Downloading an Image File by Using TFTP

For the download and upload algorithms to operate properly, do not rename image directories.

server and overwrite the existing image.

Step 2

Before uploading the image file, you might need to create an empty file on the TFTP server. To
create an empty file, enter the touch filename command, where filename is the name of the file you
will use when uploading the image to the server.
During upload operations, if you are overwriting an existing file (including an empty file, if you had
to create one) on the server, ensure that the permissions on the file are set correctly. Permissions on
the file should be world-write.
Purpose
Copy the image to the appropriate TFTP directory on the
workstation. Make sure the TFTP server is properly configured; see
the
"Preparing to Download or Upload an Image File by Using
TFTP" section on page 17-20

Download the image file from the TFTP server to the bridge, and
overwrite the current image.
