Chapter 1 CLI Command Reference
set dscp
Set DSCP Values for IPv4 Packets Only
To set DSCP values for IPv4 packets only, use the ip keyword. Without the ip keyword, the match occurs
on both IPv4 and IPv6 packets.
Examples
Packet-marking Values and Table Map
In the following example, the policy map called “policy1” is created to use the packet-marking values
defined in a table map called “table-map1”. The table map was created earlier with the table-map (value
mapping) command. For more information about the table-map (value mapping) command, see the
table-map (value mapping) command page.
In this example, the DSCP value will be set according to the CoS value defined in the table map called
“table-map1”.
Router(config)# policy-map policy1
Router(config-pmap)# class class-default
Router(config-pmap-c)# set dscp cos table table-map1
Router(config-pmap-c)# end
The set dscp command is applied when you create a service policy in QoS policy-map configuration
mode. This service policy is not yet attached to an interface. For information on attaching a service
policy to an interface, refer to the “Modular Quality of Service Command-Line Interface” section of the
Cisco IOS Quality of Service Solutions Configuration Guide.
