Exactly what are you trying to accomplish?
The easiest way to copy the IOS is to go to the Cisco website and download the TAR file. Copying the BIN file from one switch (and later moving it to another switch) doesn't guarantee that the file isn't corrupt.

I have directly download the bin from cisco file so there is need of tar file..?

If you have the BIN file from Cisco then make sure you compare the MD5 hash value of the file downloaded against the value found in the Cisco website.

yogesh1 · ‎11-27-2017

Hi leo,

Can you please guide how to compare md5 value or how to verify the running ios image on cisco switch to download the same image from cisco portal.

Leo Laohoo · ‎11-27-2017

Go to the Cisco Download page.
Find the file you've downloaded.
Hover the prompt above the file.
A pop-up will reveal the MD5 hash value.
Copy that value.
Go to the switch.
Enter the command "verify /md flash:IOS_filename.bin <MD5 hash value>".

HI Leo,

Please help me to find out how to check in which disk ios image is install.

To chechk the md5

verify /md5 filesystem:filename [md5-hash]

example

router#verify /md5 disk0:c7301-jk9s-mz.124-10.bin .....<output truncated>.....Done! verify /md5 (disk0:c7301-jk9s-mz.124-10.bin) = ad9f9c902fa34b90de8365c3a5039a5b router#

Leo Laohoo · ‎11-27-2017

This means the MD5 matches.

yogesh1 · ‎11-27-2017

Hi leo ,

Try this command:

archive upload-sw tftp:[[ // location ] / directory ]/ image-name.tar

Example:

archive upload-sw tftp://10.85.65.13/c3750e-universalk9-mz.150-1.SE3.tar
