Description This command specifies the SSH protocol version that will be supported by the SSH server. The
server may be configured as Secure Shell Version 1 (SSH1), Version 2 (SSH2) or both. SSH1 and
SSH2 are different protocols and encrypt at different parts of the packets. SSH1 uses the server as
well as host keys to authenticate systems, whereas SSH2 only uses host keys. SSH2 does not use the
same networking implementation that SSH1 does and is considered a more secure, efficient, and
portable version of SSH that includes Secure FTP (SFTP).
