Summary
The Traffic Shaping page is used to set up Smart Queue Management (SQM) instances which can limit the download and upload speeds of selected network interfaces.
This manual page provides an overview of the Traffic Shaping windows in {{{name}}} devices.
If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.
Smart Queue Management
The Smart Queue Management section contains a list of existing SQM instances and can be used manage them (edit/delete/enable/disable). By default the list is empty:
To add a new instance and begin editing, look below to the Add New SQM Configuration section and:
- enter a custom name in the 'Name' field;
- click the 'Add' button;
- click the 'Edit' button next to newly created instance.
Refer to the sections below for information on editing SQM instances.
Basic Settings
The Basic Settings section is used to set download and upload speed limits for a selected network interface.
Field | Value | Description |
---|---|---|
Enabled | off | on; default: off | Turns the SQM configuration on or off. |
Interface name | network interface; default: br-lan (lan) | Selects to which interface this SQM configuration will apply. Additional note: consider reading the [[{{{name}}}__QoS#Additional_notes|Additional notes]] section before limiting speeds on selected interfaces. |
Download speed (kbit/s) | integer [0..9999999999999999]; default: none | Limits the download speed (ingress) of the selected interface to the value specified in this field. |
Upload speed (kbit/s) | integer [0..9999999999999999]; default: none | Limits the upload speed (egress) of the selected interface to the value specified in this field. |
Advanced Settings
The Advanced Settings section describes the internal logic of the SQM configuration.
Field | Value | Description |
---|---|---|
Queuing disciplines usable on this system | cake | fq_codel; default: cake | Queue management logic type. Look to the row below for detailed information. |
Queue setup script | layer_cake.qos | piece_of_cake.qos | simple.qos | simplest.qos | simplest_tbf.qos; default: piece_of_cake.qos | Describes the queue management logic.

Additional notes
If you set SQM for the LAN interface, the direction logic is naturally inverted. (egress means "from router towards LAN" = in practice "download from WAN forwarded to LAN".
Also, please consider that limiting the speed of certain interfaces may limit the speed of other interfaces as well. For example, if you limit the download and upload speeds of the default LAN interface (br-lan) to 50 000 kbps (50 Mbps) this will affect the speeds between:
- Ethernet LAN machines (including the device)
- Ethernet LAN machines and WAN*
* Since LAN machines communicate with WAN servers over the device which is also considered a LAN machine, LAN-to-WAN and WAN-to-LAN speeds are also affected.
The table below demonstrates speed changes between some of the main default network interfaces if br-lan speed is set to 50 Mbps.
Ethernet LAN | Ethernet WAN | Mobile WAN | |
---|---|---|---|
Ethernet LAN | 50 | 50 | 50 |
Ethernet WAN | 50 | unchanged | unchanged |
Mobile WAN | 50 | unchanged | unchanged |
Changing the speeds of other network interfaces may also affect more than one interface. However, the Ethernet LAN interface (br-lan) is related to most interfaces. Therefore, it is advised to limit the speeds of other interfaces in order to achieve more precise results (unless, of course, your goal to is to limit the speed of br-lan).
Another example to consider is limiting WAN interface speeds since that is the most widely implemented use case and affects less interface-to-interface relationships. For instance, limiting Ethernet WAN (eth1) speed to 50 Mbps would produce the following results:
Ethernet LAN | Ethernet WAN | Mobile WAN | |
---|---|---|---|
Ethernet LAN | unchanged | 50 | unchanged |
Ethernet WAN | 50 | unchanged | unchanged |
Mobile WAN | unchanged | unchanged | unchanged |
Please take caution when using SQM to limit speeds in order to avoid unexpected results.
