Preface
About this Document
This CLI Reference Guide describes how to use the CLI and a list of the CLI
commands and their arguments.
The CLI commands described in this document are organized according to
feature groups in separate sections.
This section describes how to use the CLI. It contains the following topics:
• CLI Command Modes
• Starting the CLI
• CLI Command Conventions
• Entering Commands
CLI Command Modes
To configure devices, the CLI is divided into various command modes. Each
command mode has its own set of specific commands. Entering a question
mark "?" at the console prompt displays a list of commands available for that
particular command mode.
A specific command, which varies from mode to mode, is used to navigate
from one mode to another. The standard order to access the modes is as
follows:
User EXEC
mode,
Privileged EXEC
mode,
Global Configuration
mode, and
Interface Configuration
modes.
When starting a session, the initial mode for non-privileged users is the User
EXEC mode. Only a limited subset of commands is available in the User
EXEC mode. This level is reserved for tasks that do not change the
configuration.

Privileged users enter the Privileged EXEC mode directly using a password.
This mode provides access to the device Configuration modes.
The modes are described below.
User EXEC Mode
After logging into the device, the user is automatically in
User EXEC
command mode unless the user is defined as a privileged user. In general, the
User EXEC
commands enable the user to perform basic tests, and display
system information.
The user-level prompt consists of the device "host name" followed by the
angle bracket (>).
console>
The default host name is "console" unless it has been changed using the
hostname command in the
Global Configuration
mode.
Privileged EXEC Mode
Privileged access is password-protected to prevent unauthorized use, because
many of the privileged commands set operating system parameters: The
password is not displayed on the screen and is case sensitive.
Privileged users enter directly into the
Privileged EXEC
mode.
Use disable to return to the
User EXEC
mode.
Global Configuration Mode
Global Configuration
mode commands apply to features that affect the
system as a whole, rather than just a specific interface.
To enter the
Global Configuration
mode, enter configure in the Privileged
EXEC mode, and press <Enter>.
The
Global Configuration
mode prompt is displayed.
console(config)#
Use exit, end or ctrl/z to return to the Privileged EXEC mode.
Interface Configuration Modes
Commands in the following modes perform specific interface operations:

•
Line Interface
— Contains commands to configure the management
connections. These include commands such as line speed, timeout
settings, etc. The
Global Configuration
mode command
line
is used to
enter the
Line Configuration command
mode.
•
VLAN Database
— Contains commands to create a VLAN as a whole.
The Global Configuration mode command
vlan database
is used to enter
the
VLAN Database Interface Configuration
mode.
•
Management Access List
— Contains commands to define management
access-lists. The
Global Configuration
mode command management
access-list is used to enter the
Management Access List Configuration
mode.
•
Port Channel
— Contains commands to configure port-channels, for
example, assigning ports to a VLAN or port-channel. The
Global
Configuration
mode command interface
port-channel
is used to enter the
Port Channel Interface Configuration
mode.
•
SSH Public Key-Chain
— Contains commands to manually specify other
device SSH public keys. The
Global Configuration
mode command crypto
key pubkey-chain
ssh
is used to enter the
SSH Public Key-chain
Configuration
mode.
•
Interface
— Contains commands that configure the interface. The
Global
Configuration
mode command
interface
is used to enter the
Interface
Configuration
mode.
Starting the CLI
The switch can be managed over a direct connection to the switch console
port, or via a Telnet connection. The switch is managed by entering
command keywords and parameters at the prompt. Using the switch CLI
commands is similar to entering commands on a UNIX system.
If access is via a Telnet connection, ensure the device has an IP address
defined, corresponding management access is granted, and the workstation
used to access the device is connected to the device prior to using CLI
commands.
Accessing the CLI from the Console Line
1. Start the device and wait until the startup procedure is complete. The User
Exec mode is entered, and the prompt "console>" is displayed.

2. Configure the device an d enter the necessary commands to complete the
required tasks.
3. When finished, exit the session with the quit or exit comma nd.
Accessing the CLI from Telnet
1. Enter telnet and the IP address of the device. A User Name prompt is
displayed.
2. Enter the User Name and Password. You are in the Privileged Exec mode.
3. Configure the device an d enter the necessary commands to complete the
required tasks.
4. When finished, exit the session with the quit or exit command.
When another user is required to log onto the system, the login command is
entered in the Privileged EXEC command mode,. This effectively logs off the
current user and logs on the new user.
CLI Command Conventions
The following table describes the command syntax conventions.
Conventions Description
[ ] In a command line, square brackets indicates
an optional entry.
{ } In a command line, curly brackets indicate a
selection of compulsory parameters separated
by the | character. One option must be
selected. For example: flowcontrol
{auto|on|off} means that for the flowcontrol
command either auto, on or off must be
selected.
Italic font Indicates a parameter.
<Enter> Any individual key on the keyboard. For
example click <Enter>.
Ctrl+F4 Any combination keys pressed simultan eously
on the keyboard.

Entering Commands
A CLI command is a series of keywords and arguments. Keywords identify a
command, and arguments specify configuration parameters. For example, in
the command "show interfaces status gi1/0/5" show, interfaces and status are
keywords, gi is an argument that specifies the interface type, and 1/0/5 is an
argument that specifies the port.
To enter commands that require parameters, enter the required parameters
after the command keyword. For example, to set a password for the
administrator, enter:
console(config)# username admin password smith
Help information can be displayed in the following ways:
•
Keyword Lookup
— The character ? is entered in place of a command. A
list of all valid commands and corresponding help messages are displayed.
•
Partial Keyword Lookup
— A command is incomplete and the character ?
is entered in place of a parameter. The matched parameters for this
command are displayed.
The following describes features that assist in using the CLI:
Terminal Command Buffer
Every time a command is entered in the CLI, it is recorded on an internally
managed Command History buffer. Commands stored in the buffer are
maintained on a First In First Out (FIFO) basis.These commands can be
Screen Display Indicates system messages and prompts
appearing on the console.
all When a parameter is requi red to defin e a range
of ports or paramete rs and all is an option, the
default for the command is all when no
parameters are defined. For example, the
command interface range port-channel has
the option of either entering a range of
channels, or selecting all. When the command
is entered without a parameter, it automatically
defaults to all.

recalled, reviewed, modified, and reissued. This buffer is not preserved across
device resets. The keys that can be used to access the history buffer are
described in Tab l e 1 .
By default, the history buffer system is enabled, but it can be disabled at any
time. For information about the command syntax to enable or disable the
history buffer, see the history command.
There is a standard default number of commands that are stored in the buffer.
The standard number of 10 commands can be increased to 256. By
configuring 0, the effect is the same as disabling the history buffer system. For
information about the command syntax for configuring the command history
buffer, see the history size command.
To display the history buffer, see show history command.
Negating the Effect of Commands
For many configuration commands, the prefix keyword "no" can be entered to
cancel the effect of a command or reset the configuration to the default
value. This guide describes the negation effect for all applicable commands.
Command Completion
If the command entered is incomplete, invalid, or has missing or invalid
parameters, an appropriate error message is displayed.
To complete an incomplete command, press the <Tab> button. If the
characters already entered are not enough for the system to identify a single
matching command, press "?" to display the available commands matching
the characters already entered.
Incorrect or incomplete commands are automatically re-entered next to the
cursor. If a parameter must be added, the parameter can be added to the basic
command already displayed next to the cursor. The following example
indicates that the command interface requires a missing parameter.
(config)#interface
%missing mandatory parameter
(config)#interface

User Guidelines
A macro can contain up to 3000 characters and up to 200 lines. Enter one
macro command per line. Use the @ character to end the macro. Use the #
character at the beginning of a line to enter comment text within the macro.
You can define mandatory keywords within a macro by using a help string to
specify the keywords. Enter #macro keywords word to define the keywords
that are available for use with the macro. The keyword name is case sensitive.
You can enter up to three keywords separated by a space. Only the first three

keywords are visible if you enter more than three macro keywords. The
command can be anywhere within the macro.
When creating a macro, do not use the exit or end commands or change the
command mode using interface interface-id. Doing so might cause
commands that follow exit, end or interface interface-id to be executed in a
different command mode.
You can modify a macro by creating a new macro with the same name as the
existing macro. The newer macro overwrites the existing macro.
Examples
The following example shows how to create a macro that defines the duplex
mode and speed:
Switch(config) # macro name dup
Enter macro commands one per line. End with the character ‘@’.
macro description dup
duplex full
speed auto
The following example shows how to create a macro with #macro keywords:
Switch(config) # macro name duplex
Enter macro commands one per line. End with the character ‘@’.
macro description duplex
duplex $DUPLEX
speed $SPEED
#macro keywords $ DUPLEX $ SPEED
@
The following example shows how to apply the macros to an interface:
Switch(config-if) # macro apply duplex $DUPLEX full $SPEED auto
Switch(config-if) # macro apply duplex ?
WORDkeyword to replace with value e.g. $DUPLEX, $SPEED

Use the macro apply interface configuration command to apply a macro to an
interface or to apply and trace a macro configuration on an interface.
Syntax
macro {
apply | trace} macro-name [parameter {value}] [parameter {value}]
[parameter {value}
]
Parameters
•
apply
—Apply a macro to the specific interface.
•
trace
—Apply and trace a macro to the specific interface.
•
macro-name
—Specify the name of the macro.
•
parameter
—(Optional) Specify unique parameter values that are specific
to the interface. You can enter up to three keyword-value pairs. Parameter
keyword matching is case sensitive. All matching occurrences of the
keyword are replaced with the corresponding value.
Default Configuration
The command has no default setting.
Command Mode
Interface Configuration mode
User Guidelines
You can use the macro trace macro-name Interface Configuration command
to apply and show the macros running on an interface or to debug the macro
to find any syntax or configuration errors.
If a command fails because of a syntax error or a configuration error the
macro continues to apply t) in the interface. Use the parameter value

keywords to designate values specific to the interface when creating a macro
that requires the assignment of a unique value.
Keyword matching is case sensitive. All matching occurrences of the keyword
are replaced with the corresponding value. Any full match of a keyword, even
if it is part of a large string, is considered a match and replaced by the
corresponding value.
Some macros might contain keywords that require a parameter value. You can
use the macro apply macro-name command to display a list of any required
values in the macro. If you apply a macro without entering the keyword
values, the commands are invalid and are therefore not applied.
When you apply a macro to an interface, the macro name is automatically
added to the interface. You can display the applied commands and macro
names by using the show running-configuration interface interface-id user
EXEC mode command.
A macro applied to an interface range behaves the same way as a macro
applied to a single interface. When a macro is applied to an interface range, it
is applied sequentially to each interface within the range. If a macro
command fails on one interface, it is nonetheless applied to the remaining
interfaces.
Example
Switch(config) # interface gigabitethernet 1/0/2
Switch(config-if) # macro trace dup
Applying command… ‘duplex full’
Applying command… ‘speed auto’
Switch(config) # interface gigabitethernet 1/0/2
Switch(config-if) # macro apply duplex $DUPLEX full $SPEED auto
Switch(config-if) # exit

When using the ping ipv6 command to check network connectivity of a
directly attached host using its link local address, the egress interface may be
specified in the IPv6Z format. If the egress interface is not specified, the
default interface is selected. Specifying interface zone=0 is equivalent to not
defining an egress interface.
When using the ping ipv6 command with MC address, the information
displayed is taken from all received echo responses.

User Guidelines
The traceroute command works by taking advantage of the error messages
generated by routers when a datagram exceeds its time-to-live (TTL) value.
The traceroute command starts by sending probe datagrams with a TTL
value of one. This causes the first router to discard the probe datagram and
send back an error message. The traceroute command sends several probes at
each TTL level and displays the round-trip time for each.

DELL CONFIDENTIAL – PRELIMINARY 5/15/12 - FOR PROOF ONLY
The traceroute command sends out one probe at a time. Each outgoing
packet can result in one or two error messages. A "time exceeded” error
message indicates that an intermediate router has seen and discarded the
probe. A "destination unreachable" error message indicates that the
destination node has received the probe and discarded it because it could not
deliver the packet. If the timer goes off before a response comes in, the
traceroute command prints an asterisk (*).
The traceroute command terminates when the destination responds, when
the maximum TTL is exceeded, or when the user interrupts the trace with
Esc.
The traceroute command is not relevant to IPv6 link local addresses.
