Figure 87   Network diagram for configuring the switch to act as the SSH server and use 
password authentication

 

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.

Configure the SSH server

# Create a VLAN interface on the switch and assign an IP address for it. The SSH 
client will use this address as the destination for SSH connection.
