Network Application
This chapter provides some sample applications to help user to have more
actual idea of industrial switch function application. A sample application of the
industrial switch as below:
Redundant Ring Application
The industrial switch supports the redundant ring protocol that can help your
network system to recovery from network connection failure within 300ms or
less, and make your network system more reliable. The redundant ring
algorithm is like as spanning tree protocol (STP) algorithm but it has faster
recovery time than STP. A sample redundant ring application figure as below:
16
Coupling Ring Application
In the network, it may have more than one redundant ring group. By using the
coupling ring function can connect each redundant ring for the redundant
backup. It can ensure the transmissions between two ring groups will no failure.
A sample of coupling ring application figure as below:
17
Dual Homing Application
Dual Homing function is to prevent the connection lose between redundant ring
group and upper level/core switch. The Dual Homing function only work when
the redundant ring function is active. The maximum Dual Homing port is one in
a redundant ring group.
[NOTE] In Dual Homing application architecture, the upper level switches need
to enable the Rapid Spanning Tree protocol.
18
Web-Based Management
This section introduces the configuration and functions of the Web-Based
management.
About Web-Based Management
On CPU board of the switch there is an embedded HTML web site residing in
flash memory, which offers advanced management features and allow users to
manage the switch from anywhere on the network through a standard browser
such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 5.0. And, it is applied
for Java Applets for reducing network bandwidth consumption, enhance access
speed and present an easy viewing screen.
[NOTE] By default, IE5.0 or later version does not allow Java Applets to open
sockets. The user has to explicitly modify the browser setting to enable Java
Applets to use network ports.
Preparing for Web Management

Prot Mirroring interface
VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which would, allow you to isolate network traffic so only the members
of the VLAN will receive traffic from the same members of VLAN. Basically,
creating a VLAN from a switch is logically equivalent of reconnecting a group of
25
network devices to another Layer 2 switch. However, all the network devices
are still plugged into the same switch physically.
The industrial switch supports port-based and 802.1Q (tagged-based) VLAN. In
the default configuration, VLAN operation mode default is “disable”.
VLAN Configuration interface
Port-based VLAN
Packets can go among only members of the same VLAN group. Note all
unselected ports are treated as belonging to another single VLAN. If the
port-based VLAN enabled, the VLAN-tagging is ignored.
In order for an end station to send packets to different VLANs, it itself has to be
either capable of tagging packets it sends with VLAN tags or attached to a
VLAN-aware bridge that is capable of classifying and tagging the packet with
different VLAN ID based on not only default PVID but also other information
about the packet, such as the protocol.

802.1Q VLAN
Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is
possible to create a VLAN across devices from different switch venders. IEEE
802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag
28
contains a VLAN Identifier (VID) that indicates the VLAN numbers.
All ports on the switch belong to default VLAN, VID is 1. The default VLAN can’t
be deleting. The maximum VLAN group is up to 64 VLAN groups.

browse the switch, only when the port of VLAN group ID is equal to the
Management VLAN ID. Fill the specific VLAN ID number in Management
VLAN ID column and mark the check box, and then click
Apply
button
to enable the function. For example: the management VLAN ID is 101, the
VLAN group ID 101 includes the port 1, 2, and 4. Therefore, only port 1, 2,
and 4 can remote management the switch. And, if the port is in two
29
different VLAN groups and one of VLAN group ID is equal to the assigned
Management VLAN ID, it still has the right to remote management the
switch.

RSTP Configuration
The Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree
Protocol and provides for faster spanning tree convergence after a topology
change. The system also supports STP and the system will auto detect the
connected device that is running STP or RSTP protocol.
System Configuration


Priority (0-61440): a value used to identify the root bridge. The bridge
with the lowest value has the highest priority and is selected as the
root. If the values change, user has to reboot the switch. The value
must be multiple of 4096 according to the protocol standard rule.

Max Age (6-40): the number of seconds a bridge waits without
receiving Spanning-tree Protocol configuration messages before
attempting a reconfiguration. Enter a value between 6 through 40.

Hello Time (1-10): the time that controls switch sends out the BPDU
packet to check RSTP current status. Enter a value between 1 through
10.

Forward Delay Time (4-30): the number of seconds which a port
waits before changing from its Rapid Spanning-Tree Protocol learning
and listening states to the forwarding state. Enter a value between 4

bridge at the specified port. Enter a number 1 through 200000000.
3. Priority: Decide which port should be blocked by priority in LAN. Enter a
number 0 through 240. The value of priority must be the multiple of 16.
4. Admin P2P: Some of the rapid state transactions that are possible within
RSTP are dependent upon whether the port concerned can only be
connected to exactly one other bridge (i.e. it is served by a point-to-point
LAN segment), or can be connected to two or more bridges (i.e. it is served
by a shared medium LAN segment). This function allows the P2P status of
the link to be manipulated administratively. True is P2P enabling. False is
42
P2P disabling.
5. Admin Edge: The port directly connected to end stations cannot create
bridging loop in the network. To configure the port as an edge port, set the
port to “True” status.
6. Admin Non Stp: The port includes the STP mathematic calculation. True is
not including STP mathematic calculation. False is including the STP
mathematic calculation.

Redundant Ring
Redundant Ring provides a faster redundant recovery than Spanning Tree
topology. The action is similar with STP or RSTP, but the algorithms not the
same.
In the redundant ring topology, every switch should enable redundant ring
function and assign two member ports in the ring. Only one switch in the
redundant ring group would be set as a backup switch that one of two member
ports would be blocking, called backup port, and another port is called working
port. Other switches are called working switches and their two member ports
are called working ports. When the network connection failure, the backup port
will automatically become a working port to recovery the failure.
The switch supports one Dip switch for configuring the switch as the ring master
or slave mode. The ring master has the rights to negotiate and place command
to other switches in the redundant ring group.
If there are 2 or more switches
are in master mode, then software will select the switch with lowest MAC
address number as the ring master. The redundant ring master ring mode will
be enabling by the DIP Switch. When the switch is set to the master ring mode,
the redundant ring configuration interface will display the switch as the master
ring message. Also, you can identify the switch as the ring master from the R.M.
LED panel of the LED panel on the switch.
The system also supports the coupling ring that can connect 2 or more
redundant ring group for the redundant backup function and dual homing
function that prevent connection lose between redundant ring group and upper
44
level/core switch.

Enable Redundant ring: To enable the redundant ring function. Marking
the check box to enable the redundant ring function.

1st & 2nd Working Ports: Assign two ports as the member ports. One port
will be working port and one port will be the backup port. The system will
automatically decide which port is working port and which port is backup
port.

Enable Coupling Ring: To enable the coupling ring function. Marking the
check box to enable the coupling ring function.

Coupling port: assign the member port

Control port: set the switch as the master switch in the coupling ring.

Enable Dual Homing: set up one of port on the switch to be the Dual
Homing port. In a redundant ring group, maximum Dual Homing port is one
in each redundant ring group. Dual Homing only work when the redundant
ring function enable.

Click

Redundant ring Interface
[NOTE]
1. When the redundant ring function enable, the RSTP has to be disabled. The
redundant ring function and RSTP function cannot be active at the same

time.
2. Remember to execute the “Save Configuration” action, otherwise the new
configuration will lose when the switch power off.
QoS Configuration
Configure Qos setting of the every port.

Oos Policy: Select the Qos policy rule

Using the 8,4,2,1 weight fair queue scheme: the switch will follow
8:4:2:1 rate to process priority queue from Hi to lowest queue. For
example: the system will process 8 high queue packets, 4 middle
queue packets, 2 low queue packets, and the one lowest queue
packets at the same time.

Use the strict priority scheme: the higher queue will always be
process first, except higher queue is empty.

Priority Type: each port has 5 priority type selections

Port-base: the port priority will follow the default port priority that
user has assigned – High, middle, low, or lowest

COS only: the port priority will only follow the COS priority that user
has assigned

TOS only: the port priority will only follow the TOS priority that user
has assigned

COS first: the port priority will follow the COS priority first, and then
other priority rule

TOS first: the port priority will follow the TOS priority first, and the
other priority rule

COS priority: Set the COS priority level 0~7
 TOS priority: the system provides 0~63 TOS priority level. Each level has
4 types of priority – high, mid, low, and lowest. The default value is “Lowest”
priority for each level. When the IP packet is received, the system will check
the TOS level value in the IP packet has received. For example: user set
the TOS level 25 is high. The port 1 is following the TOS priority policy only.
46
When the packet received by port 1, the system will check the TOS value of
the received IP packet. If the TOS value of received IP packet is 25(priority
= high), and then the packet priority will have highest priority.
[NOTE] QoS and Rate control cannot be existed at the same time.

IGMP
The Internet Group Management Protocol (IGMP) is an internal protocol of the
Internet Protocol (IP) suite. IP manages multicast traffic by using switches,
routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect
IGMP queries and report packets and manage IP multicast traffic through the
switch. IGMP have three fundamental types of message as follows:
Message
Description
A message sent from the querier (IGMP router or
Query
switch) asking for a response from each host
belonging to the multicast group.
A message sent by a host to the querier to indicate
Report
that the host wants to be or is a member of a given
group indicated in the report message.
A message sent by a host to the querier to indicate
Leave Group
that the host has quit to be a member of a specific
multicast group.
User can enable IGMP protocol and IGMP Query function in here. The IGMP
snooping information which VLAN ID, member port, and IP multicast addresses
range from 224.0.0.0 through 239.255.255.255 will be displayed as below:

Troubleshooting

Verify that is using the right power cord/adapter (DC 12-48V), please don’t
use the power adapter with DC output bigger than 48V, or it will burn this
switch down.

Select the proper UTP cable to construct your network. Please check that
you are using the right cable. use unshielded twisted-pair (UTP) or shield
twisted-pair ( STP ) cable for RJ-45 connections: 100Ω Category 3, 4 or 5
cable for 10Mbps connections or 100Ω Category 5 cable for 100Mbps
connections. Also be sure that the length of any twisted-pair connection
does not exceed 100 meters (328 feet).

Diagnosing LED Indicators: the Switch can be easily monitored through
panel indicators to assist in identifying problems, which describes common
problems user might encounter and where user can find possible solutions.

If the power indicator does turn on when the power cord is plugged in, it
might have a problem with power cord. Than check for loose power
connections, power losses or surges at power outlet. IF you still cannot
resolve the problem, contact the local dealer for assistance.

If the Industrial switch LED indicators are normal and the connected cables
are correct but the packets still cannot transmit. Please check the system’s
Ethernet devices’ configuration or status.
