Copying Image Files By Using TFTP
You can download a switch image from a TFTP server or upload the image from the switch to a TFTP
server.
You download a switch image file from a server to upgrade the switch software. You can overwrite the
current image with the new one or keep the current image after a download.
You upload a switch image file to a server for backup purposes; this uploaded image can be used for
future downloads to the same or another switch of the same type.
Note Instead of using the copy privileged EXEC command or the archive tar privileged EXEC command, we
recommend using the archive download-sw and archive upload-sw privileged EXEC commands to
download and upload software image files.
