    - - Device Access via Console
        A physical connection is established btw the serial COM port and the console interface of the router/switch
      - Console Access Setup Procedures
        
        which serial port we will use
        
        parameters of the serial interface
        
        terminal emulation
      - Router Access via Mini USB
        connection is made btw the USB port of the host and the mini USB interface of the router.
        
        installation of driver for the USB connection may required
        
        in our computer the Driver will help install a virtual serial interface (emulated serial interface and running on the USB)
        
        now we can use the hyper terminal to connect to the virtual interface
      - Example
        methods are supported by VRP platform to configure the router
