1.1 SSH Terminal Service Overview
This chapter introduces the secure shell (SSH) feature. When a user telnets to the
switch from an insecure network, the SSH feature can provide secure information and
powerful authentication functionality, thereby protecting the switch from attacks such as
IP address spoofing and clear text password interception attacks.
The switch can act as either SSH server or SSH client. When used as an SSH server,
the switch supports multiple connections with SSH clients; when used as an SSH client,
the switch supports SSH connections with the SSH server-enabled switch, UNIX hosts,
and so on.
Currently, the switch supports SSH 2.0.
