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.
