stands for Trivial File Transfer Protocol and is a mechanism to tranfer files from one device to another. It is typically used by the network administrator to copy configuration files, log files and firmware to/from networking devices. TFTP uses the UDP protocol over port 69.

The Quantellium TFTP server only supports “Octet mode” transfers!

“Octet mode” allows for the transfer of arbitrary raw 8-bit bytes, with the received file resulting byte-per-byte identical to the one sent. This is of eminent importance when booting a device or when updating firmware!

Operation modes

The TFTP server is enabled by default and can be managed on the Various system settings page (Log on with Administrator rights and select Administration | Various system setting from the main menu on the left). There are three modes of operation:

1) Read only

In this mode, firmware or config files should be placed in the directory:


Of course only read operations are allowed. Reads (and also Write attemps) are logged to the Logged events list.

2) Read/Write, same folder, overwrite allowed

In this mode, files should also be placed in the directory:


but besides reading also writing is allowed! Existing files are overwritten by Write operations to the same file name! All access is logged to the Logged events list.

3) Read/Write, separate folders, no overwrite

This mode also allows reading and writing but from/to different folders. Reading is allowed only from the


folder and writing only to the


folder. A “Write” attempt with a file name that already exists is not allowed in this mode! All access is logged to the Logged events list.
