Displaying a List of Cisco IOS Commands and Syntax
ROM-monitor mode is a separate mode used when the router cannot boot properly. For example, the
router might enter ROM-monitor mode if it does not find a valid system image when it is booting, or if
its configuration file is corrupted at startup. See the “ROM-Monitor Command-Line Interface” section
on page 2-7.
Table 2-3 lists and describes frequently used Cisco IOS modes.
The Cisco IOS command interpreter, called the EXEC, interprets and executes the commands you enter.
You can abbreviate commands and keywords by entering just enough characters to make the command
unique from other commands. For example, you can abbreviate the show command to sh and the
configure terminal command to config t.
When you type exit, the router backs out one level. To exit configuration mode completely and return to
privileged EXEC mode, press Ctrl-Z.
