Requirements
In scenarios where users log into a switch over an insecure network, SSH can be
used to ensure the security of data exchange to the maximum extent. As shown in
Figure 87, establish an SSH connection between the host (SSH client) and the
switch (SSH server) for secure data exchange. The host runs SSH2 client software.
Password authentication is required.
