• Creating a network interface for connecting to a wireless network on all devices that use the CPE template.

  To create a network interface for connecting to a wireless network 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 Network settings tab.

     The table of network interfaces is displayed.

  4. Click + Network interface.
  5. This opens a window; in that window, in the Alias field, enter an alias that you can reference when creating an SD-WAN interface. Maximum length: 15 characters. The default setting is eth1.

     Enter the value in the format: sdwan<interface number>. For example, if you are creating a network interface that the first SD-WAN interface will be mapped to, enter sdwan1.

  6. In the Protocol drop-down list, select QMI.
  7. In the QMI name field, enter the name of the modem used for connecting to the network. Maximum length: 30 characters. For example, you can enter /dev/cdc-wdm0.
  8. In the APN field, enter the APN ID of the service provider that issued the SIM card installed in the modem. Maximum length: 30 characters.
  9. In the Authentication type drop-down list, select which authentication is used on the network interface:
     • PAP (Password Authentication Protocol). The client sends credentials to the authentication server as plain text. The server searches its database for the received credentials and, if a match is found, grants access to the client.
     • CHAP (Challenge-Handshake Authentication Protocol). The client receives a random string from the authentication server, combines it with the password and applies a one-way hash function to the combination to generate a response. The server receives the response, performs the same operations and, if the generated responses match, grants access to the client.
     • PAP and CHAPmeans that both types of authentication are used on the network interface.
     • Nonemeans that authentication is not used on the network interface.
  10. In the Login for PAP/CHAP authentication field, enter the user name for PAP/CHAP authentication. Maximum length: 30 characters. If you do not want to use authentication, do not specify a value for this setting.
  11. In the Password for PAP/CHAP authentication field, enter the password for PAP/CHAP authentication. Maximum length: 30 characters. If you do not want to use authentication, do not specify a value for this setting.
  12. In the PIN code field, enter the PIN code of the SIM card installed in the modem. Maximum length: 4 digits.

      In the Delay field, enter the length of time (in seconds) that must elapse before communication between the network interface and the modem starts. Maximum value: 30. This setting is used when the modem takes too long to start.

  13. If necessary, add the network mode that you want to use on the network interface:
      1. Under Modes, click + Add.
      2. In the drop-down list, select one of the following values:
         • All (use all available network modes).
         • LTE.
         • UMTS.
         • GSM.
         • CDMA.
         • TD-SCDMA.

      You can add multiple modes.

  14. In the Connection profile field, enter the connection profile index that the network interface must use instead of the APN ID. Maximum length: 30 characters.
  15. In the IP stack drop-down list, select which IP stack is used on the network interface:
      • IPv4 to use the IPv4 protocol stack on the network interface. This is the default setting.
      • IPV6 to use the IPv6 protocol stack on the network interface.
      • Dual stack (IPv4 and IPv6) to use IPv4 and IPv6 dual stack on the network interface.
  16. Select the IPv4 over DHCP check box to assign an IPv4 address to the network interface via DHCP. To select this check box simultaneously with the IPv6 over DHCP check box, select Dual stack (IPv4 and IPv6) (for dual stack) in the IP stack drop-down list. This check box is selected by default.
