DSCP field in the packets.

If you select Unchange, the Device keep the DSCP field in the packets.

field in the packets.

If you select Unchange, the Device keep the 802.1p priority field in the

You should have configured a queue in the Queue Setup screen already.

Criteria Configuration

Use the following fields to configure the criteria for traffic classification.

Basic

From Interface 

Select whether the traffic class comes from the LAN.

Ether Type

Select a predefined application to configure a class for the matched traffic.

If you select IP, you also need to configure source or destination MAC address, 
IP address, DHCP options, DSCP value or the protocol type.

If you select 8021Q, you can configure an 802.1p priority level and VLAN ID in 
the Others section.

Source

MAC Address

Select the check box and enter the source MAC address of the packet.

MAC Mask

Type the mask for the specified MAC address to determine which bits a 
packet’s MAC address should match. 

Enter “f” for each bit of the specified source MAC address that the traffic’s MAC 
address should match. Enter “0“ for the bit(s) of the matched traffic’s MAC 
address, which can be of any hexadecimal character(s). For example, if you set 
the MAC address to 00:13:49:00:00:00 and the mask to ff:ff:ff:00:00:00, a 
packet with a MAC address of 00:13:49:12:34:56 matches this criteria.

IP Address

Select the check box and enter the source IP address in dotted decimal 
notation. A blank source IP address means any source IP address. 

IP Subnet Mask

Enter the source subnet mask.

Port Range

If you select TCP or UDP in the IP Protocol field, select the check box and 
enter the port number(s) of the source. 

Exclude

Select this option to exclude the packets that match the specified criteria from 
this classifier.

Destination

MAC Address

Select the check box and enter the destination MAC address of the packet.

MAC Mask

Type the mask for the specified MAC address to determine which bits a 
packet’s MAC address should match. 

Enter “f” for each bit of the specified source MAC address that the traffic’s MAC 
address should match. Enter “0“ for the bit(s) of the matched traffic’s MAC 
address, which can be of any hexadecimal character(s). For example, if you set 
the MAC address to 00:13:49:00:00:00 and the mask to ff:ff:ff:00:00:00, a 
packet with a MAC address of 00:13:49:12:34:56 matches this criteria.
