Introduction to File Transfer via TFTP or HTTP

Image Error Checking during File Transfer

The Access Point performs checks to verify that an image downloaded through HTTP or TFTP is valid. The following checks are performed on the downloaded image:

•Zero Image size

•Large image size

•Non VxWorks image

•AP image

•Digital signature verification

If any of the above checks fail on the downloaded image, the Access Point deletes the downloaded image and retains the old image. Otherwise, if all checks pass successfully, the AP deletes the old image and retains the downloaded image.

These checks ensure that the AP does not enter an invalid image state. The storage of the two images is only temporary to ensure the proper verification; the two images are not be stored in the AP permanently.

Image error checking functions automatically in the background. No user configuration is required.
