Working with Software Images Chapter 20 Managing Firmware and Configurations Deleting a Stored Configuration File Caution You cannot restore a file after it has been deleted. To delete a saved configuration from Flash memory, use the delete flash:filename privileged EXEC command. Depending on the setting of the file prompt global configuration command, you might be prompted for confirmation before you delete a file. By default, the access point prompts for confirmation on destructive file operations. For more information about the file prompt command, refer to the Cisco IOS Command Reference for Release 12.4. Working with Software Images This section describes how to archive (download and upload) software image files, which contain the system software, Cisco IOS software, radio firmware, and the web management HTML files. You download an access point image file from a TFTP, FTP, or RCP server to upgrade the access point software. You upload an access point image file to a TFTP, FTP, or RCP server for backup purposes. You can use this uploaded image for future downloads to the same access point 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. This section includes this information: • Image Location on the Access Point, page 20-18 • tar File Format of Images on a Server or Cisco.com, page 20-19 • Copying Image Files by Using TFTP, page 20-19 • Copying Image Files by Using FTP, page 20-22 • Copying Image Files by Using RCP, page 20-27 • Reloading the Image Using the Web Browser Interface, page 20-32 Note For a list of software images and supported upgrade paths, refer to the release notes for your access point. Image Location on the Access Point The Cisco 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 access point. In the display, check the line that begins with System image file is... It shows 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. 20-18 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points OL-14209-01
