Understanding Command Modes Appendix A Cisco IOS Software Basic Skills Table A-1 Terminal Emulation Software PC Operating System Windows 95, Windows 98, Windows 2000, Windows NT, Windows XP Windows 3.1 Macintosh Software HyperTerm (included with Windows software), ProComm Plus Terminal (included with Windows software) ProComm, VersaTerm (supplied separately) You can use the terminal emulation software to change settings for the type of device that is connected to the PC, in this case a router. Configure the software to the following standard VT-100 emulation settings so that your PC can communicate with your router: • 9600 baud • 8 data bits • No parity • 1 stop bit • No flow control These settings should match the default settings of your router. To change the router baud, data bits, parity, or stop bits settings, you must reconfigure parameters in the ROM monitor. For more information, see Appendix C, "ROM Monitor." To change the router flow control setting, use the flowcontrol line configuration command. For information on how to enter global configuration mode so that you can configure your router, see the "Entering Global Configuration Mode" section later in this chapter. Understanding Command Modes This section describes the Cisco IOS command mode structure. Each command mode supports specific Cisco IOS commands. For example, you can use the interface type number command only from global configuration mode. The following Cisco IOS command modes are hierarchical. When you begin a router session, you are in user EXEC mode. • User EXEC • Privileged EXEC • Global configuration Table A-2 lists the command modes that are used in this guide, how to access each mode, the prompt you see in that mode, and how to exit to a mode or enter the next mode. Because each mode configures different router elements, you might need to enter and exit modes frequently. You can see a list of available commands for a particular mode by entering a question mark (?) at the prompt. For a description of each command, including syntax, see the Cisco IOS Release 12.3 documentation set. Cisco 850 Series and Cisco 870 Series Access Routers Software Configuration Guide A-2 OL-5332-01
