Command
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.
If you specify the /leave-old-sw, the existing files are not removed. If there is not enough space to install
the new image and keep the current running image, the download process stops, and an error message is
displayed.
The algorithm installs the downloaded image on the system board flash device (flash:). The image is
placed into a new directory named with the software version string, and the BOOT environment variable
is updated to point to the newly installed image.
If you kept the old image during the download process (you specified the /leave-old-sw keyword), you
can remove it by entering the delete /force /recursive filesystem:/file-url privileged EXEC command.
For filesystem, use flash: for the system board flash device. For file-url, enter the directory name of the
old image. All the files in the directory and the directory are removed.
Caution
For the download and upload algorithms to operate properly, do not rename image names.

Working with the Cisco IOS File System, Configuration Files, and Software Images
Purpose
Download the image file from the TFTP server to the switch, and
overwrite the current image.
•
The /overwrite option overwrites the software image in flash
memory with the downloaded image.
•
The /reload option reloads the system after downloading the
image unless the configuration has been changed and not been
saved.
For //location, specify the IP address of the TFTP server.
•
For /directory/image-name.tar, specify the directory
•
(optional) and the image to download. Directory and image
names are case sensitive.
Download the image file from the TFTP server to the switch, and
keep the current image.
The /leave-old-sw option keeps the old software version after
•
a download.
The /reload option reloads the system after downloading the
•
image unless the configuration has been changed and not been
saved.
For //location, specify the IP address of the TFTP server.
•
For /directory/image-name.tar, specify the directory
•
(optional) and the image to download. Directory and image
names are case sensitive.
