console port and aux port
Console Port and AUX Port
  • The console port and the auxiliary (AUX) port are management ports.
  • These asynchronous serial ports are not designed as networking ports.
  • One of these two ports is required for the initial configuration of the router.
  • The console port is recommended for this initial configuration.
  • Not all routers have an auxiliary port.
console port connection
Console Port Connection
  • When the router is first put into service, there are no networking parameters configured.
  • To prepare for initial startup and configuration, attach an RS-232 ASCII terminal, or a computer emulating an ASCII terminal, to the system console port.
  • Then configuration commands can be entered to set up the router.
  • The router can also be configured from a remote location by dialing to a modem connected to the console or auxiliary port on the router
connect a pc to a router
Connect a PC to a Router
  • The PC or terminal must support VT100 terminal emulation. Terminal emulation software such as HyperTerminal is usually used.
  • To connect the PC to a router:
    • 1. Configure terminal emulation software on the PC for:
      • The appropriate com port
      • 9600 baud
      • 8 data bits
      • No parity
      • 1 stop bit
      • No flow control
    • 2. Connect the RJ-45 connector of the rollover cable to the router console port.
    • 3. Connect the other end of the rollover cable to the RJ-45 to DB-9 adapter.
    • 4. Attach the female DB-9 adapter to a PC.
operating cisco ios software
Operating Cisco IOS Software
  • The Cisco IOS (Internetwork Operating System) software uses a command-line interface (CLI) as the traditional console environment.
  • The IOS is a core technology that extends across most of the Cisco product line.
  • Its operation details may vary on different internetworking devices.
overview of router modes1
Overview of Router Modes
  • 使用者執行模式(User EXEC Mode)
  • 特權執行模式(Privileged EXEC Mode)
  • 整體設定(Global configuration)
  • 界面設定(Interface configuration)
