Configure a Device as an TFTP Client

Network Requirements

• A PC acts as a TFTP server, and Device acts as a TFTP client. The network between the server and the device is normal. The files to be downloaded are placed in the TFTP server directory.
• The device acts as the TFTP client to upload files to and download files from the TFTP server.

Step 3: Enable the TFTP server function on PC, and place the files to be downloaded in the TFTP server directory. (Omitted)

Step 4: Device acts as the TFTP client to upload files to and download files from the TFTP server.

#On Device, copy a file from the TFTP server to the file system of Device.

#On Device, copy the startup file from Device to the TFTP server.

  If the "Downloading####OK!" message is printed, it indicates that the file copy is successful. The message shows the file size, which is determined by the actual file size.
• When you use a device to copy a file, if the " Failed! ErrorNum: 0x41, ErrorType: Host unreach." message is printed, the cause may be that the TFTP server function is not enabled, or the route between the server and the client is not reachable.
