Description Note that even after you configured the current user interface to support SSH (which
has been enabled), the SSH service is unavailable if no local RSA key exists. After you
configure the RSA key, the configuration takes effect at next login.
If SSH is configured, you must set the authentication method to scheme using the
authentication-mode scheme command to guarantee a successful login. The
configuration of the authentication-mode password or
authentication-mode none command fails the protocol inbound ssh
command.
