Configuring the connection of a CPE device to the orchestrator and controller

When a CPE device is being registered, it connects to the orchestrator and controller. You can configure the connection in the CPE template. Orchestrator and controller connection settings specified in the CPE template are automatically propagated to all CPE devices that use this CPE template. Certain connection settings can also be configured on the CPE device, for example, you can enable automatic restart when the management session with the controller is terminated.

To configure the connection of a CPE device to the orchestrator and controller:

  1. Configure the connection in one of the following ways:
    • If you want to configure automatic connection to the orchestrator and controller in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the SD-WAN settings → General settings tab.
    • If you want to configure automatic connection to the orchestrator and controller in a CPE template, go to the SD-WAN → CPE menu section, click the CPE device, and select the SD-WAN settings → General settings tab and select the Override check box.

    This displays settings for connecting to the orchestrator and controller.

  2. If you are configuring a connection to the orchestrator and controller in a CPE template:
    1. In the Orchestrator IP/FQDN field, enter the IP address or FQDN of the orchestrator. Maximum length: 50 characters.
    2. In the Orchestrator protocol drop-down list, select the protocol for connecting the CPE device to the orchestrator:
      • http
      • https (default).
    3. In the Orchestrator port field, enter the port number of the orchestrator. Range of values: 0 to 65,535.
    4. In the OpenFlow transport drop-down list, select whether the management session between the CPE device and the controller is encrypted:
      • TCP for an unencrypted management session.
      • SSL for an encrypted management session. Default value.

    These settings can only be specified in the CPE template. The rest of the settings in these instructions can be configured both in the CPE template and on the CPE device.

  3. In the Auto-reboot drop-down list, select whether the CPE device is automatically restarted whenever the connection with the controller is lost:
    • Yes If you select this option, in the Reboot timeout (sec.) field, enter the time in seconds after which the CPE device is automatically restarted when connection with the controller is lost. Range of values: 60 to 2,073,600.
    • No (default).
  4. In the Prioritized control plane interface drop-down list, select how a new primary management session is determined between the CPE device and the controller when the previous session is terminated:
    • Random — a randomly selected session established form an SD-WAN interface of the WAN type becomes the new primary management session. Default value.
    • <SD-WAN interface> — the session established from the specified SD-WAN interface of the WAN type becomes the new primary management session. If the specified SD-WAN interface of the WAN type is not available, a session established from a randomly selected SD-WAN interface of the WAN type becomes the new primary management session.

      When this value is selected, if you want the previous primary management session to become the primary session again upon restoration:

      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 a restored management session becomes the primary session. Range of values: 0 to 86,400.
  5. In the Update interval (sec.) field, enter the period in seconds for sending REST API requests from the CPE device to the orchestrator. Range of values: 5 to 300. The default setting is 30.
  6. In the URL ZTP field, enter the URL template for the basic settings of the CPE device. When entering a template, consider the following limitations:
    • {config} is a mandatory part which is replaced with settings for the CPE device when a link is generated from the template.
    • Maximum length: 128 characters.
    • You must specify http or https.

    By default, the following URL template is used: http://192.168.7.1/cgi-bin/config?payload={config}.

  7. In the Interactive update interval (sec.) field, enter the period in seconds for sending REST API requests from the CPE device to the orchestrator in interactive mode. Range of values: 1 to 10. You can enable interactive mode for CPE device diagnostics.
  8. In the Interactive mode timeout (sec.) field, enter the time in seconds after which interactive mode is automatically disabled on the CPE device. Range of values: 30 to 180.
  9. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.
