EDS-MD Command Reference7
2:Overview
EDS-MD4/8/16 supports three convenient configuration methods: Web Manager, Command Line
Interface (CLI) and Extensible Markup Language (XML). For more info rmation about the Web
Manager, see the EDS-MD User Guide on the Lantronix website.
XML Architecture and Device Control
XML is a fundamental building block for the future gr owth of Machine-to-Machine (M2 M) networks.
EDS-MD4/8/16 supports XML configuration records that make configuring the device server easy
for users and administrators. XML configuration records are easy to edit with a a standard text
editor or an XML editor.
For a brief overview of XML, see Chapter 4: Configuration Using XML. It provides rules on basic
XML syntax, a guide to the specific XML tags used, and a guide to using XML configuration
records.
Command Line Interface
Making the edge-to-enterprise vision a reality, EDS-MD4/8/16 uses industry-standard tools for
configuration, communication, and control. For example, the EDS-MD uses a command line
interface (CLI) whose syntax is very similar to that used by data center equipment such as routers
and hubs.
For details of the CLI, see Chapter 5: Commands and Levels. It provides an index of the CLI
Command Hierarchy with links to the corresponding command details. The CLI provides
commands for configuring, monitoring, and controlling the device server.
EDS-MD Command Reference8
3:Command Line Interface
This chapter describes accessing the EDS-MD4/ 8/16 by usin g Te ln et , SSH, or seria l por ts to
configure the EDS-MD, navigating the Command Line Interface (CLI), typing keyboar d shortcuts,
and moving between the levels.
It contains the following sections:
Configuration Using Telnet
Configuration Using Serial Ports
Navigating the CLI Hierarchy
Using Keyboard Shortcuts and CLI
Understanding the CLI Level Hierarchy
Refer to Chapter 5: Commands and Levels for a complete list of levels, commands, and
descriptions.
Configuration Using Telnet
To access and configure the device server by using a Telnet session over the network, you must
first establish a Telnet connection. You can also establish a Telnet connection by clicking the
Telnet Configuration tab in DeviceInstaller. See the DeviceInstaller Online Help for more
information, available on our website www.lantronix.com/support/downloads
.
To access the EDS-MD by using Telnet, perform the following steps.
1.Click Start > Run. The Run dialog box displays.
2.Type cmd in the dialog box and press OK.
3.Type telnet x.x.x.x (x.x.x.x is the IP address). The EDS-MD is online when the
command prompt (>) displays. You are at the root level of the CLI.
Note:Depending on the level of secu rit y, a pa ssw or d ma y be req u ire d.
Configuration Using Serial Ports
Serial Command Mode
The serial port can be configured to operate in command mode permanently or to be triggered
under specified conditions. See the line <line> Level command description for more
information.
Serial Recovery
Serial Recovery mode will temporarily override the line and tunnel settings for the serial line to
allow configuration changes to be made. The line and tunnel settings will be restored once the
user exits the Serial Recovery mode CLI.
EDS-MD Command Reference9
3: Command Line Interface
To configure the Lantronix device server locally using a serial port:
1. Connect a terminal or a PC running a terminal emulation program to one of the device server's
serial ports.
2. Configure the terminal to the following settings:
4. Press and hold down the exclamation point (!) key.
5.Power on the device. After about 20 seconds, the exclamation point will display on the
terminal or PC screen.
6.Type xyz within 5 seconds to display the CLI prompt.
Navigating the CLI Hierarchy
The CLI is organized into a hierarchy of levels. Each level has a group of commands for a specific
purpose. For example, to configure a setting for the FTP server, one would navigate to the FTP
level, which is under the configuration level.
To move to a different level—Enter the name of the level from within its parent level. For
example, to enter the tunnel level, type tunnel <number> at the enable prompt. This
displays: <enable> tunnel <number>#.
To exit and return to one level higher—Type exit an d press the Enter key. Typing exit at the
login level or the enable level will close the CLI session. If Line - Command Mode is specified
as Always, a new session starts immediately.
To view the current configuration at any lev el—Type show.
To view the list of commands available at the current level—Type the question mar k "?". Items
within < > (e.g. <string>) are required parameters.
To view the available commands and explanations—Type the asterisk ( *).
To view the list of commands available for a partial command—Type the partial command
followed by the question mark "?". For example: <tunnel-1>#echo? displays a list of all
echo commands at the tunnel level.
To view available commands and their explanations for a partial command—Type the partial
command followed by the asterisk (*). For example: <tunnel-1>#echo* displays a list of all
echo commands and descriptions at the tunnel level.
To view the last 20 commands entered at the CLI—Type show history.
EDS-MD Command Reference10
Using Keyboard Shortcuts and CLI
One useful shortcut built into EDS-MD4/8/16 is that the complete text of a comma nd does not
have to be entered to issue a command. Typing just enough characters to uniquely identify a
command, then hitting enter, can be used as a short cut for a command. For example, at the
enable level, "sh" can be used for the "show" command.
Tab Completion is also available using the Tab and Enter keys on the keyboard. Typing the first
few characters of a command, then hitting the Tab key displays the first command that begins with
those characters. Hitting the Tab key again displays the next command that begins with the
original characters typed. You can press Enter to execute the command or you can backspace to
edit any parameters.
The following key combinations are allowed when configuring the device server using the CLI:
Table 3-1 Keyboard Shortcuts
Key CombinationDescription
Ctrl + aPlaces cursor at the beginning of a line
Ctrl + bBackspaces one character
Ctrl + dDeletes one character
Ctrl + ePlaces cursor at the end of the line
Ctrl + fMoves cursor forward one character
Ctrl + kDeletes from the current position to the end of the line
Ctrl + lRedraws the command line
Ctrl + nDisplays the next line in the history
Ctrl + pDisplays the previous line in the history
Ctrl + uDeletes entire line and places cursor at start of prompt
Ctrl + wDeletes one word back
Ctrl + zExits the current CLI level
Esc + bMoves cursor back one word
Esc + fMoves cursor forward one word
3: Command Line Interface
Understanding the CLI Level Hierarchy
The CLI hierarchy is a series of levels. Arranging commands in a hierarchy of levels provides a
way to organize and group similar commands, provide different levels of security, and reduce the
complexity and number commands and options presented to a user at one time.
When you start a command line session, you begin at the login level. This level can be password
protected and provides access to hig h lev el sta tu s, a few diag no stic commands, and the enable
level. Further device information and configuratio n are accessed via the enable level.
The enable level can also be password protected and is the gateway to full configuration and
management of the device server. There are comma nds for gathering and effecting all elements of
device status and configuration, as well as commands that take you to additional levels. For
instance, tunnel specific status and configuration is found under the "tunnel" level, and network
specific status and configuration commands are found under the "configuration" level.

EDS-MD Command Reference13
4:Configuration Using XML
The device server provides an Extensible Markup Language (XML) interface that you can use to
configure device server devices. Every configuration setting that can be issued from the device
server Web Manager and CLI can be specified using XML.
The device server can import and export configuration settings as an XML docu ment known as an
XML Configuration Record (XCR). An XCR can be imported or exported via the CLI, a Web
browser, FTP, or the device server filesystem. An XCR can contain many configuration settings or
just a few. For example, it might change all of the configurable parameters fo r a device server, or it
may only change the baud rate for a single serial line. Using XCRs is a straightforward and flexible
way to manage the configuration of multiple device server devices.
XML Configuration Record Document Type Definition
An XML document type definition (DTD) is a description of the str uct ur e an d cont en t of an XML
document. It verifies that a document is valid. XCRs are exported using the DTD as shown in
Figure 4-1 DTD for XCRs.
Figure 4-1 DTD for XCRs
<!DOCTYPE configrecord [
<!ELEMENT configrecord (configgroup+)>
<!ELEMENT configgroup (configitem+)>
<!ELEMENT configitem (value+)>
<!ELEMENT value (#PCDATA)>
<!ATTLIST configrecord version CDATA #IMPLIED>
<!ATTLIST configgroup name CDATA #IMPLIED>
<!ATTLIST configgroup instance CDATA #IMPLIED>
<!ATTLIST configitem name CDATA #IMPLIED>
<!ATTLIST value name CDATA #IMPLIED>
]>
The device server DTD rules state the following:
The XML document element is a <configrecord> element. This is the root element.
A <configrecord> must have one or more <configgroup> elements and can have a
version attribute.
A <configgroup> must have one or more <configitem> elements and can have name
and instance attributes.
A <configitem> element must have one or more <value> elements and can have a name
attribute.
A <value> element can have only data and can have a name attribute.
The name attribute identifies a group, item, or value. It is always a quoted string.
The instance attribute identifies the specific option, like the serial port number. The "instance"
attribute is always a quoted string.
EDS-MD Command Reference14
Note:
The name for each <configgroup> (specified with the name attribute) is the group
name listed in the Web Manager XCR groups or with the "xcr list" CLI comma nd. Se e
the EDS-MD User Guide for more information about the XCR groups.
An empty or missing <value> element in each present <configgroup> clears the
setting to its default.
Quick Tour of XML Syntax
Declaration
The first line, <?xml version="1.0" standalone="yes"?>, is called the XML declaration.
It is required and indicates the XML version in use (norm ally version 1.0). The remainder of the file
consists of nested XML elements, some of which have attributes and content.
Element Start and End Tags
An element typically consists of two tags: start tag and an end tag that surrounds text and other
elements (element content). The start ta g con sis ts of a na m e su rr ou nd e d by an g le br ackets, for
example <configrecord>. The end tag consists of the same name surrounded by angle
brackets, but with a forward slash preceding the name, for example </configrecord>. The
element content can also contain other "child" elements.
4: Configuration Using XML
Element Attributes
The XML element attributes that are name-value pairs included in the start tag after the element
name. The values must always be quoted, using single or double quotes. Each attribute name
should appear only once in an element.
XML Example shows an XML example which consists of a declaration (first line), nested elements
with attributes and content.
Figure 4-2 XML Example
<?xml version=”1.0” standalone=”yes”?>
<configrecord>
<configgroup name = “serial command mode” instance = “1”>
<configitem name = “mode serial string”>
<value>disable</value>
</configitem>
</configgroup>
</configrecord>
The EDS-MD4/8/16 uses the attributes in the following subsections to label the group
configuration settings.
EDS-MD Command Reference15
Record, Group, Item, and Value Tags
A <configgroup> is a logical grouping of configuration parameters and must contain one or
more <configitem> elements. It must have a na m e attribute and may have an instance attribute.
A <configitem> is a specific grouping of configuration parameters relevant to its parent group.
An item takes the name attribute and must contain one or more value elements. For example, the
line group might have parameters such as baud rate, data bits, and parity.
A value may specify the value of a configuration parameter. It may contain the name attribute. In
this example, a value of 9600 might be specified for baud rate; 7 may be specified for data bits,
and even may be specified for parity.
A name attribute identifies the group, item, or value. It is always quoted (as are all XML attributes).
For example, a group that contains serial port parameters has the name "line".
An instance attribute identifies which of several instances is being addressed. It is always quoted.
For example, the serial port name (in the line configgroup) has the instance "1" to indicate serial
port 1 or "2" to specify serial port 2.
The following figures show examples of XML conf igu ra tio n reco rd s an d th e us e of th e
<configrecord>, <configgroup>, <configitem>, and <value> XML elements.
<?xml version="1.0" standalone="yes"?>
<configgroup name = "telnet">
<configitem name = "state">
<value>enable</value>
</configitem>
<configitem name = "authentication">
<value>disable</value>
</configitem>
</configgroup>
<configgroup name = "ssh">
<configitem name = "state">
<value>enable</value>
</configitem>
</configgroup>
Importing and Exporting an XML Configuration File
An XCR can be imported or exported using the following methods:
Filesystem-XCRs can be saved to the device server file system and imported or accessed as
needed. See Best Practices on page 18 or the Filesystem Browser section in the EDS-MD
User Guide.
EDS-MD Command Reference17
CLI-XCRs can be imported (captured) or exported (dumped) directly to a Telnet, SSH, or
serial line CLI session. Capturing an XCR can be started by pasting a valid XCR directly into
the CLI prompt. EDS-MD4/8/16 immediately processes the configuration record, cha nging any
settings specified. This can be done on any level, including the root. Special tags in the XML
allow for providing root and enable level passwords so that this can also be done at the
password prompt.
Web browser-Web Manager can be used to import and export an XCR to the device server file
system. It can also be used to import an XCR fr om an extern al source such as you r local hard
drive.
FTP-The device server FTP server can export and import XCRs when an FTP get or put
command on the filename (edsmd.xcr for export, edsmd_import.xcr for import; both are under
the pwxcr directory) is requested. On export (FTP get of edsmd.xcr), the FTP server obtains
the current XCR from the EDS-MD and sends it as a file. On import (FTP put of
edsmd_import.xcr), the FTP server processes the file by sending it directly to the XML engine.
In both cases the device server filesystem is not accessed. The files edsmd.xcr and
edsmd_import.xcr are not read from or written to the file system. See FTP in the EDS-MD User Guide.
Best Practices
4: Configuration Using XML
You can import or export an entire XCR, or just a portion of it, by specifying the group name and/or
group instances. In the examples below, import and export operations are performed from the CLI
on the local filesystem and require a XCR on the local filesystem. The Web Manager provide s th e
same functionality.
Caution:Using Microsoft Word to edit and save an XCR will change the format of
the file and make it incompatib le wi t h EDS-MD4/8/1 6. This is t rue even if
the file is saved as Plain Text (.txt) or an XML Docu ment (.xml). Notepa d,
a third party text editor, or a specialized XML editor should be used
instead.
Importing
The following syntax can be used to import configurations from a file:
The first line imports all groups specified in the XML config record named in <file>. Any fil ename is
valid, and the file name and extension are not important.
In the second line:
Instance follows group with a colon (see the third example on the next page).
Multiple groups are separated with a comma.
Any white space requires the list of groups to be quoted.
Only the named groups get imported, even if the XCR contains additional XCR groups.
The following syntax can be used to export configurations to a file on the device server's file
system:
The same guidelines above regarding importing configurations also apply to exporting
configurations. If no groups are specified, then the export command will export all configuration
settings to the file. If instances are specified after the groups, only those group instances are
written. If no instance is specified, all instances of that group are written.
Exporting
The following example exports only the accept mode tunneling settings for line 1 to the file
"tunnel_1.xcr" on the device server filesystem:
xcr export tunnel_1.xcr "tunnel accept:1"
The following example exports only the connect mode tunneling settings for all ports to the file
"tunnel_all.xcr" on the device server filesystem:
xcr export tunnel_all.xcr "tunnel connect"
The following example imports only the settings for line 2 from a XCR named "factory_config.xcr"
on the device server filesystem. If "factory_config.xcr" has other configuration settings, they are
ignored:
xcr import factory_config.xcr "line:2"
The following example imports only line settings for all ports from a configuration record on the
device server filesystem named "foobar.xcr":
xcr import foobar.xcr "line"
To import only disconnect mode tunneling settings for port 1 and serial line settings for port 2 from
an XML configuration record named "production.xcr" that contains these settings (and possibly
more), issue the following command:
The following example exports only accept mode tunneling settings on serial port 1, and line
settings on serial port 2 to a file named tunnel_config_t1_l2.xcr on the device server filesystem.
