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, and the web management files. After these files are uploaded, the upload
algorithm creates the tar file format.
For the download and upload algorithms to operate properly, do not rename image names.
Caution
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.
Instead of using the copy privileged EXEC command or the archive tar privileged EXEC command, we
Note
recommend using the archive download-sw and archive upload-sw privileged EXEC commands to
download and upload software image files.

Preparing to Download or Upload an Image File By Using RCP
RCP provides another method of downloading and uploading image files between remote hosts and the
switch. Unlike TFTP, which uses User Datagram Protocol (UDP), a connectionless protocol, RCP uses
TCP, which is connection-oriented.
To use RCP to copy files, the server from or to which you will be copying files must support RCP. The
RCP copy commands rely on the rsh server (or daemon) on the remote system. To copy files by using
RCP, you do not need to create a server for file distribution as you do with TFTP. You only need to have
access to a server that supports the remote shell (rsh). (Most UNIX systems support rsh.) Because you
are copying a file from one place to another, you must have read permission on the source file and write
permission on the destination file. If the destination file does not exist, RCP creates it for you.
RCP requires a client to send a remote username on each RCP request to a server. When you copy an
image from the switch to a server by using RCP, the Cisco IOS software sends the first valid username
