headers) and Dot1p—(IEEE
802.1p) Packet classification (Layer 2 headers) as match criteria in a Layer 3 class map.
The type of the class map is determined during the creation of a class map. You can configure only the
dot1p value as the filter criterion in Layer 2 class maps and the DSCP value as the filter parameter in Layer
3 class maps. It was also possible to classify packets using both the Layer 2 attribute, dot1p value or MAC
VLAN, in a Layer 2 class map and the Layer 3 attribute, DSCP value, in a Layer 3 class map. However, it
was not possible to configure both dot1p or MAC VLAN, and DSCP values in the same Layer 2 or Layer 3
class map.
