Hello,
I created a simple config file, listed below, and tried to copy and paste this config on a 2960-8Port switch. After pasting this file, I receive as error message when I issue this command "show ip ssh SSH Disabled - version 1.99 % Please create RSA Keys to enable SSH (of at least 768 bits size) to enable SSH v2. Authentication timeout: 120 secs; Authentication retries: 3"
I can't figure out why ssh v2 won't enable. I've tried it on several boxes/switches but I still receive the same error message.
Any idea as why this happens.
Thanks in advance.
Best, ~zK

When you issue a "show inventory" command, what is the exact model of switch reported?

My solution that actually worked was
crypto key generate rsa general-keys modulus 4096 label SSH

I had the same issue I even tried using
Crypto key generate rsa usage-key 2048 label SSH. I am still getting the same error that says Please create RSA Keys to enable SSH (of at least 768 bits size) to enable SSH v2.
