Appendix B Working with the Cisco IOS File System, Configuration Files, and Software Images
Working with Software Images
The archive upload-sw command builds an image file on the server by uploading these files in order:
info, the Cisco IOS image, the HTML 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 RCP
You can download a switch image from an RCP server or upload the image from the switch to an RCP
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 same switch or another of the same type.
