Enabling SSH and disabling Telnet

Answered Question

I am trying to enable SSH on a 3560G switch so I can disable Telnet.


Some have mentioned to do an "sh ssh" to see if I have ssh on the switch. It doesn't show. I also have done "transport input ssh" and ssh isn't a valid input method.


So I decided to upgrade the IOS on the switch. I am now at 12.2(52) SE.


But I still cannot configure SSH. I get the same results as mentioned above.


Since this is the latest version of IOS can I not assume that it contains SSH? Or do I need to download a different version of IOS that specifically has SSH in it?


Thanks for your help

There are two versions of Catalyst Switch images (K9/SSH and WIthout SSH). If you do a 'show versi
on' it will display the current version of the IOS running on the switch. If you are running a non-ssh version, you need to upgrade to a ssh (K9) image.

I am at 12.2(52) SE. I downloaded it as a .TAR file.


I see now, I downloaded the wrong file.

Yup, you need a K9/CRYPTO image, e.g:


c3560-ipservicesk9-mz.122-52.SE.bin


You can use the feature nagivator to search for images with 'Secure Shell' support:


www.cisco.com/go/fn


It can be either .tar or .bin does not matter. The .tar image includes the web-gui files (alongwith the .bin IOS image) and does not affect the SSH capability.
