Introduction to SSH Secure Shell (SSH) can provide information security and powerful authentication to
prevent such assaults as IP address spoofing, plain-text password interception
when users log on to the Switch remotely through an insecure network
environment.
As an SSH server, a switch can connect to multiple SSH clients; as an SSH client, a
switch can establish SSH connections with switch or UNIX host that support SSH
server.
Currently, the Switch 7750 Family supports SSHv2.0 (compatible with SSHv1.5).
