SD-WAN Controller properties

A deployed SD-WAN Controller has default properties. Each property regulates the Controller, for example, the controller.listen.port property specifies the TCP interface for incoming connections to which CPE devices connect.

Properties have change methods that determine whether the value of an individual property can be changed and at which time the change takes effect. A property can have the following change methods:

• Read-only — This property directly affects the operation of the SD-WAN Controller and cannot be changed.
• Reload — The property can be changed. When a property changes value, the orchestrator commits the new value to the database of the SD-WAN Controller. The new value takes effect after the Controller is restarted.

  A property value that is in the database, but has not yet taken effect is called a planning value. You can delete a planning value before restarting the SD-WAN Controller to keep the current value.

• Runtime — The property can be changed. The new value takes effect immediately.

You can modify properties with the Reload and Runtime change methods, reset them to default values, and delete planning values.

If your SD-WAN Controller is deployed as a multi-node cluster, you must change properties while configuring the whole cluster. You cannot change the properties of an SD-WAN Controller while configuring one of its nodes.

Editing or resetting SD-WAN Controller properties

Changes you make to SD-WAN Controller properties with the Runtime change method take effect immediately, while properties with the Reload method require Controller restart.

To change Controller properties or reset them to default values:

1. In the menu, go to the Infrastructure section.

   The SD-WAN infrastructure management page is displayed. By default, the Network resources tab is selected, which displays the table of SD-WAN Controllers.

2. Click Management next to the SD-WAN Controller and in the drop-down list, select Properties.

   The SD-WAN Controller properties page is displayed. By default, the All properties tab is selected, which displays a table of Controller properties.

3. Select the Changeable properties tab.

   A table of editable properties of the Controller is displayed.

4. If necessary, edit the value of an individual property:
   1. Click Management next to the property and in the drop-down list, select Edit.
   2. This opens a window; in that window, in the Planned value field, enter the new value of the property.
   3. Click Save.

   If you changed a property with a Runtime change method, the new value is displayed in the Current value column. The new value of a property with the Reload method is displayed in the Planned value column.

5. If necessary, reset an individual property to its default value:
   1. Click Management next to the property and in the drop-down list, select Reset property.
   2. In the confirmation window, click Reset.
6. If necessary, reset all properties to their default values:
   1. In the upper part of the page, click the settings button and in the drop-down list, select Reset all properties.
   2. In the confirmation window, click Reset.

Deleting an SD-WAN Controller property planning value

To cancel the change of an SD-WAN Controller property, you must delete the corresponding planning value. This action is applicable only to properties that have the Reload method.

To delete a planning value of an SD-WAN Controller property:

1. In the menu, go to the Infrastructure section.

   The SD-WAN infrastructure management page is displayed. By default, the Network resources tab is selected, which displays the table of SD-WAN Controllers.

2. Click Management next to the SD-WAN Controller and in the drop-down list, select Properties.

   The SD-WAN Controller properties page is displayed. By default, the All properties tab is selected, which displays a table of Controller properties.

3. Select the Changeable properties tab.

   A table of editable properties of the Controller is displayed.

4. If necessary, delete the planning value of an individual property:
   1. Click Management next to the property and in the drop-down list, select Delete planned value.
   2. In the confirmation window, click Delete.
5. If necessary, delete the planning values of all properties:
   1. In the upper part of the page, click the settings button and in the drop-down list, select Delete all planned values.
   2. In the confirmation window, click Delete.

An individual planning value or all planning values are deleted and are no longer displayed in the table.
