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 room to install
the new image an 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.
If you kept the old software 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 directory are removed.
Uploading an Image File by Using RCP
You can upload an image from the access point to an RCP server. You can later download this image to
the same 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.
The upload feature is available only if the HTML pages associated with the Cluster Management Suite
(CMS) have been installed with the existing image.
Beginning in privileged EXEC mode, follow these steps to upload an image to an RCP server:
Command Purpose
Step1 Verify that the RCP server is properly configured by
referring to the “Preparing to Download or Upload an Image
File by Using RCP” section on page 20-27.
Step2 Log into the access point through a Telnet session.
Step3 configure terminal Enter global configuration mode.
This step is required only if you override the default remote
username (see Steps 4 and 5).
Step4 ip rcmd remote-username username (Optional) Specify the remote username.
