Configuring the Router
as
show
commands, which show the current configuration status, and
clear
commands, which clear counters or interfaces. The EXEC commands are not
saved across reboots of the router.
The configuration modes allow you to make changes to the running configuration.
If you later save the configuration, these commands are stored and can be used
when you reboot your router. Start at global configuration mode where you can
then enter a specific mode or the system automatically enters ROM monitor mode
when the router cannot boot properly.
ROM Monitor Mode
ROM monitor mode is a separate mode used when the router cannot boot properly.
If your 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 your 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 following example shows the user EXEC mode prompt for
a router with the factory default name Router.
Router>
Note
The default host name is
router
unless it has been changed during initial
configuration using the
setup
command facility.
