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
2. Configure a DSCP value as a match criterion.
CLASS-MAP mode
Dell(conf-class-map)#match ipdscp 5
3. Configure an IP VLAN ID as a match criterion.
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
Dell(conf)#policy-map-input pp_policmap
7. Create a service queue to associate the class map and QoS policy map.
POLICY-MAP mode
Dell(conf-policy-map-in)#service-queue 0 class-map pp_classmap qos-policy
pp_qospolicy
