General Information
Overview
This user’s manual will help you install and maintain the STRIDE industrial Ethernet switches
and media converters. Installation of these devices is very easy and they will begin to operate as
soon as they are powered up.
Operation
Unlike an Ethernet hub that broadcasts all messages out all ports, these industrial Ethernet
switches will intelligently route Ethernet messages only out the appropriate port. The major
benefits of this are increased bandwidth and speed, reduction or elimination of message
collisions, and deterministic performance when tied with real-time systems.
These industrial Ethernet switches can support 10BaseT (10 Mbps) or 100BaseT (100 Mbps)
on their RJ45 ports. Each of these ports will independently auto-sense the speed and duplex,
mdi/mdix-crossover and polarity allowing you to use patch or crossover cables. Managed
switches include models that support gigabit Ethernet.
Some models include fiber optic ports, or slots that accept SFP fiber optic transceivers.

A. Vertical DIN rail mount.
This mounting option allows for quickest installation and optimal utilization of rail space.
B. Vertical screw to panel mount.
This mounting option gives better shock and vibration resistance.
C. Flat screw to panel mount.
This mounting option offers a low profile orientation in shallow boxes plus the best shock and
vibration resistance. The power connection terminal block is removable for access to the mounting tab.

Important Notes about Thermal Performance
Stride switches with metal cases use an innovative
technique to remove excess heat from the product and
its components. This technique effectively utilizes the
heavy gauge all-aluminum case as a large heat sink.
Therefore, the case may be warm during operation,
especially with heavy loads such as all ports linked and
active. This is normal operation. For best performance,
it is recommended that a DIN rail spacer such as end
clamp, part number DN-EB35, be used between the
switch and any adjacent device. This will leave an air
gap for best heat dissipation off the case.
For best thermal performance when direct panel
mounting to a metal surface, thermal compound may
be used between the switch and mounting surface.
This will reduce any air gaps and optimize the transfer
of heat from the case to the mounting surface.

Power and Alarm Wiring
Single DC Power
Redundant DC Power
Single DC Power Redundant DC Power
Overview
DC voltage in the range of 10 to 30 VDC (3.0W) needs to be applied between the P1 (plus)
terminal and the Minus terminal as shown below. To maintain a UL 508 panel listing use a
Class 2 power supply. The chassis screw terminal should be tied to panel or chassis ground. To
reduce down time resulting from power loss, these industrial Ethernet switches can be powered
redundantly with a second power supply as shown below.
NOTE: When powering multiple switches from a common power supply, it is most reliable to power the switches
sequentially rather than simultaneously. The characteristics of the power supply and the significant startup current of the
switches may result in an error in booting the switches when powered simultaneously.
Screw Torque
When tightening the screws be careful to tighten to a max. torque of 5 lb-in [0.57 Nm]. Wire
size should be between 24 AWG and 12 AWG.
Before performing any wiring to these switches make sure...
• The area is currently nonhazardous (especially when working in Class 1, Div 2 or Zone 2
hazardous locations).
• Power is off to the switch
• The screw terminal block is unplugged. This is especially important on the aluminum housed
units as shown below. Connecting or disconnecting wires to the screw block when its in place
and power is turned on can allow the screwdriver to short the power to the case

Communication Ports Wiring
Overview
The industrial Ethernet switches and media converters provide connections to standard
Ethernet devices such as PLCs, Ethernet I/O, industrial computers and much more. RJ45
(copper) Ethernet ports and fiber optic Ethernet ports are available depending on model.
RJ45 Ethernet Wiring
Use data-quality (not voice-quality) twisted pair cable rated category 5e (or better) with
standard RJ45 connectors. Straight-through or crossover Ethernet cable can be used for all
devices the switch is connected to because all the ports are capable of auto-mdi/mdix-crossover
detection.
The RJ45 Ethernet port connector bodies on these products are metallic and connected to the
Chassis GND terminal. Therefore, shielded cables may be used to provide further protection.
To prevent ground loops, the cable shield should be tied to the metal connector body at one
end of the cable only. Electrical isolation is also provided on the Ethernet ports for increased
reliability.

Ethernet Fiber Wiring Guidelines
Depending on the model these industrial Ethernet switches may include one, two or four
fiber optic ports. All 100 Mbps fiber ports are available with dual SC or ST multimode style
connectors. Refer to the technical specifications for details.
All 1000 Mbps fiber ports are provided as SFP (small form pluggable). These accept plug-in
fiber transceivers that have an LC style connector. They are available with either multimode
or singlemode transceivers. Refer to the technical specifications for details.
For each fiber port there is a transmit (TX) and receive (RX) signal. When making your
fiber optic connections, make sure that the transmit (TX) port of the switch connects to the
receive (RX) port of the other device, and the receive (RX) port of the switch connects to the
transmit (TX) port of the other device.
Use standard fiber optic wiring techniques (not covered by this manual) to make your
connections. The corresponding ACT/LNK LED will be ON solid or flashing when you
have made a proper connection.
Fiber Ports on Switches
1-28
Fiber Ports on Media Converters
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. B
Chapter 1 - Hardware
Duplex Operation
The RJ45 ports will auto-sense for Full or Half duplex operation; the fiber ports are configured
for full duplex operation. On managed switches the duplex setting is software configurable.
NOTE: Fiber devices with half duplex settings will communicate with the switch in most situations.
Network Device Check
The industrial Ethernet switches and media converters support 10/100BaseT or 10/100/100
Base T on the RJ45 (copper) ports and 100BaseFX or gigabit Ethernet on the fiber optic ports
depending on model. Make sure you connect the appropriate devices to each port.
NOTE: The following AutomationDirect PLC Ethernet Modules are not compatible with the Stride Ethernet switches
and Media Converters with fiber optic connections because the modules have a speed of 10BaseF (fiber optic) only:
Ethernet Communications Module, p/n H2-ECOM-F & H4-ECOM-F; Ethernet Base Controller Module, p/n H2-EBC-F &
H4-EBC-F; Ethernet Remote Master Module, p/n H2-ERM-F & H4-ERM-F.
Verifying Connectivity
After all Ethernet and/or fiber connections are made, check the LEDs corresponding to the
ports that each of the devices are connected to. Ensure that for each port that is in use, the LED
is on or blinking. If a port LED is off, go back and check for connectivity problems between
that port and the network device connected to that port. In addition, the color of the LED
should indicate the speed at which your device is connected (see prior section on LEDs).
Serial Console Port Wiring
An optional way to configure the managed switch is through the RJ45 console RS232 port.
Wire a serial console cable as shown below to make a connection between a COM port on your
PC (DB9 male) and the RS232 port of the managed switch (RJ45 female).

Chapter 2 - Managed Switch Quick Start
Connecting to the Switch for the first time
Connecting to the switch over Ethernet:
NOTE: See Setting up PC for USB connection to Switch later in this chapter for the option of using USB for switch
connection.
Connecting to the switch for the first time over Ethernet requires no extra tools or driver
installation and is, therefore, the recommended way to accomplish this.
The default IP address and subnet mask of the switch is 192.168.0.1 and 255.255.255.0.
This means that your PC’s network interface card (NIC) that is connected to the switch
must be set to a compatible IP address and subnet mask to access the web-based switch
configuration tool. It is recommended that you connect your PC directly to the switch for
the initial setup of the network settings. An example IP address and subnet mask to set your
PC’s network interface to is 192.168.0.100 and 255.255.255.0.
1. Go to the Start Button and click on “Run” (if you do not see a “Run” option, type Run in the
search box and hit Enter). Type in ncpa.cpl and hit OK.

2. Right click on the Network Interface that is connected to your switch and choose Properties.
3. Scroll down and highlight the “Internet Protocol Version 4 (TCP/IPv4)” selection and click on the
Properties button.
4. Write down the current settings so that you may put them back in after configuring the Network
settings of the switch to a compatible setup for your environment.
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. B

Chapter 2 - Managed Switch Quick Start
5. Type in the IP address and subnet mask of 192.168.0.100 and 255.255.255.0 or another
compatible IP address and subnet mask. Click on the OK button. Click on the OK button for
the Network Interface Properties window and close the Network Connections window.
NOTE: Neither the Network Address nor the Broadcast Address for you subnet are valid host addresses. For our
example that has a Subnet Mask or 255.255.255.0 and the first three octets are 192.168.0, neither the pc nor the switch
are permitted to be assigned 192.168.0.0 or 192.168.0.255 as an IP address.
2-4
6. Open up your web browser program such as Internet Explorer, Mozilla Firefox or other and type
in 192.168.0.1 in the URL line.
7. Enter in admin for the User name and admin for the password and click on OK.

9. Click on the “Quick Setup” link on the upper left hand side of the window to access the Network
Settings.
10. Enter in the desired IP address and subnet mask that is compatible with the network that the
switch will go on or enable DHCP if that is the method you choose to assign the network
settings. Click on the “Commit Changes” button to enable the new settings.
2-6
NOTE: Neither the Network Address nor the Broadcast Address for you subnet are valid host addresses. For our
example that has a Subnet Mask or 255.255.255.0 and the first three octets are 192.168.0, neither the pc nor the switch
are permitted to be assigned 192.168.0.0 or 192.168.0.255 as an IP address.

Chapter 2 - Managed Switch Quick Start
11. Return to steps 1 – 4 to put in the original network settings for your PC.
12. Connect your PC and the switch to the network and enter in the new IP address into your web
browser URL to access the switch. If you chose DHCP as the method for assigning the network
settings to your switch, you will need to contact the network administrator to see which IP
address has been assigned to the switch or connect via USB or serial (explained further down in
this document) to ascertain what the IP address is on the switch.
13. Now that you can access the switch, you may begin to configure the switch with the settings
appropriate for your network. If you are unsure of where to start with the configuration, go
the section titled, “Why do you need a managed switch?” to understand more about the Stride
managed switch, its capabilities and how these features can be used. Note that the default
settings enable RSTP and IGMP which will be adequate for many networks with no further
configuration.
Setting up PC for USB connection to switch:
This method can be used to initially configure the switch settings. It may also be needed
if the switch has been previously configured and the network settings are unknown. If the
switch has been set to DHCP, this method can be used to ascertain the current IP address
that has been assigned to the switch by the DHCP server.
Three things will be required in order to connect to the switch via the USB port:
1. USB driver: This can be obtained from www.automationdirect.com. Download the executable and
run it to install the driver.
2. Cable: The cable required is a Male-A connector (plugs into PC) to Male Mini B-type (5 pin)
connector (plugs into switch).
3. Terminal software tool: Hyperterminal used to come pre-installed in Windows until Windows
Vista and 7 were released. TeraTerm is another tool that can be downloaded and installed for free.
After the USB driver EXE file has been downloaded and run, plug the USB cable into the PC
and switch.
Windows will install the driver. If the New Hardware Wizard appears, select the “No, not
this time” selection and click Next. On the following screen, select the “Install Software
automatically” option and click Next. Once the driver is loaded, you may get prompted by
a window that says the driver has not been verified by Windows. Click on the “Continue
Anyway” button to complete the installation.

Chapter 2 - Managed Switch Quick Start
Why might you need a Managed Switch?
Enhanced traffic filtering:
An unmanaged switch will filter out many packets from an end device that a hub would not
but there are still many types of packets that an unmanaged switch cannot determine what
to do with and must forward on to all ports. Whenever a device receives a packet that is not
specifically targeted to that device, there is a certain amount of processing time that takes
away from other important tasks that the device may really need to be spending time on.
These ‘unintentional’ packets also get in the way of the packets that are intended for that
device. This hurts the determinism of a process. A managed switch can help with this in
several different ways:
• Multicast Filtering (IGMP): It is common in a control system to see a large amount of Multicast
packets. These packets cannot be filtered out by an unmanaged switch. The Stride managed switch
can intelligently ‘learn’ whether certain Multicast packets should be sent to the devices on its ports
and will filter them or not filter them appropriately.
• VLANs: A VLAN is a logical way to separate networks in ways that used to require physical
separation. Because of existing network infrastructure or for ease of wiring (and reduced cost), it
may be difficult to physically separate networks that need separation due to the type of packets that
are on them. Setting up VLANs can simplify the setup for these situations.
• Traffic Priority (QoS/CoS): Some traffic may be more important to a specific device than other
traffic. Using the Quality of Service feature, the Stride switch can apply tags to a packet coming
into the switch to give that packet a higher priority going to another switch. The last switch will
then remove the tag before sending the packet to the device. It can also use the tags applied to the
packets by the devices themselves if they support this.
2-16
Troubleshooting:
As Ethernet messaging becomes more of the standard for communications between devices
in a control system, it may become more necessary to gain visibility to these types of
communications. With hubs, it was possible to see the messages between devices because
hubs broadcast every packet to all ports. Unmanaged switches took away this capability as
they filter unicast packets to only the intended physical ports. Managed switches can help
with this by utilizing the Port Mirroring feature. The Stride managed switch can also give
you visibility in to the type of packets that are being sent across the switch by viewing the
Network Statistics page in the configuration.
• Port Mirroring: With the Port Mirroring feature you simply specify which ports’ data you want to
view and where to send that data. Plug your PC into that port and use Ethernet sniffing software
(such as Wireshark) and you can now see the data being sent back and forth.
• Network Statistics: By looking at what kind of packets that are coming in and out of the switch,
you can determine what action needs to be taken to make your network work better. If you see a
lot of Multicast traffic, utilize the Multicast Filtering feature. If there are lots of broken packets,
troubleshoot the wiring to determine where the problem lies.
Redundancy:
The downside of any Ethernet switch is the simple fact that it is another electronic
component in the system that could be subject to failure. There is also the risk that as a
network grows and more switches are added to it, a ‘ring’ may accidentally be created causing
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. B
Chapter 2 - Managed Switch Quick Start
the network to go down. Utilizing the Spanning Tree and/or Real-Time Ring feature of the
Stride managed switch can reduce these risks.
• STP: The Spanning Tree protocol simply allows you to purposely create a ring that allows for
multiple, redundant paths on the network but intelligently decides one path when the network
comes up and assigns alternate paths if some part of the original path goes down.
• RSTP: The Rapid Spanning Tree Protocol is the preferred method in the industry today as the
manner in which it decides the original paths and the time in which it changes over to alternate
paths is much, much faster than the original Spanning Tree Protocol. It is really only useful to
enable the older STP if your legacy network requires this protocol. The RSTP feature is enabled by
default.
• Real-Time Ring: In many Control Systems, the time it takes for the RSTP algorithm to change
paths upon some network event is too slow. The Real-Time Ring is proprietary to the Stride
managed switches but it has the advantage of changing paths very, very quickly.
Security:
Network security has become a great concern for facilities these days. And while the network
devices themselves are only one part of a network security strategy, the Stride managed
switches have several security features:
• Port Control: In the “Port Settings” setup, you can disable ports that are not being used. This can
limit unauthorized access.
• Security Settings: There are several different methods of enabling security in the switch. There
are security methods to prevent access to the switch (Remote Access Security), you can determine
which devices can connect to the switch (Port Security MAC Entries) and you can enable
encryption for data going between switches (IPsec).
• Remote Access Security: You can disable access to the switch or implement secure pass-wording in
order to access the switch.
• IPsec: There are many different methods that can be employed to encrypt the data going to
or from the switch. The particular method (encryption protocol/algorithm) will most likely be
determined by your network administrator.

Chapter 2 - Managed Switch Quick Start
Better Network ‘Awareness’:
The ability of the process to know when something is wrong with the network and what
is wrong with the network is a great feature of the Stride managed switches. Your PLC or
controlling device can make ‘smarter’ decisions as to what alarms or fallback behavior to
trigger based upon the different diagnostic data that is supplied by the switch.
• Modbus Stats: If you have a controlling device on the network that has Modbus TCP or UDP
client capability, there are several diagnostic tags that can be read from the switch to indicate the
health of the network.
• SNMP: SNMP stands for Simple Network Management Protocol and is used for just that. There
are many software tools out there that can query or receive ‘traps’ sent by the Stride managed switch
to ascertain events or health of the switch.
• Port and Power Status (Alarm Output): The Stride managed switch has two power inputs that
can be used for redundancy. If one of the power inputs fails, there is a relay contact that can be
configured to report this failure.
• Spanning Tree Status: The switch can be configured to report when something in the Spanning
Tree has changed.
• Real-Time Ring Status: The Real-Time Ring status can be ascertained from other devices as well.
• MAC Table: The switch keeps a table of the MAC IDs of devices that are communicating on it

System Information
The System Information screen simply provides the information shown below. The screen is
updated every five seconds.
3-2
Model: This field shows the model number of this particular switch. It is set by the factory
and cannot be changed.
Description: This field displays more descriptive information about this particular switch
model. It is also set by the factory and is not changeable. This data is available via SNMP as
SYSTEM.SYSDESCR.0.
System Name: This field is configured by the user with the appropriate text for their
application. It is configured in the “System Settings” tab under the Main Settings section.
This field is also used as the hostname of the switch and, therefore, must contain only digits,
dashes and letters. It is also available via SNMP as SYSTEM.SYSNAME.0.
Switch Location: This field is configured by the user with the appropriate text for their
application. It is configured in the “System Settings” tab under the Main Settings section.
This data is available via SNMP as SYSTEM.SYSLOCATION.0.
Contact: This field is configured by the user with the appropriate text for their application.
It is configured in the “System Settings” tab under the Main Settings section. This data is
available via SNMP as SYSTEM.SYSCONTACT.0.
IPv4 address: This field displays the current configured IPv4 address. IPv4 is the traditional
4 octet Internet Protocol address. An IPv4 address comprises 4 8-bit numbers separated
by a period. Each number can be between 0 and 255 (some of the fields have more strict
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. B
Chapter 3 - Managed Switch Software Monitoring
limitations). The IPv4 address can be manually configured in the “System Settings” tab
under the Main Settings section or the address can be set to be automatically retrieved
using the DHCP protocol. If the address has been configured via DHCP, it will indicate
this. This field also indicates the Subnet Mask by using the ‘slash’ notation that indicates
the number of bits that are 1 in the mask. For example: A Subnet Mask of 255.255.0.0
would be indicated by a /16. A Subnet Mask of 255.255.255.0 would be indicated by a
/24 and so on. The subnet mask is accessible via SNMP as RFC1213-MIB::IPADENTNETMASK.<IPADDRESS> where <IPADDRESS> is the IP address of the switch (example:
192.168.0.1).
IPv6 address: This field displays the current configured IPv6 address. IPv6 is the newer
standard of Internet Protocol addressing that greatly expands the number of addressing
possibilities. Instead of the standard 4 x 8-bit address format that is used IPv4, IPv6 uses
8 fields of 16 bit values separated by colons. Each address display in hex format. If one
particular fields contains a 0, a :: can be used. An IPv6 address can also be retrieved by
DHCP. This field also uses the / designator for the subnet mask.
Default Gateway: This field contains the IP address of the router that this switch should
send external packets to. This address can be assigned manually in the “System Settings”
tab under the Main Settings section or can be retrieved automatically through DHCP. The
default gateway is accessible via SNMP as RFC1213-MIB::IPROUTENEXTHOP.
Serial Number: This is the serial number assigned to this switch at the factory and cannot be
changed.
Firmware revision: This is the current running firmware revision of this switch.
MAC address: This is the MAC address of this switch. It is configured at the factory and
cannot be changed.
Uptime: This is the amount of time this switch has been running since power was applied.
This data is available via SNMP as SYSTEM.SYSUPTIME.0.

Network Statistics
The Network Statistics display can be a very useful diagnostic tool for indication of the type
of traffic and packets that the switch is receiving.
Chapter 3 - Managed Switch Software Monitoring
RMON Statistics: RMON stands for “Remote Monitoring” statistics and includes the
following:
• Drop Events = The number of packets that have been dropped by the switch because of a lack of
resources and/or large queues.
• Octets = The number of data 8-bit units received into this port.
• Packets = The number of Ethernet packets received into this port.
• Broadcast packets = The number of broadcast packets received into this port.
• Multicast packets = The number of multicast packets received into this port.
• CRC Align errors = The number of Ethernet packets received into this port with an invalid CRC.
• Undersize packets = The number of Ethernet packets received into this port that were less than 64
bytes in size but contained a valid CRC (64 bytes is the minimum required in Ethernet).
• Oversize packets = The number of Ethernet packets received into this port that were greater than
1536 bytes in size but contained a valid CRC (1536 is the maximum size allowed in Ethernet).
• Fragments = The number of Ethernet packets received into this port that were less than 64 bytes in
size and did not contain a valid CRC.
• Jabbers = The number of Ethernet packets received into this port that were greater than 1536 bytes
in size and did not contain a valid CRC.
• Collisions = The number of collisions detected on this port.
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. B

Chapter 3 - Managed Switch Software Monitoring
• 64-octet Packets = The number of Ethernet packets received into this port that were 64 bytes in
length.
• 65 – 127-octet Packets = The number of Ethernet packets received into this port that were between
65 and 127 bytes in length.
• 128 – 255-octet Packets = The number of Ethernet packets received into this port that were
between 128 and 255 bytes in length.
• 256 – 511-octet Packets = The number of Ethernet packets received into this port that were
between 256 and 511 bytes in length.
• 512 – 1023-octet Packets = The number of Ethernet packets received into this port that were
between 512 and 1023 bytes in length.
• 1024 – 1518-octet Packets = The number of Ethernet packets received into this port that were
between 1024 and 1518 bytes in length.
3-6
Ether-like statistics: The Ether-like statistics provide information on possible hardware,
electrical and/or noise problems on the network.
• Alignment Errors = These errors are more indicative of receiving the improper number of bits.
These errors are a good indication of noise and/or electrical problems. Check the wiring and
routing of cables in the event that many of these errors are seen.
• FCS Errors = This is the error that results from an incorrect CRC calculation. These errors along
with the Alignment Errors indicate noise and/or electrical problems. Check the wiring and routing
of cables in the event that many of these errors are seen.
• Single Collision Frames = This error occurs when only 1 collision occurs and the sending device is
able to send the packet on the subsequent attempt.
• Multiple Collision Frames = This error occurs when collisions occur on more than 1 attempt to
send a packet from a device.
• SQE Test Errors = The Signal Quality Error test verifies that the collision detection circuit is
working correctly. If the device does not detect the SQE test, this causes an error.
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. B
Chapter 3 - Managed Switch Software Monitoring
• Deferred Transmissions = A deferred transmission occurs when the device detects a carrier signal (a
device is already transmitting).
• Late Collisions = In some situations, a collision is not detected until after the Ethernet device has
started transmitting the packet. This is called a Late Collision. A Late Collision is more specifically
defined as a collision that is detected 51.2 microseconds after the device has started sending on a
10BASE-T network and 5.12 microseconds on a 100BASE-T network. Late collisions are usually
caused by improper network configurations, compliance issues between devices, incorrect cabling
and/or fault Network Interface Cards.
• Excessive Collisions = As part of the CSMA/CD mechanism, an Ethernet device will attempt to
re-transmit a frame 16 times if a collision is detected. If the device is unsuccessful after 16 times, it
will give up and that frame will not be transmitted.
• Internal MAC Transmit Errors = This error occurs when frames fail to be transmitted correctly
due to an internal MAC sub-layer transmit error.
• Carrier Sense Errors = This error occurs when the carrier sense is lost during a transmission from
the Ethernet device. The error only increments once during the transmission even if the carrier
sense is lost and regained multiple times during that transmission.
• Frame Too Long = This error occurs when a frame is encountered that exceeds the maximum
frame size.
• Internal MAC Receive Errors = This error occurs when frames fail to be received correctly due to
an internal MAC sub-layer receive error.
• Symbol Errors = These errors occur when the device could not correctly decode a symbol that has
been received. This is usually indicative of bad cabling and/or electrical noise problems. A symbol
is a waveform change on the wire that may contain 1 or many bits of information.

Spanning Tree Status
This section shows the current status of the Spanning Tree redundancy feature of the switch.
For more information on the particular details of the Spanning Tree features of the switch,
refer to the “Spanning Tree Settings” section under the “Redundancy Settings” section of this
document.
3-8
On this page, the color highlighting the port number indicates the speed:
Yellow = 10 Mbps
Green = 100 Mbps
Red = 1000 Mbps
Redundancy protocol: This is the protocol that the switch has been configured for. The
selections available are Spanning Tree Protocol, Rapid Spanning Tree Protocol or None.
Designated root: This field specifies which device is the Root switch and what the Bridge ID
of that switch is along with the MAC ID.
Topology changes: This counter tracks the number of times that the topology has changed
on the network layout. There are a number of things that can cause the topology to change.
If the link is lost on a port that is forwarding and the switch has to change its path, this will
cause a topology change. If a Topology Change Notice is received by the switch from some
other switch, the counter will also increment.
Time since last chg: Informs how long it has been since the last topology change occurred.
Port: The number of the port. This corresponds to the labels on the switch.
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. B
Chapter 3 - Managed Switch Software Monitoring
Name: The user configured name of the port.
Status: The configured state of the port in the STP protocol (included or excluded). An
included port is part of the managed network. An excluded port will not be used as part
of the managed network. For example, a single uplink from a managed network of factory
devices to a business network would be configured to be excluded from STP use. A pair of
ports configured for Real-Time Ring should be excluded from Spanning Tree.
State: The STP/RSTP state of the port:
STP:
• Blocking = A port in this state does not participate in frame relay (pass frames received to other
locations). Once a port is in this state, it prevents frame duplication caused by multiple paths in an
active topology.
• Listening = A port in this state is about to participate in frame relay, but is not involved in any
relay of frames (no frames will be forwarded). The reason for not entering frame relay immediately
is to ensure that there are no temporary loops introduced when the network topology is changing.
During this state, the switch will disable all learning states on its ports to prevent the race
conditions when ports are changing roles and the forwarding process will discard all frames and not
submit any frames for transmission. Meanwhile BPDUs (Configuration Messages - Bridge Protocol
Data Units) can still be received and forwarded to keep the algorithm running.
• Learning = A port in this state is about to participate in frame relay, but it is not involved in any
relay of frames. Frame relays are not performed to prevent the creation of temporary loops during
the active topology of a changing bridged LAN. In addition, the forwarding process will discard all
frames and not submit any frames for transmission. The reason for enabling learning is to acquire
information prior to any frame relay activities. Information gathered will be used and placed in the
filtering database (MAC table) to reduce the number of frames being unnecessarily relayed.
• Forwarding = A port in the forwarding state is currently participating in frame relay. BPDUs
will include the forwarding port in the computation of the active topology. BPDUs received are
processed according to the Spanning Tree algorithm and transmitted based on the hello time or
BPDU information received.
RSTP:
• Discarding = In this state, station location information is not added to the Filtering Database
(MAC table) because any changes in port role will make the Filtering Database information
inaccurate.
• Learning = In this state, information is being added to the Filtering Database under the assumption
that the port role is not changing. Gathering information before frame relay (forwarding state) will
reduce the number of frames sent out when entering the forwarding state.
• Forwarding = Frames will be forwarded to and from the particular port that is in the forwarding
state. In addition, during the forwarding state, the learning process is still incorporating station
information into the Filtering database.
Cost: The cost of using this port to reach other parts of the managed network. The cost
is used in calculating the best path from the switch to the root bridge. The lower the cost,
the more likely that the path will be used. See the configuration section for Spanning Tree
settings for more detail.

Real-Time Ring Status
Each ring that is configured is assigned a number and can be given a name. For more
information on the Real-Time Ring feature, refer to the “Real-Time Ring Settings” section
under the “Redundancy Settings” section of this document.
3-10
On this page, green hightlight on the ring number indicates the ring is complete, red
indicates the ring is broken. On the Port, green indicates both ends of the link are connected
and communicating. Red indicates on side of the link is not connected or communicating.
For each ring configured a Primary port is assigned and a Backup port (if the Primary port
is disrupted). The Ring Status page shows the status of the Primary port, its Link status, the
status of the Backup port and its Link status.
The Status field indicates whether the Ring is complete or if there is a break in the Ring. If
the Ring is broken at the switch being monitored, it will indicate “Local”. If the Ring is
broken at another switch, it will indicate “Remote”.

• Group: Displays the Multicast IP address of a particular multicast group.
• Port: Displays the port that the particular multicast group is active on.
• Reporter: Displays the IP address of the last host to report membership in this group on this
port. Hosts send IGMP reports to a switch or router for the purpose of having the switch or router
include them into a particular multicast group.
• Age: The number of seconds since this group was last reported on this port.
• Expiration: The number of seconds until this group will be dropped unless a new report is
received.

To configure the switch for network access, select Quick Setup from the Main menu to reach
the System Settings menu. The settings in this menu control the switch’s general network
configuration.
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. A
Chapter 4 - Managed Switch Software Setup
DHCP Enabled/Disabled: The switch can automatically obtain an IP address from a server
using the Dynamic Host Configuration Protocol (DHCP). This can speed up initial set up,
as the network administrator does not have to find an open IP address.
NOTE: If DHCP has been enabled, it will be necessary to connect to the console port serially or via USB in order to
ascertain which IP address has been assigned so that you may be able to access the Switch using the web browser.
IP address and Subnet Mask: The IP address of the switch can be changed to a user-defined
address along with a customized subnet mask.
NOTE: For additional security, advanced users can set the IP address to 0.0.0.0 to disable the web browser access .
However, any features requiring an IP address (i.e., web interface, etc.) will no longer be available.
Default gateway: A Gateway address is the address of a router that connects two different
networks. This can be an IP address or a Fully Qualified Domain Name (FQDN) such as
“domainname.org”.
Primary DNS server: A DNS server address will be required if domain names are used in
the switch settings. A Domain Name System Server converts a name, such as “domainname.
org”, into an IP address that is usable in the Ethernet messaging. Consult your network
administrator for the proper DNS address for your network.
Secondary DNS server: A secondary DNS server can be configured in the case that the
Primary DNS server is unreachable.

Remote Access Security
This screen allows you to set your remote access security settings.
4-4
SNMP Access: Choose the level of SNMP access to allow.
• None: No SNMP access allowed.
• SNMPv1 & SNMPv2 access (no passwords): SNMP v1 and SNMPv2 access with community
string (None) sent in clear text and no password required.
• SNMPv3 access: SNMPv3 access with encrypted password.
• Basic and secure SNMP access: SNMPv1, SNMPv2 and SNMPv3 access allowed.
Terminal access: Choose the type of terminal access to allow
• None: No terminal access to the switch will be allowed.
• Non-secure access via telnet: Non-secure access via telnet protocol. Remote access is possible
through this protocol, although all information being transacted between server and client will be
sent as clear text. Should security be of concern, use the Secure Shell protocol instead.
• Secure access via SSH: Secure access can be achieved through the use of the Secure Shell protocol
(SSH), which implements strong authentication and secure communications using encryption.
Using this protocol will ensure that your login information never gets sent as clear text, keeping the
switch protected against possible attacks coming from the network.
Stride Industrial Ethernet Switches User Manual 2nd Ed. Rev. A
Chapter 4 - Managed Switch Software Setup
• SSH and telnet access: The switch can be accessed through secure (SSH) and non-secure (telnet)
terminal access.
The switch supports these encryption algorithms for SSH:
• 3DES
• Blowfish
• AES
• Arcfour
To take advantage of the SSH capability in the switch, you will need to use an SSH client
program. There are many SSH client programs available for you to log onto the host (the
switch).
Two open source SSH client programs are available on the Internet:
• Program name: OpenSSH for Windows: http://sshwindows.sourceforge.net/
• Program name: PuTTY: http://www.chiark.greenend.org.uk/~sgtatham/putty/
The SSH protocol requires some way for clients to be sure they are communicating with the
intended host. The host computes a “fingerprint” based on its key and provides that to the
client for verification. The first time a client program sees a fingerprint, it typically displays it
and asks something like “The host is offering me these credentials, should I trust it?”
If you agree, the fingerprint is stored for later reuse.
For the system to be secure, the fingerprint used for comparison must be transmitted “out of
band” (by a means other than the channel that is being secured by the fingerprint). In this
case, via documentation.
The RSA fingerprint for the managed switch’s encryption key is:
1e:0f:31:39:26:3f:23:8c:ba:7e:e9:d1:56:ff:98:f6
Web access: Choose the level of web access to allow.
• No web access: No web access allowed.
• HTTP access: Basic HTTP access allowed.
• Secure HTTP (HTTPS) access: Secure HTTP (HTTPS) required. Attempts to access the switch
via http will be redirected to the secure protocol.
• Basic and secure HTTP access: Basic and secure HTTP access allowed.
SNMP firmware loading: Allows or disallows loading firmware via the SNMP protocol.
Command line access: Allows or disallows Command Line (CLI) access.
Automatic Logout: Specify the number of minutes of inactivity before terminal sessions

Port Settings
The switch comes with default port settings that allow you to connect to the Ethernet
Ports without any configuration. Should there be a need to change the name of the ports,
negotiation settings or flow control settings, you can do this in the Port Settings menu.

Port Name: Each port in the managed switch can be identified with a custom name. Specify
a name for each port here.
Admin: Ports can be enabled or disabled in the managed switch. For ports that are disabled,
they are virtually non-existent (not visible in terms of switch operation or spanning tree
algorithm). Choose to enable or disable a port by selecting Enabled or Disabled, respectively.

Chapter 4 - Managed Switch Software Setup
Negotiation: All copper ports and gigabit fiber ports in the managed switch are capable
of auto-negotiation such that the fastest bandwidth is selected. Choose to enable autonegotiation or use fixed settings. 100Mbps fiber ports are fixed speed only.
Speed/Duplex/Flow Control: Each port can be set to allow speed and duplex to be
negotiated to any or all Speed/Duplex/Flow control options. Network performance can be
optimized by using Fixed Negotiation and restricting Speed/Duplex/Flow Control to a single
value if network traffic is known.
These options are available:
• 10h – 10 Mbps, Half Duplex
• 10f – 10 Mbps, Full Duplex
• 100h – 100 Mbps, Half Duplex
• 100f – 100 Mbps, Full Duplex
• 1000f – 1000 Mbps, Full Duplex
On managed switches with gigabit combination ports, those ports will have two rows,
a standard row of check boxes and a row labeled “SFP” with radio buttons. The SFP
setting independently sets the speed at which a transceiver will operate if one is plugged in.
Otherwise, the switch will use the fixed Ethernet port and the corresponding settings for it.
NOTE: The SFP settings are NOT automatically sensed or negioated. If a 100 Mbps SFP is installed in the switch, that
port must be manually set on the port settings page to 100 Mbps.
Flow Control: Flow control can also be enabled or disabled, and is indicated by ‘FC’ when
enabled. Devices use flow control to ensure that the receiving devices takes in all the data
without error. If the transmitting device sends at a faster rate than the receiving device,
then the receiving device will eventually have its buffer full. No further information can be
taken when the buffer is full, so a flow control signal is sent to the transmitting device to
temporarily stop the flow of incoming data.

Port Mirroring
In an unmanaged switch, each port is filtered to only send and receive Ethernet packets to
devices physically connected to that port. This makes it impossible to view the messages
occurring between two other devices from a third device (such as a PC running a tool like
“Wireshark”).
The mirroring option is ideal for performing diagnostics by allowing traffic that is being sent
to and received from one or more source ports to be replicated out the monitor port.
Choose a monitor port.
Choose the source ports to be mirrored (monitored). For each source port choose the data
to monitor: choose to monitor messages being sent (select Egress), messages being received
(select Ingress) or messages being sent and received (select Both).
NOTE: The Ingress Only option is not supported on SE-SW5M-xxx and SE-SW8M-xxx models.

To view the traffic, connect a PC running network monitoring software (such as Wireshark)
to the Monitor port.

Set IP per Port
The switch may provide an IP address to one device on each network port. This feature may
be turned on and off for the whole switch and individually controlled for each port.
This feature is not a DHCP service. With Set IP per Port enabled on a port, the switch will
respond to a DHCP request on that port with an IP address only.
For the feature to function properly, the host and network must meet the following criteria:
1. A single host must be directly connected to the switch port.
2. The host must not require a Subnet Mask to be offered.
3. The host and network must not require a Default Gateway to be offered.
4. There must be no other DHCP server on the network.
5. VLAN’s must not be configured on the network.
NOTE: Productivity3000, ECOM/ERM modules and C-more panels require a Subnet Mask in the DHCP.

Switch Time Settings
This screen allows you to configure the switch’s time settings, including time zone, current
date and time as well as an NTP (Network Time Protocol) time server.
4-10
NTP server: You may specify an NTP server to automatically set the switch’s clock. If a
DNS server is configured, you may use a fully qualified domain name; otherwise, you must
specify an IP address.
Timezone: This is the local timezone where the switch is installed. The switch will offset
accordingly from the current time configured in the switch.
Set Switch Date: This is where the date is set for the switch. The format of the date is YearMonth-Day (YYYY-MM-DD).
Set Switch Time: This is where the time is set for the switch. The format of the time is
hour:minute:second (HH:MM:SS).
There is also a “Get Browser Time” button to synchronize the switch’s clock to your local
browser’s time and a “Normalize Time” button to format the time in a manner that the
switch will view it. In other words, if the seconds are left out in time field, the normalize
button will show the seconds field that will be set when the Commit button is pressed.

Manage Firmware
The Manage firmware page displays the current status of each of the two firmware images on
a switch, and allows for changing which one will run the next time the switch is reset.
Default: Shows the current default firmware image to run when the switch is reset. May be
changed to run a different firmware on the next reset.
Running: Shows the current running firmware image. This may be different from the
current default firmware image if the switch failed to boot recently.
Version: Displays the firmware version number for each installed firmware. If the version
cannot be determined, this will report “Unknown”.
Health: Shows the health of each firmware image. The health can be one of the following:
• Healthy: The firmware is running or is expected to be in good enough shape to run.
• Broken: The firmware is known to be in a state that would prevent it from booting. The Default
column will not allow this image to be selected for booting.
• Unknown: The firmware may be bootable, but the switch cannot be certain. This will happen if
the switch is running the non-default firmware. This can happen if the default firmware somehow
became corrupt, or if the switch lost power part way through booting.
If the firmware that is currently running is not the default, and the switch is reset without
explicitly saving the default (“Commit Changes”), the current firmware will be run again. To

Install Firmware
The Install Firmware page allows the inactive firmware (the selection not marked Running on
the Manage Firmware page) to be replaced with a new version. To make the new version be
the running version on the switch, after uploading the new version, you must:
• Go to the Manage Firmware page
• Select the new version as default
• Reset the switch

Firmware may be directly uploaded to the switch from the local system.
MD5 Checksum (Optional): If an MD5 checksum of the file is available, it may be entered
into this field. Providing a checksum will ensure the firmware arrives at the switch intact and
without any glitches. An MD5 checksum is not required.
File name: Use the “Browse” button to locate the .fwb firmware file.
Firmware may also be uploaded to the switch from a remote machine serving the .fwb
firmware file. The server must be providing the file via TFTP, HTTP, HTTPS, FTP or
FTPS.
Protocol: Choose one of the following protocols to retrieve the .fwb firmware file: TFTP,

Redundancy Settings
Another benefit of using managed switches over unmanaged switches is their redundancy
capabilities. This allows you to have an Ethernet network with extra connections, so if one
path between two points on the network fails, another path can be used to deliver messages.
If one link or switch fails, another link or switch can take over transparently to prevent
unnecessary down time. So why not just physically connect each of the switches in your
network in various loop configurations such that there are always at least two paths going to
and from each switch? That would create a broadcast loop that will bring a network to its
knees very quickly.
In an unmanaged Ethernet network there can be only one path between any two ports on the
network. If there is more than one path from one switch to another a broadcast message (and
in some cases other messages) sent by the network will be forwarded until it completes a loop
by returning on the second path. Since the switches forward all broadcasts and do not keep
track of the messages they have sent, the returning message will be sent around the loop again
and again. A single message circulating forever around a loop at high speed is clearly not a
good thing, so no loops are allowed.
The limitations of having only one path are even simpler to see. If the one and only path
fails for any reason, such as a broken cable or power failure at one of the switches, there are
no paths left and no network traffic can get through. We need a way to add alternate paths
without creating loops. A redundancy protocol such as RSTP, a loop prevention protocol, is
used such that switches can communicate with each other to discover and prevent loops.
There are four methods of accomplishing redundancy in the Stride managed switches:
• Spanning Tree Protocol (STP)
• Rapid Spanning Tree Protocol (RSTP)
• Multiple Spanning Tree Protocol (MSTP)
• Real-Time Ring
The Spanning Tree Protocols (STP, RSTP and MSTP) are an industry standard and are thus
compatible with other manufacturer’s managed switches for situations where both need to
coexist and communicate. The recovery time, however, is slower with the Spanning Tree
Protocols than with the proprietary Real-Time Ring protocol. The merits of both will be
discussed in more detail below.

Spanning Tree Protocols:
In the diagram below all the links are the same speed, 100 Mbps. The root ports are those
connected directly to the root bridge because they have the lowest path cost (only one hop).
The paths that must go through another bridge (switch) have a higher path cost (two hops)
and are designated as backup ports (decisions made internal to the switch by the Spanning
Tree Protocol). The ports connected directly to end stations are assigned as edge ports
(manually assigned on the Spanning Tree Port Settings page) so that RSTP doesn’t waste
time considering them.

The Rapid Spanning Tree Protocol provides a standardized means for intelligent switches
(also called bridges) to enable or disable network paths so there are no loops, but there is an
alternative path if it is needed. Why is it called Rapid Spanning Tree Protocol?
• ‘Rapid’ – it is faster than the previous (and completely compatible) version called Spanning Tree
Protocol (STP).
• ‘Spanning’ – it spans (connects) all of the stations and switches of the network.
• ‘Tree’ – its branches provide only one connection between two points.
In a Spanning Tree network, only one bridge (managed switch) is responsible for forwarding
packets between two adjacent LAN segments to ensure that no loops exist in a LAN. To
ensure that only one bridge is responsible, all other bridges on the network must cooperate
with each other to form a logical spanning tree that defines the pathways that packets should
take from bridge to bridge.
The logical spanning tree has exactly one bridge that is assigned the role of root. All of the
other bridges need to have exactly one active path to the root. The job of the root bridge

is to notify all bridges connected in the tree that there has been a topology change and
restructuring of the tree is in progress (due to a communications link failure somewhere in
the network or a new switch added in the network). The root bridge is determined by the
bridge priority assigned to it and the MAC address.
By default, it is the bridge with the lowest MAC address that gets assigned the role as “root”,
but a specific bridge can be forced to be the root bridge by changing its bridge priority setting
(a lower number with respect to other bridges means higher priority, set on the Spanning
Tree Settings page).
Every communication path between each bridge (managed switch) on the network has an
associated cost. This “path cost” may be determined by the speed of each segment, because it
costs more time to move data at a slower speed, or the path cost can be manually configured
to encourage or discourage the use of a particular network. For example, you may not want
to use a particular high-speed link except when absolutely necessary because you pay a fee to a
service providor for data using that path, while another path is free (no monetary cost).
The path cost is the cumulative cost of all the hops from the root bridge to a particular port
on the network. A Spanning Tree network always uses the lower cost path available between
a port and the root bridge. When the available network connections change, it reconfigures
itself as necessary.
See the RSTP examples topic in this section for an example of how the path cost can be
utilized to establish the primary and backup connections.
During the start-up of a Spanning Tree Network, all bridges (managed switches) are
transmitting configuration messages (BPDUs) claiming to be the root. If a switch receives
a BPDU that is “better” than the one it is sending, it will immediately stop claiming itself
as the root and send the “better” root information instead. Assuming the working network
segments actually connect all of the switches, after a certain period of time there will be only
one switch that is sending its own root information and this switch is the root. All other
switches transmit the root bridge’s information at the rate of the root bridge’s “hello time” or
when the root bridge’s BPDU is received on one of their ports.
The factor for determining which switch is the root (has the “best” root information) is
the bridge priority and its tie-breaker, the switch MAC address. If a switch has more than
one path to get messages from the root, other information in the configuration message
determines which path is the best.
Once the root bridge is determined, all other switches see the root bridge’s information and
information about path (or paths) to the root. If more than one port provides a path to the
root the non-root switches must decide which port to use. They check all of their ports to
select the port that is receiving messages indicating the best path to the root.
The selected port for each bridge is called the root port. It provides the best path to
communicate with the root. The best path is determined first by the lowest total path
cost to the root (root path cost). Each port is assigned a cost (usually based on the speed)
for messages received on that port. The root path cost for a given path is just sum of the
individual port costs for that path. The lowest path cost indicates the shortest, fastest path to
the root. If more than one path has the same cost the port priority assigned to each port, and
its tie-breaker the port number pick the best path.
