cpu traffic qos dscp
When the cpu traffic qos dscp global configuration command is configured with table maps, you can
configure only one map from value at a time—DSCP, precedence, or CoS. A new configuration
overwrites the existing configuration. Packets marked by this command can be classified and queued by
an output policy map based on the marked DSCP or precedence value.
You cannot configure a map from value of both DSCP and precedence. A new configuration overwrites
the existing configuration.
Examples
This example shows how to configure egress queuing based on the DSCP value of CPU-generated IP
packets.
The sample configuration has these results:
•
•
•
•
•
•
•
Switch(config)# cpu traffic qos dscp dscp
Class:
Switch(config)# class-map match-any video
Switch(config-cmap)# match ip dscp af41 af42 af43
Switch(config-cmap)# exit
Switch(config)# class-map match-any voice
Switch(config-cmap)# match ip dscp ef
Switch(config-cmap)# exit
Switch(config)# class-map match-any network-internetwork-control
Switch(config-cmap)# match ip dscp 48 56
Switch(config-cmap)# exit
Policy:
Switch(config)# policy-map output-policy
Switch(config-pmap)# class voice
Switch(config-pmap-c)# priority
Switch(config-pmap-c)# police cir 10000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class video
Switch(config-pmap-c)# bandwidth percent 40
Switch(config-pmap-c)# exit
Switch(config-pmap)# class network-internetwork-control
Switch(config-pmap-c)# bandwidth percent 10
Switch(config-pmap-c)# exit
Switch(config-pmap)# class class-default
Switch(config-pmap-c)# bandwidth percent 30
Switch(config-pmap-c)# exit

2-64
All CPU-generated IP traffic queues on the egress port, based on its IP DSCP value, and the
configured output policy map output-policy.
All IP SLA or TWAMP probes with the DSCP value ef to simulate voice traffic are assigned to the
voice class.
All IP SLA or TWAMP probes with the DSCP values af41, af42 and af43 to simulate video traffic
are assigned to the video class.
All IP control protocol traffic with the DSCP values 48 and 56 are assigned to the
network-internetwork-control class.
The rest of the IP traffic is assigned to the default class.
All CPU-generated non-IP traffic is statically mapped to a fixed queue on the egress port.
All CFM traffic is queued to the default class because there is no class based on CoS.
