Horrible TFTP Problems

[ljb2of3]

Hi all, I'm attempting to upgrade our ExtremeWare switches to 7.8 and cannot get the download image command to work. I've already upgraded all of our XOS switches which worked pretty well. However, every single one of our ExtremeWare switches fails with an error similar to the following:

Shop WRR2 200-48:7 # download image 172.16.10.253 v781b1.Wxtr secondary
Are you sure you want to overwrite the secondary image (Y/N)? y
...
ERROR: Out of sync with TFTP server Expected block 410 got 408
Shop WRR2 200-48:8 #

The numbers are different but the theme is the same every time.

I've tried two versions of solar winds tftp server, 3cserver from 3com, atftpd on a linux box, and even the built in tftp server in our epicenter trial. Some servers fail faster than others, but nothing works...

The switches are all on the same vlan with the tftp server. Ideas?

Just FYI in case anybody finds this from google... I ended up plugging a laptop running a tftp server directly into each switch and was able easily make the transfer.

Seems to me that it kinda defeats the purpose of the network if I have to go plug in directly and not be able to do it from a few switches away, but whatever works I guess.

From my experience with the "wxtr" file it worked across the network when I had to upgrade from 7.1 to 7.4 and use the "wrapper xtr" file, but I never tried going from 7.1 to 7.8. (My understanding, perhaps wrong, is it's only needed going from 7.1 to 7.3. After that it's just the .fxtr file for 200s) Maybe that's too much of a jump, code-wise, from 7.1 to 7.8? I've had good luck with the Extremes, but there are oddities sometimes!

Yeah, the problem wasn't the tftp server over the network. It was the wrapper image code that was the problem.
