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 '^]'. Login: username

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 command 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.

Obtaining Help

As soon as you are in a command mode there are several ways to access help.

•To obtain a list of keywords at any command mode, do the following:

CLI Basics | 17

w w w . d e l l . c o m | s u p p o r t . d e l l . c o m

•Enter a ? at the prompt or after a keyword. There must always be a space before the ?.

•To obtain a list of keywords with a brief functional description, do the following:

•Enter help at the prompt.

•To obtain a list of available options, do the following:

•Type a keyword followed by a space and a ?

•Type a partial keyword followed by a ?

•A display of keywords beginning with the partial keyword is listed.

The following text illustrates the results of entering ip ? at the prompt.

FTOS(conf)#ip ?	Named access-list
access-list	Named access-list
as-path	BGP autonomous system path filter
community-list	Add a community list entry
domain-list	Domain name to complete unqualified host name
domain-lookup	Enable IP Domain Name System hostname translation

ssh	SSH configuration commands
tacacs	Interface configuration for TACACS+
telnet	Specify telnet options
tftp	TFTP configuration commands
trace-group	Named trace-list
trace-list	Named trace-list
FTOS(conf)#ip

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

•The commands are not case sensitive.

•You 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

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.

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.

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.

CLI Basics | 19

w w w . d e l l . c o m | s u p p o r t . d e l l . c o m

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

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

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 command.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:

CLI Basics

Command Modes

To navigate to various CLI modes, you need to use specific commands to launch each mode. Navigation to these modes is discussed in the following sections.

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