Chapter20 Managing Firmware and Configurations

Working with Software Images

Note To avoid an unsuccessful download, use the archive download-sw /safe command, which downloads

the image first and does not delete the current running version until the download succeeds.

The download algorithm verifies that the image is appropriate for the access point 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 The procedure to downgrade an access point IOS is the same procedure for performing an IOS upgrade.

To downgrade an access point IOS, enter archive download-sw /overwrite /reload

tftp:[[//location]/directory]/image-name. The /overwrite parameter erases the current IOS image, and

the new downgraded version of IOS is loaded onto the access point. The /reload option reloads the

system after downloading the image unless the configuration has been changed and not saved.

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.

Step3 archive download-sw /overwrite /reload

tftp:[[//location]/directory]/image-name

Download the image file from the TFTP server to the access point,

and overwrite the current image.

•The /overwrite option overwrites the software image in Flash

with the downloaded image.

•The /reload option reloads the system after downloading the

image unless the configuration has been changed and not

saved.

•For //location, specify the IP address of the TFTP server.

•For /directory/image-name, specify the directory (optional)

and the image to download. Directory and image names are

case sensitive.

Step4 archive download-sw /leave-old-sw /reload

tftp:[[//location]/directory]/image-name

Download the image file from the TFTP server to the access point,

and keep the current image.

•The /leave-old-sw option keeps the old software version after

a download.
