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	Some locally generated packets might not have been classified and thus do not have a CoS value,
Packet	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, and 7.
