Working with Software Images
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.
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 software image. All the files in the directory and the directory are removed.
Caution For the download and upload algorithms to operate properly, do not rename image names.
Uploading an Image File By Using FTP
You can upload an image from the switch to an FTP server. You can later download this image to the
same switch or to another switch of the same type.
Use the upload feature only if the web management pages associated with the embedded device manager
have been installed with the existing image.
Beginning in privileged EXEC mode, follow these steps to upload an image to an FTP server:
Command Purpose

Verify that the FTP server is properly configured by referring
to the “Preparing to Download or Upload a Configuration
File By Using FTP” section on page C-13.
Step 2

session.
Step 3
