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).
