Apr 18, 2016 Catalyst 3850 SSH setup issue. Crypto key generate RSA, I think then specified 1024 bit key size. Cisco said it was optional so then I did no transport input. Jan 31, 2018 crypto key generate rsa Example: Switch (config)# crypto key generate rsa Enables the SSH server for local and remote authentication on the Switch and generates an RSA key pair. Generating an RSA key pair for the Switch automatically enables SSH.

Hi,
Are you aware of any inbound ACLs applied on the VTY lines? Maybe do a show access-list, show ip interface and show run commands to check if an ACL is blocking access on the terminal lines.
If its not an ACL issue, make sure you configured 'login local' on your VTY lines to make use of the local database when connecting in

Check also that you have not disabled SSH access into your VTY lines using the transport command.
Make sure 'transport input ssh telnet' or 'transport input telnet ssh' has been configured
Failing all that it could be an exec-timeout issue, maybe that has been set to low and its automatically logging you out, although this is more unlikely based on your report.
Router(config)# crypto key generate rsa general-keys The name for the keys will be: myrouter.example.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. I did a little research and found out that if I removed the rsa key by using this command ' crypto key zeroize rsa' and then added the 'crypto key generate rsa generate-keys modulus 1024, then that would work. Any thoughts? No service pad. No service password-encryption. Hostname Sales-SW-ACC2. Ip domain name my.company.come.
