Chapter 3 Installing the Router
Cisco IOS User Interface
ROM monitor mode is a separate mode used when the router cannot boot properly.
If the router does not find a valid system image when it is booting, or if the router
configuration file is corrupt at startup, the system might enter ROM monitor
mode.
User EXEC Mode
After the router boots successfully and loads the Cisco IOS software, the system
software displays the user EXEC mode prompt on the system console. The user
EXEC mode prompt consists of the assigned router host name plus the greater
than bracket (>). The default host name is
router
unless it has been changed
during initial configuration using the
setup
command facility. The user EXEC
mode prompt for a router with the factory default name is Router.

Privileged EXEC Mode
Because many of the privileged commands set operating parameters, privileged
access should be password protected to prevent unauthorized use. To enter
privileged EXEC mode, enter the
enable
command at the user EXEC mode
prompt. If the
enable
secret password was set and saved in memory, the system
prompts you to enter the
enable
secret password. The password is not displayed
on the screen and is case sensitive. When the system accepts the password, it
changes the prompt to the privileged EXEC mode prompt, which consists of the
assigned router host name followed by the pound sign (#). The following example
shows the change from user EXEC mode to privileged EXEC mode on the router
named Router.
