I assume that you can ping the switch's IP address from your workstation.
Did you "enable ssh2" either globally or just for the appropriate VR?
In the SSH2 configuration in SecureCRT, I have "Password" first, followed by all the other options - that way "password" gets attempted first.
You may (in SecureCRT) have to enable additional "Key exchange" options (SSH2 section) or/and additional Ciphers and MAC options (SSH2->Advanced in SecureCRT)

On 'older' XOS versions, you have to install ssh as an additional module (something-ssh.xmod, if I recall correctly) for the appropriate OS. I think it's bundled since 16.x, not sure what the first 20-something version was that had bundled ssh support.

Hope that helps,
Frank

Good response, Frank. I just want to add that 16.2 and 21.1 were the versions where the SSH xmod is built into the EXOS image.
