Cisco Catalyst 3650 Series User Manual

When you configure the set dscp coscommand, note the following: The CoS value is a 3-bit field, and the
DSCP value is a 6-bit field. Only the three bits of the CoS field are used.
When you configure the set dscp qos-group command, note the following:
•
The valid range for the DSCP value is a number from 0 to 63. The valid value range for the QoS group
is a number from 0 to 99.
•
If a QoS group value falls within both value ranges (for example, 44), the packet-marking value is copied
and the packets is marked.
•
If QoS group value exceeds the DSCP range (for example, 77), the packet-marking value is not be copied
and the packet is not marked. No action is taken.
The set qos-group command cannot be applied until you create a service policy in policy-map configuration
mode and then attach the service policy to an interface or ATM virtual circuit (VC).
To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use
the end command.

Device(config-cmap)# exit
Device(config)# policy policy_ftp
Device(config-pmap)# class ftp_class
Device(config-pmap-c)# set dscp 10
