Networking and In scenarios where users log into a switch over an insecure network by using Configuration another switch, SSH can be used to ensure the security of data exchange to the Requirements 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.
