Table 1-1 describes symbols contained in this guide.

CLI Basics

This chapter describes the command structure and command modes. 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 covers the following topics:

• 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 the

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.

The following text is an example of a successful Telnet login session.

telnet 172.31.1.53

Trying 172.31.1.53...

Connected to 172.31.1.53.

Escape character is '^]'.

Password: FTOS>

Once you log into the switch, the prompt provides you with current command-level

information (refer to Table 2-1).

Multiple Configuration Users

When a user enters the CONFIGURATION mode and another user(s) is already in

that configuration mode, FTOS generates an alert warning message similar to the

following:

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 )

FTOS#conf

When another user enters the CONFIGURATION mode, FTOS sends a message

similar to the following, where 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, as 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 the CONFIGURATION mode, the co mm and prompt adds

modifiers to further identify the mode. The command modes are explained in

Command Modes.

Note: Some of the following modes are not available on C-Series or S-Series.

When entering commands, you can take advantage of the following timesaving

features:

• The commands are not case sensitive.

• Y ou can enter partial (truncated) command keywords. For example, you can enter

int gig int interface for the interface gigabitethernet 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.

CLI Basics | 21

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 discussed 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.

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-L Re-enters the previous command.

CNTL-N Return to more recent commands in the history buffer after recalling commands

with Ctrl-P or the up arrow key

CNTL-P Recalls commands, beginning with the last command

CNTL-R Re-enters the previous command.

CNTL-U Deletes the line.

CNTL-W Deletes the previous word.

CNTL-X Deletes the line.

CNTL-Z Ends continuous scrolling of command outputs.

Esc B Moves the cursor back one word.

Esc F Moves the cursor forward one word.

Esc D Deletes all characters from the cursor to the end of the word.

22 | CLI Basics

www.dell.com | support.dell.com

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:

•

display — display additional configuration information

•

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

•

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 would return a search result with instances containing a

capitalized “Ethernet,” such as

interface GigabitEthernet 0/0.

•

show run | grep ethernet would not return the search result, above, because it only

searches for instances containing a non-capitalized “ethernet.”

Executing the command

show run | grep Ethernet ignore-case would return 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 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 comm a nd.For example:

FTOS#show running-config|no-more

Filtering Command Output Multiple Times

You can filter a single command output multiple times. 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

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 gigabit |except regular-expression | find

regular-expression

Determining the Chassis Mode

The chassis mode in FTOS determines which hardware is being supported in an

E-Series chassis. The chassis mode is programmed into an EEPROM on the

backplane of the chassis and the change takes place only after the chassis is rebooted.

Configuring the appropriate chassis mode enables the system to use all the ports on

the card and recognize all software features.
