Creating a network interface without an IP address

To create a network interface without an IP address:

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 settings 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 settings 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 alias when creating an SD-WAN interface of the WAN type. Maximum length: 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. Maximum length: 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. If you want to create a bridge from physical or virtual interfaces whose names are specified in the Interface name field:
   1. Select the Bridge check box. This check box is cleared by default.
   2. If you want to use STP on the bridge to prevent routing loops, select the STP check box. This check box is cleared by default.
   3. In the Age (sec.) field, enter the duration in seconds for which dynamic records are stored in the MAC table of the bridge. If you want to use the bridge as a hub, enter 0 in this field. Range of values: 0 to 86,400.
7. If you want to enable the NetFlow protocol on the network interface, select the NetFlow check box. This check box is cleared by default.
8. In the Protocol drop-down list, select None.
9. If you want the network interface to be automatically enabled when the CPE device is enabled, select the Enable automatically check box. This check box is cleared by default.
10. If you want an IP address, route, and default gateway automatically assigned to the network interface, select the Force IP, route, and gateway check box. This check box is cleared by default.
11. In the Override MAC field, enter the MAC address of the network interface. The entered value replaces the actual MAC address of the network interface.
12. In the Override MTU field, enter the MTU for the network interface. The entered value overrides the default MTU.
13. Click Create.

    The network interface is created and displayed in the table.

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