Examples
This example shows how to set the IP DSCP ToS byte to 8 in the policy map called policy1:
Router(config)# policy-map policy1
Router(config-cmap)# class class1
Router(config-cmap)# set ip dscp 8
All packets that satisfy the match criteria of class1 are marked with the IP DSCP value of 8. How packets
that are marked with the IP DSCP value of 8 are treated is determined by the network configuration.
This example shows that after you configure the settings that are shown for voice packets at the edge of
the network, all intermediate routers are then configured to provide low-latency treatment to the voice
packets:
Router(config)# class-map voice
Router(config-cmap)# match ip dscp ef
Router(config)# policy qos-policy
Router(config-cmap)# class voice
Router(config-cmap)# priority 24

For hardware-switched traffic, Policy Feature Card (PFC) QoS does not support the bandwidth,
priority, queue-limit, or random-detect policy-map class commands. You can configure these
commands because they can be used for software-switched traffic.
PFC QoS does not support the set mpls or set qos-group policy-map class commands.
PFC QoS supports the set ip dscp and set ip precedence policy-map class commands (see the
"Configuring Policy Map Class Marking" section in the Cisco 7600 Series Router Cisco IOS
Software Configuration Guide).
You cannot do all three of the following in a policy-map class:
– Mark traffic with the set ip dscp or set ip precedence (policy-map configuration) commands
– Configure the trust state
– Configure policing
In a policy-map class, you can either mark traffic with the set ip dscp or set ip precedence
(policy-map configuration) commands or do one or both of the following:
– Configure the trust state
– Configure policing
Description
Accesses QoS policy-map configuration mode to configure the QoS policy
map.
Attaches a policy map to an interface.
