During the TFTP copy of an IOS image to a 6509 switch, the copy started going fine, then started getting out of sequence indicators.
The IOS finished copying, and I see the image on the disk, but I am wondering, should I be concerned about that image?
Or no?

Did the transfer pass the integrety check and file size check?
If you are not sure - delete the file and transfer it again!

Richard,
The verify command is very useful when it comes to that.
If you run it against the image you downloaded, it will report the MD5 value.
You can compare the MD5 value reported to you to the one from the download page, if they match - the image was copied properly.
It should also report if the image is invalid.
HTH,

Edison,
I am getting something totally different on the "Verify"
Done!

What's the image name?
That's odd - I have a 6509 with SXF8 and it matched CCO

Computed Hash MD5 : DA2654E6FCDF4556B065637ABECF33D3
CCO Hash MD5 : 21FC4B0D8FE650D93C88791EF8F5DFD8

_______

Once we verify the image you selected from CCO is the same as the one you have, then we can conclude the image is good or not.

Sorry Edison,
I was a bone head:
MD5 from download page:

It matches, so you are good :)

Don't worry about this. The "O" is a sign of low latency. What matters are the "Ok!" and the Transfer Complete at the end of the process. I see this all the time when I transfer IOS via the low-speed WAN & satellite link.
