Critical commands, such as con?¬?guration and management, require you to be in
privileged EXEC (enable) mode.
To change to privileged EXEC mode from user EXEC mode, enter the enable command at
the hostname> prompt. If an enable password or an enable secret password is con?¬?gured,
the switch or device will then prompt you for the required password.
When the correct enable password is entered, the switch or device prompt changes from
hostname> to hostname#, indicating that the user is now at the privileged EXEC mode
level. Entering the ? command at the privileged EXEC level will reveal many more
command options than those available at the user EXEC mode level.
To return to the user EXEC level, enter the disable command at the hostname# prompt.
Keyboard Help in the CLI
Cisco devices use Cisco IOS Software with extensive command-line input help facilities,
including context-sensitive help. This topic describes the CLI keyboard help that is
available on Cisco devices.
NOTE If both an enable password and a secret password are set, the secret password is
the one that is required.
NOTE For security reasons, a Cisco network device will not echo, or show on the
screen, the password that is entered. However, if a network device is con?¬?gured over a
modem link, or if Telnet is used, the password is sent over the connection in plain text.
