Evolution OS™
2: Overview
The XPort AR features the Lantronix Evolution OS™. Key features of the Evolution OS™ include:
Built-in Web server for configuration and troubleshooting from Web-based browsers
CLI configurability
SNMP management
XML data transport and configurability
Really Simple Syndication (RSS) information feeds
Enterprise-grade security with SSL and SSH
Comprehensive troubleshooting tools
Software Features
Modem Emulation
In modem emulation mode, the XPort AR 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 AR enables configuration, management, and
troubleshooting by using a browser-ba se d inte r fac e accessible anytime from anywhere. All
configuration and troubleshooting options are available via the web interface. You can access all
functions via a Web browser, for remote access. As a result, you de crease downtime (using the
troubleshooting tools) and implement configuration changes (using the configuration tools).
XPort AR User Guide 16
2: Overview
Command-Line Interface (CLI)
Making the edge-to-enterprise vision a reality, the XPort AR with Evolution OS™ uses industrystandard 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.
SNMP Management
The XPort AR 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 AR.
XML-Based Architecture and Device Control
XML is a fundamental building block for the future growth of M2M networks. The XPort AR
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 AR 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 can
be used to monitor many RSS feeds at one time. More powerful than simple email alerts, RSS
uses XML as an underlying Web page transport and adds intelligenc e to the networked device,
while not taxing already overloaded email systems.
Enterprise-Grade Security
Evolution OS™ provides the XPort AR 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.
By protecting the privacy of serial data transmitted across public networks, users can maintain
their existing investment in serial technology, while taking advantage o f the highest data-protection
levels possible.
SSH and SSL can:
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 d ata 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 AR 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 AR cannot be used to bring down other devices on the network.
XPort AR User Guide 17
2: Overview
You can use the XPort AR with the Lantronix Secure Com Port Redirector (SCPR) to encrypt COM
port-based communications between PCs and virtually any electron ic device. SCPR is a Windows
application that creates a secure communications p ath ov er a netwo rk b etween the co mpu ter 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 AR 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.
With the Login Connect Menu feature on the XPort AR, connections to the console ports of the
attached devices as well as Ethernet hosts, such as Unix servers or another XPort AR, can easily
be picked from a user-defined menu. This allows console ports across multiple devices to be
accessed from one XPort AR.
Troubleshooting Capabilities
The XPort AR offers a comprehensive diagnostic toolset that lets you troubleshoot problems
quickly and easily. Available from the Web Manager, CLI, and XML interfaces, th e diagnostic tools
let you:
View critical hardware, memory, MIB-II, buffer pool, and IP socket info rmation.
Perform ping and traceroute operations.
Conduct forward or backup DNS lookup operations.
View all processes currently running on the XPort AR, including CPU utilization and total stack
space available.
Configuration Methods
After installation, the XPort AR 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 AR and assigning IP addresses and other configurable settings:
DeviceInstaller—Configure the IP address and related settings and view current settings on
the XPort AR using a PC GUI attached to a network. See Using DeviceInstaller on page 21.
Web Manager—Use a web browser to configure the XPort AR settings using the Lantro nix
Web Manager. See Configuration Using Web Manager on page 23.
Command Line Interface (CLI)—There are two methods for accessing CLI: making a Telnet
connection or connecting a terminal (or a PC running a terminal emulation program) to the
serial port. Refer to the XPort AR Command Reference for instructions and available
commands.
XML—The XPort AR 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. Refer to the XPort AR Command Reference for instructions and available
commands.
XPort AR User Guide 18
Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address or M AC addre s s. The first thr ee
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 a ssigned to each unit. T he following
sample shows a 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 add ress. 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 nu mber. For example, a Telnet serv er commonly u ses
port number 23.

XPort AR User Guide 29
5: Network Settings
Table 5-1 Network 1 Interface Configuration Fields (continued)
Field Description
DHCP Client Select On or Off. At boot up the XPort AR will attempt to lease an IP address
from a DHCP server and maintain the lease at regular intervals.
Note: Overrides BOOTP, the configured IP address, network mask,
gateway, hostname, and domain.
IP Address Enter the XPort AR static IP address. You may enter it alone, in CIDR format,
or with an explicit mask. The IP address is used if BOOTP and DHCP are
both set to Off. Changing this value requires you to reboot the XPort AR.
Note: When DHCP is enabled, the XPort AR tries to obtain an IP address
from DHCP. If it cannot, AutoIP, a server-less method of selecting the IP
address when the DHCP server is unavailable, assigns an address in the
range of 169.254.xxx.xxx.
Default Gateway Enter the IP address of the router for this network. Or clear the field (appears
as <None>). This address is only used for static IP address configuration.
Hostname Enter the XPort AR hostname. It must begin with a letter, continue with a
sequence of letters, numbers, and/or hyphens, and end with a letter or
number.
Domain Enter the domain name.
DHCP Client ID Enter the ID if the DHCP server uses a DHCP ID. The DHCP server lease
table shows IP addresses and MAC addresses for devices. The lease table
shows the Client ID, in hexadecimal notation, instead of the XPort AR MAC
address.
Primary DNS IP address of the primary name server. This entry is required if you choose to
configure a DNS (Domain Name Server).
Secondary DNS IP address of the secondary DNS.
