Creating a network interface for connecting to a PPPoE server

To create a network interface for connecting to a PPPoE server:

  1. Create a network interface in one of the following ways:
    • If you want to create a network interface in a CPE template, go to the SD-WAN → CPE templates section, click the CPE template, and select the Network tab.
    • If you want to create a network interface on a CPE device, go to the SD-WAN → CPE section, click the CPE device, and select the Network tab.

    The table of network interfaces is displayed.

  2. Click + Network interface.
  3. This opens a window; in that window, in the Alias field, enter the name of the network interface for mapping the network interface to an OpenFlow port. You must specify this network interface name when creating an SD-WAN interface of the WAN type. The maximum length of the name is 15 characters.
  4. If you want to add a network interface to a firewall zone, in the Zone drop-down list, select the created firewall zone.
  5. In the Interface name field, enter the name of the physical port or virtual interface of the operating system of the CPE device. The maximum length of the name is 256 characters. For example, you can enter eth0, eth1, eth2, or tun0. To create a bridge from multiple interfaces, enter their names separated by spaces.

    If you want to assign an outer VLAN tag to a network interface, enter a period (.) after the physical port or virtual interface name of the operating system, and then enter the outer VLAN tag. For example, you can enter eth2.150.

  6. In the Protocol drop-down list, select PPPoE.
  7. In the Access concentrator field, enter the IP address or host name of the access concentrator to which the network interface connects. The maximum length of the host name is 50 characters. If you do not enter a value in this field, the Point-to-Point Protocol Daemon (PPPD) uses the first access concentrator it detects.
  8. In the Service field, enter the name of the PPPoE service to which the network interface connects. The maximum length of the name is 30 characters. If you do not enter a value in this field, PPPD uses the first PPPoE service it detects.
  9. In the Authentication type drop-down list, select which authentication is used on the network interface:
    • PAP and CHAP if PAP and CHAP authentication is used on the network interface. If you select this option, do the following:
      1. In the Username for PAP/CHAP authentication field, enter the user name for PAP/CHAP authentication. The maximum length of the name is 30 characters.
      2. In the Password for PAP/CHAP authentication field, enter the password for PAP/CHAP authentication. Maximum length of the password: 30 characters.
    • Nonemeans that authentication is not used on the network interface.
  10. In the Failed pings maximum field, enter the number of unsuccessful ICMP requests before the network interface considers the PPPoE server unavailable. Range of values: 1 to 3600. Default value: 5.
  11. In the Ping interval (sec.) field, enter the interval in seconds that the network interface must wait for before sending ICMP requests to the PPPoE server. Range of values: 1 to 3600. Default value: 1.
  12. If you want the network interface to terminate an inactive PPPoE connection after the specified time, in the Timeout (sec.) field, enter the time in seconds. Range of values: 1 to 3600.
  13. If necessary, in the Host-Uniq field, enter the Host-Uniq tag for the PPPoE connection. The maximum length of the tag is 30 characters. If you do not enter a value in this field, the value of the Host-Uniq tag is the same as the PPPD process identifier.
  14. In the Override MTU field, enter the MTU for the network interface. The entered value overrides the default MTU.
  15. In the Route metric field, enter the default route metric for the network interface. The CPE device uses the default route with the lowest metric. For example, you can specify the following default route metrics for network interfaces:
    • 100 for network interface sdwan0
    • 101 for network interface sdwan1
    • 102 for network interface sdwan2

    In this case, the CPE device uses the default route of the sdwan0 network interface. If the sdwan0 network interface fails, the default route of the sdwan1 network interface is used next, followed by the default route of the sdwan2 network interface.

  16. If necessary, clear the following check boxes:
    • Clear the Keepalive adaptive check box if you want the network interface that has not received Link Control Protocol (LCP) control packets from the PPPoE server to terminate the PPPoE connection, even if traffic has arrived from the PPPoE server.
    • Clear the Use default route check box if you do not want to use the route obtained from the PPPoE server as the default route on the network interface.
    • Clear the Peer-assigned DNS server check box if you do not want the network interface to use DNS servers assigned to its neighbors.

    By default, the check boxes are selected.

  17. If you want to pass additional command line arguments when starting PPPD (Point-to-Point Protocol Daemon), in the PPPD field, enter the command line arguments. For example, you can pass authentication parameters, IP addresses, and scripts to PPPD.
  18. If necessary, specify a DNS server for the network interface:
    1. Under DNS servers, click + Add.
    2. In the field that is displayed, enter the IP address of the DNS server.

    The DNS server is specified and displayed in the DNS servers section. You can specify multiple DNS servers or delete a DNS server. To delete a DNS server, click the delete icon cross_icon_3 next to it.

  19. Click Create.

    The network interface is created and displayed in the table.

  20. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.
