I'm struggling to make SSH 2 work on Cisco 3550-PWR router.
It has SSH 1.5/1,9 and complains to generate 768-bit key when I try to activate SSH 2. Even after I generate the keys of 2048, it still complains.
I'm able to SSH in using 1.5/1.9 but not 2 yet.
It's been a while since I've done R&S and could use a little help.
Thanks.

Question 1: Are you using the command ip ssh version 2 to attempt in activating SSH version 2?
Question 2: What is the exact image file name you see in show version?
Question 3: What IOS are you running (Which goes along with question 2)?:study:Reading: Lab Books, Ansible Documentation, Python Cookbook 2018 Goals: More Ansible/Python work for Automation, IPSpace Automation Course [X], Build Jenkins Framework for Network Automation [] -

(1) Yes, and it complains to generate rsa keys of size 768, which I already did.

When it "complains", what error does it give you?:study:Reading: Lab Books, Ansible Documentation, Python Cookbook 2018 Goals: More Ansible/Python work for Automation, IPSpace Automation Course [X], Build Jenkins Framework for Network Automation []

"please create rsa keys to enable ssh2"
BUT, I tried again just now and it works. Seems your reply post did wonder to my switch.
Thank you for that.
