The Secure Shell (SSH) includes server/client applications intended as a
secure replacement for the older Berkley remote access tools. SSH can also
provide remote management access to this switch as a secure replacement
for Telnet. When a client contacts the switch via the SSH protocol, the
switch uses a public-key that the client must match along with a local user
name and password for access authentication. SSH also encrypts all data
transfers passing between the switch and SSH-enabled management
station clients, and ensures that data traveling over the network arrives
unaltered.
This section describes the commands used to configure the SSH server.
However, note that you also need to install an SSH client on the
management station when using this protocol to configure the switch.
Note: The switch supports both SSH Version 1.5 and 2.0.
