When starting a session, the initial mode is the User EXEC mode. Only a limited subset of
commands are available in User EXEC Mode. This level is reserved for tasks that do not change the
configuration. To enter the next level, the Privileged EXEC mode, a password is required.
The Privileged mode gives access to commands that are restricted on EXEC mode and provides
access to the device Configuration mode.
The Global Configuration mode manages the device configuration on a global level.
The Interface Configuration mode configures specific interfaces in the device.
User EXEC Mode
After logging into the device, the user is automatically in User EXEC command mode unless the
user is defined as a privileged user. In general, the User EXEC commands allow the user to perform
basic tests, and list system information.
The user-level prompt consists of the device "host name" followed by the angle bracket (>).
The default host name is "Console" unless it has been changed using the
hostname
command in
the Global Configuration mode.
Privileged EXEC Mode
Privileged access is password protected to prevent unauthorized use because many of the privileged
commands set operating system parameters: The password is not displayed on the screen and is
case sensitive.
Privileged users enter directly into the Privileged EXEC mode. To enter the Privileged EXEC mode
from the User EXEC mode, perform the following steps:
1
At the prompt enter the command
enable
and press <Enter>. A password prompt is
displayed.
2
Enter the password and press <Enter>. The password is displayed as "*". The Privileged
EXEC mode prompt is displayed. The Privileged EXEC mode prompt consists of the device
"host name" followed by "
#
".
To return from Privileged Exec mode to User EXEC mode, type the
disable
command at the
command prompt.
