Configuring TFTP

Trivial File Transfer Protocol (TFTP) is a simplified version of FTP for file transfer over secure reliable
networks. TFTP uses UDP port 69 for connection establishment and data transmission. In contrast
to TCP-based FTP, TFTP requires no authentication or complex message exchanges, and is easier
to deploy.
TFTP supports the following transfer modes:
Binary mode—Used to transfer image files, such as .bin .btm files.
•
ASCII mode—Used to transfer text files, such as .txt, .bat, and .cfg files.
•
The device can operate only as a TFTP client (see
Figure 29 TFTP application scenario

FIPS compliance

The device supports the FIPS mode that complies with NIST FIPS 140-2 requirements. Support for
features, commands, and parameters might differ in FIPS mode and non-FIPS mode. For more
information about FIPS mode, see Security Configuration Guide.
TFTP is not supported in FIPS mode.

Prerequisites

Run a TFTP server program on the file host and set a TFTP working directory.
Configure IP addresses and routes to make sure the device and the TFTP server can reach each
other.

Using the device as a TFTP client

The device provides the following modes for downloading a new file from a TFTP server:
Normal download—The new file is written directly to Flash and overwrites the old file that has
•
the same name as it. If file download is interrupted, both old and new files are lost.
Secure download—The new file is downloaded to memory and will not be written to Flash until
•
the whole file is obtained. A download failure does not affect the old file that has the same name
as the old file.
To avoid undesired file loss, use the secure download mode. If you use the normal download mode
because of insufficient memory, assign the new file a file name unique in Flash.
You can use the tftp client source command to specify a source IP address or source interface for the
TFTP packets sent by the device. If a source interface (typically, a loopback interface) is specified, its
primary IP address is used as the source IP address for the TFTP packets. The source interface
setting and the source IP address setting overwrite each other.
