Copy image from USB to 2821 Bob Wilson 11-19-09

I am trying to put a new IOS image on a 2821 box, and TFTP after many
many tries with different PCs is not working. I have a USB drive
formatted to FAT that has the image on it, and when I do #sh usbflash0
it sees the image and lists the filename correctly. But when I try
#copy usbflash0 flash and a few other things, it tells me the source
and destination are the same.

I did RTFM as best I could -- I have a library of Cisco books but I
did all my Cisco stuff ten years ago when there were no USB ports.
One post in this loop says "copy the image from your USB drive..."
but doesn't say how. So I think it must be possible.

Thanks in advance for help,

Bob Wilson

PS -- It's not the USB I'm so interested in solving, it's getting the
image onto the router. If I'm barking up the wrong tree, somebody
tell me and suggest another way I can get it on there. Thanks again

copy ftp flash

I'd thought of that earlier but didn't have an FTP server locally.
Since you suggested it, I got a server and installed it, and the image
slurped right over without a hitch. Thanks much

Some tftp servers have limitations on the size of file that can be
transferred, and 2821 images can be pretty large. I've had success with
the latest tftp server from Solarwinds, and it's free.
