You can delete a traffic classifier in an SD-WAN instance template or in the controller configuration menu. If you delete a traffic classifier in an SD-WAN instance template, that traffic classifier is not deleted in the controller configuration menu of already deployed SD-WAN instances.
Deleted traffic classifiers cannot be restored.
To delete a traffic classifier:
Delete a traffic classifier in one of the following ways:
If you want to delete a traffic classifier 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 classifiers tab.
If you want to delete a traffic classifier in the controller settings menu, go to the Infrastructure section, click Management → Configuration menu next to the controller, and go to the QoS section and select the Traffic classifiers tab.
A table of traffic classes is displayed.
Click Management → Delete next to the traffic classifier that you want to delete.
In the confirmation window, click Delete.
The traffic classifier is deleted and is no longer displayed in the table.
If you have deleted a traffic classifier in the SD-WAN instance template, in the upper part of the settings area, click Save to save the SD-WAN instance template settings.
