Figure 1. Four Cisco IOS Operation modes and their accesses and exits as a figure.

1.1.1 User EXEC Mode

When you are connected to the router, you are started in user EXEC mode. The user
EXEC commands are a subset of the privileged EXEC commands.

1.1.2 Privileged EXEC Mode

Privileged commands include the following:
Configure – Changes the software configuration.
Debug – Display process and hardware event messages.
Setup – Enter configuration information at the prompts.
Enter the command disable to exit from the privileged EXEC mode and return to user
EXEC mode.

1.1.3 Configuration Mode

Configuration mode has a set of submodes that you use for modifying interface
settings, routing protocol settings, line settings, and so forth. Use caution with
configuration mode because all changes you enter take effect immediately.
To enter configuration mode, enter the command configure terminal and exit by
pressing Ctrl-Z.

1.1.4 No Form

Almost every configuration command also has a no form. In general, use the no form to
disable a feature or function. Use the command without the keyword no to re-enable a
disabled feature or to enable a feature that is disabled by default. For example, IP
