Requirements
In scenarios where users log into a switch over an insecure network by using 
another switch, SSH can be used to ensure the security of data exchange to the 
maximum extent. As shown in Figure 100:
Switch A acts as the SSH client and the login username is client001.
Switch B acts as the SSH server, whose IP address is 10.165.87.136.
RSA authentication is required.
