Configuring the TFTP client

When a device acts as a TFTP client, you can upload a file on the device to a TFTP server or download
a file from the TFTP server to the local device. You can use either of the following methods to download
a file:
• Normal download: The device writes the obtained file to the storage medium directly. If you
download a remote file using a filename destination-filename that exists in the target directory, the
device deletes the original file and saves the new one. If file download fails due to network
disconnection or other reasons, the original file will never recover because it has been deleted.
Secure download: The device saves the obtained file to its memory and does not write it to the
•
storage medium until the whole file is obtained. If you download a remote file using a filename
destination-filename that exists in the target directory, the original file is not overwritten. If file
download fails due to network disconnection or other reasons, the original file still exists. This mode
is more secure but consumes more memory.
H3C recommends that you use the secure mode or, if you use the normal mode, specify a filename that
does not exist in the target directory.
When using the tftp client source or tftp command, you can specify the source interface (such as a
loopback) or source IP address. The primary IP address of the specified source interface or the specified
source IP address is used as the source IP address of sent TFTP packets.
The TFTP client follows these rules to select the source IP address of packets sent to the TFTP server:
If no source IP address is specified, the IP address of the output interface of the route to the server
•
is used as the source IP address.
• The source IP address specified with the tftp client source or tftp command is used.
If you first use the tftp client source command to specify a source IP address and then use the tftp
•
command to specify another source IP address, the latter is used.
The source IP address specified with the tftp client source command applies to all TFTP connections
•
while the one specified with the tftp command applies to the current TFTP connection only.
Follow these steps to configure the TFTP client:
