Traffic Classes

Traffic classes channel Internet traffic to a desired queue based on the service. The service can be Layer 4 TCP or UDP port application, Source or Destination IP Address, DSCP, Receive interface, OS, and Device type.

To configure the Traffic Classes, follow these steps:

Procedure

Step 1

Click QoS > Traffic Classes.

Step 2

In the Traffic Table, click Add (or select the row and click Edit) and enter the following:

Class Name – Enter the name of the defined class.
Description – Enter the description of the class.
In Use – Traffic class record is being used by a queuing policy.

Step 3

In the Service Table, click Add (or select the row and click Edit) and enter the following information:

Service Name

Enter the name of the service.

Receive Interface

Select an interface (WAN1, WAN2, USB1, USB2, LAN1, LAN2, LAN3, LAN4, or VLAN1) from the drop-down list.

IP Version

Select IPv4, IPv6, or Either (if you do not know the version of the traffic).

Source IP

Enter the source IP address of the traffic.

Destination IP

Enter the destination IP address of the traffic.

Service/Application

Service: Select the name of the service to apply on the traffic record. Provide the source and destination ports.
Application: Select the application to apply on the traffic record. Select the application behavior and category.

Note	The Application rules can not be configured until the user enables the Application Control in the Security/Application Control page.

Device Type

Select the type of device from the drop-down list, from which the traffic is initiated.

OS Type

Select the Operating System of the device from the drop-down list, from which the traffic is initiated.

Match DSCP

The DSCP matches the traffic class value in the IPv6 header for the IPv6 traffic. The traffic class value is 4 times the configured value. For example, if the user configures the matched DSCP as 10, then rewrite the DSCP as 18. The rule matches the IPv6 flows with the traffic class value 40 and rewrites the DSCP to 72. Select the DSCP value from the drop-down list, to be matched with the DSCP value in the incoming packets.

Rewrite DSCP

Select the DSCP value from the drop-down list, to be replaced with, in incoming packets.

Step 4
