Usage Guidelines

Table 5-1 provides a description of the keys used to enter and edit commands. The letters Ctrl indicates the Control key. It must be pressed simultaneously with its associated letter key. The letters Esc indicates the Escape key. It must be pressed first, followed by its associated letter key. Keys are case sensitive.

Table 5-1 : Editing Keys and Functions

Keys	Function
Tab	Completes a partial command name entry. When you enter a unique set of characters and press the Tab key, the system completes the command name. If you enter a set of characters that could indicate more than one command, the system beeps to indicate an error. Enter a question mark (?) immediately following the partial command (no space). The system provides a list of commands that begin with that string.
Delete or Backspace	Erases the character to the left of the cursor.
Return	At the command line, pressing the Return key performs the function of processing a command. At the "---More---" prompt on a terminal screen, pressing the Return key scrolls down a line.
Space Bar	Allows you to see more output on the terminal screen. Press the space bar when you see the line "---More---" on the screen to display the next screen.
Left Arrow1	Moves the cursor one character to the left. When you enter a command that extends beyond a single line, you can press the Left Arrow key repeatedly to scroll back toward the system prompt and verify the beginning of the command entry.
Right Arrow1	Moves the cursor one character to the right.
Up Arrow1 or Ctrl-P	Recalls commands in the history buffer, beginning with the most recent command. Repeat the key sequence to recall successively older commands.
Down Arrow1 or Ctrl-N	Return to more recent commands in the history buffer after recalling commands with the Up Arrow or Ctrl-P. Repeat the key sequence to recall successively more recent commands.
Ctrl-A	Moves the cursor to the beginning of the line.
Ctrl-B	Moves the cursor back one character.
Ctrl-D	Deletes the character at the cursor.
Ctrl-E	Moves the cursor to the end of the command line.
Ctrl-F	Moves the cursor forward one character.
Ctrl-K	Deletes all characters from the cursor to the end of the command line.
Ctrl-L and Ctrl-R	Redisplays the system prompt and command line.
Ctrl-T	Transposes the character to the left of the cursor with the character located at the cursor.
Ctrl-U and Ctrl-X	Deletes all characters from the cursor back to the beginning of the command line.
Ctrl-V and Esc Q	Inserts a code to indicate to the system that the keystroke immediately following should be treated as a command entry, not as an editing key.
Ctrl-W	Deletes the word to the left of the cursor.
Ctrl-Y	Recalls the most recent entry in the delete buffer. The delete buffer contains the last ten items you have deleted or cut. Ctrl-Y can be used in conjunction with Esc Y.
Ctrl-Z	Ends configuration mode and returns you to the EXEC prompt.
Esc B	Moves the cursor back one word.
Esc C	Capitalizes the word from the cursor to the end of the word.
Esc D	Deletes from the cursor to the end of the word.
Esc F	Moves the cursor forward one word.
Esc L	Changes the word to lowercase at the cursor to the end of the word.
Esc U	Capitalizes from the cursor to the end of the word.
Esc Y	Recalls the next buffer entry. The buffer contains the last ten items you deleted. Press Ctrl-Y first to recall the most recent entry. Then press Esc Y up to nine times to recall the remaining entries in the buffer. If you bypass an entry, continue to press Esc Y to cycle back to it.

¹ The arrow keys function only with ANSI-compatible terminals.

Example

In the following example, enhanced editing mode is disabled on line 3.

Switch(config)# line 3
Switch(config-line)# no editing

Related Command

terminal editing

enable

To enter privileged EXEC mode, use the enable EXEC command.

enable [level]

Syntax Description

level

(Optional) Privileged level to log into on the switch.

Command Mode

EXEC.

Usage Guidelines

Because many of the privileged commands set operating parameters, privileged access should be password-protected to prevent unauthorized use. If the system administrator has set a password with the enable password global configuration command, you are prompted to enter it before being allowed access to privileged EXEC mode. The password is case sensitive.

If a password has not been set, it is only possible to us the enable command when using the console line. If a level is not specified, it defaults to the privileged EXEC mode, which is level 15.

Example

In the following example, the user enters the enable command and is prompted to enter a password. The password is not displayed on the screen. After the user enters the correct password, the system enters privileged command mode as indicated by the pound sign (#).

Switch> enable
Password:
Switch#

Related Commands

disable
enable password

enable last-resort

To specify what happens if the TACACS and extended TACACS servers used by the enable command do not respond, use the enable last-resort global configuration command. The no form of this command restores the default.

enable last-resort {password | succeed}
no enable last-resort {password | succeed}

Syntax Description

password	Allows you to enable by entering the privileged command-level password.
succeed	Allows you to enable without further question.

Default

Default action is to fail.

Command Mode

Global configuration.

Usage Guideline

The secondary authentication is used only if the first attempt fails. The secondary authentication does not occur if the first authentication is only unsuccessful.
