Applying Dscp And Vlan Match Criteria On A Service Queue - Dell S3048-ON Configuration Manual

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).
To configure IP VLAN and DSCP match criteria in a Layer 3 class map, and apply the class and policy maps to a service queue:
1 Create a match-any or a match-all Layer 3 class map, depending on whether you want the packets to meet all or any of the match
criteria. By default, a Layer 3 class map is created if you do not enter the layer2 option with the class-map command. When you
create a class map, you enter the class-map configuration mode.
CONFIGURATION mode
Dell(conf)#class-map match-all pp_classmap

CLASS-MAP mode
Dell(conf-class-map)#match ip vlan 5
4 Create a QoS input policy.
CONFIGURATION mode
Dell(conf)#qos-policy-input pp_qospolicy
5 Configure the DSCP value to be set on matched packets.
QOS-POLICY-IN mode
Dell(conf-qos-policy-in)#set ip-dscp 5
6 Create an input policy map.
CONFIGURATION mode

7 Create a service queue to associate the class map and QoS policy map.
POLICY-MAP mode
