Thanks. We'll let you know when a new response is added.

Hello,

There are a couple prereqs. You need to have a crypto image (look for k9 in the image name), you need to have an RSA key:

switch(config)#crypto key generate rsa modulus 1024

That should be it. From there, you can do:

line vty 0 15
transport input ssh,telnet

Which effectively enables ssh. Keep in mind that without a crypto image, you can’t generate the key. Without a key, you can use SSH.

Thanks!
