This section provides you with some basic information about the Cisco IOS
software and includes the following sections:

Cisco IOS Modes of Operation

The Cisco IOS software provides access to several different command modes.
Each command mode provides a different group of related commands.
For security purposes, the Cisco IOS software provides two levels of access
to commands: user and privileged. The unprivileged user mode is called user
EXEC mode. The privileged mode is called privileged EXEC mode and
requires a password. The commands available in user EXEC mode are a subset
of the commands available in privileged EXEC mode.
Table 3-2 describes some of the most commonly used modes, how to enter the
modes, and the resulting prompts. The prompt helps you identify which mode
you are in and, therefore, which commands are available to you.

If AutoInstall completes successfully, enter the copy running-config
startup-config command in privileged EXEC mode to write the configu-
ration data to the router's NVRAM:
Router# copy running-config startup-config
Taking this step saves the configuration settings that the AutoInstall
process created to the router's NVRAM. If you do not do this, the config-
uration will be lost the next time you reload the router.
