Configure WAN QoS for Voice Traffic from LAN to WAN

Follow these steps to configure WAN QoS to manage the outbound voice traffic from LAN to WAN:

STEP 1 Go to the Networking > QoS > WAN QoS > Queue Settings page to determine how traffic in queues is handled for the WAN port.

a.Select the Low Latency Queuing (LLQ) radio button. LLQ allows delay-sensitive data (such as voice traffic) to be given preferential treatment over other traffic by letting the data to be de-queued and sent first.

a.Enter the amount of bandwidth assigned to Q1. Q1 has the highest priority and is always processed to completion before the lower priority queues.

b.Enter the percentage assigned to other queues (Q2 to Q6) that you want to use.

STEP 2 Go to the Networking > QoS > WAN QoS > Traffic Selector (Classification) page to add two traffic selectors used to classify the outbound voice and data traffic.

a. Add a traffic selector as follows to classify the outbound data traffic:

Class Name	data-outbound-class
VLAN	Default VLAN

b. Add a traffic selector as follows to classify the outbound voice traffic:

Class Name	voice-outbound-class
Source Address	voice_phone_ip

STEP 3 Go to the Networking > QoS > WAN QoS > QoS Policy Profile page to add a class-based QoS policy profile to manage the outbound voice and data traffic through the WAN port.

a. Add a WAN QoS policy profile as follows:

Policy Name	voice-outbound-profile
Apply this policy to	Outbound Traffic
