Working with Software Images

•During upload operations, if you are overwriting an existing file (including an empty file, if you had

to create one) on the server, ensure that the permissions on the file are set correctly. Permissions on

the file should be world-write.

Downloading an Image File by Using TFTP

You can download a new image file and replace the current image or keep the current image.

Caution For the download and upload algorithms to operate properly, do not rename image directories.

Beginning in privileged EXEC mode, follow Steps 1 through 3 to download a new image from a TFTP

server and overwrite the existing image.

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.

Command Purpose

Step1 . Copy the image to the appropriate TFTP directory on the

workstation. 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

Step2 Log into the access point through a Telnet session.

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.
