Use the SSH command to configure the SSH server as SSH1, SSH2 or both. The default is SSH2 (SSH version 2). This command should only be enabled or disabled when the SSH server is disabled. This setting should not be changed while the SSH server is running since the actual change only takes place after SSH is disabled or enabled.
