This chapter describes the Cisco DSLAM user interface, provides instructions for using the command-line interface, and describes how to use the help system. The chapter also describes the command editing and command history features that enable you to recall previous command entries and edit previously entered commands.

This chapter includes the following sections:

Understanding the User Interface

The Cisco DSLAM user interface provides access to several different command modes, each with related commands. For security, the user interface provides three levels of access to commands:

User mode—Called user EXEC mode.
Privileged mode—The privileged mode is called privileged EXEC mode and requires a password.

Note Because all commands available in user EXEC mode are also available in privileged EXEC mode, user EXEC mode is referred to as EXEC mode in this guide.

: From the privileged EXEC mode, you can access global configuration mode and three specific configuration modes:

(ROM) monitor mode—This mode accesses a basic system kernel to which the Cisco DSLAM might default at startup if it does not find a valid system image, or if its configuration file is corrupted.

You can enter commands in uppercase, lowercase, or both. Only passwords are case sensitive. You can abbreviate commands and keywords to a unique number of characters. For example, you can abbreviate the show command as sh. After you enter the command line at the system prompt, press Return to execute the command.

Most configuration commands have a no form. In general, follow these guidelines:

Use the no form of a command to disable a feature or function.
Use the command without the no keyword to re-enable a disabled feature or to enable a feature disabled by default.

The context-sensitive help system allows you to obtain a list of commands available for each command mode or a list of available options for a specific command by entering a question mark (?).

Accessing Command Modes

This section describes how to access the Cisco DSLAM command modes. Table 1-1 lists the following information:

The command mode names.
The method to access that mode.
The prompt you see while in that mode. (For the purpose of this guide, the prompts use the default node name DSLAM.)
The method to exit that mode.

Note Table 1-1 does not include all of the possible ways to access or exit each command mode.

Understanding Command Modes

This section describes the various command modes and their levels of user access, including:

User EXEC Mode

When you log in to the Cisco DSLAM, you are in user EXEC, or simply EXEC, command mode. The EXEC mode commands available at the user level are a subset of those available at the privileged level. The user EXEC mode commands allow you to connect to remote switches, change terminal settings on a temporary basis, perform basic tests, and list system information.

The user EXEC mode prompt consists of the DSLAM host name followed by the angle bracket (>):

Frodo>

DSLAM>

The default host name is DSLAM, unless it has been changed through use of the host name global configuration command.

Privileged EXEC Mode

The privileged EXEC mode command set includes all user EXEC mode commands and the configure command, through which you can access global configuration mode and the remaining configuration submodes. Privileged EXEC mode also includes high-level testing commands, such as debug, and commands that display potentially secure information.

To enter or exit privileged EXEC mode, follow these steps:

	Command	Task
Step 1	`DSLAM> enable Password:password`	Enter privileged EXEC mode from EXECmode.¹
Step 2	`DSLAM#`	Enter privileged EXEC commands.
Step 3	`DSLAM# disable DSLAM>`	Exit privileged EXEC mode and return to EXEC mode.²

¹The prompt changes to the DSLAM host name followed by the pound sign (#).
²The prompt changes back to the DSLAM host name followed by the angle bracket (>).

The system administrator uses the enable password global configuration command to set the password, which is case sensitive. If an enable password was not set, you can access privileged EXEC mode only from the console.

ROM Monitor Mode

ROM monitor mode provides access to a basic system kernel, from which you can boot the Cisco DSLAM or perform diagnostic tests. The system can enter ROM mode automatically if the Cisco DSLAM does not find a valid system image, or if the configuration file is corrupted. The ROM monitor prompt is rommon x> without the DSLAM host name. The x represents the number of commands entered into the prompt.

You can also enter ROM monitor mode by interrupting the boot sequence with the Break key during loading.

To return to EXEC mode from ROM monitor mode, use the cont command:

rommon 1> cont

DSLAM>

Step 3	`DSLAM(cfg-atmsig-diag)# exit`	Exit ATM signaling diagnostics configuration mode and return to global configuration mode. Enter end to return to privileged EXECmode.

Using Context-Sensitive Help

The user interface provides context-sensitive help in all modes. This section describes how to configure and display context-sensitive help.

Configuring Help for Terminal Sessions

The following commands configure full help.

Command	Task
`DSLAM# terminal full-help`	In privileged EXEC mode, configure the current terminal session to receive help for the full set of user-level commands.
`DSLAM(config-line)# full-help`	In line configuration mode, configure a specific line to allow users without privileged access to obtain full help.

Displaying Context-Sensitive Help

To get help specific to a command mode, a command, a keyword, or an argument, perform one of these tasks:

Command	Task
`help`	Obtain a brief description of the help system in any command mode.
`abbreviated-command-entry?`	Obtain a list of commands that begin with a particular character string.
`abbreviated-command-entry<Tab>`	Complete a partial command name.
`?`	List all commands available for a particular command mode.
`command ?`	List the associated keywords of a command.
`command keyword ?`	List the associated arguments of a keyword.

To view a list of commands that begin with a particular character sequence, type those characters followed immediately by the question mark (?). Do not include a space. This form of help is called word help, because it completes a word for you.

In this example, the system displays the possible commands in privileged EXEC mode that begin with "co."

DSLAM# co?

configure  connect  copy

This form helps you determine the minimum subset that you can use to abbreviate a command.

Command Syntax Help

To list keywords or arguments, enter a question mark (?) in place of a keyword or argument. Include a space before the ?. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you have already entered.

This example demonstrates the use of command syntax help to complete the access-list command. Entering the question mark (?) displays the allowed arguments:

DSLAM(config)# access-list ?

  <1-99>     IP standard access list
  <100-199>  IP extended access list

Enter the access list number, 99, followed by a question mark (?) to display the allowed keywords:

DSLAM(config)# access-list 99 ?

  deny    Specify packets to reject
  permit  Specify packets to forward

Enter the deny argument followed by a question mark (?) to display the next argument (host name or IP address) and two keywords:

DSLAM(config)# access-list 99 deny ?

  Hostname or A.B.C.D  Address to match
  any                  Any source host
  host                 A single host address

Enter the IP address followed by a question mark (?) to display a final (optional) argument. The <cr> indicates that you can press Return to execute the command:

DSLAM(config)# access-list 99 deny 131.108.134.0 ?

  A.B.C.D  Wildcard bits
  <cr>
DSLAM(config)# <cr>

The system adds an entry to access list 99 that denies access to all hosts on subnet 131.108.134.0.

Checking Command Syntax

The user interface provides an error indicator (^) that appears in the command string in which you have entered an incorrect or incomplete command, keyword, or argument.

This example shows a command entry that is correct up to the last element:

DSLAM# clock set 13:04:30 28 apr 98

                                 ^
% Invalid input detected at '^' marker.

The caret symbol (^) and help response indicate the location in which the error occurs. To list the correct syntax, re-enter the command, substituting a question mark (?) where the error occurred:

DSLAM# clock set 13:32:00 23 February ?

  <1993-2035> Year
DSLAM# clock set 13:32:00 23 February

Enter the year, using the correct syntax, and press Enter to execute the command:

DSLAM# clock set 13:32:00 23 February 1993

Using the Command History Features

The user interface provides a history or record of commands you enter. You can use the command history feature for recalling long or complex commands or entries, including access lists. With the command history feature, you can complete the tasks in the following sections:

Setting the Command History Buffer Size

By default, the system records ten command lines in its history buffer. Use the following commands to set the number of command lines the system records:

Command	Task
`DSLAM# terminal history [size number-of-lines]`	In privileged EXEC mode, enable the command history feature for the current terminal session.
`DSLAM(config-line)# history [size number-of-lines]`	In line configuration mode, enable the command history feature for a specific line.

Recalling Commands

To recall commands from the history buffer, perform one of these tasks:

Key Sequence/Command	Task
Press Ctrl-P or the Up Arrow key.¹	Recall commands in the history buffer, beginning with the most recent command. Repeat the key sequence to recall successively older commands.
Press Ctrl-N or the Down Arrow key.¹	Return to more recent commands in the history buffer after recalling commands with Ctrl-P or the Up Arrow key. Repeat the key sequence to recall successively more recent commands.
`DSLAM> show history`	While in EXEC mode, list the last several commands you have just entered.

¹The arrow keys function only on ANSI-compatible terminals such as VT100s.

Disabling the Command History Feature

The command history feature is automatically enabled. Use the following commands to disable it:

Command	Task
`DSLAM> terminal no history`	In EXEC mode, disable the command history feature for the current terminal session.
`DSLAM(config-line) # no history`	In line configuration mode, configure the line to disable the command history feature.

Using the Editing Features

The user interface includes an enhanced editing mode that provides a set of editing functions similar to those of the Emacs editor. Using the editing features, you can perform the tasks described in the following sections:

Enabling Enhanced Editing Mode

Although the current software release enables the enhanced editing mode by default, you can disable it and revert to the editing mode of previous software releases. Use the following commands to re-enable the enhanced editing mode:

Command	Task
`DSLAM> terminal editing`	In EXEC mode, enable the enhanced editing features for the current terminal session.
`DSLAM(config-line) # editing`	In line configuration mode, enable the enhanced editing features for a specific line.

Moving Around on the Command Line

Use these keystrokes to move the cursor around on the command line for corrections or changes:

Keystrokes	Task
Press Ctrl-B or press the Left Arrow key.¹	Move the cursor back one character.
Press Ctrl-F or press the Right Arrow key.¹	Move the cursor forward one character.
Press Ctrl-A.	Move the cursor to the beginning of the command line.
Press Ctrl-E.	Move the cursor to the end of the command line.
Press Esc B.	Move the cursor back one word.
Press Esc F.	Move the cursor forward one word.

¹The arrow keys function only on ANSI-compatible terminals such as VT100s.

Completing a Partial Command Name

If you cannot remember a complete command name, you can use Tab to allow the system to complete a partial entry:

Keystrokes	Task
Enter the first few letters and press Tab.	Complete a command name.

If your keyboard does not have Tab, press Ctrl-I instead.

In this example, when you enter the letters conf and press Tab, the system provides the complete command:

DSLAM# conf<Tab>

DSLAM# configure

If you enter an ambiguous set of characters, the system generates an error message. To display the list of legal commands beginning with the specified string, enter a question mark (?) after you see the error message. See the "Using Word Help" section.

Pasting in Buffer Entries

The system provides a buffer that contains the last ten items you deleted. You can recall these items and paste them in the command line by using these keystrokes:

Keystrokes	Task
Press Ctrl-Y.	Recall the most recent entry in the buffer.
Press Esc Y.	Recall the next buffer entry.

The buffer contains only the last ten items you have deleted or cut. If you press Esc Y more than 10 times, you cycle back to the first buffer entry.

Editing Command Lines that Wrap

The new editing command set provides a wraparound feature for commands that extend beyond a single line on the screen. When the cursor reaches the right margin, the command line shifts 10 spaces to the left. You cannot see the first 10 characters of the line, but you can scroll back and check the syntax at the beginning of the command. To scroll back, use these keystrokes:

Keystrokes	Task
Press Ctrl-B or the left arrow key¹ repeatedly.	Scroll back one character at a time to the beginning of a command line to verify that you entered a lengthy command correctly.
Press Ctrl-A.	Return directly to the beginning of the line.

¹The arrow keys function only on ANSI-compatible terminals such as VT100s.

In the following example, the access-list command entry extends beyond one line. When the cursor reaches the end of the line, the line is shifted ten spaces to the left and redisplayed. The dollar sign ($) indicates that the line has been scrolled to the left. Each time the cursor reaches the end of the line, the line is again shifted ten spaces to the left.

DSLAM(config)# access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1

DSLAM(config)# $ 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.25

DSLAM(config)# $t tcp 131.108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq

DSLAM(config)# $108.2.5 255.255.255.0 131.108.1.20 255.255.255.0 eq 45

When you complete the entry, press Ctrl-A to check the complete syntax before pressing Return to execute the command. The dollar sign ($) appears at the end of the line to indicate that the line has scrolled to the right:

DSLAM(config)# access-list 101 permit tcp 131.108.2.5 255.255.255.0 131.108.1$

The Cisco DSLAM default is a terminal screen that is 80 columns wide. If you have a width other than that, use the terminal width command to provide the correct width.

Use line wrapping together with the command history feature to recall and modify previous complex command entries.

Deleting Entries

Use any of these keystrokes to delete command entries if you make a mistake or change your mind:

Keystrokes	Task
Press Delete or Backspace.	Erase the character to the left of the cursor.
Press Ctrl-D.	Delete the character at the cursor.
Press Ctrl-K.	Delete all characters from the cursor to the end of the command line.
Press Ctrl-U or Ctrl-X.	Delete all characters from the cursor to the beginning of the command line.
Press Ctrl-W.	Delete the word to the left of the cursor.
Press Esc D.	Delete from the cursor to the end of the word.

Scrolling Down a Line or a Screen

When you use the help facility to list the commands available in a particular mode, the list is often longer than the terminal screen can display. In such cases, a More prompt appears at the bottom of the screen. To respond to the More prompt, use these keystrokes:

Keystrokes	Task
Press Return.	Scroll down one line.
Press Space.	Scroll down one screen.
Press Esc.	Stop scrolling and return to the main prompt.

Redisplaying the Current Command Line

If you enter a command and a message appears on your screen, you can easily recall your current command line entry. To do so, use these keystrokes:

Keystrokes	Task
Press Ctrl-L or Ctrl-R.	Redisplay the current command line.

Transposing Mistyped Characters

If you have mistyped a command entry, you can transpose the mistyped characters by using these keystrokes:

Keystrokes	Task
Press Ctrl-T.	Transpose the character to the left of the cursor and the character located at the cursor.

Controlling Capitalization

You can capitalize or lowercase words or capitalize a set of letters with these keystrokes:

Keystrokes	Task
Press Esc C.	Capitalize at the cursor.
Press Esc L.	Change the word at the cursor to lowercase.
Press Esc U.	Capitalize letters from the cursor to the end of the word.

Designating a Keystroke as a Command Entry

To use a particular keystroke as an executable command, insert a system code:

Keystrokes	Task
Press Ctrl-V or Esc Q.	Insert a code to indicate to the system that the keystroke that follows should be treated as a command entry, not an editing key.

Disabling Enhanced Editing Mode

To disable enhanced editing mode and revert to the editing mode, use this command in privileged EXEC mode:

Command	Task
`DSLAM# terminal no editing`	Disable the enhanced editing features for the local line.

If you have prebuilt scripts that do not interact well when enhanced editing is enabled, you can disable enhanced editing mode. To re-enable enhanced editing mode, use the terminal editing command.

Ending a Session

After you use the setup command or another configuration command, exit the Cisco DSLAM and quit the session.

To end a session, use this EXEC command:

Command	Task
`DSLAM> quit`	End the session.
