Using Client-Based SSH Authentication
To SSH from the chassis to the SSH client, use the following command.
This method uses SSH version 1 or version 2. If the SSH port is a non-default value, use the ip ssh server port number command
to change the default port number. You may only change the port number when SSH is disabled. Then use the
-p option with the ssh
command.
• SSH from the chassis to the SSH client.
