QoS Class Rule

Add a QoS class rule with the following settings:

•Class: Choose the traffic class called “voice-inbound-class.”

•DSCP Marking: Choose the DSCP tag value (such as 46) for the inbound voice traffic depending on the QoS settings on your voice switch. For more information, see Understanding DSCP Values, page 171.

•CoS Marking: Choose the CoS tag value (such as 6) for the inbound voice traffic depending on the QoS settings on your voice switch.

STEP 3 Go to the Networking > QoS > WAN QoS > Policy Profile to Interface Mapping page to apply the inbound QoS policy profile on the WAN port. In this case, choose the QoS policy profile called “voice-inbound-profile” from the Inbound Policy Name drop-down list.

•Configuring LAN Queue Settings, page 167

•Configuring LAN QoS Classification Methods, page 167
