Understanding Command Modes - Cisco 1812W - Integrated Services Router Wireless Configuration Manual

Understanding Command Modes

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:
•
•
•
•
•
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
configuration command.
For information on how to enter global configuration mode so that you can configure your router, see
the
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

The following Cisco IOS command modes are hierarchical. When you begin a router session, you are in
user EXEC mode.

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 12.3 documentation set.
