what happens when the transport input ssh command is entered on the switch vty lines?
communication between the switch and remote users is encrypted.
the switch requires a username/password combination for remote access.
the ssh client on the switch is enabled.
the switch requires remote connections via a proprietary client software.

SSH (Secure Shell) is a network - protocol that provides secure encrypted communication. When the transport input ssh command is entered on the switch vty (Virtual Teletype) lines, it configures the switch to use SSH for remote access, which encrypts the communication between the switch and remote users.
