Configuring a default node or reconfiguring an existing node via USB key

Any node with a default configuration can be assigned a node key using the web service or via USB key. Furthermore, USB key configuration can also be used to reconfigure existing nodes. This is especially useful in the following situations:

  1. A bad configuration was sent to the node and it is unable to connect to the internet to get an updated configuration.

  2. A previously-deployed and decommissioned node needs to be repurposed as a new node.

The following guide applies equally in the case of configuring a default node, or when reconfiguring an existing node.

Note

To set up a device as a default node, refer to the node ISO installation or existing Linux installation documentation.

Downloading the configuration

On the management server web interface, locate and click on the Download config button on the node’s details page:

configuring-a-default-node-or-reconfiguring-an-existing-node-via-usb-key-1

This will download the configuration as a binary-formatted file. Config file names are formatted as follows:

sdwan-<node_id>-<revision_number>.config

Next, copy or move the file onto the root directory of a USB key. Ensure that the file is not in a subdirectory, as this will prevent the node software from locating it. Once the file has been copied, you can eject the device.

Connecting to the internet

To configure a default node via USB key, you must first ensure that the node has internet access. Any Ethernet interface on the device that is connected to a DHCP network will work for this purpose.

Configuring the node

From here, simply insert the USB key into a port on the node’s hardware. The running instance of SD-WAN software will automatically detect the configuration file on the USB key and load it. Make sure to leave the USB key plugged in until you see the node come online on the management server interface.
