Quality of Service
9.1.2 Filter Configuration
Filters in QoS help in classification of traffic, and assigning the traffic to a specific HTB class. These filters use IP parameters like Source IP, Destination IP, Protocol, Source Port and Destination Port. The packets that match a filter configuration is placed in the class specified with the Class ID parameter and will receive the specified traffic treatment.
Multiple filters can be configured for the same Class ID. For example, consider a scenario where the administrator wants to ensure that HTTP and Email traffic together do not exceed 100kbps. In this case, a HTB Class can be configured with a Maximum Rate of 100kbps, and two filters (one for HTTP and one for Email traffic) can be added for the same HTB Class.
Select QoS → Filter Configuration to configure the QoS Filter Configuration as explained below.

|
Source | The Source IP. |
| • Any - If selected the filter will be applied for any source address. |
| • Subnet - If selected the user needs to configure specific Source IP |
| address with subnet. |
IP Address | Enter the Source IP Subnet |
|
|
Destination | The Destination IP. |
| • Any - If selected the filter will be applied for any destination address. |
| • Subnet - If selected the user needs to configure specific destination IP |
| address with subnet. |
IP Address | Enter the Destination IP Subnet |
|
|
Protocol | Select the Protocol to filter the network traffic. When Other is selected |
| enter the protocol number (between 1 and 255). |
|
|
Source Port No | Enter the Source port number (value between 1 and 65535) to specify the |
| type of application for which this filter is used. Source port value of zero |
| indicates "Any" Source Port. This field is effective when TCP/UDP is |
| selected as the Protocol. |
Destination Port No Enter the Destination port number (value between 1 and 65535) to specify the type of application for which this filter is used. Destination port value
| of zero indicates "Any" Source Port. This field is effective when |
| TCP/UDP is selected as the Protocol. |
