User Manual 
Layer 2 
The Egress Layer 2 page allows you to map the CoS of an outgoing packet to user priority 
bits, which is honored by the VLAN network. Again, this feature is only configurable on 
the WAN interfaces as VLAN is only supported on the WAN side in the current release. 
 
Layer 2 
Field 
Description 
Interface 
Select the WAN interface to configure the QoS for outgoing packets; LAN interface 
cannot be selected as VLAN is currently supported on the WAN side only. 
Unclassified 
Packet 
Some locally generated packets might not have been classified and thus do not have 
a CoS value, such as PPP control packet and ARP packet. You can define the CoS for 
all unclassified outgoing packets on layer 2 using this field, which will then pick up 
the user priority bits based on the mapping rules you create. The selections are (in 
the order of descending priority): CoS1, CoS2, CoS3, CoS4, CoS5, and CoS6. The 
default value is CoS1 (recommended). 
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.
