Adding, editing, and deleting interfaces

Interfaces are displayed in a table on the node details page.

Adding an interface

To add an interface, click the add button next to the header on the Interfaces table. This will open the Add interface modal. From here you can specify the following information. Fields marked with an asterisk are required.

Name *

The name of the interface. This must match the interface name on the device, such as eth0 or enp2s0.

Aliases

Any alternative names you would like to assign to the interface (aka “altnames”).

VRF

The VRF assigned to this interface. Traffic entering this interface will enter this VRF. If the interface is defined without a VRF, this interface will only be used for establishing SD-WAN tunnels and not for client traffic.

DHCP

Enabled

Whether or not DHCP is enabled on this interface.

Keep on shutdown

When toggled on, any DHCP addresses assigned to this interface will persist even if the SD-WAN service is shutdown. This allows the node to maintain network connectivity regardless of whether SD-WAN is running.

Addresses

Any static addresses you would like to assign to this interface. The following values are supported:

Address *

A CIDR-formatted static address.

Peer address

An optional CIDR-formatted address indicating the address on the peer remote that will be used to reach the remote. Most configurations can omit this field, as it is only used in rare configurations.

Gateway address

An optional host address indicating the gateway for the static address. If a gateway is defined and there is no VRF on the interface, a default route to the gateway will be created in a private, non-VRF routing table. If there is a VRF on the interface, the default route will be in the VRF’s routing table.

Keep on shutdown

When toggled on, this address will persist even if the SD-WAN service is shut down. This allows the node to maintain network connectivity regardless of whether the SD-WAN service is running.

DNS servers

Any upstream DNS servers needed for DNS resolution on the interface. If not given, a list of public DNS servers will be used.

Editing an interface

To edit an interface, click the edit button in the Actions column of the corresponding row in the Interfaces table. This will open the Edit interface modal.

Deleting an interface

To delete an interface, click the delete button in the Actions column. This will ask you to confirm before the interface is permanently deleted.
