Hi,

I'm new in cisco switches and I have to upgrade current IOS CISCO Catalyst 2960S but first of all i want backup current ISO. So i used in cli: sh ver and i saw this:

System image file is "flash:/c2960s-universalk9-mz.122-55.SE3/c2960s-universalk9-mz.122-55.SE3.bin"

In many cases what i saw in internet the IOS bin was in flash directory (flash:/). Is it normal situation and how backup IOS and update?

Hi there,

That boot variable indicates that archive download-sw command was used on a TAR file to install the currently running IOS. As such the .bin file is in a directory of the same name.

It is perfectly fine to copy the .bin file to flash: and update the boot var accordingly.

However using the universal image TAR file and the archive download-sw command gives you some additional arguments to help with software installations and would be my recommendation even if it is to just the /image-only flag.

 

To backup the image simply use the command:

copy flash:/c2960s-universalk9-mz.122-55.SE3/c2960s-universalk9-mz.122-55.SE3.bin tftp:

 

...or some other destination location/service of your choosing.

 

cheers,

Seb.

Go to the Cisco website and download the existing IOS.

Gahhh!  You want a "backup" of 12.2(55)SE3?  WHY?  It's not stable enough to keep.

Ok got the current IOS and i have another little question: in web gui's cisco switch i have update option. So you suggest update from cli or by www?

CLI everytime. The webGUI is pretty flaky!

 

I can't find supportet ios verios for my model WS-C2960S-48TS-S. Website suggesting me 15.0.2-SE11 but in supported hardware list i don't see WS-C2960S-48TS-S.

https://software.cisco.com/download/home/282867582/type/280805680/release/15.0.2-SE11

 

...that is the recommended version for your specific switch.

Thank you.
