The Class Setup Screen

Use this screen to add, edit or delete QoS classifiers. A classifier groups traffic into

data flows according to specific criteria such as the source address, destination

address, source port number, destination port number or incoming interface. For

example, you can configure a classifier to select traffic from the same protocol

port (such as Telnet) to form a flow.

You can give different priorities to traffic that the Device forwards out through the

WAN interface. Give high priority to voice and video to make them run more

smoothly. Similarly, give low priority to many large file downloads so that they do

not reduce the quality of other applications.

DESCRIPTION

Add

Click

this button to create a new classifier.

Order

This field displays the index number of the classifier.

Active

Select the check box to enable the classifier.

Class Name

This is the name of the classifier.

Classification

Criteria

This shows criteria specified in this classifier, for example the interface

from which traffic of this class should come and the source MAC

address of traffic that matches this classifier.

This is the interface through which traffic that matches this classifier is

forwarded out.

DSCP Mark

This is the DSCP number added to traffic of this classifier.

802.1P Mark

This is the IEEE 802.1p priority level assigned to traffic of this

classifier.

VLAN ID Tag

This is the VLAN ID number assigned to traffic of this classifier.

Class Name

Enter a descriptive name of up to 20 printable English keyboard

characters, including spaces.

Classification

Order

Select an existing number for where you want to put this classifier to

move the classifier to the number you selected after clicking

Apply

.

Select

Last

to put this rule in the back of the classifier list.

Forward to

Interface

Select a WAN interface through which traffic of this class will be

forwarded out. If you select

Unchange

, the Device forward traffic of

this class according to the default routing table.

DSCP Mark

This field is available only when you select the

Ether Type

check box.

If you select

Mark

, enter a DSCP value with which the Device replaces

the DSCP field in the packets.

If you select

Auto Mapping

and there is a VLAN tag carried in the

matched packets, the Device will replace the IP ToS field with the

802.1p priority field.

If you select

Unchange

, the Device keep the DSCP field in the

packets.

802.1p Mark

Select a priority level with which the Device replaces the IEEE 802.1p

priority field in the packets.

If you select

Unchange

, the Device keep the

802.1p priority field in

the packets.

VLAN ID Tag

If you select

Remark

, enter a VLAN ID number (between 1 and 4095)

with which the Device replaces the 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 VLAN ID.

If you select

Unchange

, the Device keep the VLAN ID in the packets.

To Queue

Select a queue that applies to this class.

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 from which Ethernet port or wireless interface traffic of this

class should come.

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.

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.

TCP/UDP 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.

IP Address

Select the check box and enter the destination IP address in dotted

decimal notation. A blank source IP address means any source IP

address.

IP Subnet

Mask

Enter the destination subnet mask.

TCP/UDP 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.

Others

802.1P

This field is available only when you select

802.1Q

in the

Ether Type

field.

Select this option and select a priority level (between 0 and 7) from
