1.1.1 Introduction to SSH
Secure shell (SSH) provides secure communication and powerful authentication for
remote user login to a switch over an insecure network, thus preventing assaults such
as IP address spoofing, plain-text password interception.
Acting as an SSH server, a switch allows for the connections of multiple SSH clients.
Through SSH Client, a user can establish a connection to a switch or UNIX host
running SSH Server.
Figure 1-1 and Figure 1-2 shows two ways to establish SSH connection between client
and server.
