Something went wrong while setting the boot image.

Try the "archive" command instead, with that the boot-image is set automatically:

TFTP is not reliable and can result in transfer errors, you definitely have alot of errors based on your attached output. I would recommend trying to download the new IOS again using a reliable protocol like FTP or RCP or finding and correcting the scource of your errors.

If you get an archived copy of the IOS (the "with web based device manager" version) you would be able to use the archive command to perform the upgrade as well. The archive method downloads the IOS twice and compares them to ensure there were no bit errors. Then performs the full upgrade including setting all the proper boot statements for you.

Best of luck,

Greg

The BIN file is corrupt.  Did you compare the MD5 hash?

[vishalpatil86]

Dear Leo,

I verified with MD 5 hash with original image. The image seemed fine...

One thing I observed while doing show flash, the running ios image doesn't have .bin extension

any suggestion??

[Karsten Iwen]

The running image also has the ".bin" extention, but is installed inside a directory with the same name.

The boot-image is set incorrect. The easy way is to upgrade with the "archive"-command as with that the boot-image is set automatically. If you want to do it by hand, use the right url:

boot system flash:/c2960-lanbasek9-mz.122-55.SE6.bin

(in my first post I wrote incorrectly "upgrade"-command; sorry for that. Just corrected it.)

To me even though it looks like it had a lot of errors , it finished ok and that is the correct  size for that file and  it says "OK"  after the download.  It does a check on the file when its finished.   You can also use the verify command to check the file , try using  "boot system flash:c2960-lanbasek9-mz.122-55.SE6.bin. Also you have to remove the current boot statement if there is one .

Could you copy following commands:

boot system c2960-lanbasek9-mz.122-55.SE6.bin

boot system flash:c2960-lanbasek9-mz.122-55.SE6.bin

do wr

end

reload

?

You need to instruct the file is on the device flash: Regarding your output it takes c29...... as medium.

  I agree there is no pointer in your boot statement pointing it to flash:  .  As in my previous note add

boot system flash:c2960-lanbasek9-mz.122-55.SE6.bin  .  Then remove the current  "no boot system:c2960-lanbasek9-mz.122-55.SE6.bin  .

[vishalpatil86]

Dear Davy,

It worked with below command -

boot system flash:c2960-lanbasek9-mz.122-55.SE6.bin

do wr

end

reload

Ok, can you please post the output to the command "dir" please?

Can you post the output to the command "dir flash:c2960-lanbasek9-mz.122-50.SE5"?
