Managing network interfaces

Network interfaces correspond to physical ports and virtual interfaces of the CPE device's operating system that connect to the WAN or the LAN. You must map the network interfaces of the CPE device to the OpenFlow ports of the virtual switch using SD-WAN interfaces.

The table of network interfaces is displayed in the CPE template and on the device:

• To display the table of network interfaces in a CPE template, go to the SD-WAN → CPE templates menu section, click the template and in the displayed settings area, select the Network settings tab.
• To display the table of network interfaces on a CPE device, go to the SD-WAN → CPE menu section, click the device, and in the displayed settings area, select the Network settings tab.

Information about network interfaces is displayed in the following columns of the table:

• Alias is the name of the network interface for mapping the network interface to an OpenFlow port. You specify this name when creating an SD-WAN interface of the WAN type.
• Inherited specifies whether the network interface is inherited from the CPE template:
  • Yes
  • No

  This column is displayed only on the CPE device.

• Interface name is the name of the physical port or virtual interface of the operating system of the CPE device.
• Protocol is the method of assigning an IP address to the network interface:
  • DHCP client means the IP address is automatically assigned by DHCP.
  • Static IPv4 address means an IPv4 address is statically assigned.
  • Static IPv6 address means an IPv6 address is statically assigned.
  • QMI means LTE network connection settings are specified manually.
  • PPPoE means the PPPoE server connection settings are specified manually.
  • None means an IP address is not assigned.
• IP/mask are the IP address, mask, and default gateway of the network interface.
• Enable automatically specifies whether the network interface must be automatically enabled when the CPE device is powered on:
  • Yes
  • No
