Downloading an Image File By Using TFTP

You can download a new image file and replace the current image or keep the current image.
Beginning in privileged EXEC mode, follow Steps 1 through 3 to download a new image from a TFTP
server and overwrite the existing image. To keep the current image, perform Steps 1 and 2 and Step 4.
Command
Step 1
Step 2
Step 3
archive download-sw /overwrite /reload
tftp:[[//location]/directory]/image-name.tar
Step 4
archive download-sw /leave-old-sw /reload
tftp:[[//location]/directory]/image-name.tar
The download algorithm verifies that the image is appropriate for the switch model and that enough
DRAM is present, or it aborts the process and reports an error. If you specify the /overwrite option, the
download algorithm removes the existing image on the flash device whether or not it is the same as the
new one, downloads the new image, and then reloads the software.
Note If the flash device has sufficient space to hold two images and you want to overwrite one of these images
with the same version, you must specify the /overwrite option.
