Ingress Layer 2 Configuration 
Layer 2 page enables you to map an incoming packet with VLAN priority to CoS. This feature is 
only configurable on the WAN interfaces as VLAN is only supported on the WAN side in the 
current software release. 
 
Interface 
Select the WAN interface here to configure the CoS for incoming traffic. Only 
WAN interface can be selected as VLAN is currently supported only on the WAN 
side. 
Class of Service 
The selections are (in the order of descending priority): CoS1, CoS2, CoS3, 
CoS4, CoS5, and CoS6. 
User Priority 
The selections are 0, 1, 2, 3, 4, 5, 6, 7. 
To configure Ingress Layer 2 to CoS: 
1. 
From Interface drop-down box, select PPPoE to configure QoS on this WAN interface. 
2. 
Select CoS1 in Class of Service and 5 in Priority Bits. 
Any packets with priority marking 5 is mapped to CoS1, the highest priority that is normally 
given to the voice packets. 
3. 
Click Apply to temporarily activate the settings. 
4. 
Select CoS2 in the Class of Service field and 1 in the Priority Bits field. 
Any packets that have priority bits of 1 are mapped to CoS2, which is the second highest 
priority. This is given to the high priority packets such as video.
