QoS Class Dialog Box—Marking Tab
Use the Marking tab of the QoS Class dialog box to classify packets. Traffic
policers and shapers use these classifications to ensure adherence to the
contracted level of service. Downstream devices use this classification to identify
the packets and apply the appropriate QoS functions to them.
Note The Marking tab is unavailable when you define a QoS policy on the control
plane.
Navigation Path
Go to the QoS Class Dialog Box, page K-205, then click the Marking tab.

Field Reference
Table K-94 QoS Class Dialog Box—Marking Tab
Element Description
Enable Marking When selected, enables you to mark the traffic in this QoS class with a
specific precedence or DSCP value (regardless of any value the traffic might
have had when it first entered the device). This mark enables downstream
devices to identify the traffic and apply the appropriate QoS features to it.
When deselected, disables all marking options for the selected QoS class.
The traffic in this QoS class maintains its original precedence or DSCP
value, if any.
