Policy lists
CoS: The operation sets the Ethernet IEEE 802.1p CoS: field in the packet to the value listed
in this column
DSCP: The operation sets the DSCP: field in the packet to the value listed in this column
Trust: Determines how to treat packets that have been tagged by the originator or other
network devices. If the composite operation is set to Trust-DSCP, the packet's CoS tag is set
to 0 before the QoS list rules and DSCP map are executed. If the composite operation is set
to CoSX, the DSCP map is ignored, but the QoS list rules are executed on the Ethernet
IEEE 802.1p CoS field. (For example, the composite operation CoS3 changes the CoS field
to 3.) If the composite operation is set to Trust-DSCP-CoS, the operation uses the greater of
the CoS or the DSCP value. If the composite operation is set to No Change, the operation
makes no change to the packet's QoS tags.
Configuring composite operations
About this task
You can configure additional composite operations for QoS lists. You can also edit composite
operations that you configured. You cannot edit pre-configured composite operations.
Note:
You cannot configure additional composite operations for access control lists, since all
possible composite operations are pre-configured.
Procedure
1. Enter the context of a QoS list.
2. Enter composite-operation followed by an index number.
3. Use one or more of the following commands to set the parameters of the composite
4. Enter name, followed by a text string, to assign a name to the composite

The number must be 12 or higher, since numbers 1 through 11 are assigned to pre-
configured lists.
operation:
• dscp - to ignore the DSCP field, use the argument no change, or enter no
dscp.
• cos - to ignore the CoS field, use the argument no change, or enter no
cos.
operation.
You must assign a name to the composite operation, because when you attach the
composite operation to a rule, you use the name, not the index number, to identify
the composite operation.
