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 current running image, the download process stops, and an error message
appears.
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 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 enterin g 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.
Caution For the download and upload algorithms to operate properly, do not rename image names.

Uploading an Image File By Using TFTP

You can upload an image from the switch to a TFTP server. You can later download this image to the
switch or to another switch of the same type.
Use the upload feature only if the HTML pages associated with the device manager have been installed
with the existing image.
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, LRE binary files, and info.ver. After these files
are uploaded, the upload algorithm creates the tar file format.
Caution For the download and upload algorithms to operate properly, do not rename image names.
Copying Image Files By Using FTP
You can download a switch image from an FTP server or upload the image from the switch to an FTP
server.
Command Purpose
Step 1 Make sure that the TFTP server is properly configured; see the
“Preparing to Download or Upload an Image File By Using TFTP”
section on page B-20.
Step 2 Log into the switch through a Telnet session.
Step 3 archive upload-sw
tftp:[[//location]/directory]/image-name.tar
Upload the currently running switch 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.
