Configuring the connection of a CPE device to the SD-WAN network

The CPE device connects to the SD-WAN network to interact with the

. You can configure the SD-WAN network connection on an individual CPE device or on all devices that use the CPE template.

To configure the SD-WAN network connection, use the following instructions:

Configuring the SD-WAN network connection on an individual CPE device.
When configuring the SD-WAN network connection on an individual CPE device, you cannot specify the following settings:
- IP address or FQDN of the orchestrator
- Protocol for connecting the device to the orchestrator
- Port number of the orchestrator
- Protocol for establishing an OpenFlow connection between the device and the SD-WAN Controller
To configure the SD-WAN network connection on an individual CPE device:
1. In the menu, go to the SD-WAN section.
  By default, the CPE subsection is displayed with a table of CPE devices.
2. Click the CPE device.
  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 button .
3. Select the SD-WAN settings tab.
  By default, the General settings tab is selected, which displays the SD-WAN network connection settings.
4. Select the Override check box to ignore the applied CPE template and make the settings in the selected tab editable. This check box is cleared by default.
5. In the Auto-reboot drop-down list, select whether you want to restart the CPE device whenever the connection with the SD-WAN Controller is lost.
  - Yes
  - No (selected by default)
6. If in the Auto-reboot drop-down list, you selected Yes, in the Reboot timeout (sec.) field, enter the time in seconds after which the CPE device must reboot if communication with the SD-WAN Controller is lost. Range of values: 60 to 2,073,600.
7. In the Prioritized control plane interface drop-down list, select how the primary session is switched to ensure interaction between the CPE device with SD-WAN Controllers:
  - Random to have a new session selected randomly. This is the default setting.
  - <SD-WAN interface> to pick the session established from the specified SD-WAN interface as the new session. If that session is unavailable, the primary session is selected at random from the remaining active sessions.
8. If in the Prioritized control plane interface drop-down list, you selected <SD-WAN interface>, if necessary, configure switching back to the previous session when it is restored:
  1. Select the Preemption check box. This check box is cleared by default.
  2. In the Timeout field, enter the time in seconds after which the session must be switched. Range of values: 0 to 86,400. If the check box is cleared, switching back to the previous primary session does not happen.
9. In the Update interval (sec.) enter the interval in seconds for sending API requests from the CPE device to the orchestrator. These requests are used to receive configuration changes. Range of values: 5 to 300. The default setting is 30.
10. In the URL ZTP field, enter a web address template for activating the CPE device using a web address. Consider the following when entering a web address template:
  - {config} is a mandatory part which is replaced with settings for the specific CPE device when a link is generated from the template.
  - Maximum length: 128 characters.
  - Make sure to specify http or https.
  By default, the following web address template is used: http://192.168.7.1/cgi-bin/luci/config?payload={config}.
11. In the upper part of the settings area, click Save to save the configuration of the CPE device.
Configuring the SD-WAN network connection on all devices that use the CPE template.
To configure the SD-WAN network connection on all devices that use the CPE template:
1. In the menu, go to the SD-WAN → CPE templates subsection.
  A table of CPE templates is displayed.
2. Click the CPE template.
  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 button .
3. Select the SD-WAN settings tab.
  By default, the General settings tab is selected, which displays the SD-WAN network connection settings.
4. In the Orchestrator IP/FQDN field, enter the IP address or FQDN of the orchestrator. Maximum length: 50 characters.
5. In the Orchestrator protocol drop-down list, select the protocol for connecting the CPE device to the orchestrator:
  - http
  - https (selected by default)
6. In the Orchestrator port field, enter the port number of the orchestrator. Range of values: 0 to 65,535.
7. In the OpenFlow transport drop-down list, select the protocol for establishing an OpenFlow connection between the CPE device and the SD-WAN Controller.
  - TCP
  - SSL (selected by default)
8. In the Auto-reboot drop-down list, select whether you want to restart the CPE device whenever the connection with the SD-WAN Controller is lost.
  - Yes
  - No (selected by default)
9. If in the Auto-reboot drop-down list, you selected Yes, in the Reboot timeout (sec.) field, enter the time in seconds after which the CPE device must reboot if communication with the SD-WAN Controller is lost. Range of values: 60 to 2,073,600.

  - Random to have a new session selected randomly. This is the default setting.
  - <SD-WAN interface> to pick the session established from the specified SD-WAN interface as the new session. If that session is unavailable, the primary session is selected at random from the remaining active sessions.
11. If in the Prioritized control plane interface drop-down list, you selected <SD-WAN interface>, if necessary, configure switching back to the previous session when it is restored:
  1. Select the Preemption check box. This check box is cleared by default.
  2. In the Timeout field, enter the time in seconds after which the session must be switched. Range of values: 0 to 86,400. If the check box is cleared, switching back to the previous primary session does not happen.
