2: Introduction
XPort Pro User Guide 17
Additional Features
Modem Emulation
In modem emulation mode, the XPort Pro can replace dial-up modems. The unit accepts modem
AT commands on the serial port, and then establishes a network connection to the end device,
leveraging network connections and bandwidth to eliminate dedicated modems and phone lines.
Web-Based Configuration and Troubleshooting
Built upon Internet-based standards, the XPort Pro enables you to configure, manage, and
troubleshoot through a browser-based interface accessible anytime from anywhere. All
configuration and troubleshooting options are launched from a web interface. You can access all
functions via a Web browser, for remote access. As a result, you decrease downtime (using the
troubleshooting tools) and implement configuration changes (using the configuration tools).
Command-Line Interface (CLI)
Making the edge-to-enterprise vision a reality, the XPort Pro with the Evolution OS™ uses
industry-standard tools for configuration, communication, and control. For example, the Evolution
OS™ uses a Command Line Interface (CLI) whose syntax is very similar to that used by data
center equipment such as routers and hubs.
VIP Access
Virtual IP Access is the Lantronix technology that solves the access-through-firewall problem. With
VIP Access, the XPort Pro can act as a ManageLinx DSC and provide direct access to your
equipment behind a firewall.
SNMP Management
The XPort Pro supports full SNMP management, making it ideal for applications where device
management and monitoring are critical. These features allow networks with SNMP capabilities to
correctly diagnose and monitor XPort Pro device servers.
XML-Based Architecture and Device Control
XML is a fundamental building block for the future growth of M2M networks. The XPort Pro
supports XML-based configuration setup records that make device configuration transparent to
users and administrators. The XML is easily editable with a standard text or XML editor.
Really Simple Syndication (RSS)
The XPort Pro supports Really Simple Syndication (RSS) for streaming and managing on-line
content. RSS feeds all the configuration changes that occur on the device. An RSS aggregator
then reads (polls) the feed. More powerful than simple email alerts, RSS uses XML as an
underlying Web page transport and adds intelligence to the networked device, while not taxing
already overloaded email systems.

2: Introduction
XPort Pro User Guide 18
Enterprise-Grade Security
Evolution OS™ provides the XPort Pro the highest level of networking security possible. This ‘data
center grade’ protection ensures that each device on the M2M network carries the same level of
security as traditional IT networking equipment in the corporate data center.
With built-in SSH and SSL, secure communications can be established between the serial ports
and the remote end device or application. By protecting the privacy of serial data transmitted
across public networks, users can maintain their existing investment in serial technology, while
taking advantage of the highest data-protection levels possible.
SSH and SSL are able to do the following:
Verify the data received came from the proper source
Validate that the data transferred from the source over the network has not changed when it
arrives at its destination (shared secret and hashing)
Encrypt data to protect it from prying eyes and nefarious individuals
Provide the ability to run popular M2M protocols over a secure SSH or SSL connection
In addition to keeping data safe and accessible, the XPort Pro has robust defenses to hostile
Internet attacks such as denial of service (DoS), which can be used to take down the network.
Moreover, the XPort Pro cannot be used to bring down other devices on the network.
You can use the XPort Pro with the Lantronix Secure Com Port Redirector (SCPR) to encrypt
COM port-based communications between PCs and virtually any electronic device. SCPR is a
Windows application that creates a secure communications path over a network between the
computer and serial-based devices that are traditionally controlled via a COM port. With SCPR
installed at each computer, computers that were formerly “hard-wired” by serial cabling for security
purposes or to accommodate applications that only understood serial data can instead
communicate over an Ethernet network or the Internet.
Terminal Server/Device Management
Remote offices can have routers, PBXs, servers and other networking equipment that require
remote management from the corporate facility. The XPort Pro easily attaches to the serial ports
on a server, Private Branch Exchange (PBX), or other networking equipment to deliver central,
remote monitoring and management capability.
Troubleshooting Capabilities
The XPort Pro offers a comprehensive diagnostic toolset that lets you troubleshoot problems
quickly and easily. Available from the Web Manager, CLI, and XML interfaces, the diagnostic tools
let you:
View critical hardware, memory, MIB-II, buffer pool, and IP socket information.
Perform ping and traceroute operations.
Conduct forward or backup DNS lookup operations.
View all processes currently running on the XPort Pro, including CPU utilization and total stack
space available.

Configuration Methods
After installation, the XPort Pro requires configuration. For the unit to operate correctly on a
network, it must have a unique IP address on the network. There are four basic methods for
logging into the XPort Pro and assigning IP addresses and other configurable settings:
DeviceInstaller: Configure the IP address and related settings and view current settings on the
XPort Pro using a Graphical User Interface (GUI) on a PC attached to a network. See Using
DeviceInstaller (on page 21).
Web Manager: Through a web browser, configure the XPort Pro settings using the Lantronix Web
Manager. See Configuration Using Web Manager (on page 23).
Command Mode: There are two methods for accessing Command Mode (CLI): making a Telnet
connection or connecting a terminal (or a PC running a terminal emulation program) to the unit’s
serial port. (See the XPort Pro Command Reference Guide for instructions and available
commands.)
XML: The XPort Pro supports XML-based configuration and setup records that make device
configuration transparent to users and administrators. XML is easily editable with a standard text
or XML editor. (See the XPort Pro Command Reference Guide for instructions and commands.)
Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address or MAC address. The first three
bytes of the Ethernet address are fixed and read 00-20-4A, identifying the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.
Figure 2-2 Sample Hardware Address
00-20-4A-14-01-18 or 00:20:4A:14:01:18
IP Address
Every device connected to an IP network must have a unique IP address. This address references
the specific unit.
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination and source IP
address, and a destination and source port number. For example, a Telnet server commonly uses
port number 23.
The following is a list of the default server port numbers running on the XPort Pro:
TCP Port 22: SSH Server (Command Mode configuration)
TCP Port 23: Telnet Server (Command Mode configuration)
TCP Port 80: HTTP (Web Manager configuration)
TCP Port 443: HTTPS (Web Manager configuration)
UDP Port 161: SNMP
TCP Port 21: FTP

XPort Pro User Guide 20
UDP Port 69: TFTP
UDP Port 30718: LDP (Lantronix Discovery Protocol) port
TCP/UDP Port 10001: Tunnel 1
Note: Multi-port products include one or more additional supported ports and tunnels
with default sequential numbering. For instance: TCP/UDP Port 10002: Tunnel 2, TCP/
UDP Port 10003: Tunnel 3, etc.
Product Information Label
The product information label on the unit contains the following information about the specific unit:
Bar Code
Product ID (name)
Product Revision
Part Number
