Using the CLI
This section describes how to perform various configuration operations
through the Command Line Interface CLI.
It includes the following topics:
•UsingtheCLI
• Accessing the Device Through the CLI
• Retrieving an IP Address
• Security Management and Password Configuration
• Configuring Login Banners
• Startup Menu Procedures
• Software Download
Using the CLI
This section provides some general information for using the CLI.
For a complete description of CLI commands, refer to the
Dell PowerEdge
VRTX 1Gb Switch Module, R1-2401 CLI Reference Guide
.
Command Mode Overview
The CLI is divided into command modes, each with a specific command set.
Entering a question mark at the terminal prompt displays a list of commands
available for that particular command mode.
In each mode, a specific command is used to navigate from one mode to
another.
These modes are described below.
User EXEC Mode
During CLI session initialization, the CLI is in User EXEC mode. Only a
limited subset of commands is available in User EXEC mode. This level is
reserved for tasks that do not change the terminal configuration and is used
to access configuration sub-systems.

12 Using the CLI
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Plasma\GSG\Plasma_UGUsing_CLI.fm
DELL CONFIDENTIAL – PRELIMINARY 3/6/13 - FOR PROOF ONLY
After logging into the device, User EXEC command mode is enabled. The
user-level prompt consists of the host name followed by the angle bracket
(>). For example: console>
NOTE: The default host name is console unless it has been modified during
initial configuration.
The User EXEC commands enable connecting to remote devices, changing
terminal settings on a temporary basis, performing basic tests, and listing
system information.
To list the User EXEC commands, enter a question mark at the command
prompt.
To enter the next level, Privileged EXEC mode, a password is required (if
configured).
Privileged EXEC Mode
Privileged EXEC mode provides access to the device global configuration.
Privileged access can be protected, to prevent unauthorized access and to
secure operating parameters. Passwords are displayed on the screen, and are
case-sensitive.
NOTE: The enable command is only necessary if you login with privilege level less
than 15.
To access and list the Privileged EXEC mode commands:
1
At the prompt type enable and press <Enter> .
2 When a password prompt displays, enter the password and press
<Enter> .
The Privileged EXEC mode prompt displays as the device host name
followed by #. For example:
console#
To list the Privileged EXEC commands, type a question mark at the
command prompt.
To return from Privileged EXEC mode to User EXEC mode, type
disable
and press <Enter> .

The following example illustrates accessing privileged EXEC mode and then
returning to the User EXEC mode:
Use the exit command to return to a previous mode.
To configure the device, enter the next level, Global Configuration mode.
Global Configuration Mode
The Global Configuration mode manages device configuration on a global
level. Global Configuration commands apply to system features, rather than a
specific protocol or interface.
To access Global Configuration mode, at the Privileged EXEC Mode prompt,
type configure and press <Enter>. The Global Configuration mode displays
as the device host name followed by (config) and the pound sign #:
To list the Global Configuration commands, enter a question mark at the
command prompt.
The following example illustrates how to access Global Configuration mode
and return back to the Privileged EXEC mode:
Interface Configuration Mode
The Interface Configuration mode configures the device at the physical
interface level (port, VLAN, or LAG). Interface commands that require
subcommands have another level, called the Subinterface Configuration
mode. A password is not required to access this level.

DELL CONFIDENTIAL – PRELIMINARY 3/6/13 - FOR PROOF ONLY
Accessing the Device Through the CLI
You can manage the device using CLI commands, through the CMC to the
terminal console, or via a Telnet connection.
Through CMC
Insert the device into the chassis and enter the CLI commands upon
receiving a prompt.
Telnet Connection
Telnet is a terminal emulation TCP/IP protocol. RS-232 terminals can be
virtually connected to the local device through a TCP/IP protocol network.
Telnet is an alternative to a local login terminal, where a remote login is
required.
The device supports up to four simultaneous Telnet sessions. All CLI
commands can be used over a Telnet session.
If access is via a Telnet connection, ensure that the device has an IP address
and that software has been downloaded to the device.
To start a Telnet session:
1
Select Start > Run .
The
Run window opens.
2 Ty p e cmd.
The cmd window opens.
3 In the cmd window, type Telnet < IP address > <Enter> .
all When a parameter is required to define a range of ports or
parameters 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.

Plasma\GSG\Plasma_UGUsing_CLI.fm
DELL CONFIDENTIAL – PRELIMINARY 3/6/13 - FOR PROOF ONLY
The Telnet session begins.
Retrieving an IP Address
By default, the switch receives its IP address dynamically via a DHCP server.
You can change the OOB port’s IP, but you cannot delete it. and you can add
another IP address on the In-Band interface (port, port-channel or VLAN).
The In-Band IP address can also be received from the DHCP server.
Receiving an In-Band IP Address from a DHCP Server
When using the DHCP protocol to retrieve an IP address, the device acts as a
DHCP client. When the device is reset, the DHCP command is saved in the
configuration file, but the IP address is not.
To retrieve an IP address from a DHCP server, perform the following steps:
1
Select and connect any port to a DHCP server or to a subnet that has a
DHCP server on it.
2 Type the following commands to use the selected port for receiving the IP
address:
a Assigning dynamic IP Addresses on a port:
b Assigning a dynamic IP Addresses on a VLAN:
The interface receives the IP address automatically.
console# configure
console(config)# interface gi0/1
console(config-if)# ip address dhcp
console# configure
console(config)# interface vlan 1
console(config-if)# ip address dhcp

Using the CLI 17
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Plasma\GSG\Plasma_UGUsing_CLI.fm
DELL CONFIDENTIAL – PRELIMINARY 3/6/13 - FOR PROOF ONLY
3 Type the following to verify the IP address:
When configuring/receiving IP addresses through DHCP and BOOTP (an
older version of DHCP), the configuration received from these servers
includes the IP address and may include the subnet mask and default
gateway.
NOTE: It is not necessary to delete the device configuration to retrieve an IP
address from the DHCP server.
NOTE: When copying configuration files, avoid using a configuration file that
contains an instruction to enable DHCP on an interface that connects to the same
DHCP server, or to one with an identical configuration. In this instance, the device
retrieves the new configuration file and boots from it. The device then enables
DHCP, as instructed in the new configuration file, and the DHCP instructs it to reload
the same file.
NOTE: If you configure a DHCP IP address, this address is dynamically retrieved,
and the ip address dhcp command is saved in the configuration file. In the event of
master failure, the backup will again attempt to retrieve a DHCP address. This could
result in one of the following:
•The same IP address may be assigned.
•A different IP address may be assigned, which could result in loss of
connectivity to the management station.
•The DHCP server may be down, which would result in IP address retrieval
failure, and possible loss of connectivity to the management station.

Security Management and Password
Configuration
System security is handled through the Authentication, Authorization, and
Accounting (AAA) mechanism that manages user access rights, privileges,
and management methods. AAA uses both local and remote user databases.
Data encryption is handled through the SSH mechanism.
Passwords can be configured for the following services:
•Terminal
•Telnet
• SSH
•HTTP
•HTTPS
NOTE: When creating a user name, the default priority is 14, which provides
access but not configuration rights. A priority of 15 must be set to enable access
and configuration rights to the device. Although user names can be assigned
privilege level 15 without a password, it is recommended to always assign a
password. If there is no specified password, privileged users can access the Web
interface with any password.
NOTE: Passwords can be secured by using password management commands to
force aging out of passwords, or expiration of passwords. For more information, see
"Management Security" on page 134.
Initial Configuration and Password Recovery
The system is delivered with a default username/password (root/calvin). If a
user-defined password is lost, a password recovery procedure can be invoked
from the Startup menu. This procedure is applicable for the local terminal
only and enables a single access to the device from the local terminal with no
password entered.
The full mode of password recovery mechanism can be enabled/disabled
through the CLI (service password-recovery command).
This affects password recovery in the following way:
• Enabled: When the password-recovery mechanism is invoked, one-time
access to the device without a password is enabled and all configuration
and user files are retained.

Using the CLI 19
FILE LOCATION: C:\Users\gina\Desktop\Checkout_new\Maintenance Projects\Dell
Plasma\GSG\Plasma_UGUsing_CLI.fm
DELL CONFIDENTIAL – PRELIMINARY 3/6/13 - FOR PROOF ONLY
• Disabled: When the password-recovery mechanism is invoked, one-time
access to the device without a password is stilled enabled, however all
configuration files (startup and backups) are removed and the following
log message is generated to the terminal after boot process completed: “All
configuration and user files were removed”
