sup 720 ios upgrade

[keyonj]

The problem that I'm having is that when I try to upgrade my Cat6513 IOS to support a flexwan module, the switch tells me that I have run out of space on the sup-bootflash when tftp'ing any image higher than the ip Lan only image s72033-ps-mz.122-17d.SXB4. Normally this would mean that the images are too big, but the sup720 ship with 64MB of flash and the images that I'm trying to upload are only in the neighborhood of 40MB. I have tried reformatting, squeezing, and re-pushing the image but are tranfering, I still get the message that there is no more space left on device. I even tried tftp'ing the image to the bootflash: directory, but I still get the same results.

This is very weird. Any ideas?

Thanks

The problem is not the bootflash size but that most TFTP server applications cannot handle files over 16MB.

Try TFTPd32(I have had pretty good luck with it)

If this one fails as well, use FTP/RCP instead

I've used pumpkin tftp server for years. I've not noticed problems so much with files over 16MB but recently, whether it's Sup-720's or WinXP SP2 or maybe just gig interface on laptop, pumpkin has become unreliable. I moved to FTP for a while.

Downloaded tftpd32 as you said and no problems - I'm converted.
