Working with Software Images
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.
You download a switch image file from a server to upgrade the switch software. You can overwrite the
current image with the new one or keep the current image after a download.
You upload a switch image file to a server for backup purposes. You can use this uploaded image for
future downloads to the switch or another switch of the same type.
