Configuration Examples for IP DSCP Marking and Classification

Example 7-3
traffic on the Gigabit Ethernet 1/0/0 interface to either class1 or class2. The router marks the packets by
setting the DSCP bits of class1 packets to DSCP 5 and by setting the DSCP bits of class2 packets to
DSCP 3 as indicated in the policy map named Silver.
Example 7-3
Router(config)# class-map class1
Router(config-cmap)# match qos-group 2
Router(config-cmap)# class class2
Router(config-cmap)# match access-group 108
Router(config-cmap)# exit
Router(config)# policy-map Silver
Router(config-pmap)# class class1
Router(config-pmap-c)# set ip dscp 5
Router(config-pmap-c)# class class2
Router(config-pmap-c)# set ip dscp 3
Router(config-pmap-c)# exit
Router(config-pmap)# exit
Router(config)# interface GigabitEthernet 1/0/0
Router(config-if)# service-policy output Silver
Example 7-4
the DSCP bits of outbound packets on the GigabitEthernet interface 1/0/0. If the packet DSCP bits are
set to 5, the router assigns the packet to the Voice class and gives the packet priority handling as indicated
in the policy map named Platinum. All intermediate routers provide low-latency treatment to the Voice
packets.
Example 7-4
Router(config)# class-map Voice
Router(config-cmap)# match ip dscp 5
Router(config-cmap)# exit
Router(config)# policy-map Platinum

Purpose
Exits policy-map class configuration mode.
Exits policy-map configuration mode.
Specifies the interface to which you want to attach the service
policy map. Enters interface configuration mode.
type is the type of interface (for example, serial).
number is the number of the interface (for example, 1/0/0).
Attaches the policy map you specify to the interface. The
router applies the service policy to packets on the interface in
either the input or output direction.
input indicates to apply the service policy to inbound
packets.
output indicates to apply the service policy to outbound
packets.
policy-map-name is the name of the policy map.
