Working with Software Images
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 system boot path 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.

Uploading an Image File by Using TFTP

You can upload an image from the access point to a TFTP server. You can later download this image to
the access point or to another access point of the same type.
Caution For the download and upload algorithms to operate properly, do not rename image directories.
Beginning in privileged EXEC mode, follow these steps to upload an image to a TFTP server:
The archive upload-sw privileged EXEC command builds an image file on the server by uploading these
files in order: info, the Cisco IOS image, the HTML files, and info.ver. After these files are uploaded,
the upload algorithm creates the tar file format.
Copying Image Files by Using FTP
You can download an access point image from an FTP server or upload the image from the access point
to an FTP server.
Command Purpose
Step1 Make sure the TFTP server is properly configured; see the
“Preparing to Download or Upload an Image File by Using TFTP”
section on page 20-20.
Step1 Log into the access point through a Telnet session.
Step2 archive upload-sw
tftp:[[//location]/directory]/image-name.tar
Upload the currently running access point image to the TFTP
server.
•For //location, specify the IP address of the TFTP server.
•For /directory/image-name.tar, specify the directory (optional)
and the name of the software image to be uploaded. Directory
and image names are case sensitive. The image-name.tar is the
name of the software image to be stored on the server.
