Managing Firmware and Configurations
Working with Software Images
This section describes how to archive (download and upload) software image files, which contain the
system software, IOS code, radio firmware, and the web management HTML files.
You download an bridge image file from a TFTP, FTP, or RCP server to upgrade the bridge software.
You upload an bridge image file to a TFTP, FTP, or RCP server for backup purposes. You can use this
uploaded image for future downloads to the same bridge or another of the same type.
The protocol you use depends on which type of server you are using. The FTP and RCP transport
mechanisms provide faster performance and more reliable delivery of data than TFTP. These
improvements are possible because FTP and RCP are built on and use the Transmission Control
Protocol/Internet Protocol (TCP/IP) stack, which is connection-oriented.

For a list of software images and supported upgrade paths, refer to the release notes for your bridge.
Note
Image Location on the Bridge
The IOS image is stored in a directory that shows the version number. A subdirectory contains the HTML
files needed for web management. The image is stored on the system board Flash memory (flash:).
You can use the show version privileged EXEC command to see the software version that is currently
running on your bridge. In the display, check the line that begins with
the directory name in Flash memory where the image is stored.
You can also use the dir filesystem: privileged EXEC command to see the directory names of other
software images you might have stored in Flash memory.
