Disabeling SSH Version 1 on a cisco switch

I am currently running a Cisco 3560 48 TS Switch with 12.2(25)SEE3. I am trying to disable version 1 of the protocol, but unable to. I have used no ip ssh version 1 and I still see SSHv1/2 Servers running with the show ssh command. Is there a command or set of commands to shut down ssh version 1 ?

a show ip version says version 1.99.

How do I get it to select 2.0 so it does not use version 1?

Configuring 'ip ssh version 2' should disable support for version 1.

Here's an excerpt from the link below.

Note SSH Version 1 is a protocol that has never been defined in a standard. If you do not want your router to fall back to the undefined protocol (Version 1), you should use the ip ssh version command and specify Version 2.

In addition to sundar's post, when you enable SSH version 2, it always shows as 1.99 in the IOS the reason for which is not known :-)
