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.

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.

Router> enable password: <password>

Router#

For information about using passwords, see the “Configuring Global Parameters” section on page 3-57.
