The table of traffic classes is displayed in the SD-WAN instance template and in the controller configuration menu:
To display the table of traffic classes in an SD-WAN instance template, go to the SD-WAN → SD-WAN instance templates section, click the SD-WAN instance template, and select the Traffic classes tab.
To display the table of traffic classes in the controller settings menu, go to the Infrastructure menu section, click Management → Configuration menu next to the controller, and go to the QoS section.
By default, the following traffic classes are created:
Best effort
Business normal
Business critical
Video
Conference
Signaling
Real time
Network control
Information about traffic classes is displayed in the following columns of the table:
Name is the name of the traffic class.
Internal tag is the internal tag of the traffic class.
Queue is the number of the queue to which traffic from the traffic class goes.
KOver is the overcommitment ratio of the traffic bandwidth, which sets the multiplier by which the bandwidth dedicated to the traffic class can be increased if the total bandwidth is not fully utilized.
Exclude when computing path indicates whether the bandwidth available to the traffic class is taken into account when calculating the route:
Yes
No
The following parameters are displayed in the lower part of the table:
Default traffic class is the traffic class in which all traffic is placed that is not included in other classes.
Control traffic class is the traffic class in which control traffic is placed that is used to manage solution components. We recommend assigning the highest priority to control traffic to make sure the network works reliably.
Maximum reserved bandwidth (%) is the percentage of the maximum traffic transfer rate that can be available for the traffic class.
Kaspersky SD-WAN does not support creating traffic classes, but you can edit the default traffic classes in the SD-WAN instance template or in the controller configuration menu.
Editing a traffic class
You can edit a traffic class in an SD-WAN instance template or in the controller configuration menu. If you edit a traffic class in an SD-WAN instance template, that traffic class is not modified in the controller configuration menu of already deployed SD-WAN instances.
Default traffic classes are suitable for most deployment scenarios, and we do not recommend editing them.
To edit a traffic class:
Edit a traffic class in one of the following ways:
If you want to edit the traffic class in an SD-WAN instance template, go to the SD-WAN → SD-WAN instance templates section, click the SD-WAN instance template, and select the Traffic classes tab.
If you want to edit the traffic class in the controller settings menu, go to the Infrastructure section, click Management → Configuration menu next to the controller, and go to the QoS section.
A table of traffic classes is displayed.
Click Edit.
In the Name column, enter the name of the traffic class.
In the Queue column, select the number of the queue into traffic of the selected class goes. The higher the value, the higher the priority of the traffic class. You cannot specify the same priority for multiple traffic classes.
In the KOver column, select the overcommitment ratio of the traffic bandwidth, which sets the multiplier by which the bandwidth dedicated to the traffic class can be increased if the total bandwidth is not fully utilized.
If you want to ignore the bandwidth available to the traffic class when building the route, select the Exclude when computing path check box. When this check box is selected, you cannot select the KOver ratio for the traffic class. By default, the check box is selected next to the Best effort traffic class.
In the Default traffic class drop-down list, select the traffic class in which all traffic is placed that is not included in other classes. By default, the Best effort traffic class is selected.
In the Control traffic class drop-down list, select the traffic class in which you want control traffic is placed. By default, the Network control traffic class is selected.
In the Maximum reserved bandwidth (%) drop-down list, select the percentage of the maximum traffic transfer rate that can be available for the traffic class. Range of values: 10 to 90. Default value: 90.
Click Ok.
The traffic class is modified.
If you have modified a traffic class in the SD-WAN instance template, in the upper part of the settings area, click Save to save the SD-WAN instance template settings.
