The following table describes the labels in this screen.  
DSCP 
Mark(0~63)
This field is available only when you select IPv4 (0x0800) in the Ether Type field.
If you select Mark, enter a DSCP value with which the Device replaces the DSCP field in 
the packets.
If you select Unchange, the Device keep the DSCP field in the packets.
802.1Q Tag
If you select Remark, select a priority level (in the Ethernet Priority field) and enter a 
VLAN ID number (in the VLAN ID field) with which the Device replaces the IEEE 802.1p 
priority field and VLAN ID of the frames.
If you select Remove, the Device deletes the VLAN ID of the frames before forwarding 
them out.
If you select Add, the Device treat all matched traffic untagged and add a second 
priority level and VLAN ID that you specify in the Ethernet Priority and VLAN ID 
fields.
If you select Same, the Device keep the Ethernet Priority and VLAN ID in the packets.
To configure the Ethernet Priority, you can either select a priority number in the first 
drop-down list box (7 is the highest and 0 is the lowest priority) or select an application 
from the second drop-down list box which automatically maps to the corresponding 
priority number. (Key Net Traffic: 7; Voice: 6; Video: 5; IGMP: 4; Key Data: 3)
