Working with SD-WAN instances

The table of SD-WAN instances is displayed in the SD-WAN → SD-WAN instances section. Information about SD-WAN instances is displayed in the following table columns:

• ID is the ID of the SD-WAN instance.
• Tenant is the tenant for which the SD-WAN instance is deployed.
• Status is the status of the SD-WAN instance:
  • Ok means the SD-WAN instance is operating normally.
  • Controller is absent means the SD-WAN instance does not have a controller.
  • Error means an error occurred during the operation of the SD-WAN instance.
  • Deleting means the SD-WAN instance is in the process of being deleted.
  • Deleted means the SD-WAN instance was deleted.
• # of CPEs is the number of CPE devices that have been added to the SD-WAN instance.
• Controllers are IP addresses and port numbers of controllers of the SD-WAN instance.
• DC is the data center in which SD-WAN instance is deployed.
• VIM is the VIM of the SD-WAN instance.
• Created is the date and time when the SD-WAN instance was deployed.

The actions that you can perform with the table are described in the Managing solution component tables instructions.

The SD-WAN instance settings are displayed on the following tabs:

• Configuration contains basic information about the SD-WAN instance.
• Monitoring contains SD-WAN instance monitoring results.
• Service requests contains service requests of the SD-WAN instance.
• Tenant self-service contains tenants that have been added to the SD-WAN instance.

Configuring controller nodes of an SD-WAN instance

When configuring controller nodes of the SD-WAN instance, you can change their IP addresses and TCP port numbers. This automatically changes the IP addresses and TCP port numbers of controller nodes on all CPE devices that are added to the SD-WAN instance. If SD-WAN interfaces of the WAN type of the CPE device are connected to different networks, for example, the internet and a private MPLS network, you can change the IP addresses and TCP port numbers of controller nodes on individual SD-WAN interfaces of the WAN type when you create or edit SD-WAN interfaces of the WAN type. The IP addresses and TCP port numbers specified on the SD-WAN interface of the WAN type take precedence over the IP addresses and TCP port numbers specified when configuring the controller nodes of the SD-WAN instance.

If you deployed multiple controller nodes when you deployed the SD-WAN instance, you can specify which controller node is the arbiter node while configuring the controller nodes of the SD-WAN instance. When an arbiter node is specified in the orchestrator web interface, CPE devices do not establish management sessions with that controller node, which reduces the load on the CPE devices.

After configuring the controller nodes of the SD-WAN instance, to apply the changes, you must restart the CPE devices that already have been registered.

To configure controller nodes of an SD-WAN instance:

1. In the menu, go to the SD-WAN → SD-WAN instances section.

   A table of SD-WAN instances is displayed.

2. Click the SD-WAN instance whose controller nodes you want to configure.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, which displays general information about the SD-WAN instance.

3. If necessary, do one of the following:
   • If you want to change the IP address of a controller node, in the IP address field, enter an IPv4 address. The number of fields corresponds to the number of controller nodes.
   • If you want to change the TCP port number of a controller node, in the Port field, enter the number of the base port. Range of values: 1 to 65,535. Default value: 6653. The number of fields corresponds to the number of controller nodes.

     Along with the base port of the controller node, ports with the next three consecutive numbers are automatically specified. For example, if you enter the 6653 as the base port number, ports 6654, 6655, and 6656 are automatically specified.

   • If you want to specify an arbiter node, select the Arbiter check box next to the controller node. You cannot specify an arbiter node if you deployed only one controller node while deploying the SD-WAN instance.
4. In the upper part of the settings area, click Save to save the settings of the SD-WAN instance.

Viewing the usage of an SD-WAN instance

You can see which CPE devices have been added to the SD-WAN instance.

To view the usage of an SD-WAN instance:

1. In the menu, go to the SD-WAN → SD-WAN instances section.

   A table of SD-WAN instances is displayed.

2. Click the SD-WAN instance for which you want to view its usage.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, which displays general information about the SD-WAN instance.

3. In the upper part of the settings area, under Actions, click Show associated CPEs.

This opens the CPE section which displays a table of CPE devices added to the SD-WAN instance.

Viewing the topology of an SD-WAN instance

To view the topology of an SD-WAN instance:

1. Log in to the self-service portal of the tenant for which the SD-WAN instance is deployed.
2. In the menu, go to the Infrastructure section.

   This opens the resource management page. By default, the Network resources tab is selected, which displays the table of controllers.

3. Click Management → Configuration menu next to the controller.
4. Go to the Topology section.

   The topology of the SD-WAN instance is displayed.

5. If necessary, select the following check boxes:
   • Select the Tunnel utilization check box to display the utilization of the links. The utilization level of the link is represented by the following colors:
     • Green — Low link utilization.
     • Yellow — Medium link utilization.
     • Red — High link utilization.
   • Select the Segments check box and in the Segment switches drop-down list, select two CPE devices to display all links between those devices.
   • Select the Name check box to display the names of CPE devices.
   • Select the IP address check box to display the IP addresses of CPE devices.

   By default, all check boxes are cleared.

Adding a tenant to an SD-WAN instance

If you want to use the controller of a single SD-WAN instance for multiple tenants, you need to add tenants to that SD-WAN instance. Using a single SD-WAN instance controller for multiple tenants eliminates the need to deploy a separate SD-WAN instance for each tenant.

To add a tenant to an SD-WAN instance:

1. In the menu, go to the SD-WAN → SD-WAN instances section.

   A table of SD-WAN instances is displayed.

2. Click the SD-WAN instance into which you want to add a tenant.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, which displays general information about the SD-WAN instance.

3. Select the Tenant self-service tab.

   A table of tenants is displayed.

4. Click + Add.
5. This opens a window; in that window, select the created tenant that you want to add to the SD-WAN instance.
6. In the Maximum CPEs field, enter the maximum number of CPE devices available to the tenant.
7. Click Add.

The tenant is added to the SD-WAN instance and is displayed in the table.

Removing a tenant from an SD-WAN instance

You can remove a tenant that has been added to an SD-WAN instance to prevent the tenant from using the controller of that SD-WAN instance.

To remove a tenant from an SD-WAN instance:

1. In the menu, go to the SD-WAN → SD-WAN instances section.

   A table of SD-WAN instances is displayed.

2. Click the SD-WAN instance from which you want to remove a tenant.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, which displays general information about the SD-WAN instance.

3. Select the Tenant self-service tab.

   A table of tenants is displayed.

4. Click Delete next to the tenant that you want to remove from the SD-WAN instance.
5. In the confirmation window, click Delete.

The tenant is deleted from the SD-WAN instance and is no longer displayed in the table.

Deleting an SD-WAN instance

When you delete an SD-WAN instance, the CPE devices that have been added to it and the SD-WAN network service deployed for the SD-WAN instance are also automatically deleted. However, the tenant for which the SD-WAN instance is deployed is not deleted. An alternative way of deleting an SD-WAN instance is to delete the SD-WAN network service.

Deleted SD-WAN instances cannot be restored.

To delete an SD-WAN instance:

1. In the menu, go to the SD-WAN → SD-WAN instances section.

   A table of SD-WAN instances is displayed.

2. Click the SD-WAN instance that you want to delete.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Configuration tab is selected, which displays general information about the SD-WAN instance.

3. In the upper part of the settings area, under Actions, click Delete.
4. In the confirmation window, click Delete.

The SD-WAN instance is deleted and is no longer displayed in the table.
