Explanation:

Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices. Communication between the client and seiver is encrypted in both SSH version 1 and SSH version 2. If you want to prevent non-SSH connections, add the “transport input ssh” command under the lines to limit the router to SSH connections only. Straight (non-SSH) Telnets are refused.
