I use TFTPD32 for all my tftp transfers and have not had a problem with
files larger than 32MB yet.
I have done several TFTP transfers of 80MB or more.

Sometimes I have to configure "no ip ftp passive" to get this to work.

Subject: Limit on TFTP file size - funny that should not work but did..
Hi all,
I am posting this because I can not find a valid answer. I am aware that
tha
maximum file transfer size for TFTP is 16MB. I have lab'ed this on
numberous
times and always I get a protocol error when I reach this limit.
I am on site right now doing a cutover (Enterasysout and 6509 in) and
had to
convert the CatOS to IOS on a SUP720 - CatOS8.5.6.
I can FTP all the images from the switch and MSFC to the FTP server. FTP
access to the server is perfect from all devices. However when I try FTP
a new
image onto the disk0: it fails. Yes the disk is formatted. The FTP
server
shows the file access attempt, but then everything dies - consoles are
dead -
I tried this on 2 different SUPs. I have to reboot the 6509 chassis to
get
console again. I can however FTP any small image - less than a 9MB up to
the
systems successfully. I sent the PIX firewall 7.22 code as a test.
I even logged a TAC case with this. Ths short answer from TAC was to use
TFTPD32 which I did. I queried the file size anyhow and the TFTP limits.
What
happened next confussed me. I successfully sent a 45MB file via TFTP to
the
disk0: and also to bootflash:
This should not have worked.
Anyway - after the conversion to IOS was complete, I tried FTP again and
everything works.
Can anyone explain why this worked? Is this a bug or is this TFTPD32
program
somehow breaking TFTP to support this larger file size? I did not try
TFTP
after that again since it should never have worked at all in the 1st
place
Regards
Andrew
