TFTP file too large for upload

[Bernard Magny]

I'm trying to upgrade my router via TFTP. I keep getting this File too large for TFTP error. I'm using the recommended TFTP server from Solarwinds.

There does not seem to be any setting in the server to let large file pass, It's the first time I see that, but this is the biggest IOS I had to upload. I had no problem sending the last IOS witch is only about 3MB smaller.

If the image size is over 32MB then you might be running in CSCee67733. The workaround would be to use FTP instead of tftp to download the image on the device.

What level of code are you running on router.

Hope this helps,

Bernard,

To make sure whether CSCee67733 is an issue or not, can you tell us precisely what IOS image is currently running on the 3725. 14.x is not an IOS image.

Thx,

The limitation is not with the switch but with the SolarWinds TFTP Server.

Use 3Com's 3CDaemon Utility:

It can handle large TFTP files with no issues.

Please rate all helpful posts.

Brad,

Your statement about the limitation not being on the switch (router in this case) is pretty categoric. If you use an IOS image that does not integrate CSCee67733 then the router will not support file xfers larger then 32MB.

Hope this helps,

Harold,

Im afraid the bug (CSCee67733) you cite describes using the IOS as the TFTP Server, not as the client, and therefore does not apply to the problem at hand.

Respectfully,

Brad

Brad,

I just checked the DDTS again and found that the release notes are somewhat misleading. The issue happens whether the router is used as a client or a server but only when the file is being copied from the router to the other device.

So, you are right that in this case the issue is probably with the TFTP software being used.

I apologize for the confusion and thanks for pointing it out.

Try TFTPd32

http://tftpd32.jounin.net/

It works fine with large files as well.
