Introduction

Locating the IOS image on the Autonomous Access Point

Solution

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 withSystem 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.

Software images located on a server or downloaded from Cisco.com are provided in a tar file format, which contains these files: 

  • info file
  • The info file is always at the beginning of the tar file and contains information about the files within it.
  • Cisco IOS image
  • Web management files needed by the HTTP server on the access point
  • radio firmware 5000.img file
  • info.ver file

The info.ver file is always at the end of the tar file and contains the same information as the info file. Because it is the last file in the tar file, its existence means that all files in the image have been downloaded.

Note The tar file sometimes ends with an extension other than .tar.


Copying Image Files by Using TFTP

You can download an access point image from a TFTP server or upload the image from the access point to a TFTP server.

You download an access point image file from a server to upgrade the access point software. You can overwrite the current image with the new one.

You upload an access point image file to a server for backup purposes; this uploaded image can be used for future downloads to the same or another access point of the same type.
