Introduction
Overview
The NPort S8000 is an industrial device server that integrates a managed Ethernet switch with a fully functional
serial device server. The NPort S8000 device servers are designed to make your industrial serial devices
instantly Internet-ready.
The NPort S8000 offers 2 fiber Ethernet ports, 3 Ethernet ports, and 4 RS-232/422/485 serial ports in a single
device. This not only saves cabinet space and reduces power consumption, but also saves money since you
don’t need to purchase separate switches and serial device servers.
The compact size of the NPort S8000 device servers makes them the ideal choice for connecting
RS-232/422/485 serial devices—such as PLCs, meters, and sensors—to an IP-based Ethernet LAN, making it
possible for your software to access serial devices anywhere over a LAN or the Internet.
The NPort S8000 is a fully equipped managed Ethernet Switch with a suite of useful maintenance and
monitoring functions, and is designed to provide smooth and reliable operation in harsh industrial
environments. It is ideal for keeping automation systems running continuously, sending status reports to help
prevent system damage and losses, and managing your industrial Ethernet networks and serial devices.
Industrial Communications and Automation
As the world’s networking and information technology becomes more complex, Ethernet has become the major
communications interface in many industrial communications and automation applications. In fact, a whole
new industry has sprung up to provide Ethernet products that comply with the requirements of demanding
industrial applications.
Industrial vs. Commercial
Users have found that when transplanting Ethernet from comfortable office environments to harsh and less
predictable industrial environments, commercial Ethernet equipment available in today’s market simply cannot
meet the high reliability requirements demanded by industrial applications. This means that more robust
networking equipment, commonly referred to as industrial Ethernet equipment, is required for these
applications.
Informative vs. Passive
Since industrial Ethernet devices are often located at the endpoints of a system, such devices cannot always
know what’s happening elsewhere on the network. This means that industrial Ethernet communication
equipment that connects these devices must provide system administrators with real-time alarm messages.

NPort S8000 Series
Getting Started
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your NPort S8000.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Please take care when handling the NPort S8000. When plugged in, the NPort S8000’s internal components
generate heat, and consequently the casing may feel hot to the touch.
You should heed the following:
•
Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•
You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•
Keep input wiring and output wiring separate.
•
Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
Connect the 12-48 VDC power line with the NPort S8000’s terminal block. If the power is properly supplied, the
“Ready” LED will show a solid red color until the system is ready, at which time the “Ready” LED will change to
a green color.
Take the following steps to wire the redundant power inputs:
1. Insert the negative/positive DC wires into the V-/V+ terminals.
2. To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp
screws on the front of the terminal block connector.
3. Insert the plastic terminal block connector prongs into the terminal block receptor, which is located on the
S8000’s top panel.

NPort S8000 Series
Getting Started
Connecting to the Network
Connect one end of the Ethernet cable to the NPort S8000’s 10/100M Ethernet port and the other end of the
cable to the Ethernet network. If the cable is properly connected, the NPort S8000 will indicate a valid
connection to the Ethernet in the following ways:
•
The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.
•
The Ethernet LED will flash when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
Connect the serial data cable between the NPort S8000 and the serial device.
LED Indicators

Blinking: The device server has been located by Administrator’s
Location function.
Off
Power is off, or power error condition exists.
Adjustable Pull High/low Resistors and Terminators for the
RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection of serial
signals. When using termination resistors, it is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. Since there is no resistor value that works for every environment, DIP
switches are used to set the pull high/low resistor values for each RS-485 port.
To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in the OFF
position. This is the default setting.
To set the pull high/low resistors to 1 KΩ, make sure both of the assigned DIP switches are in the ON
position.

Wiring the Relay Contact
The NPort 8455I-MM-SChas two sets of relay output—relay 1 and relay 2. Each relay contact consists of two
contacts of the terminal block on the NPort 8455I-MM-SC’s top panel. Refer to the next section for detailed
instructions on how to connect the wires to the terminal block connector, and how to attach the terminal block
connector to the terminal block receptor. The meaning of the two contacts used to connect the relay contacts
is illustrated below.
The fault circuit will open if
1. A relay warning event is triggered,
OR
2. The S8000 is the Master of this Turbo Ring, and the Turbo Ring
is broken,
OR
3. Start-up failure.
If none of these three conditions is met, the fault circuit will remain
closed.
Wiring the Digital Inputs
The NPort 8455I-MM-SC unit has two sets of digital inputs, DI 1 and DI 2. Each DI consists of two contacts of
the 6-pin terminal block connector on the NPort 8455I-MM-SC’s top panel. The remaining contacts are used for
the NPort 8455I-MM-SC’s two DC inputs. Top and front views of one of the terminal block connectors are shown
below.

Initial IP Address Configuration
When setting up the NPort S8000 for the first time, the first thing you should do is configure its IP address. This
chapter introduces the different methods that can be used. The following topics are covered in this chapter:
 Static and Dynamic IP Addresses
 Factory Default IP Address
 Configuration Options
 Web Console
 ARP
 Telnet Console
 Serial Console
NPort S8000 Series
Initial IP Address Configuration
Static and Dynamic IP Addresses
Determine whether your NPort S8000 needs to use a static IP or dynamic IP address (either DHCP or BOOTP
application).
•
If your NPort S8000 is used in a static IP environment, you will assign a specific IP address using one
of the tools described in this chapter.
•
If your NPort S8000 is used in a dynamic IP environment, the IP address will be assigned
automatically from over the network. In this case, set the IP configuration mode to DHCP, BOOTP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your NPort S8000 in the MAC-IP
mapping table when using a DHCP server or BOOTP server. For most applications, you should assign a fixed IP
address to your NPort S8000.
Factory Default IP Address
The NPort S8000 is configured with the following default private IP address:
192.168.127.254
Note that IP addresses that begin with “192.168” are referred to as private IP addresses. Devices configured
with a private IP address are not directly accessible from a public network. For example, you would not be able
to ping a device with a private IP address from an outside Internet connection. If your application requires
sending data over a public network, such as the Internet, your NPort S8000 will need a valid public IP address,
which can be leased from a local ISP.
Configuration Options
Web Console
You may configure your NPort S8000 using a standard web browser. Please refer to chapter 5 and chapter 6,
for details on how to access and use the NPort S8000 web console.
ARP
You may use the ARP (Address Resolution Protocol) command to set up an IP address for your NPort S8000.
The ARP command tells your computer to associate the NPort S8000’s MAC address with an IP address.
Afterwards, use Telnet to access the NPort S8000 and its IP address will be reconfigured.
ATTENTION
In order to use the ARP setup method, both your computer and the NPort S8000 must be connected to the
same LAN. Alternatively, you may use a cross-over Ethernet cable to connect the NPort S8000 directly to your
computer’s Ethernet card. Before executing the ARP command, your NPort S8000 must be configured with the
factory default IP address (192.168.127.254) and your computer and the NPort S8000 must be on the same
subnet.
To use ARP to configure the IP address, complete the following:
1. Obtain a valid IP address for your NPort S8000 from your network administrator.
2. Obtain your NPort S8000’s MAC address from the label on the bottom panel.
3-2
NPort S8000 Series

3. Execute the arp -s command from your computer’s MS-DOS prompt as follows:
arp -s <IP address> <MAC address>
For example,
C:\> arp -s 192.168.200.100 00-90-E8-04-00-11
4. Next, execute a special Telnet command by entering the following exactly:
telnet 192.168.200.100 6000
When you enter this command, a Connect failed message will appear, as shown below.
5. After the NPort S8000 reboots, its IP address will assigned to the new address and you can reconnect using
Telnet to verify that the update was successful.
Telnet Console
Depending on how your computer and network are configured, you may find it convenient to use network
access to set up your NPort S8000’s IP address. This can be done using Telnet.
1. From the Windows desktop, select Start  Run, and type the following in the Run window:
Telnet 192.168.127.254
If your IP address is different from the default setting, use your IP address instead. Click OK.

Choosing the Serial Operation Mode
In this chapter, we describe the various serial operation modes of the NPort S8000. The options include an
operation mode that uses a driver installed on the host computer, and operation modes that rely on TCP/IP
socket programming concepts. After choosing the proper operation mode in this chapter, refer to Chapter 5 for
detailed configuration parameter definitions.
The following topics are covered in this chapter:
 Overview
 Real COM Mode
 RFC2217 Mode
 TCP Server Mode
 TCP Client Mode
 UDP Mode
 Disabled Mode
NPort S8000 Series
Choosing the Serial Operation Mode
Overview
The device server function of the NPort S8000 enables network operation of traditional RS-232/422/485
devices, in which a device server is a tiny computer equipped with a CPU, real-time OS, and TCP/IP protocols
that can bi-directionally translate data between the serial and Ethernet formats. Your computer can access,
manage, and configure remote facilities and equipment over the Internet from anywhere in the world.
Traditional SCADA and data collection systems rely on serial ports (RS-232/422/485) to collect data from
various kinds of instruments. Since the NPort S8000 networks instruments equipped with an RS-232/422/485
communication port, your SCADA and data collection system will be able to access all instruments connected
to a standard TCP/IP network, regardless of whether the devices are used locally or at a remote site.
The NPort S8000 is an external IP-based network device that allows you to expand the number of serial ports
for a host computer on demand. As long as your host computer supports the TCP/IP protocol, you won’t be
limited by the host computer’s bus limitation (such as ISA or PCI), or lack of drivers for various operating
systems.
In addition to providing socket access, the NPort also comes with a Real COM/TTY driver that transmits all serial
signals intact. This means that your existing COM/TTY-based software can be preserved, without needing to
invest in additional software.
Three different Socket Modes are available: TCP Server, TCP Client, and UDP Server/Client. The main
difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient
to send an acknowledgement to the sender. UDP does not require this type of verification, making it possible
to offer speedier delivery. UDP also allows multicasting of data to groups of IP addresses.
Real COM Mode
The NPort S8000 comes equipped with COM drivers that
work with Windows 9x/NT/2000/XP/2003/Vista/2008 (all
x86/x64) systems, and also TTY drivers for Linux and Unix
systems. The driver establishes a transparent connection
between host and serial device by mapping the IP port of
the NPort’s serial port to a local COM/TTY port on the host
computer. This operation mode also supports up to 8
simultaneous connections, so that multiple hosts can
collect data from the same serial device at the same time.
The important point is that Real COM Mode allows users to continue using RS-232/422/485 serial
communications software that was written for pure serial communications applications. The driver intercepts
data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it through the host’s Ethernet
card. At the other end of the connection, the NPort accepts the Ethernet frame, unpacks the TCP/IP packet, and
then transparently sends it to the appropriate serial device attached to one of the NPort’s serial ports.
ATTENTION
Real COM Mode allows several hosts to have access control over the same NPort. The driver that comes with
your NPort controls host access to attached serial devices by checking the host’s IP address.
Modify the Accessible IP Setting table when the legal IP address is required in your application
4-2
NPort S8000 Series
Choosing the Serial Operation Mode
RFC2217 Mode
RFC-2217 mode is similar to Real COM mode. That is, a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the NPort S8000 to a local COM port
on the host computer. RFC2217 defines general COM port control options based on the Telnet protocol. Third
party drivers supporting RFC-2217 are widely available on the Internet and can be used to implement Virtual
COM mapping to your NPort S8000 serial port(s).
TCP Server Mode
In TCP Server mode, the NPort S8000 provides a unique IP port
address on a TCP/IP network. The NPort S8000 waits passively to be
contacted by the host computer, allowing the host computer to
establish a connection with and get data from the serial device. This
operation mode also supports up to 8 simultaneous connections, so
that multiple hosts can collect data from the same serial device—at
the same time.
As illustrated in the figure, data transmission proceeds as follows:
1. The host requests a connection from the NPort configured for
TCP Server Mode.
Once the connection is established, data can be transmitted in both
directions—from the host to the NPort, and from the NPort to the
host.
TCP Client Mode
In TCP Client mode, the NPort S8000 can actively establish
a TCP connection to a pre-defined host computer when
serial data arrives.
After the data has been transferred, the NPort S8000 can
automatically disconnect from the host computer by using
the TCP alive check time or Inactivity time settings.
Refer to chapter 5 for more details.
As illustrated in the figure, data transmission proceeds as
follows:
1. The NPort configured for TCP Client Mode requests a
connection from the host.
2. Once the connection is established, data can be
transmitted in both directions—from the host to the
NPort, and from the NPort to the host.
4-3
NPort S8000 Series
Choosing the Serial Operation Mode
UDP Mode
Compared to TCP communication, UDP is faster and
more efficient. In UDP mode, you can multicast data
from the serial device to multiple host computers,
and the serial device can also receive data from
multiple host computers, making this mode ideal for
message display applications.
Disabled Mode
When the Operation Mode for a particular port is set to Disabled, that port will be disabled.

A subnet mask represents all the network hosts at one geographic location, in one building, or on the same
local area network. When a packet is sent out over the network, the NPort will use the subnet mask to check
whether the desired TCP/IP host specified in the packet is on the local network segment. If the address is on the
same network segment as the NPort, a connection established directly from the NPort. Otherwise, the
connection is established through the given default gateway.

1st DNS Server fails to connect.
When the user wants to visit a particular website, the computer asks a Domain Name System (DNS) server for
the website’s correct IP address, and the computer user the response to connect to the web server. DNS is the
way Internet domain names are identified and translated into IP addresses. A domain name is an alphanumeric
name, such as moxa.com, that is usually easier to remember. A DNS server is a host that translates this kind
of text-based domain name into the numeric IP address used to establish a TCP/IP connection.
In order to use the NPort’s DNS feature, you need to set the IP address of the DNS server to be able to access
the host with the domain name. The NPort provides DNS server 1 and DNS server 2 configuration items to
configure the IP address of the DNS server. DNS Server 2 is included for use when DNS sever 1 is unavailable.
The NPort plays the role of DNS client. Functions that support domain name in the NPort are Time Sever IP
Address, TCP Client-Destination IP Address, Mail Server, SNMP Trap IP Address, and IP Location
Server.
TCP alive check time
Setting
Description
Factory Default
0 to 99 min
This field specifies how long the NPort S8000 will wait for a
7 min
response to “keep alive” packets before closing the TCP
connection. The NPort S8000 checks connection status by
sending periodic “keep alive” packets. If the remote host does
not respond to the packet within the time specified in this field,
the NPort S8000 will force the existing TCP connection to close.
For socket and Real COM Mode, the NPort S8000 will listen for
another TCP connection from another host after closing the
connection. If the TCP alive check time is set to 0, the TCP
connection will remain open and will not send any “keep alive”
packets.
All serial ports use the same TCP live check time in NPort S8000.

this port at the same time. When multiple hosts’ Real COM drivers open the port at the same time, the COM
driver only provides a pure data tunnel—no control capability provided. The serial port parameters will use
firmware settings instead of your application program (AP) settings.
Application software that is based on the COM driver will receive a driver response of “success” when the
software uses any of the Win32 API functions. The firmware will only send data back to the driver on the host.

Data will be sent first-in-first-out when data enters the NPort S8000 from the Ethernet interface.
ATTENTION
When Max connection is set to 2 to 8, this means that the NPort use a “multi connection application” (i.e., 2 to
8 hosts are allowed access to the port at the same time). When using a multi connection application, the NPort
will use the serial communication parameters set in the console. All of the hosts connected to that port must
use the same serial settings. If one of the hosts opens the COM port with parameters that are different from the

0: Disable the force transmit timeout.
1 to 65535: Forces the NPort’s TCP/IP protocol software to try to pack serial data received during the specified
time into the same data frame.
This parameter defines the time interval during which the NPort fetches the serial data from its internal buffer.
If data is incoming through the serial port, the NPort stores the data in the internal buffer. The NPort transmits
data stored in the buffer via TCP/IP, but only if the internal buffer is full or if the force transmit time interval
reaches the time specified under Force Transmit timeout.
Optimal force transmit timeout differs according to your application, but it must be at least larger than one
character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8
data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits,
and the time required to transfer one character is
10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.
Therefore, you should set Force Transmit timeout to be larger than 8.3 ms. Force Transmit timeout is specified
in milliseconds and must be larger than 10 ms.
If the user wants to send the series of characters in a packet, the serial device attached to the NPort should
send characters without time delay larger than Force Transmit timeout between characters and the total length
of data must be smaller than or equal to the NPort’s internal buffer size. The serial communication buffer size

0 ms: TCP connection is not closed due to an idle serial line.
0-65535 ms: The NPort automatically closes the TCP connection if there is no serial data activity for the given
time. After the connection is closed, the NPort starts listening for another host’s TCP connection.
This parameter defines the maintenances status as Closed or Listen on the TCP connection. The connection is
closed if there is no incoming or outgoing data through the serial port during the specific Inactivity time.
If the value of inactivity time is set to 0, the current TCP connection is maintained until there is connection close
request. Although inactivity time is disabled, the NPort will check the connection status between the NPort and
remote host by sending “keep alive” packets periodically. If the remote host does not respond to the packet, it
assumes that the connection was closed down unintentionally. The NPort will then force the existing TCP
connection to close.
ATTENTION
The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent the unintended
loss of data due to the session being disconnected, it is highly recommended that this value is set large enough
so that the intended data transfer is completed.

1
Required
This field is used if you need to receive data from different hosts simultaneously. When set to 1, only one
specific host can access this port of the NPort S8000, and the Real COM driver on that host will have full control
over the port. When set to 2 or greater, up to the specified number of hosts’ Real COM drivers may open this
port at the same time. When multiple hosts’ Real COM drivers open the port at the same time, the COM driver
only provides a pure data tunnel—no control ability. The serial port parameters will use firmware settings
instead of depending on your application program (AP).
Application software that is based on the COM driver will receive a driver response of “success” when the
software uses any of the Win32 API functions. The firmware will only send data back to the driver on the host.
Data will be sent first-in-first-out when data enters the NPort S8000 from the Ethernet interface.
ATTENTION
When Max connection is set to 2 to 8, this means that the NPort will be using a “multi connection application”
(i.e., 2 to 8 hosts are allowed access to the port at the same time). When using a multi connection application,
the NPort will use the serial communication parameters set in the console. All of the hosts connected to that
port must use the same serial settings. If one of the hosts opens the COM port with parameters that are
different from the NPort’s console setting, data communication may not work properly.

Using Serial Traffic Prioritization
The NPort S8000’s traffic prioritization capability provides Quality of Service (QoS) to your network by making
data delivery more reliable. You can prioritize traffic from both serial interface and Ethernet interface on your
network to ensure that high priority data is transmitted with minimum delay.
Traffic can be controlled by a set of rules to obtain the required Quality of Service for your network. The rules
define different types of traffic and specify how each type should be treated as it passes through the NPort
S8000. The NPort S8000 can inspect layer 3 TOS information to each serial port to provide consistent
classification of the entire network. The NPort S8000’s QoS capability improves the performance and
determinism of industrial networks for mission critical applications.
The Serial Traffic Prioritization Concept
What is Traffic Prioritization?
Traffic prioritization allows you to prioritize data so that time-sensitive and system-critical data can be
transferred smoothly and with minimal delay over a network. The benefits of using traffic prioritization are:
•
Improve network performance by controlling a wide variety of traffic and managing congestion.
•
Assign priorities to different categories of traffic. For example, set higher priorities for time-critical or
•
Provide predictable throughput for multimedia applications, such as video conferencing or voice over IP,
business-critical applications.
and minimize traffic delay and jitter.
•
Improve network performance as the amount of traffic grows. This will save cost by reducing the need to
keep adding bandwidth to the network.
DiffServ Code Point (DSCP)
Differentiated Services (DiffServ) Traffic Marking
DiffServ is a Layer 3 marking scheme that uses the DiffServ Code Point (DSCP) field in the IP header to store
the packet priority information. DSCP is an advanced intelligent method of traffic marking as you can choose
how your network prioritizes different types of traffic. DSCP uses 64 values that map to user-defined service

Switch Featured Functions
This chapter explains how to access the NPort S8000’s various configuration, monitoring, and administration
functions. There are three ways to access these functions: RS-232 console, Telnet console, and web browser.
The serial console connection method, which requires using a short serial cable to connect the NPort S8000 to
a PC’s COM port, can be used if you do not know the NPort S8000’s IP address. The Telnet console and web
browser connection methods can be used to access the NPort S8000 over an Ethernet LAN, or over the
Internet.
The Web Console is the most user-friendly way to configure the NPort S8000. In this chapter, we use the Web
Console interface to introduce the functions. There are only a few differences between the Web Console, Serial
Console, and Telnet Console.

Port Trunking
Using Port Trunking
Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation Group. A MAC
client can treat Link Aggregation Groups as if they were a single link.
NPort S8000’s Port Trunking feature allows devices to communicate by aggregating up to 2 trunk groups on the
NPort S8000. If one of the ports fails, the other ports in the same trunk group will provide back up and share
the traffic automatically.
The Port Trunking Concept
Moxa has developed a proprietary Port Trunking protocol that provides the following benefits:
•
Gives you more flexibility in setting up your network connections, since the bandwidth of a link can be
doubled, tripled, or quadrupled.
•
Provides redundancy—if one link is broken, the remaining trunked ports share the traffic within this trunk
group.
•
Load sharing—MAC Client traffic may be distributed across multiple links.
•
To avoid broadcast storms or loops in your network while configuring a trunk, first disable or disconnect all
ports that you want to add to the trunk or remove from the trunk. After you finish configuring the trunk,
enable or re-connect the ports.
If all ports on both switches are configured as 100BASE-TX and they are operating in full duplex, the potential
bandwidth of the connection will be up to 1 Gbps on an NPort S8000- switching device server. This means that
users can connect one NPort S8000 to another NPort S8000 by port trunking to double, triple, or quadruple the
bandwidth of the connection.
When configuring Port Trunking, note that:
Each NPort S8000 can set a maximum of 2 Port Trunking groups (designated Trk1, Trk2).
When you activate Port Trunking settings, some advanced functions that you setup with the original ports will
either be set to factory default values, or disabled:
•
Communication Redundancy will be set to the factory default
•
Traffic Prioritization will be set to the factory default
•

Communication Redundancy
Using Communication Redundancy
Setting up Communication Redundancy on your network helps protect critical links against failure, protects
against network loops, and keeps network downtime at a minimum.
6-4
NPort S8000 Series
Switch Featured Functions
The Communication Redundancy function allows the user to set up redundant loops in the network to provide
a backup data transmission route in the event that a cable is inadvertently disconnected or damaged. This
feature is particularly important for industrial applications, since it could take several minutes to locate the
disconnected or severed cable. For example, if the NPort S8000 is used as a key communications component
of a production line, several minutes of downtime could result in a big loss in production and revenue. The NPort
S8000 supports three different protocols to support this communication redundancy function— Rapid
Spanning Tree/ Spanning Tree Protocol (IEEE 802.1W/1D), Turbo Ring, and Turbo Ring V2.
When configuring a redundant ring, all NPort S8000s on the same ring must be configured to use the same
redundancy protocol. You cannot mix the “Turbo Ring,” “Turbo Ring V2,” and RSTP protocols on the same ring.
The following table lists the key differences between each feature. Use this information to evaluate the benefits
of each, and then determine which features are most suitable for your network.

Most of Moxa’s managed switches now support two proprietary Turbo Ring protocols:
“Turbo Ring” refers to the original version of Moxa’s proprietary redundant ring protocol, which has a recovery
time of under 300 ms.
“Turbo Ring V2” refers to the new generation Turbo Ring, which has a recovery time of under 20 ms.
In this manual, we use the terminology “Turbo Ring” ring and “Turbo Ring V2” ring to differentiate between
rings configured for one or the other of these protocols.
The Turbo Ring Concept
Moxa developed the proprietary Turbo Ring protocol to optimize communication redundancy and achieve a
faster recovery time on the network.
The Turbo Ring and Turbo Ring V2 protocols identify one NPort S8000 as the master of the network, and then
automatically block packets from traveling through any of the network’s redundant loops. In the event that one
branch of the ring gets disconnected from the rest of the network, the protocol automatically readjusts the ring
so that the part of the network that was disconnected can reestablish contact with the rest of the network.
Initial setup of a “Turbo Ring” or “Turbo Ring V2” ring
1. For each NPort S8000 in the ring, select any two ports as the
redundant ports.
2. Connect redundant ports on neighboring NPort S8000 or
switches to form the redundant ring.
The user does not need to configure any of the NPort S8000 or switches as the master to use Turbo Ring or
Turbo Ring V2. If none of the NPort S8000 switches in the ring is configured as the master, then the protocol
will automatically assign master status to one of the switches. In fact, the master is only used to identify which
segment in the redundant ring acts as the backup path. In the following subsections, we explain how the
redundant path is selected for rings configured for Turbo Ring, and Turbo Ring V2.
6-5
NPort S8000 Series
Switch Featured Functions
Determining the Redundant Path of a “Turbo Ring” Ring
In this case, the redundant segment (i.e., the segment that will be blocked during normal operation) is
determined by the number of NPort S8000 that make up the ring, and where the ring master is located.
“Turbo Ring” rings with an even number of NPort S8000
If there are 2N NPort S8000 (an even number) in the
“Turbo Ring” ring, then the backup segment is one of the
two segments connected to the (N+1)st NPort S8000
(i.e., the NPort S8000 unit directly opposite the master).
“Turbo Ring” rings with an odd number of NPort S8000
If there are 2N+1 NPort S8000 (an odd number) in the
“Turbo Ring” ring, with NPort S8000 and segments
labeled counterclockwise, then segment N+1 will serve
as the backup path.
For the example shown here, N=1, so that N+1=2.
Determining the Redundant Path of a “Turbo Ring V2” Ring
For a “Turbo Ring V2” ring, the backup segment is the
segment connected to the 2nd redundant port on the
master.
See Configuring “Turbo Ring V2” in the Configuring
“Turbo Ring” and “Turbo Ring V2” section below.
Ring Coupling Configuration
For some systems, it may not be convenient to connect all devices in the system to create one BIG redundant
ring, since some devices could be located in a remote area. For these systems, “Ring Coupling” can be used to
6-6
NPort S8000 Series
Switch Featured Functions
separate the devices into different smaller redundant rings, but in such a way that they can still communicate
with each other.
ATTENTION
In a VLAN environment, the user must set “Redundant Port,” “Coupling Port,” and “Coupling Control Port” to
join all VLANs, since these ports act as the “backbone” to transmit all packets of different VLANs to different
NPort S8000.
Ring Coupling for a “Turbo Ring” Ring
To configure the Ring Coupling function for a “Turbo Ring” ring, select two NPort S8000 (e.g., Switch A and B
in the above figure) in the ring, and another two NPort S8000 in the adjacent ring (e.g., Switch C and D).
Decide which two ports in each switch are appropriate to be used as coupling ports, and then link them together.
Next, assign one switch (e.g., Switch A) to be the “coupler,” and connect the coupler’s coupling control port
with Switch B (for this example).
The coupler switch (i.e., Switch A) will monitor switch B through the coupling control port to determine whether
or not the coupling port’s backup path should be recovered.
Ring Coupling for a “Turbo Ring V2” Ring
Note that the ring coupling settings for a “Turbo Ring V2” ring are different from a “Turbo Ring” ring. For Turbo
Ring V2, Ring Coupling is enabled by configuring the “Coupling Port (Primary)” on Switch B, and the “Coupling
Port (Backup)” on Switch A only. You do not need to set up a coupling control port, so that a “Turbo Ring V2”
ring does not use a coupling control line.
The “Coupling Port (Backup)” on Switch A is used for the backup path, and connects directly to an extra
network port on Switch C. The “Coupling Port (Primary)” on Switch B monitors the status of the main path, and
connects directly to an extra network port on Switch D. With ring coupling established, Switch A can activate
the backup path as soon as it detects a problem with the main path.

Ring Coupling only needs to be enabled on one of the switches serving as the Ring Coupler. The Coupler must

Dual-Ring Configuration (applies only to “Turbo Ring V2”)
The “dual-ring” option provides another ring coupling configuration, in which two adjacent rings share one
switch. This type of configuration is ideal for applications that have inherent cabling difficulties.

The Turbo Chain Concept
Moxa’s Turbo Chain is an advanced software-technology that gives network administrators the flexibility of
constructing any type of redundant network topology. When using the “chain” concept, you first connect the
Ethernet switches in a chain and then simply link the two ends of the chain to an Ethernet network, as
illustrated in the following figure.
Turbo Chain can be used on industrial networks that have a complex topology. If the industrial network uses a
multi-ring architecture, Turbo Chain can be used to create flexible and scalable topologies with a fast
media-recovery time.

STP/RSTP
The STP/RSTP Concept
Spanning Tree Protocol (STP) was designed to help reduce link failures in a network, and provide protection
from loops. Networks that have a complicated architecture are prone to broadcast storms caused by
unintended loops in the network. The NPort S8000’s STP feature is disabled by default. To be completely
effective, you must enable RSTP/STP on every NPort S8000 connected to your network.
Rapid Spanning Tree Protocol (RSTP) implements the Spanning Tree Algorithm and Protocol defined by IEEE
Std 802.1w-2001. RSTP provides the following benefits:
•
The topology of a bridged network will be determined much more quickly compared to STP.
•
RSTP is backward compatible with STP, making it relatively easy to deploy. For example:
 Defaults to sending 802.1D style BPDUs if packets with this format are received.
 STP (802.1D) and RSTP (802.1w) can operate on different ports of the same NPort S8000. This feature
is particularly helpful when the NPort S8000’s ports connect to older equipment, such as legacy
switches.
You get essentially the same functionality with RSTP and STP. To see how the two systems differ, see the
Differences between RSTP and STP section in this chapter.
NOTE
The STP protocol is part of the IEEE Std 802.1D, 1998 Edition bridge specification. The following explanation
uses bridge instead of switch.
What is STP?
STP (802.1D) is a bridge-based system that is used to implement parallel paths for network traffic. STP uses a
loop-detection process to:
•
Locate and then disable less efficient paths (i.e., paths that have a lower bandwidth).
•
Enable one of the less efficient paths if the most efficient path fails.

The figure below shows a network made up of three LANs separated by three bridges. Each segment uses at
most two paths to communicate with the other segments. Since this configuration can give rise to loops, the
network will overload if STP is NOT enabled.
If STP is enabled, it will detect duplicate paths and prevent, or block, one of them from forwarding traffic. In the
following example, STP determined that traffic from LAN segment 2 to LAN segment 1 should flow through
Bridges C and A because this path has a greater bandwidth and is therefore more efficient.

What happens if a link failure is detected? As shown in next figure, the STP process reconfigures the network
so that traffic from LAN segment 2 flows through Bridge B.
STP will determine which path between each bridged segment is most efficient, and then assigns a specific
reference point on the network. When the most efficient path has been identified, the other paths are blocked.
In the previous 3 figures, STP first determined that the path through Bridge C was the most efficient, and as a
result, blocked the path through Bridge B. After the failure of Bridge C, STP re-evaluated the situation and
opened the path through Bridge B.

How STP Works
When enabled, STP determines the most appropriate path for traffic through a network. The way it does this is
outlined in the sections below.
STP Requirements
Before STP can configure the network, the system must satisfy the following requirements:

Communication between all the bridges. This communication is carried out using Bridge Protocol Data Units
(BPDUs), which are transmitted in packets with a known multicast address.

Each bridge must have a Bridge Identifier that specifies which bridge acts as the central reference point, or
Root Bridge, for the STP system—bridges with a lower Bridge Identifier are more likely to be designated as
the Root Bridge. The Bridge Identifier is calculated using the MAC address of the bridge and a priority
defined for the bridge. The default priority of the NPort S8000 is 32768.

Each port has a cost that specifies the efficiency of each link. The efficiency cost is usually determined by
the bandwidth of the link, with less efficient links assigned a higher cost. The following table shows the
default port costs for a switch:

STP Calculation
The first step of the STP process is to perform calculations. During this stage, each bridge on the network
transmits BPDUs. The following items will be calculated:
•
Which bridge should be the Root Bridge. The Root Bridge is the central reference point from which the

The Root Path Costs for each bridge. This is the cost of the paths from each bridge to the Root Bridge.
•
The identity of each bridge’s Root Port. The Root Port is the port on the bridge that connects to the Root

Bridge via the most efficient path. In other words, the port connected to the Root Bridge via the path with
the lowest Root Path Cost. The Root Bridge, however, does not have a Root Port.
•
The identity of the Designated Bridge for each LAN segment. The Designated Bridge is the bridge with the
lowest Root Path Cost from that segment. If several bridges have the same Root Path Cost, the one with the
lowest Bridge Identifier becomes the Designated Bridge. Traffic transmitted in the direction of the Root
Bridge will flow through the Designated Bridge. The port on this bridge that connects to the segment is
called the Designated Bridge Port.
STP Configuration
After all the bridges on the network agree on the identity of the Root Bridge, and all other relevant parameters
have been established, each bridge is configured to forward traffic only between its Root Port and the
Designated Bridge Ports for the respective network segments. All other ports are blocked, which means that
they will not be allowed to receive or forward traffic.
STP Reconfiguration
Once the network topology has stabilized, each bridge listens for Hello BPDUs transmitted from the Root Bridge
at regular intervals. If a bridge does not receive a Hello BPDU after a certain interval (the Max Age time), the
bridge assumes that the Root Bridge, or a link between itself and the Root Bridge, has gone down. This will
6-16
NPort S8000 Series
Switch Featured Functions
trigger the bridge to reconfigure the network to account for the change. If you have configured an SNMP trap
destination, when the topology of your network changes, the first bridge to detect the change sends out an
SNMP trap.
Differences between RSTP and STP
RSTP is similar to STP, but includes additional information in the BPDUs that allow each bridge to confirm that
it has taken action to prevent loops from forming when it decides to enable a link to a neighboring bridge.
Adjacent bridges connected via point-to-point links will be able to enable a link without waiting to ensure that
all other bridges in the network have had time to react to the change. The main benefit of RSTP is that the
configuration decision is made locally rather than network-wide, allowing RSTP to carry out automatic
configuration and restore a link faster than STP.
STP Example
The LAN shown in the following figure has three segments, with adjacent segments connected using two
possible links. The various STP factors, such as Cost, Root Port, Designated Bridge Port, and Blocked Port are
shown in the figure.
•
Bridge A has been selected as the Root Bridge, since it was determined to have the lowest Bridge Identifier
on the network.
•
Since Bridge A is the Root Bridge, it is also the Designated Bridge for LAN segment 1. Port 1 on Bridge A is
selected as the Designated Bridge Port for LAN Segment 1.
•
Ports 1 of Bridges B, C, X, and Y are all Root Ports sine they are nearest to the Root Bridge, and therefore
have the most efficient path.
•
Bridges B and X offer the same Root Path Cost for LAN segment 2. However, Bridge B was selected as the
Designated Bridge for that segment since it has a lower Bridge Identifier. Port 2 on Bridge B is selected as
the Designated Bridge Port for LAN Segment 2.
•
Bridge C is the Designated Bridge for LAN segment 3, because it has the lowest Root Path Cost for LAN
Segment 3:
 The route through Bridges C and B costs 200 (C to B=100, B to A=100)
 he route through Bridges Y and B costs 300 (Y to B=200, B to A=100)Item 3.3
•
The Designated Bridge Port for LAN Segment 3 is Port 2 on Bridge C.
Using STP on a Network with Multiple VLANs
IEEE Std 802.1D, 1998 Edition, does not take into account VLANs when calculating STP information—the
calculations only depend on the physical connections. Consequently, some network configurations will result in
VLANs being subdivided into a number of isolated sections by the STP system. You must ensure that every
VLAN configuration on your network takes into account the expected STP topology and alternative topologies
that may result from link failures.
The following figure shows an example of a network that contains VLANs 1 and 2. The VLANs are connected
using the 802.1Q-tagged link between Switch B and Switch C. By default, this link has a port cost of 100 and
is automatically blocked because the other Switch-to-Switch connections have a port cost of 36 (18+18). This
means that both VLANs are now subdivided—VLAN 1 on Switch units A and B cannot communicate with VLAN
1 on Switch C, and VLAN 2 on Switch units A and C cannot communicate with VLAN 2 on Switch B.
6-17
NPort S8000 Series
Switch Featured Functions
To avoid subdividing VLANs, all inter-switch connections should be made members of all available 802.1Q
VLANs. This will ensure connectivity at all times. For example, the connections between Switches A and B, and
between Switches A and C should be 802.1Q tagged and carrying VLANs 1 and 2 to ensure connectivity.
See the “Configuring Virtual LANs” section for more information about VLAN Tagging.

Configuration Limits of STP/RSTP
The Spanning Tree Algorithm places limits on three of the configuration items described previously:

These three variables are further restricted by the following two inequalities:
[Eq. 4]:
2 * (Hello Time + 1 sec) ≦ Max. Age ≦ 2 * (Forwarding Delay – 1 sec)
The NPort S8000’s firmware will alert you immediately if any of these restrictions are violated. For example,

Hello Time = 5 sec, Max. Age = 20 sec, and Forwarding Delay = 4 sec does not violate Eqs. 1 through 3, but
does violate Eq. 4, since in this case,
2 * (Hello Time + 1 sec) = 12 sec, and 2 * (Forwarding Delay – 1 sec) = 6 sec.
You can remedy the situation in many ways. One solution is simply to increase the Forwarding Delay value to
at least 11 sec.
HINT: Perform the following steps to avoid guessing:
Step 1: Assign a value to “Hello Time” and then calculate the left most part of Eq. 4 to get the lower limit of
“Max. Age”.
Step 2: Assign a value to “Forwarding Delay” and then calculate the right most part of Eq. 4 to get the upper
limit for “Max. Age”.
Step 3: Assign a value to “Forwarding Delay” that satisfies the conditions in Eq. 3 and Eq. 4.
Bandwidth Management
Using Bandwidth Management
In general, one host should not be allowed to occupy unlimited bandwidth, particularly when the device
malfunctions. For example, so-called “broadcast storms” could be caused by an incorrectly configured topology,
or a malfunctioning device. The NPort S8000 not only prevents broadcast storms, but can also be configured to
a different ingress rate for all packets, giving administrators full control of their limited bandwidth to prevent
undesirable effects caused by unpredictable faults.

Ethernet Traffic Prioritization
Using Traffic Prioritization
The NPort S8000’s traffic prioritization capability provides Quality of Service (QoS) to your network by making
data delivery more reliable. You can prioritize traffic on your network to ensure that high priority data is
transmitted with minimum delay. Traffic can be controlled by a set of rules to obtain the required Quality of
Service for your network. The rules define different types of traffic and specify how each type should be treated
as it passes through the switch. The NPort S8000 can inspect both IEEE 802.1p/1Q layer 2 CoS tags, and even
layer 3 TOS information to provide consistent classification of the entire network. The NPort S8000’s QoS
capability improves the performance and determinism of industrial networks for mission critical applications.

The Traffic Prioritization Concept
What is Traffic Prioritization?
Traffic prioritization allows you to prioritize data so that time-sensitive and system-critical data can be
transferred smoothly and with minimal delay over a network. The benefits of using traffic prioritization are:
•
Improve network performance by controlling a wide variety of traffic and managing congestion.
•
Assign priorities to different categories of traffic. For example, set higher priorities for time-critical or
business-critical applications.
•
Provide predictable throughput for multimedia applications, such as video conferencing or voice over IP,
and minimize traffic delay and jitter.
•
Improve network performance as the amount of traffic grows. This will save cost by reducing the need to
keep adding bandwidth to the network.
How Traffic Prioritization Works
Traffic prioritization uses the four traffic queues that are present in your NPort S8000 to ensure that high
priority traffic is forwarded on a different queue from lower priority traffic. This is what provides Quality of
Service (QoS) to your network.
NPort S8000 traffic prioritization depends on two industry-standard methods:
•
IEEE 802.1D—a layer 2 marking scheme.
•
Differentiated Services (DiffServ)—a layer 3 marking scheme.
IEEE 802.1D Traffic Marking
The IEEE Std 802.1D, 1998 Edition marking scheme, which is an enhancement to IEEE Std 802.1D, enables
Quality of Service on the LAN. Traffic service levels are defined in the IEEE 802.1Q 4-byte tag, which is used to
carry VLAN identification as well as IEEE 802.1p priority information. The 4-byte tag immediately follows the
destination MAC address and Source MAC address.
The IEEE Std 802.1D, 1998 Edition priority marking scheme assigns an IEEE 802.1p priority level between 0
and 7 to each frame. This determines the level of service that that type of traffic should receive. Refer to the
table below for an example of how different traffic types can be mapped to the eight IEEE 802.1p priority levels.

4
Controlled Load (streaming multimedia)
5
Video (interactive media); less than 100 milliseconds of latency and jitter
6
Voice (interactive voice); less than 10 milliseconds of latency and jitter
7
Network Control Reserved traffic
Even though the IEEE 802.1D standard is the most widely used prioritization scheme in the LAN environment,
it still has some restrictions:
•
It requires an additional 4-byte tag in the frame, which is normally optional in Ethernet networks. Without
this tag, the scheme cannot work.
•
The tag is part of the IEEE 802.1Q header, so to implement QoS at layer 2, the entire network must
implement IEEE 802.1Q VLAN tagging.
It is only supported on a LAN and not routed across WAN links, since the IEEE 802.1Q tags are removed when
the packets pass through a router.
6-22
NPort S8000 Series
Switch Featured Functions
Differentiated Services (DiffServ) Traffic Marking
DiffServ is a Layer 3 marking scheme that uses the DiffServ Code Point (DSCP) field in the IP header to store
the packet priority information. DSCP is an advanced intelligent method of traffic marking as you can choose
how your network prioritizes different types of traffic. DSCP uses 64 values that map to user-defined service
levels, allowing you to establish more control over network traffic.
Advantages of DiffServ over IEEE 802.1D are:
•
Configure how you want your switch to treat selected applications and types of traffic by assigning various
grades of network service to them.
•
No extra tags are required in the packet.
•
DSCP uses the IP header of a packet and therefore priority is preserved across the Internet.
•
DSCP is backward compatible with IPV4 TOS, which allows operation with existing devices that use a layer
3 TOS enabled prioritization scheme.
Traffic Prioritization
The NPort S8000 classifies traffic based on layer 2 of the OSI 7 layer model, and the switch prioritizes received
traffic according to the priority information defined in the received packet. Incoming traffic is classified based
upon the IEEE 802.1D frame and is assigned to the appropriate priority queue based on the IEEE 802.1p service
level value defined in that packet. Service level markings (values) are defined in the IEEE 802.1Q 4-byte tag,
and consequently traffic will only contain 802.1p priority markings if the network is configured with VLANs and
VLAN tagging. The traffic flow through the switch is as follows:
1. A packet received by the NPort S8000 may or may not have an 802.1p tag associated with it. If it does not,
then it is given a default 802.1p tag (which is usually 0). Alternatively, the packet may be marked with a
new 802.1p value, which will result in all knowledge of the old 802.1p tag being lost.
2. As the 802.1p priority levels are fixed to the traffic queues, the packet will be placed in the appropriate
priority queue, ready for transmission through the appropriate egress port. When the packet reaches the
head of its queue and is about to be transmitted, the device determines whether or not the egress port is
tagged for that VLAN. If it is, then the new 802.1p tag is used in the extended 802.1D header.
The NPort S8000 will check a packet received at the ingress port for IEEE 802.1D traffic classification, and then
prioritize it based upon the IEEE 802.1p value (service levels) in that tag. It is this 802.1p value that
determines to which traffic queue the packet is mapped.
Traffic Queues
The NPort S8000 hardware has multiple traffic queues that allow packet prioritization to occur. Higher priority
traffic can pass through the NPort S8000 without being delayed by lower priority traffic. As each packet arrives
in the NPort S8000, it passes through any ingress processing (which includes classification,
marking/re-marking), and is then sorted into the appropriate queue. The switch then forwards packets from
each queue.
The NPort S8000 supports two different queuing mechanisms:
•
Weight Fair: This method services all the traffic queues, giving priority to the higher priority queues.
Under most circumstances, this method gives high priority precedence over low-priority, but in the event
that high-priority traffic exceeds the link capacity, lower priority traffic is not blocked.
•
Strict: This method services high traffic queues first; low priority queues are delayed until no more high
priority data needs to be sent. This method always gives precedence to high priority over low-priority.
Configuring Ethernet Traffic Prioritization
Quality of Service (QoS) provides a traffic prioritization capability to ensure that important data is delivered
consistently and predictably. The NPort S8000 can inspect IEEE 802.1p/1Q layer 2 CoS tags, and even layer 3
TOS information, to provide a consistent classification of the entire network. The NPort S8000’s QoS capability
improves your industrial network’s performance and determinism for mission critical applications.

Virtual LAN
Using Virtual LAN
Setting up Virtual LANs (VLANs) on your NPort S8000 increases the efficiency of your network by dividing the
LAN into logical segments, as opposed to physical segments. In general, VLANs are easier to manage.
The Virtual LAN (VLAN) Concept
What is a VLAN?
A VLAN is a group of devices that can be located anywhere on a network, but which communicate as if they are
on the same physical segment. With VLANs, you can segment your network without being restricted by physical
connections—a limitation of traditional network design. As an example, with VLANs you can segment your
network according to:
•
Departmental groups—You could have one VLAN for the Marketing department, another for the Finance
department, and another for the Development department.
•
Hierarchical groups—You could have one VLAN for directors, another for managers, and another for
general staff.
•
Usage groups—You could have one VLAN for e-mail users, and another for multimedia users.

Benefits of VLANs
The main benefit of VLANs is that they provide a network segmentation system that is far more flexible than
traditional networks. Using VLANs also provides you with three other benefits:
•
VLANs ease the relocation of devices on networks: With traditional networks, network administrators
spend most of their time dealing with moves and changes. If users move to a different subnetwork, the
addresses of each host must be updated manually. With a VLAN setup, if a host on VLAN Marketing, for
example, is moved to a port in another part of the network, and retains its original subnet membership, you
only need to specify that the new port is on VLAN Marketing. You do not need to carry out any re-cabling.
•
VLANs provide extra security: Devices within each VLAN can only communicate with other devices on
the same VLAN. If a device on VLAN Marketing needs to communicate with devices on VLAN Finance, the
traffic must pass through a routing device or Layer 3 switch.
•
VLANs help control traffic: With traditional networks, congestion can be caused by broadcast traffic that
is directed to all network devices, regardless of whether or not they need it. VLANs increase the efficiency
of your network because each VLAN can be set up to contain only those devices that need to communicate
with each other.
VLANs and Moxa EtherDevice Switch
Your NPort S8000 provides support for VLANs using IEEE Std 802.1Q-1998. This standard allows traffic from
multiple VLANs to be carried across one physical link. The IEEE Std 802.1Q-1998 standard allows each port on
your NPort S8000 to be placed in:
•
Any one VLAN defined on the NPort S8000.
•
Several VLANs at the same time using 802.1Q tagging.
The standard requires that you define the 802.1Q VLAN ID for each VLAN on your NPort S8000 before the
switch can use it to forward traffic:
Managing a VLAN
A new or initialized NPort S8000 contains a single VLAN—the Default VLAN. This VLAN has the following
definition:
•
VLAN Name—Management VLAN
•
802.1Q VLAN ID—1 (if tagging is required)
All the ports are initially placed on this VLAN, and it is the only VLAN that allows you to access the management
software of the NPort S8000 over the network.

NPort S8000 Series
Switch Featured Functions
Communication Between VLANs
If devices connected to a VLAN need to communicate to devices on a different VLAN, a router or Layer 3
switching device with connections to both VLANs needs to be installed. Communication between VLANs can
only take place if they are all connected to a routing or Layer 3 switching device.
VLANs: Tagged and Untagged Membership
The NPort S8000 supports 802.1Q VLAN tagging, a system that allows traffic for multiple VLANs to be carried
on a single physical (backbone, trunk) link. When setting up VLANs you need to understand when to use
untagged and tagged membership of VLANs. Simply put, if a port is on a single VLAN it can be an untagged
member, but if the port needs to be a member of multiple VLANs, tagged membership must be defined.
A typical host (e.g., clients) will be untagged members of one VLAN, defined as “Access Port” in the NPort
S8000, while inter-switch connections will be tagged members of all VLANs, defined as “Trunk Port” in the
NPort S8000.
The IEEE Std 802.1Q-1998 defines how VLANs operate within an open packet-switched network. An 802.1Q
compliant packet carries additional information that allows a switch to determine which VLAN the port belongs.
If a frame is carrying the additional information, it is known as a tagged frame.
To carry multiple VLANs across a single physical (backbone, trunk) link, each packet must be tagged with a
VLAN identifier so that the switches can identify which packets belong to which VLAN. To communicate between
VLANs, a router must be used.
The NPort S8000 supports two types of VLAN port settings:
•
Access Port: The port connects to a single device that is not tagged. The user must define the default port
PVID that determines to which VLAN the device belongs. Once the ingress packet of this Access Port
egresses to another Trunk Port (the port needs all packets to carry tag information), the NPort S8000 will
insert this PVID into this packet to help the next 802.1Q VLAN switch recognize it.
•
Trunk Port: The port connects to a LAN that consists of untagged devices/tagged devices and/or switches
and hubs. In general, the traffic of the Trunk Port must have a Tag. Users can also assign PVID to a Trunk
Port. The untagged packet on the Trunk Port will be assigned the port default PVID as its VID.
The following section illustrates how to use these ports to set up different applications.

Sample Applications of VLANs using the NPort S8000
In this application:
•
Port 1 connects a single untagged device and assigns it to VLAN 5; it should be configured as “Access Port”
with PVID 5.
•
Port 2 connects a LAN with two untagged devices belonging to VLAN 2. One tagged device with VID 3 and
one tagged device with VID 4. It should be configured as “Trunk Port” with PVID 2 for untagged device and
Fixed VLAN (Tagged) with 3 and 4 for tagged device. Since each port can only have one unique PVID, all
untagged devices on the same port can only belong to the same VLAN.
•
Port 3 connects with another switch. It should be configured as “Trunk Port.” GVRP protocol will be used
through the Trunk Port.
•
Port 4 connects a single untagged device and assigns it to VLAN 2; it should be configured as “Access Port”
with PVID 2.
•
Port 5 connects a single untagged device and assigns it to VLAN 3; it should be configured as “Access Port”
with PVID 3.
•
Port 6 connect a single untagged device and assigns it to VLAN 5; it should be configured as “Access Port”
with PVID 5.
•
Port 7 connects a single untagged device and assigns it to VLAN 4; it should be configured as “Access Port”
with PVID 4.
After proper configuration:
•
Packets from device A will travel through “Trunk Port 3” with tagged VID 5. Switch B will recognize its VLAN,
pass it to port 6, and then remove tags received successfully by device G, and vice versa.
•
Packets from device B and C will travel through “Trunk Port 3” with tagged VID 2. Switch B recognizes its
VLAN, passes it to port 4, and then removes tags received successfully by device F, and vice versa.
•
Packets from device D will travel through “Trunk Port 3” with tagged VID 3. Switch B will recognize its VLAN,
pass to port 5, and then remove tags received successfully by device H. Packets from device H will travel
through “Trunk Port 3” with PVID 3. Switch A will recognize its VLAN and pass it to port 2, but will not
remove tags received successfully by device D.
•
Packets from device E will travel through “Trunk Port 3” with tagged VID 4. Switch B will recognize its VLAN,
pass it to port 7, and then remove tags received successfully by device I. Packets from device I will travel
through “Trunk Port 3” with tagged VID 4. Switch A will recognize its VLAN and pass it to port 2, but will not
remove tags received successfully by device E.

Multicast Filtering
Using Multicast Filtering
Multicast filtering improves the performance of networks that carry multicast traffic. This section explains
multicasts, multicast filtering, and how multicast filtering can be implemented on your NPort S8000.
The Concept of Multicast Filtering
What is an IP Multicast?
A multicast is a packet sent by one host to multiple hosts. Only those hosts that belong to a specific multicast
group will receive the multicast. If the network is set up correctly, a multicast can only be sent to an end-station
6-31
NPort S8000 Series
Switch Featured Functions
or a subset of end-stations on a LAN or VLAN that belong to the multicast group. Multicast group members can
be distributed across multiple subnets, so that multicast transmissions can occur within a campus LAN or over
a WAN. In addition, networks that support IP multicast send only one copy of the desired information across the
network until the delivery path that reaches group members diverges. To make more efficient use of network
bandwidth, it is only at these points that multicast packets are duplicated and forwarded. A multicast packet
has a multicast group address in the destination address field of the packet’s IP header.
Benefits of Multicast
The benefits of using IP multicast are that it:
•
Uses the most efficient, sensible method to deliver the same information to many receivers with only one
transmission.
•
Reduces the load on the source (for example, a server) since it will not need to produce several copies of the
same data.
•
Makes efficient use of network bandwidth and scales well as the number of multicast group members
increases.
•
Works with other IP protocols and services, such as Quality of Service (QoS).
Multicast transmission makes more sense and is more efficient than unicast transmission for some applications.
For example, multicasts are often used for video-conferencing, since high volumes of traffic must be sent to
several end-stations at the same time, but where broadcasting the traffic to all end-stations would cause a
substantial reduction in network performance. Furthermore, several industrial automation protocols, such as
Allen-Bradley, EtherNet/IP, Siemens Profibus, and Foundation Fieldbus HSE (High Speed Ethernet), use
multicast. These industrial Ethernet protocols use publisher/subscriber communications models by
multicasting packets that could flood a network with heavy traffic. IGMP Snooping is used to prune multicast
traffic so that it travels only to those end destinations that require the traffic, reducing the amount of traffic on
the Ethernet LAN.
Multicast Filtering
Multicast filtering ensures that only end-stations that have joined certain groups receive multicast traffic. With
multicast filtering, network devices only forward multicast traffic to the ports that are connected to registered
end-stations. The following two figures illustrate how a network behaves without multicast filtering, and with
multicast filtering.
Network without multicast filtering
All hosts receive the multicast traffic, even if they don’t need it.

NPort S8000 Series
Switch Featured Functions
Network with multicast filtering
Hosts only receive dedicated traffic from other hosts belonging to the same group
Multicast Filtering and Moxa Switching Device Server
The NPort S8000 has three ways to achieve multicast filtering: IGMP (Internet Group Management Protocol)
Snooping, GMRP (GARP Multicast Registration Protocol), and adding a static multicast MAC manually to filter
multicast traffic automatically
IGMP Multicast Filtering
IGMP is used by IP-supporting network devices to register hosts with multicast groups. It can be used on all
LANs and VLANs that contain a multicast capable IP router, and on other network devices that support
multicast filtering. IGMP works as follows:
The IP router (or querier) periodically sends query packets to all end-stations on the LANs or VLANs that are
connected to it. For networks with more than one IP router, the router with the lowest IP address is the querier.
A switch with IP address lower than the IP address of any other IGMP queriers connected to the LAN or VLAN
can become the IGMP querier.
When an IP host receives a query packet, it sends a report packet back that identifies the multicast group that
the end-station would like to join.
When the report packet arrives at a port on a switch with IGMP Snooping enabled, the switch knows that the
port should forward traffic for the multicast group, and then proceeds to forward the packet to the router.
When the router receives the report packet, it registers that the LAN or VLAN requires traffic for the multicast
groups.
When the router forwards traffic for the multicast group to the LAN or VLAN, the switches only forward the
traffic to ports that received a report packet.

NPort S8000 Series
Switch Featured Functions
IGMP (Internet Group Management Protocol)
Snooping Mode
Snooping Mode allows your switch to forward multicast packets only to the appropriate ports. The switch
“snoops” on exchanges between hosts and an IGMP device, such as a router, to find those ports that want to
join a multicast group, and then configures its filters accordingly.
Query Mode
Query mode allows the NPort S8000 to work as the Querier if it has the lowest IP address on the subnetwork
to which it belongs. IGMP querying is enabled by default on the NPort S8000 to help prevent interoperability
issues with some multicast routers that may not follow the lowest IP address election method. Enable query
mode to run multicast sessions on a network that does not contain IGMP routers (or queriers).
NOTE
The NPort S8000 is compatible with any device that conforms to the IGMP v2 and IGMP v3 device protocol.
Configuring IGMP Snooping
IGMP Snooping provides the ability to prune multicast traffic so that it travels only to those end destinations
that require that traffic, thereby reducing the amount of traffic on the Ethernet LAN.

GMRP (GARP Multicast Registration Protocol)
The NPort S8000 supports IEEE 802.1D-1998 GMRP (GARP Multicast Registration Protocol), which differs from
IGMP (Internet Group Management Protocol). GMRP is a MAC-based multicast management protocol, whereas
IGMP is IP-based. GMRP provides a mechanism that allows bridges and end stations to register or de-register
Group membership information dynamically. GMRP functions similarly to GVRP, except that GMRP registers
multicast addresses on ports. When a port receives a GMRP-join message, it will register the multicast
address to its database if the multicast address is not registered, and all the multicast packets with that
multicast address are able to be forwarded from this port. When a port receives a GMRP-leave message, it will
de-register the multicast address from its database, and all the multicast packets with this multicast address
are not able to be forwarded from this port.

Using Set Device IP
To reduce the effort required to set up IP addresses, the NPort S8000 comes equipped with DHCP/BOOTP
server and RARP protocol to set up IP addresses of Ethernet-enabled devices automatically.
When enabled, the Set device IP function allows The NPort S8000 to assign specific IP addresses
automatically to connected devices that are equIPped with DHCP Client or RARP protocol. In effect, the NPort
S8000 acts as a DHCP server by assigning a connected device with a specific IP address stored in its internal
memory. Each time the connected device is switched on or rebooted, the NPort S8000 sends the device the
desired IP address.

The DHCP Relay Agent makes it possible for DHCP broadcast messages to be sent over routers. The DHCP Relay

to a DHCP server. Servers can recognize the Relay Agent Information option and use the information to
implement IP addresses to Clients.
When Option 82 is enabled on the switch, a subscriber device is identified by the switch port through which it
connects to the network (in addition to its MAC address). Multiple hosts on the subscriber LAN can be connected
to the same port on the access switch and are uniquely identified.
The Option 82 information contains 2 sub-options: Circuit ID and Remote ID, which define the relationship
between end device IP and the DHCP Option 82 server. The “Circuit ID” is a 4-byte number generated by the
Ethernet switch—a combination of physical port number and VLAN ID. The format of the “Circuit ID” is as
described below:
FF–VV–VV–PP
Where the first byte “FF” is fixed to “01”, the second and the third byte “VV-VV” is formed by the port VLAN ID
in hex, and the last byte “PP” is formed by the port number in hex. For example,
01–00–0F–03 is the “Circuit ID” of port number 3 with port VLAN ID 15.
The “Remote ID” is to identify the relay agent itself and it can be one of the following:
1. The IP address of the relay agent.
2. The MAC address of the relay agent.
3. A combination of IP address and MAC address of the relay agent.
4. A user-defined string.

Port Access Control
Using Port Access Control
The NPort S8000 provides two kinds of Port-Based Access Controls. One is Static Port Lock and the other is IEEE
802.1X.
Static Port Lock
The NPort S8000 can also be configured to protect static MAC addresses for a specific port. With the Port Lock
function, these locked ports will not learn any additional addresses, but only allow traffic from preset static MAC
addresses, helping to block crackers and careless usage.
IEEE 802.1X
The IEEE 802.1X standard defines a protocol for client/server-based access control and authentication. The
protocol restricts unauthorized clients from connecting to a LAN through ports that are open to the Internet,
and which otherwise would be readily accessible. The purpose of the authentication server is to check each
6-42
NPort S8000 Series
Switch Featured Functions
client that requests access to the port. The client is only allowed access to the port if the client’s permission is
authenticated.
The IEEE 802.1X Concept
Three components are used to create an authentication mechanism based on 802.1X standards:
Client/Supplicant, Authentication Server, and Authenticator.
Supplicant: The end station that requests access to the LAN and switch services and responds to the requests
from the switch.
Authentication server: The server that performs the actual authentication of the supplicant.
Authenticator: Edge switch or wireless access point that acts as a proxy between the supplicant and the
authentication server, requesting identity information from the supplicant, verifying the information with the
authentication server, and relaying a response to the supplicant.
The NPort S8000 acts as an authenticator in the 802.1X environment. A supplicant and an authenticator
exchange EAPOL (Extensible Authentication Protocol over LAN) frames with each other. We can either use an
external RADIUS server as the authentication server, or implement the authentication server in the NPort
S8000 by using a Local User Database as the authentication look-up table. When we use an external RADIUS
server as the authentication server, the authenticator and the authentication server exchange EAP frames
between each other.
Authentication can be initiated either by the supplicant or the authenticator. When the supplicant initiates the
authentication process, it sends an “EAPOL-Start” frame to the authenticator. When the authenticator initiates
the authentication process or when it receives an “EAPOL Start” frame, it sends an “EAP Request/Identity”
frame to ask for the username of the supplicant. The following actions are described below:
1. When the supplicant receives an “EAP Request/Identity” frame, it sends an “EAP Response/Identity” frame
with its username back to the authenticator.
2. If the RADIUS server is used as the authentication server, the authenticator relays the “EAP
Response/Identity” frame from the supplicant by encapsulating it into a “RADIUS Access-Request” frame
and sends to the RADIUS server. When the authentication server receives the frame, it looks up its
database to check if the username exists. If the username is not present, the authentication server replies
with a “RADIUS Access-Reject” frame to the authenticator if the server is a RADIUS server or just indicates
6-43
NPort S8000 Series
Switch Featured Functions
failure to the authenticator if the Local User Database is used. The authenticator sends an “EAP-Failure”
frame to the supplicant.
3. The RADIUS server sends a “RADIUS Access-Challenge,” which contains an “EAP Request” with an
authentication type to the authenticator to ask for the password from the client. RFC 2284 defines several
EAP authentication types, such as “MD5-Challenge,” “One-Time Password,” and “Generic Token Card.”
Currently, only “MD5-Challenge” is supported. If the Local User Database is used, this step is skipped.
4. The authenticator sends an “EAP Request/MD5-Challenge” frame to the supplicant. If the RADIUS server is
used, the “EAP Request/MD5-Challenge” frame is retrieved directly from the “RADIUS Access-Challenge”
frame.
5. The supplicant responds to the “EAP Request/MD5-Challenge” by sending an “EAP
Response/MD5-Challenge” frame that encapsulates the user’s password using the MD5 hash algorithm.
6. If the RADIUS server is used as the authentication server, the authenticator relays the “EAP
Response/MD5-Challenge” frame from the supplicant by encapsulating it into a “RADIUS Access-Request”
frame along with a “Shared Secret,” which must be the same within the authenticator and the RADIUS
server, and sends the frame to the RADIUS server. The RADIUS server checks against the password with its
database, and replies with “RADIUS Access-Accept” or “RADIUS Access-Reject” to the authenticator. If the
Local User Database is used, the password is checked against its database and indicates success or failure
to the authenticator.
7. The authenticator sends “EAP Success” or “EAP Failure” based on the reply from the authentication server.

Auto Warning Settings
Using Auto Warning
Since industrial Ethernet devices are often located at the endpoints of a system, these devices will not always
know what is happening elsewhere on the network. This means that an industrial Ethernet switch that connects
to these devices must provide system maintainers with real-time alarm messages. Even when control
engineers are out of the control room for an extended period of time, they can still be informed of the status of
devices almost instantaneously when exceptions occur. The NPort S8000 supports different approaches to
warn engineers automatically, such as by using email and relay output. It also supports two digital inputs to
integrate sensors into your system to automate alarms using email and relay output.
On the Event Settings page, you may configure how administrators are notified of certain system, network, and
configuration events. Depending on the event, different options for automatic notification are available, as
shown above. Mail refers to sending an e-mail to a specified address. Trap refers to sending an SNMP Trap.
Configuring E-Mail Alert
The Auto Email Warning function uses e-mail to alert the user when certain user-configured events take place.
Three basic steps are required to set up the Auto Warning function:
1. Configuring Email Event Types
Select the desired Event types from the Console or Web Browser Event type page (a description of each
event type is given later in the Email Alarm Events setting subsection).
2. Configuring Email Settings
To configure the NPort S8000’s email setup from the Console interface or browser interface, enter your Mail
Server IP/Name (IP address or name), Account Name, Account Password, Retype New Password, and the
email address to which warning messages will be sent.
3. Activate your settings and if necessary, test the email
After configuring and activating your NPort S8000’s Event Types and Email Setup, you can use the Test
Email function to see if your e-mail addresses and mail server address have been properly configured.

Configuring SNMP
The NPort S8000 supports SNMP V1/V2c/V3. SNMP V1, and SNMP V2c use a community string match for
authentication, which means that SNMP servers access all objects with read-only or read/write permissions
using the community string public/private (default value). SNMP V3, which requires you to select an
authentication level of MD5 or SHA, is the most secure protocol. You can also enable data encryption to
enhance data security.
SNMP security modes and security levels supported by the NPort S8000 are shown in the following table. Select
the security mode and level that will be used to communicate between the SNMP agent and manager.

Relay Alarm Settings
Configuring Relay Warning
The Auto Relay Warning function uses relay output to alert the user when certain user-configured events take
place. There are two basic steps required to set up the Relay Warning function:
1. Configuring Relay Event Types
Select the desired Event types from the Console or Web Browser Event type page (a description of each
event type is given later in the Relay Alarm Events setting subsection).
2. Activate your settings
After completing the configuration procedure, you will need to activate your NPort S8000’s Relay Event
Types.
Event Types can be divided into two basic groups: System Events and Ethernet Port Events. System Events
are related to the overall function of the NPort S8000, whereas Ethernet Port Events are related to the activity
of a specific port.
The NPort S8000 supports two relay outputs. You can configure which relay output is related to which events.
This helps administrators identify the importance of the different events.
Override relay alarm settings
Select this option to override the relay warning setting temporarily. Releasing the relay output will allow
administrators to fix any problems with the warning condition.

Mirror Port Settings
The Mirror port function can be used to monitor data being transmitted through a specific port. This is done
by setting up another port (the mirror port) to receive the same data being transmitted from, or both to and
from, the port under observation. This allows the network administrator to “sniff” the observed port and thus
keep tabs on network activity.
Perform the following steps to set up the Mirror Port function:
1. Configure the S8000 series’ Mirror Port function from either the Console utility or Web Browser interface.
You will need to configure three settings:
Monitored Port
Select the port number of the port whose network activity will be monitored.
Mirror Port
Select the port number of the port that will be used to monitor the activity of the
monitored port.
Watch Direction
Select one of the following three watch direction options:
•
Input data stream
Select this option to monitor only those data packets coming in through the
S8000 series’ port.
•
Output data stream
Select this option to monitor only those data packets being sent out through the
S8000 series’ port.
•
Bi-directional
Select this option to monitor data packets both coming into, and being sent out
through, the S8000 series’ port.
2. Be sure to activate your settings before exiting.

Turbo Ring DIP Switches
The Turbo Ring DIP Switch page allows users to disable the four DIP switches located on the NPort S8000’s
outer casing. When enabled, the DIP switches can be used to configure basic settings for either the “Turbo Ring”
protocol or “Turbo Ring V2” protocol. A complete description of the settings is given below.
NOTE
The proprietary “Turbo Ring” protocol (recovery time < 300 ms) was developed by Moxa in 2003 to provide
better network reliability and faster recovery time for redundant ring topologies. The “Turbo Ring V2” protocol
(recovery time < 20 ms), which was released in 2007, supports additional redundant ring architectures.
In this manual, we use the terminology “Turbo Ring” ring and “Turbo Ring V2” ring to differentiate between
rings configured for one or the other of these protocols.
For a detailed description of “Turbo Ring” and “Turbo Ring V2,” please refer to the Using Communication

The DIP 1 setting will only be active if DIP 3 is in the ON position. If you set DIP 3 to OFF, then the default Ring
Coupling port will NOT be enabled, even if DIP 1 is ON.
NOTE
The Turbo Ring Ports and Coupling Ports will be added automatically to all VLANs if you set DIP Switch 4 to the
“ON” position.
NOTE
If you do not enable any of the NPort S8000 switches to be the Ring Master, the Turbo Ring protocol will
automatically choose the NPort S8000 with the smallest MAC address range to be the Ring Master. If you
accidentally enable more than one NPort S8000 to be the Ring Master, these NPort S8000 switches will
auto-negotiate to determine which one will be the Ring Master.
NOTE
If you use the browser interface to enable the DIP switches (by un-checking the “Disable the Turbo Ring DIP
switch” checkbox), and then flip DIP switch 4 from ON to OFF, the Ring Ports and Coupling Ports that were
added to all VLANs will be restored to their previous software settings. (For details, please refer to the “Using
Virtual LANs” section of this manual).

NPort S8000 Series
Software Installation/Configuration
Overview
The Documentation & Software CD included with your NPort S8000 is designed to make the installation and
configuration procedure easy and straightforward. This auto-run CD includes NPort Windows Driver Manager
(for COM mapping), NPort Search Utility (to broadcast search for all NPort S8000’s accessible over the network),
the NPort S8000 User’s Manual, and the NPort firmware upgrade utility.
NPort Windows Driver Manager
Installing NPort Windows Driver Manager
NPort Windows Driver Manager is intended for use with NPort S8000 serial ports that are set to Real COM mode.
The software manages the installation of drivers that allow you to map unused COM ports on your PC to serial
ports on the NPort S8000. These drivers are designed for use with Windows 98/ME/2000/XP/2003. When the
drivers are installed and configured, devices that are attached to serial ports on the NPort S8000 will be treated
as if they were attached to your PC’s own COM ports.
1. Click the INSTALL COM Driver button in the NPort Installation CD auto-run window to install the NPort
Windows Driver. Once the installation program starts running, click Yes to proceed.
2. Click Next when the Welcome screen opens, to proceed with the installation.

corresponding to the desired port and then click the Setting icon.
7-8
NPort S8000 Series
Software Installation/Configuration
1. On the Basic Setting window, use the COM Number drop-down list to select a COM number to be
assigned to the NPort S8000’s serial port that is being configured. Select the Auto Enumerating COM
Number for Selected Ports option to automatically assign available COM numbers in sequence to
selected serial ports. Note that ports that are “in use” will be labeled accordingly.
2. Click the Advanced Settings tab to modify Tx Mode, FIFO, and Flash Flush.
Tx Mode
Hi-Performance is the default for Tx mode. After the driver sends data to the NPort S8000, the driver
immediately issues a “Tx Empty” response to the program. Under Classical mode, the driver will not send the
“Tx Empty” response until after confirmation is received from the NPort S8000’s serial port. This causes lower
throughput. Classical mode is recommended if you want to ensure that all data is sent out before further
processing.
7-9
NPort S8000 Series
Software Installation/Configuration
FIFO
If FIFO is Disabled, the NPort S8000 will transmit one byte each time the Tx FIFO becomes empty, and an Rx
interrupt will be generated for each incoming byte. This will result in a faster response and lower throughput.
Network Timeout
You can use this option to prevent blocking if the target NPort is unavailable.
Auto Network Re-Connection
With this option enabled, the driver will repeatedly attempt to re-establish the TCP connection if the NPort
S8000 does not respond to background “check alive” packets.
Return error if network is unavailable
If this option is disabled, the driver will not return any error even when a connection cannot be established to
the NPort S8000. With this option enabled, calling the Win32 Comm function will result in the error return code
“STATUS_NETWORK_UNREACHABLE” when a connection cannot be established to the NPort S8000. This
usually means that your host’s network connection is down, perhaps due to a cable being disconnected.
However, if you can reach other network devices, it may be that the NPort S8000 is not powered on or is
disconnected. Note that Auto Network Re-Connection must be enabled in order to use this function.
Fast Flush (only flushes the local buffer)
For some applications, the user’s program will use the Win32 “PurgeComm()” function before it reads or writes
data. After a program uses this PurgeComm() function, the NPort driver continues to query the NPort’s
firmware several times to make sure no data is queued in the NPort’s firmware buffer, rather than just flushing
the local buffer. This design is used to satisfy some special considerations. However, it may take more time
(about several hundred milliseconds) than a native COM1 due to the additional time spent communicating
across the Ethernet. This is why PurgeComm() works significantly faster with native COM ports on the PC than
with mapped COM ports on the NPort S8000. In order to accommodate other applications that require a faster
response time, the new NPort driver implements a new Fast Flush option. By default, this function is enabled.
If you have disabled Fast Flush and find that COM ports mapped to the NPort S8000 perform markedly slower
than when using a native COM port, try to verify if “PurgeComm()” functions are used in your application. If so,
try enabling the Fast Flush function and see if there is a significant improvement in performance.
3. The Serial Parameters window in the following figure shows the default settings when the NPort S8000 is
powered on. However, the program can redefine the serial parameters to different values after the program
opens the port via Win 32 API.

Linux Real TTY Drivers
Basic Procedures
To map an NPort S8000 serial port to a Linux host’s tty port, follow these instructions:
1. Set up the NPort S8000. After verifying that the IP configuration works and you can access the NPort S8000
(by using ping, telnet, etc.), configure the desired serial port on the NPort S8000 to Real COM mode.
2. Install the Linux Real tty driver files on the host
3. Map the NPort serial port to the host’s tty port
Hardware Setup
Before proceeding with the software installation, make sure you have completed the hardware installation.
Note that the default IP address for the NPort S8000 is 192.168.127.254.
NOTE
After installing the hardware, you must configure the operating mode of the serial port on your NPort S8000 to
Real COM mode.
Installing Linux Real TTY Driver Files
1. Obtain the driver file from the included CD-ROM or the Moxa website, at http://www.moxa.com.
2. Log in to the console as a super user (root).
7-16
NPort S8000 Series
Software Installation/Configuration
3. Execute cd / to go to the root directory.
4. Copy the driver file npreal2xx.tgz to the
/ directory.
5. Execute tar xvfz npreal2xx.tgz to extract all files into the system.
6. Execute /tmp/moxa/mxinst.
For RedHat AS/ES/WS and Fedora Core1, append an extra argument as follows:
# /tmp/moxa/mxinst SP1
The shell script will install the driver files automatically.
7. After installing the driver, you will be able to see several files in the /usr/lib/npreal2/driver folder:
> mxaddsvr
(Add Server, mapping tty port)
> mxdelsvr
(Delete Server, un-mapping tty port)
> mxloadsvr
(Reload Server)
> mxmknod
(Create device node/tty port)
> mxrmnod
(Remove device node/tty port)
> mxuninst
(Remove tty port and driver files)
At this point, you will be ready to map the NPort serial port to the system tty port.
Mapping TTY Ports
Make sure that you set the operation mode of the desired NPort S8000 serial port to Real COM mode. After
logging in as a super user, enter the directory /usr/lib/npreal2/driver and then execute mxaddsvr to map
the target NPort serial port to the host tty ports. The syntax of mxaddsvr is as follows:
mxaddsvr [NPort IP Address] [Total Ports] ([Data port] [Cmd port])
The mxaddsvr command performs the following actions:
1. Modifies npreal2d.cf.
2. Creates tty ports in directory /dev with major & minor number configured in npreal2d.cf.
3. Restarts the driver.
Mapping tty ports automatically
To map tty ports automatically, you may execute mxaddsvr with just the IP address and number of ports, as
in the following example:
# cd /usr/lib/npreal2/driver
# ./mxaddsvr 192.168.3.4 16
In this example, 16 tty ports will be added, all with IP 192.168.3.4, with data ports from 950 to 965and
command ports from 966 to 981.
Mapping tty ports manually
To map tty ports manually, you may execute mxaddsvr and manually specify the data and command ports, as
in the following example:
# cd /usr/lib/npreal2/driver
# ./mxaddsvr 192.168.3.4 16 4001 966
In this example, 16 tty ports will be added, all with IP 192.168.3.4, with data ports from 4001 to 4016 and
command ports from 966 to 981.
Removing Mapped TTY Ports
After logging in as root, enter the directory /usr/lib/npreal2/driver and then execute mxdelsvr to delete
a server. The syntax of mxdelsvr is:
mxdelsvr [IP Address]
7-17
NPort S8000 Series
Software Installation/Configuration
Example:
# cd /usr/lib/npreal2/driver
# ./mxdelsvr 192.168.3.4
The following actions are performed when executing mxdelsvr:
1. Modify npreal2d.cf.
2. Remove the relevant tty ports in directory /dev.
3. Restart the driver.
If the IP address is not provided in the command line, the program will list the installed servers and total ports
on the screen. You will need to choose a server from the list for deletion.
Removing Linux Driver Files
A utility is included that will remove all driver files, mapped tty ports, and unload the driver. To do this, you only
need to enter the directory /usr/lib/npreal2/driver, then execute mxuninst to uninstall the driver. This
program will perform the following actions:
1. Unload the driver.
2. Delete all files and directories in /usr/lib/npreal2
3. Delete directory /usr/lib/npreal2
4. Modify the system initializing script file.
The UNIX Fixed TTY Driver
Installing the UNIX Driver
1. Log in to UNIX and create a directory for the Moxa TTY. To create a directory named /usr/etc, execute the
command:
# mkdir –p /usr/etc
2. Copy moxattyd.tar to the directory you created. If you created the /usr/etc directory above, you would
execute the following commands:
# cp moxattyd.tar /usr/etc
# cd /usr/etc
3. Extract the source files from the tar file by executing the command:
# tar xvf moxattyd.tar
The following files will be extracted:
README.TXT
moxattyd.c
--- source code
moxattyd.cf
--- an empty configuration file
Makefile
VERSION.TXT
--- makefile
--- fixed tty driver version
FAQ.TXT
4. Compile and Link
For SCO UNIX:
# make sco
For UnixWare 7:
# make svr5
For UnixWare 2.1.x, SVR4.2:
# make svr42
7-18
NPort S8000 Series
Software Installation/Configuration
Configuring the UNIX Driver
Modify the configuration:
The configuration used by the moxattyd program is defined in the text file moxattyd.cf, which is in the same
directory that contains the program moxattyd. You may use vi, or any text editor to modify the file, as follows:
ttyp1 192.168.1.1 950
For more configuration information, view the file moxattyd.cf, which contains detailed descriptions of the
various configuration parameters.
NOTE
The “Device Name” depends on the OS. See the Device Naming Rule section in README.TXT for more
information.
To start the moxattyd daemon after system bootup, add an entry into /etc/inittab, with the tty name you
configured in moxattyd.cf, as in the following example:
ts:2:respawn:/usr/etc/moxattyd/moxattyd –t 1
Device naming rule
For UnixWare 7, UnixWare 2.1.x, and SVR4.2, use:
pts/[n]
For all other UNIX operating systems, use:
ttyp[n]
Starting moxattyd
Execute the command init q or reboot your UNIX operating system.
Adding an additional server
1. Modify the text file moxattyd.cf to add an additional server. User may use vi or any text editor to modify
the file. For more configuration information, look at the file moxattyd.cf, which contains detailed
descriptions of the various configuration parameters.
2. Find the process ID (PID) of the program moxattyd.
# ps -ef | grep moxattyd
3. Update configuration of moxattyd program.
# kill -USR1 [PID]
(e.g., if moxattyd PID = 404, kill -USR1 404)
This completes the process of adding an additional server.

Well Known Port Numbers
This appendix is for your reference about the Well Known port numbers that may cause network problem if you
set the NPort into the same port. Refer to RFC 1700 for Well Known port numbers of refer to the following
introduction from the IANA.
The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic
and/or Private Ports.
The Well Known Ports are those from 0 through 1023.
The Registered Ports are those from 1024 through 49151.
The Dynamic and/or Private Ports are those from 49152 through 65535.
The Well Known Ports are assigned by the IANA, and on most systems, can only be used by system processes
or by programs executed by privileged users. The following table shows famous port numbers among the
well-known port numbers. For more details, please visit the IANA website:
