Issue downloading cisco IOS using TFTP

[kamrannaseem]

Hi All,

I have installed Solarwind TFTP on my windows xp machine and trying to downgrade my cisco switch image to c3750-ipbasek9-tar.122-35.SE5.tar

the current version is "flash:/c3750-ipbasek9-mz.122-55.SE5/c3750-ipbasek9-mz.122-55.SE5.bin"

Gives me the following errorrs when i try to download the image.

Could not buffer tarfile...using multiple downloads

examining image...

%Error opening tftp://128.1.97.55/c3750-ipbasek9-tar.122-35.SE5.tar (Timed out)

%Error opening flash:update/info (No such file or directory)

ERROR: Image is not a valid IOS image archive.

any help will be much appriciated.

Many thanks.

Are you using the tar command or the copy command?

Hi Kamran,

first please check your TFTP server is reachable from your switch.If yes ? then check your flash memory space using "dir flash:"  command.If you have sufficient flash: memory for new image then use

"archive download-sw /overwrite tftp://128.1.97.55/c3750-ipbasek9-tar.122-35.SE5.tar"
to upload your imange to switch.

There is difference procedure to upload .bin and .tar extension file in switch flash:

Like for .bin

it just simple steps type

"copy tftp flash:" and then just hit enter button, it will ask you for tftp server ip and Image detail.make sure you use .bin extension

Here is document available on cisco.com for

Hope that help

Hi Ashish,

It seems that it copies the image but gives couple of errors at the end :

Error: system number 1 does not support the same feature set.

This means the current feature set is not the same as the feature set you are downgrading to.

Kindly use the "/allow-feature-upgrade".
