Hello folks,

 

I am trying to upgrade a Cisco 3750G to fix stack mismatch.

 

I have undone the stack and trying to upgrade those switches with new IOS.

 

I get "!o!" using tftp so I used;

USP-CISCO-SW5#archive download-sw /overwrite /reload tftp: flash:
 Could not buffer tarfile...using multiple downloads
examining image...
%Error opening tftp: (Invalid IP address or hostname)
%Error opening flash:update/info (No such file or directory)
ERROR: Image is not a valid IOS image archive.
USP-CISCO-SW5#

 

stil I get error.

 

Please advsie what I should do to get this working correctly? reset the sw to factory default? trying to avoid doing that.

Please advise,

 

Regards,

 

Masood

Hi,

if the IOS is in .bin format and not .tar, this command still valid?

Best Regards,
