CLI Basics
This chapter describes the command structure and command modes. The Dell Force10 operating
software (FTOS) commands are in a text-based interface that allows you to use launch commands,
change the command modes, and configure interfaces and protocols.
This chapter includes the following sections:
•Accessing the Command Line
•Multiple Configuration Users
•Navigating the Command Line Interface
•Obtaining Help
•Using the Keyword no
•Filtering show Commands
•Command Modes
Accessing the Command Line
When the system boots successfully, you are positioned on the command line in EXEC mode and not
prompted to log in. You can access the commands through a serial console port or a Telnet session.
When you Telnet into the switch, you are prompted to enter a login name and password.
Figure 2-1 is an example of a successful Telnet login session.
Figure 2-1. Login Example
After you log into the switch, the prompt provides you with current command-level information
(Table 2-1).
telnet 172.31.1.53
Trying 172.31.1.53...
Connected to 172.31.1.53.
Escape character is '^]'.

Multiple Configuration Users
When a user enters CONFIGURATION mode and another user(s) is already in that configuration
mode, FTOS generates an alert warning message similar to Figure 2-2:
Figure 2-2. Configuration Mode User Alert
When another user enters CONFIGURATION mode, FTOS sends a message similar to the following,
(the user in this case is “admin” on vty2):
% Warning: User “admin” on line vty2 “172.16.1.210” is in configuration
Navigating the Command Line Interface
The command line interface (CLI) prompt displayed by FTOS is comprised of:
• “hostname”— the initial part of the prompt, “FTOS” by default. You can change it with the
hostname command, as described in hostname.
• The second part of the prompt, reflecting the current CLI mode, is shown in Table 2-1.
The CLI prompt changes as you move up and down the levels of the command structure.
Table 2-1 lists the prompts and their corresponding command levels, called modes. Starting with
CONFIGURATION mode, the command prompt adds modifiers to further identify the mode. The
command modes are explained in Command Modes.
FTOS#conf
% Warning: The following users are currently configuring the system:
User "" on line console0
User "admin" on line vty0 ( 123.12.1.123 )
User "admin" on line vty1 ( 123.12.1.123 )
User "Irene" on line vty3 ( 123.12.1.321 )

Figure 2-3 shows the results of entering ip ? at the prompt.
Figure 2-3. Partial Keyword Example
When entering commands, you can take advantage of the following time saving features:
• The commands are not case sensitive.
• You can enter partial (truncated) command keywords. For example, you can enter int tengig
interface for the interface tengigabitethernet interface command.
• Use the TAB key to complete keywords in commands.
• Use the up arrow key to display the last enabled command.
• Use either the Backspace key or the Delete key to erase the previous character.

Use the left and right arrow keys to navigate left or right in the FTOS command line. Table 2-2
defines the key combinations valid at the FTOS command line.
Using the Keyword no
To disable, delete, or return to default values, use the no form of the commands. For most commands,
if you type the keyword no in front of the command, you will disable that command or delete it from
the running configuration. In this document, the no form of the command is described in the
“Command Syntax” portion of the command description.
Filtering show Commands
You can filter the display output of a show command to find specific information, to display certain
information only, or to begin the command output at the first instance of a regular expression or phrase.
When you execute a show command, followed by a pipe ( | ) and one of the parameters listed below
and a regular expression, the resulting output either excludes or includes those parameters, as defined
by the parameter:
•except— display only text that does not match the pattern (or regular expression)
•find — search for the first occurrence of a pattern
•grep — display text that matches a pattern
Table 2-2. Short-cut Keys and their Actions
Key
Combination Action
CNTL-A Moves the cursor to the beginning of the command line.
CNTL-B Moves the cursor back one character.
CNTL-D Deletes character at cursor.
CNTL-E Moves the cursor to the end of the line.
CNTL-F Moves the cursor forward one character.
CNTL-I Completes a keyword.
CNTL-K Deletes all characters from the cursor to the end of the command line.
CNTL-N Return to more recent commands in the history buffer after recalling commands with Ctrl-P
or the up arrow key

•no-more — do not paginate the display output
•save — copy output to a file for future use
The grep command option has an ignore-case sub-option that makes the search case-insensitive. For
example, the commands:
•show run | grep Ethernet returns a search result with instances containing a capitalized
“Ethernet,” such as interface TenGigabitEthernet 0/0.
•show run | grep ethernet does not return the search result above because it only searches for
instances containing a non-capitalized “ethernet”.
•show run | grep Ethernet ignore-case returns instances containing both “Ethernet” and
“ethernet”.
Displaying All Output
To display the output all at once (not one screen at a time), use the no-more command after the pipe.
This is similar to the terminal length screen-length command except that the no-more option affects
the output of just the specified command. For example:
FTOS#show running-config | no-more
Filtering Command Output Multiple Times
You can filter a single command output multiple times. To do this, place the save option as the last
filter. For example:
FTOS# command | grep regular-expression | except regular-expression | grep
other-regular-expression |find regular-expression | no-more | save
Command Modes
To navigate to various CLI modes, use specific commands to launch each mode. Navigation to these
modes is described in the following sections.
EXEC Mode
When you initially log in to the switch, by default you are logged into EXEC mode. This mode allows
you to view settings and to enter EXEC Privilege mode to configure the device. While you are in
EXEC mode, the >prompt is displayed following the “hostname” prompt (which is “FTOS” by
default). You can change this using the hostname command. For more information, refer to the
hostname command. Each mode prompt is preceded by the hostname.
Note: FTOS accepts a space before or after the pipe, no space before or after the pipe, or any
combination. For example:
FTOS#command | grep tengigabit |except regular-expression | find
regular-expression
