No tftpdnld command

..

After that you go to the cisco site and look up this document :

tells you how to use the flash card. Do read the compatibilty note.

luck, Frans

Right, the 3725 doesn't have tftpdnld.. It has xmodem though! If all else fails, jack the console baud rate up to 115,200, and xmodem in the smallest IOS image you can find. It might complete in 4-5 hours for you... Depending on size of course. This is not going to complete quickly.

There's been way too many 36xx routers I've had to recover for people using xmodem boot. I honestly don't know why they didn't fix that for the 37xx routers. :(

The TFTP boot line here is probably your best bet to troubleshoot..

Maybe throw a '-v' on the end of the line to see verbose error messages to see what is going on?

Hmm, reading up on the process here..

It seems a TFTP boot always needs to have something in CompactFlash to start booting from and then loads the real IOS you want via TFTP.

I'd have to say that xmodem'ing in the smallest IOS in is your best bet.

Thanks - will try the xmodem solution...

Unfortunately I'm now having trouble with XModem

Firstly tried to load c3725-advipservicesk9-mz.124-11.XW7.bin (43948KB) but kept getting "BB0 ERR:File not a valid executable" erors. Then tried a smaller IOS image c3725-ipbasek9-mz.124-15.T13.bin (20527KB) but it is also throwing up the same message but also the error says it is still expecting the original advipservicesk9-mz.124-11.XW7.bin image...

Are the files valid? A common problem is using ftp ascii mode to transfer the files. Use binary mode always. Just to be clear I am not taling about the xmodem transfer but a possible earlier ftp, perhaps from the cisco web site.

cidco publish md5 'checksums' of files. You can check your files if you have an md5 utility. There is one for windows on fourmilab.ch in case you are having trouble.

I found my problem - it was in fact a 3745 - i now have the router up & running with c3745-ipbasek9-mz.124-11.XW7.bin. However, when I try to tftp: the IOS to flash: or slot0: (compact flash) the tftp always times out at the same point... I need to get this version into flash: or onto the compact flash so I can boot as normal.

"O" is out of order packet. Make sure that you don't have a duplex mismatch between the client and the server. tftp is not good at recovering from errors. Start with everything at auto-speed/auto-dup.

Some old tftp clients has bugs. I forget the details now. Use tftpd32.exe if you are on Windows but make sure that it's dhcp server does not cause problems on your network. tftpd32.exe is a perfect tftp server - except that if now comes with unwanted baggage:-)

Run a packet capture on your PC.

I had this once with a tftp server : the image got stuck at the same point during transfers (I always check CRC before uploading) I changed the tftp server to tftp32 (from Jounin) and it ran fine (the upload) As the problem was fixed I did not take time to look for the exact reason why (interactions with Antivirus, mem corruption on my laptop, anything more strange ..)

As Dan has mentioned on the other thread you started, use ftp instead if problems persist. If you use Windows Serv-U is easy to get going. If the server insists on a username/password they look like this on the cisco command line.

copy ftp://user:pass@1.2.3.4/filename flash

It's a standard URL format.
