DSCP table

To create or edit a composite operation:
1
Enter the context of a QoS list.
2
Type the
or higher, since numbers 1 through 11 are assigned to pre-configured lists.
3
Use one or more of the following commands to set the parameters of the composite operation:
—
dscp
the DSCP field, use the argument
—
cos
CoS field, use the argument
4
Use the
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.

Composite operation example

The following commands create a new composite operation called dscp5 and assign the new composite
operation to rule 3 in QoS list 402. If the packet matches a rule, the G350 changes the value of the DSCP
field in the packet to 5.
G350-001# ip qos-list 402
G350-001(QoS 402)# composite-operation 12
G350-001(QoS 402/cot 12)# name dscp5
Done!
G350-001(QoS 402/cot 12)# dscp 5
Done!
G350-001(QoS 402/cot 12)# cos no-change
Done!
G350-001(QoS 402/cot 12)# exit
G350-001(QoS 402)# ip-rule 3
G350-001(QoS 402/rule 3)# composite-operation dscp5
Done!
DSCP table
Each QoS list includes a DSCP table. A DSCP lists each possible DSCP value, from 0 to 63. For each
value, the list specifies a composite operation. See
page 171.
QoS rules on the list take precedence over the DSCP table. If a QoS rule other than the default matches
the packet, the G350 does not apply the DSCP table to the packet. The G350 applies only the operation
specified in the QoS rule.
To change an entry in the DSCP table:
1
Enter the context of a QoS list.
2
Type the command
change its composite operation.
3
Type the command
want to execute for packets with the specified DSCP value.
