Composite Operation Example; Dscp Table - Avaya W310 User Manual

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.

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 W310 changes
the value of the DSCP field in the packet to 5.
W310-1# ip qos-list 402
W310-1(QoS 402)# composite-operation 12
W310-1(QoS 402/cot 12)# name dscp5
Done!
W310-1(QoS 402/cot 12)# dscp 5
Done!
W310-1(QoS 402/cot 12)# cos no-change
Done!
W310-1(QoS 402/cot 12)# exit
W310-1(QoS 402)# ip-rule 3
W310-1(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
Operations for QoS
QoS rules on the list take precedence over the DSCP table. If a QoS rule other than the
default matches the packet, the W310 does not apply the DSCP table to the packet. The
W310 applies only the operation specified in the QoS rule.
To change an entry in the DSCP table:
1 Enter the context mode of a QoS list.
2 Type the command
you want to change its composite operation.
3 Type the command
operation you want to execute for packets with the specified DSCP value.
