assistance getting ios to load from T.F.T.P

tha_dub

Any help would be appreciated

I've got
boot system t.f.t.p. 122-23.bin 192.168.1.64

Saved to config and I was able to backup the existing IOS to the T.F.T.P. so I know that's working. Below is the output when I try to boot from t.f.t.p. I would just copy to flash but it only has 8meg of space so I'd have to delete the existing IOS image which I'm too chicken to do until I understand what I've done wrong here better.
Any ideas?

Thanks!

It should be "boot system t ftp://192.168.1.64/122-23.bin"

Thanks for the help...

Still no go. Same error. I checked the t ftp server on my pc and it says transfer aborted.

EDIT: Something that came to mind. I don't have enough flash space to load this IOS and the existing one. (That was the main reason I wanted to try it from T FTP first) Does the router load it onto flash in the process of loading the ios from t ftp? If so I'm really wasting time. On the other hand I would expect a memory or disk space type of error instead...

THANKS!

Ah. Hmm. I've never actually used the mechanism you're using. If I've T FTP booted something then it was from ROMMON.

So I went ahead and overwrote the flash; Okay so not too scary for the more experienced user but I was a little nervous. It worked no prob.

The strange thing to me was that once it booted the config it actually started loading the
t.ftp image successfully...

I dunno why...

I believe it started loading the tfpt image immediately because the fallback squence is NVRAM, flash (missing after you deleted), tfpt server, then ROM. Or in your case if you explicitly put boot system commands in the config, it'll boot from wherever you tell it to - in this case the tfpt server

Yes it started loading from T FTP once the new IOS was loaded into flash because of the boot system command still in config. What I thought was odd was that with the old IOS it would not get that far before aborting. My only hypothesis as I'm not going to revert to the old IOS to test is that it was somehow too old or not compatible.... Either way I got the most up to date IOS installed that I could given my RAM/Flash.

Thanks!
