Hello,
I have a Catalyst 2960 switch (2960-8TC-L) and running Software version  12.2(53)SE1.
I mange to configure SSH to the switch and add addition user as well.
Now I need to configure this switch password less login with public key SSH authentication. I configured several Linux servers and Workstations for the public key SSH authentication.
So far I could not figure out how to do this in CISCO switch. Following link http://blog.ioshints.info/2009/10/ssh-rsa-authentication-works-in-ios.html show how to do this.
But ip ssh pubkey-chain command never work showed invalid command.

Anybody could show me to right direction?

ip ssh pubkey-chain is first supported in IOS version 15.0. Before that the ssh server only uses username/password authentication.

Hello, I could read in a couple forum threads, the password-less authentication is only possible in IOS version 15.

Why is there then the command -> "ip ssh pubkey-chain"?

There are various ways to import the Key `s??

Can someone explain this?Is there another ways to password-less authentication in the Major Release 12?


Thanks in advance...
