Working with the Cisco IOS File System, Configuration Files, and Software Images
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 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 running image, the download process stops, and an error message is displayed.
The algorithm installs the downloaded image onto 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.
6. end Returns to privileged EXEC mode.
7. archive download-sw /overwrite /reload
ftp:[[//username[:password]@location]/directory]/i
mage-name.tar
Downloads the image file from the FTP 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 //username[:password], specify the username and
password; these must be associated with an account on
the FTP server.
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.
8. archive download-sw /leave-old-sw /reload
ftp:[[//username[:password]@location]/directory]/i
mage-name.tar
Downloads 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 @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.
