Introduction

The Command Line Interface (CLI) is a network management application operated through an
ASCII terminal without the use of a Graphic User Interface (GUI) driven software application. By
directly entering commands, the user has greater configuration flexibility. The CLI is a basic
command-line interpreter similar to the UNIX C shell.

A switch can be configured and maintained by entering commands from the CLI, which is based
solely on textual input and output with commands being entered by a terminal keyboard and the
output displayed as text via a terminal monitor. The CLI can be accessed from a console terminal
connected to an EIA/TIA-232 port or through a Telnet session.

This guide describes how the Command Line Interface (CLI) is structured, describes the
command syntax, and describes the command functionality.

This guide also provides information for configuring the PowerConnect switch, details the
procedures and provides configuration examples. Basic installation configuration is described in
the

Using the CLI

This chapter describes the basics of entering and editing the Dell PowerConnect 62xx Series
Command Line Interface (CLI) commands and defines the command hierarchy. It also explains
how to activate the CLI and implement its major functions.

Entering and Editing CLI 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

When working with the CLI, the command options are not displayed. The command is not
selected by a menu but is entered manually. To see what commands are available in each mode or
within an Interface Configuration, the CLI provides a method of displaying the available
commands, the command syntax requirements and in some instances parameters required to
complete the command. The standard command to request context-sensitive help is the <?> key.

Two instances where the help information can be displayed are:

History Buffer

Every time a command is entered in the CLI, it is recorded in an internally managed Command
History buffer. Commands are stored in the buffer, which operates on a
basis. These commands can be recalled, reviewed, modified, and reissued. This buffer is not
preserved after switch resets.

Command Completion

CLI can complete partially entered commands when the user presses the <tab> or <space> key.
If a command entered is not complete, is not valid, or if some parameters of the command are not
valid or missing, an error message is displayed to assist in entering the correct command. By
pressing the <tab> key, an incomplete command is changed into a complete command. If the
characters already entered are not enough for the system to identify a single matching command,
the <?>key displays the available commands matching the characters already entered.

Short Form Commands

The CLI supports the short forms of all commands. As long as it is possible to recognize the
entered command unambiguously, the CLI accepts the short form of the command as if the user
typed the full command.

Keyboard Shortcuts

The CLI has a range of keyboard shortcuts to assist in editing the CLI commands. The
command, when used in the User EXEC and Privileged EXEC modes, displays the keyboard short
cuts.

Using the CLI 51

Operating on Multiple Objects (Range)

The CLI allows the user to operate on the set of objects at the same time. The guidelines are as
follows for range operation:

• Operations on objects with four or more instances support the range operation.

• The

• The range may be specified in the following manner:

range

key word is used to identify the range of objects on which to operate.

(#-#) — a range from a particular instance to another instance (inclusive). For example,
1/g1-g10 indicates that the operation applies to the gigabit Ethernet ports 1 to 10 on unit

1.

www.dell.com | support.dell.com

(#, #, #) — a list of non-consecutive instances. For example, (1/g1, 1/g3,1/g5) indicates
that the operation applies to the gigabit Ethernet ports 1, 3, and 5 on unit 1.

(#, #-#, #) — ranges and non-consecutive instances listed together. For example, (1/g1,
1/g3-g5, 1/g7) indicates that the operation applies to the gigabit Ethernet ports 1, 7, and
3 to 5 on unit 1.

NOTE: Each # must be a fully qualified port identifier, that is,

type<unit>/<port_type><port_number>, where unit is 1-12, port_type is g or xg and port_number is
1-24 or 1-48 in the case of port_type g and 1-4 for port_type xg. The following formats are allowed:(#­#,#), (#,#-#,#), (#,#-#,#-#,#). For LAG, use "interface range port-channel 1-18".

• When operating on a range of objects, the CLI implementation hides the parameters
that may not be configured in a range (for example, parameters that must be uniquely
configured for each instance).

• The CLI uses best effort when operating on a list of objects. If the user requests an
operation on a list of objects, the CLI attempts to execute the operation on as many
objects in the list as possible even if failure occurs for some of the items in the list. The
CLI provides the user with a detailed list of all failures, listing the objects and the reasons
for the failures.

• Some parameters must be configured individually for each port or interface.

Command Scripting

The CLI can be used as a programmable management interface. To facilitate this function, any
command line starting with the <!> character is treated as a comment line and ignored by the
CLI. Also, the CLI allows the user to disable session timeouts.

52 Using the CLI

CLI Command Notation Conventions

When entering commands there are certain command-entry notations which apply to all
commands. The following table describes these conventions as they are used in syntax definitions.

Convention Description

[ ] In a command line, square brackets indicate an optional entry.

{ } In a command line inclusive brackets indicate a selection of compulsory

parameters separated by the |character. One option must be selected. For
example:
command either

Italic

<

Enter> Any individual key on the keyboard.

Interface Naming Conventions

The conventions for naming interfaces in CLI commands are as follows:

• Unit#/Interface ID—each interface is identified by the
and then the
second unit.

• Unit#—the unit number is used only in a stacking solution where a number of switches
are stacked to form a virtual switch. In this case, the
identifier within the stack.

• Interface ID—is formed by the interface type followed by the interface number. For
example,
Ethernet port 1 on the first unit within the stack.

• Interface Types—the following interface types are defined.
port (for example,
example, xg2 is the 10 gigabit Ethernet port 2).

Interface ID

2/g10

identifies the gigabit port 10 on the second unit;

. For example,

g2

is the gigabit port 2). xg stands for 10 Gigabit Ethernet port (for

CLI Command Modes

Since the set of CLI commands is very large, the CLI is structured as a command-tree hierarchy,
where related command sets are assigned to command modes for easier access. At each level, only
the commands related to that level are available to the user and only those commands are shown in
the context sensitive help for that level.

Using the CLI 53

In this guide, commands are organized in two separate categories: Data Link Layer commands and
Network Layer commands. The Data Link Layer (Layer 2) describes the logical organization of data
bits transmitted on a particular medium. This layer defines the framing, addressing and
checksumming of Ethernet packets. The Network Layer (Layer 3) describes how a series of
exchanges over various data links can deliver data between any two nodes in a network. This layer
defines the addressing and routing structure of the Internet.

Commands that cause specific actions to be taken immediately by the system and do not directly
affect the system configurations are defined at the top of the command tree. For example,
commands for rebooting the system or for downloading or backing up the system configuration
files are placed at the top of the hierarchy tree.

Commands that result in configuration changes to the switch are grouped in a Configuration sub

www.dell.com | support.dell.com

tree.

There are levels beneath the Configuration mode for further grouping of commands. The system
prompt reflects these sub-Configuration modes.

All the parameters are provided with reasonable defaults where possible.

When starting a session, the initial mode is the User EXEC mode. Only a limited subset of
commands is available in this mode. This level is reserved for tasks that do not change the
configuration. To enter the next level, the Privileged EXEC mode, a password is required.

The Privileged EXEC mode provides access to commands that can not be executed in the User
EXEC mode and permits access to the switch Configuration mode.

The Global Configuration mode manages switch configuration on a global level. For specific
interface configurations, command modes exist at a sub-level.

Entering a <
command mode. A specific command is used to navigate from one command 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 and other specific configuration modes.

User EXEC Mode

After logging into the switch, the user is automatically in the User EXEC command mode unless
the user is defined as a privileged user. In general, the User EXEC commands allow the user to
perform basic tests, and list system information.

The user-level prompt consists of the switch host name followed by the angle bracket (>).

The default host name is Console unless it has been changed using the
Global Configuration mode.

prompt is displayed.

Identifying the Switch and Command Mode from the System Prompt

The system prompt provides the user with the name of the switch (hostname) and identifies the
command mode. The following is a formal description of the system command prompt:

[

device name

[

device name]— is the name of the managed switch, which is typically the user-configured

hostname established by the

[

command mode]—is the current configuration mode and is omitted for the top configuration

levels.

[

object]—indicates specific object or range of objects within the configuration mode.

For example, if the current configuration mode is config-if and the object being operated on is
gigabit ethernet 1 on unit 1, the prompt displays the object type and unit (for example, 1/g1).

[# | >]

symbol indicates that the system is in the User EXEC mode, which is a read-only mode in which
the system does not allow configuration.
