Using the Command-Line Interface
User EXEC Mode
After you access the device, you are automatically in user EXEC command mode. The EXEC commands
available at the user level are a subset of those available at the privileged level. In general, use the user
EXEC commands to temporarily change terminal settings, perform basic tests, and list system
information.
The supported commands can vary depending on the version of software in use. To display a
comprehensive list of commands, enter a question mark (?) at the prompt.

Privileged EXEC Mode
Because many of the privileged commands configure operating parameters, privileged access should be
password-protected to prevent unauthorized use. The privileged command set includes those commands
contained in user EXEC mode, as well as the configure privileged EXEC command through which you
access the remaining command modes.
If your system administrator has set a password, you are prompted to enter it before being granted access
to privileged EXEC mode. The password does not appear on the screen and is case sensitive.
The privileged EXEC mode prompt is the device name followed by the pound sign (

Enter the enable command to access privileged EXEC mode:

The supported commands can vary depending on the version of software in use. To display a
comprehensive list of commands, enter a question mark (?) at the prompt.

To return to user EXEC mode, enter the disable privileged EXEC command.
Global Configuration Mode
Global configuration commands apply to features that affect the device as a whole. Use the configure
privileged EXEC command to enter global configuration mode. The default is to enter commands from
the management console.
When you enter the configure command, a message prompts you for the source of the configuration
commands:
Switch# configure
Configuring from terminal, memory, or network [terminal]?
You can specify either the terminal or NVRAM as the source of configuration commands.
This example shows you how to access global configuration mode:
Switch# configure terminal
Enter configuration commands, one per line.
