Hi Guys - I am taking security copies of controller configurations from WLCs. The problem I see is that I get inconsistent file sizes and I wondered if anyone knows what might be causing this and what the "typical" file size would be?
Two controllers - both on 4.1.185 - one upload is 755kb, another one is 40kb. Huh!? Doesn't seem right but I can't look into the file and see if it looks complete.
They are pretty much identical, but I don't think that will account for such a huge disparity.
However we may have tracked this down - the tftp protocol uses UDP to send the data, I think that the UDP transfer is dropping because the tftp server that I use shows an error message although the WLC simply says "Completed".
Another clue here is that if we do the same transfer several times we get different file sizes....

The script should be completely self explanatory.
