Working with Software Images
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 spec ify 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 thes e 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 running image, the download process stops, a nd an er ror m essage is
displayed.
The algorithm installs the downloaded image onto the system board flash device (flash:). The imag e is
placed into a new directory named with the software versio n strin g, and the B OO T en vi ronmen t v ariable
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 software image. All the files in the directory and the direc tor y are removed.
Caution For the download and upload algorithms to operate properly, do not rename image names.
Step8 archive download-sw /leave-old-sw /reload
ftp:[[//username[:password]@location]/directory]
/image-name.tar
Download the image file from the FTP 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 //username[:password], specify the username and
password. These must be associated with an account on
the FTP server. For more information, see the “Preparing
to Download or Upload an Image File By Using FTP”
section on page B-24.
•For @location, specify the IP address of the FTP server.
•For directory/image-name.tar, specify the directory
(optional) and the image to download. Directory and
image names are case sensitive.
