Configureng Administrator User Login Authentication from a Console Port
In this example, the user name is abc and the password is hello. The RADIUS server
first authenticates the user, and then local authentication is used when the former
authentication cannot be carried out normally. When logging in the router
connected through the console port, only the user whose user name is abc and
password is hello can log on successfully. Otherwise, access to the router is denied.
