2.2 Wiring Power Inputs
DC Power Input
Follow below steps to wire the redundant DC power inputs.
1. Insert positive and negative wires into V+ and
V- contacts respectively of the terminal block
connector
2. Tighten the wire-clamp screws to prevent DC
wires from being loosened.
3. Power 1 and Power 2 support power
redundancy and polarity reverse protection
functions.
4. Positive and negative power system inputs are
both accepted, but Power 1 and Power 2 must apply the same mode.
Note 1: It is a good practice to turn off input and load power, and to unplug
power terminal block before making wire connections. Otherwise, your
screwdriver blade can inadvertently short your terminal connections to the
grounded enclosure.
Note 2: The range of the suitable DC electric wire is from 12 to 24 AWG.
Note 3: If the 2 power inputs are connected, the switch will be powered from the
highest connected voltage. The unit will alarm for loss of power, either POWER1
or POWER2.
Note 4: Use a UL Listed Power supply with output rating 12-48VDC, minimum
1 A.
7
2.3 Wiring Digital Output
The switch provides two digital outputs, also known as Relay Output. The relay
contacts are energized (open) for normal operation and will close for fault
conditions. The fault conditions include power failure, Ethernet port link break or
other pre-defined events which can be configured in management UI.
The default (without power) state of the Digital Output is normal CLOSE state.
The ON/OFF states are controlled by software configuration.
Wiring digital output is exactly the same as wiring power input introduced in
chapter 2.2.

the screw after earth ground wire is connected.
2.5 Wiring Fast Ethernet Ports
The Fast Ethernet ports support 10Base-T and 100Base-TX, full or half duplex
modes. All the Fast Ethernet ports will auto-detect the signal from connected
devices to negotiate the link speed and duplex mode. Auto MDI/MDIX allows
users to connect another switch, hub or workstation without changing straight
through or crossover cables.
Note that crossover cables simply cross-connect the transmit lines at each end to
the received lines at the opposite end.
Note that Ethernet cables use pins 1, 2, 3, and 6 of an 8-pin RJ-45 connector. The
signals of these pins are converted by the automatic MDI-X function, as shown in
the table below:
Connect one side of an Ethernet cable into any switch port and connect the other
side to your attached device. The LNK LED will light up when the cable is correctly
connected. Refer to the LED Indicators section for descriptions of each LED
indicator. Always make sure that the cables between the switches and attached
devices (e.g. switch, hub, or workstation) are less than 100 meters (328 feet).
The wiring cable types are as below.

10Base-T: 2-pair UTP/STP Cat. 3, 4, 5 cable, EIA/TIA-568 100-ohm (100m)
100 Base-TX: 2-pair UTP/STP Cat. 5 cable, EIA/TIA-568 100-ohm (100m)
1000 Base-TX: 4-pair UTP/STP Cat. 5 cable, EIA/TIA-568 100-ohm (100m)
2.6 Wiring Fiber Ports
Small Form-factor Pluggable (SFP)
The SFP ports fulfill the SFP standard. To ensure the system reliability, it is
recommended to use the approved Gigabit SFP Transceiver. The web user
interface will show Unknown vendor type when choosing the SFP which is not
approved.
The way to connect the SFP transceiver is to Plug in SFP fiber transceiver fist.
Cross-connect the transmit channel at each end to the
receive channel at the opposite end as illustrated in the figure
below.
Note: This is a Class 1 Laser/LED product. Don’t look into the Laser/LED Beam.
2.7 Wiring Gigabit Combo Ports
The switch includes RJ-45 Gigabit Combo ports. The speed of the Gigabit
Ethernet copper port supports 10Base-T, 100Base-TX and 1000Base-TX. The
speed of the SFP port supports 1000Full Duplex.
2.8 Wiring RS-232 Console Cable
The switch attaches one RS-232 DB-9 to RJ-45 cable in the box. Connect the RJ-45
connector to the COM port of your PC, open Terminal tool and set up serial
settings to 9600, N,8,1. (Baud Rate: 9600 / Parity: None / Data Bit: 8 / Stop Bit: 1)

3 Preparation for Management
The switches provides both in-band and out-band configuration methods. You
can configure the switch via RS232 console cable if you don’t attach your admin
PC to your network, or if you lose network connection to your switch. This is
so-called out-band management. It wouldn’t be affected by network
connectivity.
The in-band management means you can remotely manage the switch via the
network. You can choose Telnet or Web-based management. You just need to
know the device’s IP address and you can remotely connect to its embedded
HTTP web pages or Telnet console.
Should you forget the IP address, you can use WeDashboard to discover the
device, check its IP address or assign new IP address. The WeDashboard can
discover the device across the subnet.

4.3 Port Configuration
Port Configuration group enables you to enable/disable port state, or configure
port auto-negotiation, speed, and duplex, flow control, rate limit control and port
aggregation settings. It also allows you to view port status and aggregation
information.
Following commands are included in this section:
4.3.1 Port Control
4.3.2 Port Status
4.3.3 Rate Control
4.3.4 Storm Control
4.3.5 Port Trunking
4.3.6 Command Lines for Port Configuration
4.3.1 Port Control
Port Control commands allow you to enable/disable port state, or configure the
port auto-negotiation, speed, duplex and flow control.
Select the port you want to configure and make changes to the port.
In State column, you can enable or disable the state of this port. Once you
disable the port stop to link to the other end and stop to forward any traffic. The
default setting is Enable which means all the ports are workable when you
receive the device.
In Speed/Duplex column, you can configure port speed and duplex mode of this
port. Below are the selections you can choose:
Fast Ethernet Port: AutoNegotiation, 10M Full Duplex(10 Full), 10M Half
48
Duplex(10 Half), 100M Full Duplex(100 Full) and 100M Half Duplex(100 Half).
Gigabit Ethernet Port: AutoNegotiation, 10M Full Duplex(10 Full), 10M Half
Duplex(10 Half), 100M Full Duplex(100 Full), 100M Half Duplex(100 Half), 1000M
Full Duplex(1000 Full), 1000M Half Duplex(1000 Half).
The default mode is Auto Negotiation mode.
In Flow Control column, “Symmetric” means that you need to activate the flow
control function of the remote network device in order to let the flow control of
that corresponding port on the switch to work. “Disable” means that you don’t
need to activate the flow control function of the remote network device, as the
flow control of that corresponding port on the switch will work anyway.
Once you finish configuring the settings, click on Apply to save the configuration.
Technical Tips: If both ends are not at the same speed, they can’t link with each
other. If both ends are not in the same duplex mode, they will be connected by
half mode.
4.3.2 Port Status
Port Status shows you current port status.
The switch supports SFP fiber transceiver with Digital Diagnostic Monitoring
(DDM) function that provides real time information of SFP transceiver and allows
user to diagnostic the optical fiber signal received and launched.
The information of SFP DDM will listing on another table.
The description of the columns is as below:
Port: Port interface number.
Type: 100TX -> Fast Ethernet port. 1000TX -> Gigabit Ethernet port.
Link: Link status. Up -> Link UP. Down -> Link Down.
State: Enable -> State is enabled. Disable -> The port is disable/shutdown.
49
Speed/Duplex: Current working status of the port.
Flow Control: The state of the flow control.
SFP Vendor: Vendor name of the SFP transceiver you plugged.
Wavelength: The wave length of the SFP transceiver you plugged.
Distance: The distance of the SFP transceiver you plugged.
Reload: reload the all SFP port information.
Scan all: scan the SFP DDM transceiver and display the information.
Eject: Eject the SFP transceiver. You can eject one port or eject all by click the icon
“Eject All”.
Temperature: The temperature spcific and current detected of DDM SFP
transceiver.
Tx Power (dBm): The specification and current transmit power of DDM SFP
transceiver.
Rx Power (dBm): The specification and current received power of DDM SFP
transceiver.
Note: 1. Most of the SFP transceivers provide vendor information which
allows your switch to read it. The UI can display vendor name, wave
length and distance of all Westermo SFP transceiver family. If you see
Unknown info, it may mean that the vendor doesn’t provide their
information or that the information of their transceiver can’t be read.
2. if the plugged DDM SFP transceiver is not certified by Westermo, the
DDM function will not be supported. But the communication will not be
disabled.
4.3.3 Rate Control
Rate limiting is a form of flow control used to enforce a strict bandwidth limit at a
port. You can program separate transmit (Egress Rule) and receive (Ingress Rule)
rate limits at each port, and even apply the limit to certain packet types as
described below.
The figure below shows you the Limit Rate of Ingress and Egress. You can type
50
the volume in the blank. The volume of the switch is step by 8Kbps.
4.3.4 Storm Control
The Storm Control is similar to Rate Control. Rate Control filters all the traffic
over the threshold you configure in the User Interface. Storm Control allows user
to define the Rate for specific Packet Types.

Packet type: You can assign the Rate for specific packet types based on packet
number per second. The packet types of the Ingress Rule listed here include
Broadcast, DLF (Destination Lookup Failure) and Multicast. Choose
Enable/Disable to enable or disable the storm control for a specific port.
Rate: This column allows you to manually assign the limit rate of the port. The
unit is packets per second. The limit range is from 1 to 262143 packets/sec, zero
means no limit. The maximum available value of Fast Ethernet interface is
148810 and is the maximum packet number of the 100M throughput.
Enter the Rate field of the port you want assign, type the new value and click
Enter key first. After assigned or changed the value for all the ports you want
configure. Click on Apply to apply the configuration of all ports. The Apply
command applied all the ports’ storm control value.
4.3.5 Port Trunking
Port Trunking configuration allows you to group multiple Ethernet ports and to
increase link bandwidth. The aggregated ports can be viewed as one physical port
so that the bandwidth is higher than merely one single Ethernet port. The
member ports of the same trunk group can balance the loading and backup for
each other. Port Trunking feature is usually used when you need higher
bandwidth for backbone network. This is an inexpensive way for you to transfer
more data.
There are some different descriptions for the port trunking. Different
manufacturers may use different descriptions for their products, like Link
Aggregation Group (LAG), Link Aggregation Control Protocol, Ethernet Trunk,
Ether Channeletc. Most of the implementations now conform to IEEE standard,
802.3ad.
The aggregated ports can interconnect to the other switch which also supports
Port Trunking. The switch supports two types of port trunking. One is Static Trunk,
the other is 802.3ad. When the other end uses 802.3ad LACP, you should assign
802.3ad LACP to the trunk. When the other end uses non-802.3ad, you can then
use Static Trunk. In practical, the Static Trunk is suggested.
There are 2 configuration pages, Aggregation Setting and Aggregation Status.
52
Aggregation Setting
Trunk Size: The switch can support up to 8 trunk groups. Each trunk group can
support up to 8 member ports. Since the member ports should use same
speed/duplex, the maximum trunk size is decided by the port volume.
Group ID: Group ID is the ID for the port trunking group. Ports with same group
ID are in the same group. Click None, you can select the Trunk ID from Trunk 1 to
Trunk 8.
Trunk Type: Static and 802.3ad LACP. Each Trunk Group can only support Static or
802.3ad LACP. Choose the type you need here. The not active port can’t be setup
here.
Aggregation Status
This page shows the status of port aggregation. Once the aggregation ports are
negotiated well, you will see following status.

4.4 Network Redundancy
The switch firmware supports standard RSTP, MSTP, Multiple Super Ring, Rapid
Dual Homing.
Multiple Spanning Tree Protocol(MSTP) is a direct extension of RSTP. It can
provide an independent spanning tree for different VLANs. It simplifies network
management, provides for even faster convergence than RSTP by limiting the size
of each region, and prevents VLAN members from being segmented from the rest
of the group (as sometimes occurs with IEEE 802.1D STP).
Multiple Super Ring (MSR) technology supports 0 milliseconds for restoration and
less than 300 milliseconds for failover.
Advanced Rapid Dual Homing (RDH) technology also facilitates the switch to
connect with a core managed switch easily and conveniently. With RDH
technology, you can also group several Rapid Super Rings or RSTP cloud together,
which is also known as Auto Ring Coupling.
Besides ring technology, the switch also supports 802.1D-2004 version Rapid
Spanning Tree Protocol (RSTP). New version of RSTP standard includes
802.1D-1998 STP, 802.1w RSTP.
Following commands are included in this section:

4.4.1 STP Configuration
This page allows select the STP mode and configuring the global STP/RSTP Bridge
Configuration.
The STP mode includes the STP, RSTP, MSTP and Disable. Please select the STP
mode for your system first. The default mode is RSTP enabled. After select the STP
or RSTP mode, continue to configure the global Bridge parameters for STP and RSTP.
After select the MSTP mode, please go to MSTP Configuration page.
Figure below shows the web page which allows you to select the STP mode,
configure the global STP/RSTP/MSTP settings.
60
RSTP
RSTP is the abbreviation of Rapid Spanning Tree Protocol. If a switch has more than
one path to a destination, it will lead to message loops that can generate broadcast
storms and quickly bog down a network. The spanning tree was created to combat
the negative effects of message loops in switched networks. A spanning tree uses a
spanning tree algorithm (STA) to automatically sense whether a switch has more
than one way to communicate with a node. It will then select the best path
(primary), and block the other path(s). It will also keep track of the blocked path(s)
in case the primary path fails. Spanning Tree Protocol (STP) introduced a standard
method to accomplish this. It is specified in IEEE 802.1D-1998. Later, Rapid
Spanning Tree Protocol (RSTP) was adopted and represents the evolution of STP,
providing much faster spanning tree convergence after a topology change. This is
specified in IEEE 802.1w. In 2004, 802.1w is included into 802.1D-2004 version. This
switch supports both RSTP and STP (all switches that support RSTP are also
backward compatible with switches that support only STP).
Bridge Configuration
Priority (0-61440): RSTP uses bridge ID to determine the root bridge, the bridge
with the highest bridge ID becomes the root bridge. The bridge ID is composed of bridge priority and bridge MAC address. So that the bridge with the highest priority becomes the highest bridge ID. If all the bridge ID has the same priority, the bridge with the lowest MAC address will then become the root bridge.
Note: The bridge priority value must be in multiples of 4096. A device with a lower number has a higher bridge priority. Ex: 4096 is higher than 32768.
61
Note: The Web GUI allows user select the priority number directly. This is the convenience of the GUI design. When you configure the value through the CLI or SNMP, you may need to type the value directly. Please follow the n x 4096 rules for the Bridge Priority.
Max Age (6-40): Enter a value from 6 to 40 seconds here. This value represents the time that a bridge will wait without receiving Spanning Tree Protocol configuration messages before attempting to reconfigure.
If the managed Switch is not the root bridge, and if it has not received a hello message from the root bridge in an amount of time equal to Max Age, then the Managed Switch will reconfigure itself as a root bridge. Once two or more devices on the network are recognized as a root bridge, the devices will renegotiate to set up a new spanning tree topology.
The MAX Age value affects the maximum volume of the RSTP loop. In the RSTP BPDU packet, there is one field, message age which start from 0, add 1 after passed one hop in the RSTP loop. When the message age is larger than MAX Age, the BPDU would be ignored and the lower switches are separated to different
RSTP domain. The switches in other RSTP domain can’t be managed through upper
switch.
Since different RSTP aware switches may have their own mechanism to calculate the message age. So that this is most possibly occurred when interoperate
different vendors’ RSTP aware switches together. The maximum volume of the
RSTP domain is 23, configure the MAX Age lower than 23 is recommended.
Hello Time (1-10): Enter a value from 1 to 10 seconds here. This is a periodic timer that drives the switch to send out BPDU (Bridge Protocol Data Unit) packet to check current STP status.
The root bridge of the spanning tree topology periodically sends out a “hello”
message to other devices on the network to check if the topology is “healthy”. The “hello time” is the amount of time the root has waited during sending hello
messages.
Forward Delay Time (4-30): Enter a value between 4 and 30 seconds. This value is the time that a port waits before changing from Spanning Tree Protocol learning and listening states to forwarding state.
This is the amount of time of the Managed Switch will wait before checking to see if it should be changed to a different state.
Once you have completed your configuration, click on Apply to apply your settings.
Note: You must observe the following rule to configure Hello Time, Forwarding Delay, and Max Age parameter
× (Forward Delay Time – 1 sec) ≥ Max Age Time ≥ 2 × (Hello Time value + 1 sec)
4.4.2 STP Port Configuration
This page allows you to configure the port parameter after enabled STP or RSTP.
62
Port Configuration
Select the port you want to configure and you will be able to view current settings and status of the port.
Path Cost: Enter a number between 1 and 200,000,000. This value represents the
“cost” of the path to the other bridge from the transmitting bridge at the specified
port.
Priority: Enter a value between 0 and 240, using multiples of 16. This is the value that decides which port should be blocked by priority in a LAN.
Link Type: There are 3 link types for your selection-Auto, P2P and Share.
Some of the rapid state transitions that are possible within RSTP depend upon whether the port of concern can only be connected to another bridge (i.e. it is served by a point-to-point LAN segment), or if it can be connected to two or more bridges (i.e. it is served by a shared-medium LAN segment). This function allows link status of the link to be manipulated administratively. “Auto” means to auto
select P2P or Share mode. “P2P” means P2P is enabled; the 2 ends work in full duplex mode. While “Share” is enabled, it means P2P is disabled; the 2 ends may
connect through a share media and work in half duplex mode.
Edge Port: A port directly connected to the end stations cannot create a bridging loop in the network. To configure this port as an edge port, set the port to the Enable state. When the non-bridge device connects an admin edge port, this port will be in blocking state and turn to forwarding state in 4 seconds.
Once you finish your configuration, click on Apply to save your settings.
63
4.4.3 STP Information
This page allows you to see the information of the root switch and port status.
Root Information: You can see root Bridge ID, Root Priority, Root Port, Root Path
Cost and the Max Age, Hello Time and Forward Delay of BPDU sent from the root
switch.
Port Information: You can see port Role, Port State, Path Cost, Port Priority, Oper
P2P mode, Oper edge port mode and Aggregated (ID/Type).
4.4.4 MSTP (Multiple Spanning Tree Protocol) Configuration
MSTP is the abbreviation of Multiple Spanning Tree Protocol. This protocol is a
direct extension of RSTP. It can provide an independent spanning tree for
different VLANs. It simplifies network management, provides for even faster
convergence than RSTP by limiting the size of each region, and prevents VLAN
members from being segmented from the rest of the group (as sometimes occurs
64
with IEEE 802.1D STP).
While using MSTP, there are some new concepts of network architecture. A
switch may belong to different groups, act as root or designate switch, generate
BPDU for the network to maintain the forwarding table of the spanning tree.
With MSTP can also provide multiple forwarding paths and enable load balancing.
Understand the architecture allows you to maintain the correct spanning tree and
operate effectively.
One VLAN can be mapped to a Multiple Spanning Tree Instance (MSTI). For
example, the maximum Instance of the Managed Switch supports is usually 16,
range from 0-15. The MSTP builds a separate Multiple Spanning Tree (MST) for
each instance to maintain connectivity among each of the assigned VLAN groups.
An Internal Spanning Tree (IST) is used to connect all the MSTP switches within an
MST region. An MST Region may contain multiple MSTP Instances.
The figure shows there are 2 VLANs/MSTP Instances and each instance has its
Root and forwarding paths.
A Common Spanning Tree (CST) interconnects all adjuacent MST regions and acts
as a virtual bridge node for communications with STP or RSTP nodes in the global
network. MSTP connects all bridges and LAN segments with a single Common
and Internal Spanning Tree (CIST). The CIST is formed as a result of the running
spanning tree algorithm between switches that support the STP, RSTP, MSTP
protocols.
The figure shows the CST large network. In this network, a Region may has
different instances and its own forwarding path and table, however, it acts as a
single Bridge of CST.
65
To configure the MSTP setting, the STP Mode of the STP Configuration page should be changed to MSTP mode first.
After enabled MSTP mode, then you can go to the MSTP Configuration pages.
MSTP Region Configuration
This page allows configure the Region Name and its Revision, mapping the VLAN to Instance and check current MST Instance configuration. The network can be divided virtually to different Regions. The switches within the Region should have the same Region and Revision level.
Region Name: The name for the Region. Maximum length: 32 characters.
Revision: The revision for the Region. Range: 0-65535; Default: 0)
66
Once you finish your configuration, click on Apply to apply your settings.
New MST Instance
This page allows mapping the VLAN to Instance and assign priority to the instance. Before mapping VLAN to Instance, you should create VLAN and assign the member ports first. Please refer to the VLAN setting page.
Instance ID: Select the Instance ID, the available number is 1-15.
VLAN Group: Type the VLAN ID you want mapping to the instance.
Instance Priority: Assign the priority to the instance.
After finish your configuration, click on Add to apply your settings.
Current MST Instance Configuration
This page allows you to see the current MST Instance Configuration you added.
Click on “Apply” to apply the setting. You can “Remove” the instance or Reload“ the configuration display in this page.
67
4.4.5 MSTP Port Configuration
This page allows configure the Port settings. Choose the Instance ID you want to configure. The MSTP enabled and linked up ports within the instance will be listed in this table.
Note that the ports not belonged to the Instance, or the ports not MSTP activated will not display. The meaning of the Path Cost, Priority, Link Type and Edge Port is the same as the definition of RSTP.
Path Cost: Enter a number between 1 and 200,000,000. This value represents the
“cost” of the path to the other bridge from the transmitting bridge at the
specified port.
Priority: Enter a value between 0 and 240, using multiples of 16. This is the value that decides which port should be blocked by priority in a LAN.
Link Type: There are 3 types for you select. Auto, P2P and Share.
Some of the rapid state transitions that are possible within RSTP depend upon whether the port of concern can only be connected to another bridge (i.e. it is served by a point-to-point LAN segment), or if it can be connected to two or more bridges (i.e. it is served by a shared-medium LAN segment). This function allows link status of the link to be manipulated administratively. “Auto” means to
auto select P2P or Share mode. “P2P” means P2P is enabled, the 2 ends work in Full duplex mode. While “Share” is enabled, it means P2P is disabled, the 2 ends
may connect through a share media and work in Half duplex mode.
Edge: A port directly connected to the end stations cannot create a bridging loop in the network. To configure this port as an edge port, set the port to the Enable state. When the non-bridge device connects an admin edge port, this port will be
68
in blocking state and turn to forwarding state in 4 seconds.
Once you finish your configuration, click on Apply to save your settings.
4.4.6 MSTP Information
This page allows you to see the current MSTP information. Choose the Instance ID first. If the instance is not added, the information remains blank. The Root Information shows the setting of the Root switch. The Port Information shows the port setting and status of the ports within the instance.
Click on “Reload“ to reload the MSTP information display.
4.4.7 Multiple Super Ring (MSR)
The most common industrial network redundancy is to form a ring or loop.
Typically, the managed switches are connected in series and the last switch is
connected back to the first one.
The Multiple Super Ring has enhanced Ring Master selection and faster recovery
time. It is also enhanced for more complex ring application.
Advanced Rapid Dual Homing (RDH) technology also facilitates Managed Switch
69
to connect with a core managed switch easily and conveniently. With RDH
technology, you can also couple several Rapid Super Rings or RSTP cloud together,
which is also known as Auto Ring Coupling.
TrunkRing technology allows integrate MSR with LACP/Port Trunking. The
LACP/Trunk aggregated ports is a virtual interface and it can work as the Ring port
of the MSR.
MultiRing can be aggregated within one switch by using different Ring ID. The
maximum Ring number one switch can support is half of total port volume. The
feature saves much effort when constructing complex network architecture.
This page allows you to enable the settings for Multiple Super Ring and Rapid
Dual Homing.
New Ring: To create a Rapid Super Ring, just fill in the Ring ID which has range
from 0 to 31. If the name field is left blank, the name of this ring will be
automatically named with Ring ID.
Ring Configuration
ID: Once a Ring is created, this appears and cannot be changed.
Name: This field will show the name of the Ring. If it is not filled in when creating,
it will be automatically named by the rule “RingID”.
Version: The version of Ring can be changed here. There are three modes to
choose: Rapid Super Ring as default.
Device Priority: The switch with highest priority (highest value) will be
automatically selected as Ring Master. Then one of the ring ports in this switch
will become a forwarding port and the other one will become a blocking port. If
70
all of the switches have the same priority, the switch with the highest MAC
address will be selected as Ring Master.
Ring Port1: In Rapid Super Ring environment, you should have two Ring Ports. No
matter if the switch is Ring Master or not, when configuring RSR, two ports
should be selected as Ring Ports. For Ring Master, one of the ring ports will
become the forwarding port and the other one will become the blocking port.
Path Cost: Change the Path Cost of Ring Port1. If this switch is the Ring Master of
a Ring, then it determines the blocking port. The Port with higher Path Cost in the
two ring Port will become the blocking port, If the Path Cost is the same, the port
with larger port number will become the blocking port.
Ring Port2: Assign another port for ring connection
Path Cost: Change the Path Cost of Ring Port2
Rapid Dual Homing: Rapid Dual Homing is a feature of MSR. When you want to
connect multiple RSR or form a redundant topology with other vendors, RDH
could allow you to have maximum seven multiple links for redundancy without
any problem.
In Rapid Dual Homing, you don’t need to configure specific port to connect to
other protocol. The Rapid Dual Homing will smartly choose the fastest link for
primary link and block all the other links to avoid loop. If the primary link failed,
Rapid Dual Homing will automatically forward the secondary link for network
redundancy. If there are more connections, they will be standby links and recover
one of them if both primary and secondary links are down.
Ring status: To enable/disable the Ring. Please remember to enable the ring after
you add it.

4.5 VLAN
A Virtual LAN (VLAN) is a “logical” grouping of nodes for the purpose of limiting a
broadcast domain to specific members of a group without physically grouping the
members together. That means, VLAN allows you to isolate network traffic so
that only members of VLAN could receive traffic from the same VLAN members.
Basically, creating a VLAN from a switch is the logical equivalent of physically
reconnecting a group of network devices to another Layer 2 switch, without
actually disconnecting these devices from their original switches.
The switch supports 802.1Q VLAN. 802.1Q VLAN is also known as Tag-Based
VLAN. This Tag-Based VLAN allows VLAN to be created across different switches
(see Figure 1). IEEE 802.1Q tag-based VLAN makes use of VLAN control
information stored in a VLAN header attached to IEEE 802.3 packet frames. This
tag contains a VLAN Identifier (VID) that indicates which VLAN a frame belongs to.
Since each switch only has to check a frame’s tag, without the need to dissect the
contents of the frame, which also saves a lot of computing resources within the
switch.
QinQ
The QinQ is originally designed to expand the number of VLANs by adding a tag to the 802.1Q packets. The original VLAN is usually identified as Customer VLAN (C-VLAN) and the new added t–g - as Service VLAN(S-VLAN). By adding the additional tag, QinQ increases the possible number of VLANs. After QinQ enabled, the Managed Switch can reach up to 256x256 VLANs. With different standard tags, it also improves the network security.
VLAN Configuration group enables you to Add/Remove VLAN, configure port
Ingress/Egress parameters and view VLAN table.
Following commands are included in this section:
4.5.1 VLAN Port Configuration
4.5.2 VLAN Configuration
77
4.5.3 GVRP Configuration
4.5.4 VLAN Table
4.5.5 CLI Commands of the VLAN
4.5.1 VLAN Port Configuration
VLAN Port Configuration allows you to set up VLAN port parameters to specific
port. These parameters include PVID, Accept Frame Type and Ingress Filtering.
Figure 4.5.2 Web UI of VLAN configuration.
PVID: The abbreviation of the Port VLAN ID. Enter the port VLAN ID. PVID allows
the switches to identify which port belongs to which VLAN. To keep things simple,
it is recommended that PVID is equivalent to VLAN IDs.
The values of PVIDs are from 0 to 4095. But, 0 and 4095 are reserved. You can’t
input these two PVIDs. Value 1 is the default value and 2 to 4094 are valid and
available.
Tunnel Mode: This is the new command for QinQ. The command includes None,
802.1Q Tunnel and 802.1Q Tunnel Uplink. The figure shows the relationship
between 802.1Q Tunnel and 802.1Q Tunnel Uplink.
78
Following is the modes you can select.
None: Remian VLAN setting, no QinQ.
802.1Q Tunnel: The QinQ command applied to the ports which connect to the
C-VLAN. The port receives tagged frame from the C-VLAN. Add a new tag (Port
VID) as S-VLAN VID. When the packets are forwarded to C-VLAN, the S-VLAN
tag is removed.
After 802.1Q Tunnel mode is assigned to a port, the egress setting of the port
should be “Untag”, it indicates the egress packet is always untagged. This is
configured in Static VLAN Configuration table. Please refer to the VLAN
Configuration chapter in below.
802.1Q Tunnel Uplink: The QinQ command applied to the ports which connect
to the S-VLAN. The port receives tagged frame from the S-VLAN. When the
packets are forwarded to S-VLAN, the S-VLAN tag is kept.
After 802.1Q Tunnel Uplink mode is assigned to a port, the egress setting of the
port should be “Tag”, it indicates the egress packet is always tagged. This is
configured in Static VLAN Configuration table. Please refer to the VLAN
Configuration chapter in below.
For example, the VID of S-VLAN/Tunnel Uplink is 10, the VID of C-VLAN/Tunnel is
5. The 802.1Q Tunnel port receives tag 5 from C-VLAN, add tag 10 to the packet.
When the packets are forwarded to S-VLAN, tag 10 is kept.
EtherType: This column allows you to define the EtherType manually. This is
advanced QinQ parameter which allows to define the transmission packet type.
Accept Frame Type: This column defines the accepted frame type of the port.
There are 2 modes you can select, Admit All and Tag Only. Admit All mode means
that the port can accept both tagged and untagged packets. Tag Only mode
means that the port can only accept tagged packets.
Ingress Filtering: Ingress filtering helps VLAN engine to filter out undesired traffic
on a port. When Ingress Filtering is enabled, the port checks whether the
79
incoming frames belong to the VLAN they claimed or not. Then the port
determines if the frames can be processed or not. For example, if a tagged frame
from Engineer VLAN is received, and Ingress Filtering is enabled, the switch will
determine if the port is on the Engineer VLAN’s Egress list. If it is, the frame can
be processed. If it’s not, the frame would be dropped.
80
4.5.2 VLAN Configuration
In this page, you can assign Management VLAN, create the static VLAN, and
assign the Egress rule for the member ports of the VLAN.
Figure 4.5.2.1 Web UI of the VLAN Configuration.
Management VLAN ID: The switch supports management VLAN. The
management VLAN ID is the VLAN ID of the CPU interface so that only member
ports of the management VLAN can access the switch. The default management
VLAN ID is 1.
Static VLAN: You can assign a VLAN ID and VLAN Name for new VLAN here.
VLAN ID is used by the switch to identify different VLANs. Valid VLAN ID is
between 1 and 4094 and VLAN 1 is the default VLAN.
VLAN Name is a reference for network administrator to identify different VLANs.
The available character is 12 for you to input. If you don’t input VLAN name, the
system will automatically assign VLAN name for the VLAN. The rule is VLAN
(VLAN ID).
The steps to create a new VLAN: Type VLAN ID and NAME, and press Add to
create a new VLAN. Then you can see the new VLAN in the Static VLAN
Configuration table.
81
After created the VLAN, the status of the VLAN will remain in Unused until you
add ports to the VLAN.
Note: Before you change the management VLAN ID by Web and Telnet,
remember that the port attached by the administrator should be the member
port of the management VLAN; otherwise the administrator can’t access the
switch via the network.
Note: Currently the switch only support max 255 group VLAN.
Static VLAN Configuration
You can see the created VLANs and specify the egress (outgoing) port rule to be
Untagged or Tagged here.
Static VLAN Configuration table. You can see that new VLAN 3 is created. VLAN
name is test. Egress rules of the ports are not configured now.
-- : Not available
U: Untag: Indicates that egress/outgoing frames are not VLAN tagged.
T : Tag: Indicates that egress/outgoing frames are to be VLAN tagged.
Steps to configure Egress rules: Select the VLAN ID. Entry of the selected VLAN
turns to light blue. Assign Egress rule of the ports to U or T. Press Apply to apply
the setting. If you want to remove one VLAN, select the VLAN entry. Then press
Remove button.
82
4.5.3 GVRP configuration
GVRP allows users to set-up VLANs automatically rather than manual
configuration on every port of every switch in the network.
GVRP Protocol: Allow user to enable/disable GVRP globally.
State: After enable GVRP globally, here still can enable/disable GVRP by port.
Join Timer: Controls the interval of sending the GVRP Join BPDU and an instance
of this timer is required on a per-Port, per-GARP Participant basis
Leave Timer: Control the time to release the GVRP reservation after received the
GVRP Leave BPDU and an instance of the timer is required for each state machine
that is in the LV state
Leave All Timer: Controls the period to initiate the garbage collection of
registered VLAN. The timer is required on a per-Port, per-GARP Participant basis
83
4.5.4 VLAN Table
This table shows you current settings of your VLAN table, including VLAN ID,
Name, Status, and Egress rule of the ports.
VLAN ID: ID of the VLAN.
Name: Name of the VLAN.
Status: Static shows this is a manually configured static VLAN. Unused means this
VLAN is created by UI/CLI and has no member ports. This VLAN is not workable
yet. Dynamic means this VLAN is learnt by GVRP.
After created the VLAN, the status of this VLAN will remain in Unused status until
you add ports to the VLAN.

4.6 Private VLAN
The private VLAN helps to resolve the primary VLAN ID shortage, client ports’
isolation and network security issues. The Private VLAN provides primary and
secondary VLAN within a single switch.
Primary VLAN: The uplink port is usually the primary VLAN. A primary VLAN
contains promiscuous ports that can communicate with lower Secondary VLANs.
Secondary VLAN: The client ports are usually defined within secondary VLAN.
The secondary VLAN includes Isolated VLAN and Community VLAN. The client
ports can be isolated VLANs or can be grouped in the same Community VLAN.
The ports within the same community VLAN can communicate with each other.
However, the isolated VLAN ports can Not.
The figure shows the typical Private VLAN network. The SCADA/Public Server or
NMS workstation is usually located in primary VLAN. The clients PCs or Rings are
located within Secondary.
Private VLAN (PVLAN) Configuration group enables you to Configure PVLAN, PVLAN Port and see the PVLAN Information.
Following commands are included in this group:
4.6.1 PVLAN Configuration
4.6.2 PVLAN Port Configuration
4.6.3 CLI Commands of the PVLAN
4.6.1 PVLAN Configuration
PVLAN Configuration allows you to assign Private VLAN type. After created VLAN in VLAN Configuraiton page, the available VLAN ID will display here. Choose the Private VLAN types for each VLAN you want configure.
89
None: The VLAN is Not included in Private VLAN.
Primary: The VLAN is the Primary VLAN. The member ports can communicate
with secondary ports.
Isolated: The VLAN is the Isolated VLAN. The member ports of the VLAN are isolated.
Community: The VLAN is the Community VLAN. The member ports of the VLAN can communicate with each other.
4.6.2 PVLAN Port Configuration
PVLAN Port Configuration page allows configure Port Configuration and Private VLAN Association.
Private VLAN Association
Secondary VLAN: After the Isolated and Community VLAN Type is assigned in
Private VLAN Configuration page, the VLANs are belonged to the Secondary VLAN and displayed here.
Primary VLAN: After the Primary VLAN Type is assigned in Private VLAN Configuration page, the secondary VLAN can associate to the Primary VLAN ID. Select the Primary VLAN ID here.
Note: Before configuring PVLAN port type, the Private VLAN Association should be done first.
90
Port Configuraion
PVLAN Port T pe :
Normal: The Normal port is None PVLAN ports, it remains its original VLAN
setting.
Host: The Host type ports can be mapped to the Secondary VLAN.
Promiscuous: The promiscuous port can be associated to the Primary VLAN.
VLAN ID: After assigned the port type, the web UI display the available VLAN ID
the port can associate to.
For example:
1. VLAN Create: VLAN 2-5 are created in VLAN Configuration page.
2. Private VLAN Type: VLAN 2-5 has its Private VLAN Type configured in Private
VLAN Configuration page.
VLAN 2 is belonged to Primary VLAN.
VLAN 3-5 are belonged to secondary VLAN (Isolated or Community).
3. Private VLAN Association: Associate VLAN 3-5 to VLAN 2 in Private VLAN Association first.
4. Private VLAN Port Configuration
VLAN 2 – Primary -> The member port of VLAN 2 is promiscuous port.
VLAN 3 – Isolated -> The Host port can be mapped to VLAN 3.
VLAN 4 – Community -> The Host port can be mapped to VLAN 3.
VLAN 5 – Community -> The Host port can be mapped to VLAN
5. Result
VLAN 2 -> VLAN 3, 4, 5; member ports can communicate with ports in secondary VLAN.
VLAN 3 -> VLAN 2, member ports are isolated, but it can communicate with member port of VLAN 2..
VLAN 4 -> VLAN 2, member ports within the community can communicate with each other and communicate with member port of VLAN 2.
VLAN 5 -> VLAN 2, member ports within the community can communicate with each other and communicate with member port of VLAN 2.

4.7 Traffic Prioritization
Quality of Service (QoS) provides traffic prioritization mechanism and can also
help to alleviate congestion problems and ensure high-priority traffic is delivered
first. This section allows you to configure Traffic Prioritization settings for each
port with regard to setting priorities.
The switch QOS supports four physical queues, weighted fair queuing (WRR) and
Strict Priority scheme, which follows 802.1p COS tag and IPv4 TOS/DiffServ
information to prioritize the traffic of your industrial network.
Following commands are included in this section:
4.7.1 QoS Setting
4.7.2 QoS Priority Mode
4.7.3 CoS-Queue Mapping
4.7.4 DSCP-Queue Mapping
4.7.5 CLI Commands of the Traffic Prioritization
4.7.1 QoS Setting
In QoS setting, you should choose the QoS Priority Mode first, Port-Based, Cos or
DSCP modes. Choose the preferred mode and you can configure the next settings
in its own configuration pages. The other page of the mode you don’t select can’t
be configured.
96
Queue Scheduling
You can select the Queue Scheduling rule as follows:
Use a strict priority scheme. Packets with higher priority in the queue will always
be processed first, except that there is no packet with higher priority.
Use Weighted Round Robin scheme. This scheme allows users to assign new
weight ratio for each class. The 10 is the highest ratio. The ratio of each class is as
below:
Wx / W0 + W1 + W2 + W3 + W4 + W5 + W6 + W7 (Total volume of Queue 0-7)
4.7.2 Port-based Queue Mapping
Choose the Queue value of each port, the port then has its default priority. The
Queue 3 is the highest port-based queue, 0 is the lowest queue. The traffic
injected to the port follows the queue level to be forwarded, but the outgoing
traffic doesn’t bring the queue level to next switch.
After configuration, press Apply to enable the settings.
