Page 27
Transition Networks SISPM1040-182D
3.6 Cabling
Use four twisted-pair, Category 5e or above cabling for RJ-45 port connection. The
cable between the switch and the link partner (switch, hub, workstation, etc.) must
be less than 100 meters (328 ft.) long.
Fiber segment using single-mode connector type must use 9/125 μm single-mode
fiber cable. User can connect two devices in the distance up to 30km.
Fiber segment using multi-mode connector type must use 50 or 62.5/125 μm multi-
mode fiber cable. User can connect two devices up to 2km distances.
Gigabit Copper/SFP (mini-GBIC) combo port:
The Industrial switch has auto-detected Giga port—Gigabit Copper/SFP combo ports.
The Gigabit Copper (10/100/1000T) ports should use Category 5e or above UTP/STP
cable for the connection up to 1000Mbps. The small form-factor pluggable (SFP) is a
compact optical transceiver used in optical communications for both telecommunication
and data communications. The SFP slots supporting dual mode can switch the
connection speed between 100 and 1000Mbps. They are used for connecting to the
network segment with single or multi-mode fiber. Choose the appropriate SFP
transceiver to plug into the slots. Then use proper multi-mode or single-mode fiber
according to the transceiver. Fiber optic signals transmit at speeds up to 1000 Mbps and
are immune to electrical interference.
Note The SFP/Copper Combo port can’t both work at the same time. The SFP port
has higher priority than the copper port; if you insert the 1000M SFP
transceiver (connected to the remote device via fiber cable) into the SFP port,
the connection of the accompanying copper port link will down.
If you insert the 100M SFP transceiver into the SFP port even without a fiber
connection to the remote, the connection of the accompanying copper port will
link down immediately.

4.1 X-Ring Application
The industrial switch supports the X-Ring protocol that can help the network recover
from connection failure within 20ms or less, and make the network system more reliable.
The X-Ring algorithm is similar to spanning tree protocol (STP) algorithm but its recovery
time is faster than STP. The following figure is a sample X-Ring application.

4.2 Coupling Ring Application
A network may have more than one X-Ring group. The coupling ring function can
connect each X-Ring for redundant backup. It can ensure transmissions between two
ring groups do not fail. The following figure illustrates a coupling ring application.

4.3 Dual Homing Application
The Dual Homing function prevents lost connection between an X-Ring group and an
upper level/core switch. Assign two ports to be the Dual Homing ports in the X-Ring
group. The Dual Homing function only works when the X-Ring function is active. Each X-
Ring group only has one Dual Homing port.
[NOTE] In Dual Homing application architecture, the upper level switches need to
enable the Rapid Spanning Tree protocol.

6.5 IP Configuration
The switch is a network device which needs to be assigned an IP address for being
identified on the network. Users have to decide a means of assigning IP address to the
switch.
DHCP Client: Enable or disable the DHCP client function. When DHCP client
function is enabled, the switch will be assigned an IP address from the network
DHCP server. The default IP address will be replaced by the assigned IP address
on DHCP server. After the user clicks Apply, a popup dialog shows up to inform the
user that when the DHCP client is enabled, the current IP will lose and user should
find the new IP on the DHCP server.
IP Address: Assign the IP address that the network is using. If DHCP client function
is enabled, this switch is configured as a DHCP client. The network DHCP server
will assign the IP address to the switch and display it in this column. The default IP
is 192.168.1.77 or the user has to assign an IP address manually when DHCP
Client is disabled.
Subnet Mask: Assign the subnet mask to the IP address. If DHCP client function is
disabled, the user has to assign the subnet mask in this column field.
Gateway: Assign the network gateway for the switch. If DHCP client function is
disabled, the user has to assign the gateway in this column field. The default
gateway is 192.168.1.254.

6.6 DHCP Server
DHCP is the abbreviation of Dynamic Host Configuration Protocol that is a protocol for
assigning dynamic IP addresses to devices on a network. With dynamic addressing, a
device can have a different IP address every time it connects to the network. In some
systems, the device's IP address can even change while it is still connected. DHCP
also supports a mix of static and dynamic IP addresses. Dynamic addressing
simplifies network administration because the software keeps track of IP addresses
rather than requiring an administrator to manage the task. This means that a new
computer can be added to a network without the hassle of manually assigning it a
unique IP address.
The system provides the DHCP server function. Having enabled the DHCP server
function, the switch system will be configured as a DHCP server.

dynamic IP range. For example, dynamic IP is in the range between
192.168.1.100 ~ 192.168.1.200. In contrast, 192.168.1.100 is the Low IP address.
High IP Address: Type in an IP address. High IP address is the end of the
dynamic IP range. For example, dynamic IP is in the range between
192.168.1.100 ~ 192.168.1.200. In contrast, 192.168.1.200 is the High IP
address.
Subnet Mask: Type in the subnet mask of the IP configuration.
Gateway: Type in the IP address of the gateway in your network.
DNS: Type in the Domain Name Server IP Address in your network.
Lease Time (sec): It is the time period that system will reset the dynamic IP
assignment to ensure the dynamic IP will not remain occupied for a long time or
the server doesn’t know that the dynamic IP is idle.

6.10 SNTP Configuration
SNTP (Simple Network Time Protocol) is a simplified version of NTP which is an Internet
protocol used to synchronize the clocks of computers to some time reference. Because
time usually just advances, the time on different node stations will be different. With the
communicating programs running on those devices, it would cause time to jump forward
and back, a non-desirable effect. Therefore, the switch provides comprehensive
mechanisms to access national time and frequency dissemination services, organize the
time-synchronization subnet and the local clock in each participating subnet peer.
Daylight saving time (DST) is the convention of advancing clocks so that afternoons
have more daylight and mornings have less. Typically clocks are adjusted forward one
hour near the start of spring and are adjusted backward in autumn.
SNTP Client: Enable/disable SNTP function to get the time from the SNTP server.
Daylight Saving Time: This is used as a control switch to enable/disable daylight
saving period and daylight saving offset. Users can configure Daylight Saving
Period and Daylight Saving Offset in a certain period time and offset time while
there is no need to enable daylight saving function. Afterwards, users can just
enable this without assigning Daylight Saving Period and Daylight Saving Offset
again.
UTC Timezone: Universal Time, Coordinated. Set the switch location time zone.
The following table lists the different location time zone for your reference.

6.14 Port Control
In Port control you can configure the settings of each port to control the connection
parameters, and the status of each port is listed beneath.
Port: Use the scroll bar and click on the port number to choose the port to be
configured.
State: Current port state. The port can be set to disable or enable mode. If the port
state is set as ‘Disable’, it will not receive or transmit any packet.
Negotiation: Auto and Force. Being set as Auto, the speed and duplex mode are
negotiated automatically. When you set it as Force, you have to set the speed and
duplex mode manually.
Speed: It is available for selecting when the Negotiation column is set as Force.
When the Negotiation column is set as Auto, this column is read-only.
Duplex: It is available for selecting when the Negotiation column is set as Force.
When the Negotiation column is set as Auto, this column is read-only.
Flow Control: Whether or not the receiving node sends feedback to the sending
node is determined by this item. When enabled, once the device exceeds the input
data rate of another device, the receiving device will send a PAUSE frame which
halts the transmission of the sender for a specified period of time. When disabled,
the receiving device will drop the packet if too much to process.
Security: When the Security selection is set as ‘On’, any access from the device
which connects to this port will be blocked unless the MAC address of the device is
included in the static MAC address table. See the segment of MAC Address
Table—Static MAC Addresses.

6.15 Port Trunk
Port trunking is the combination of several ports or network cables to expand the
connection speed beyond the limits of any one single port or network cable. Link
Aggregation Control Protocol (LACP), which is a protocol running on layer 2, provides
a standardized means in accordance with IEEE 802.3ad to bundle several physical
ports together to form a single logical channel. All the ports within the logical channel
or so-called logical aggregator work at the same connection speed and LACP
operation requires full-duplex mode.
6.15.1 Aggregator setting
System Priority: A value which is used to identify the active LACP. The switch
with the lowest value has the highest priority and is selected as the active LACP
peer of the trunk group.
Group ID:
the trunk group.
LACP: When enabled, the trunk group is using LACP. A port which joins an
LACP trunk group has to make an agreement with its member ports first. Please
notice that a trunk group, including member ports split between two switches, has
to enable the LACP function of the two switches. When disabled, the trunk group
is a static trunk group. The advantage of having the LACP disabled is that a port
joins the trunk group without any handshaking with its member ports; but member
ports won’t know that they should be aggregated together to form a logic trunk
group.
Work ports: This column field allows the user to type in the total number of
active port up to four. With LACP static trunk group, e.g. you assign four ports

6.16 Port Mirroring
Port mirroring is a method for monitoring traffic in switched networks. Traffic through
ports can be monitored by one specific port, which means traffic that goes in or out
monitored (source) ports will be duplicated into mirror (destination) port.
Destination Port: There is only one port can be selected to be destination (mirror)
port for monitoring both RX and TX traffic which come from source port. Or, use one
of two ports for monitoring RX traffic only and the other one for TX traffic only. User
can connect mirror port to LAN analyzer or Netxray.
Source Port: The ports that user wants to monitor. All monitored port traffic will be
copied to mirror (destination) port. User can select multiple source ports by checking
the RX or TX check boxes to be monitored.

6.18 VLAN configuration
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain,
which allows you to isolate network traffic. Only the members of the same VLAN will
receive traffic from those of the same VLAN. Basically, creating a VLAN on a switch is
the logical equivalent of reconnecting a group of network devices to another Layer 2
switch. However, all the network devices are still plugged into the same switch
physically.
This switch supports Port-based and 802.1Q (tagged-based) VLAN. The default
configuration of VLAN operation mode is “Disable”.

6.18.1 Port-based VLAN
A port-based VLAN basically consists of its members—ports, which means the VLAN
is created by grouping the selected ports. This method provides convenience for
users to configure a simple VLAN easily without complicated steps. 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 is enabled, VLAN-
tagging is ignored. The port-based VLAN function allows the user to create separate
VLANs to limit unnecessary packet flooding; however, for the purpose of sharing
resource, a single port called a common port can belong to different VLANs; all the
member devices (ports) in different VLANs have permission to access the common
port while they still cannot communicate with each other in different VLANs.

6.18.2 802.1Q VLAN
Virtual Local Area Network (VLAN) can be implemented on the switch to logically
create different broadcast domains.
When the 802.1Q VLAN function is enabled, all ports on the switch belong to default
VLAN of VID 1, which means they logically are regarded as members of the same
broadcast domain. The valid VLAN ID is in the range of number between 1 and 4094.
The number of VLAN groups is up to 256, including the default VLAN that cannot be
deleted.
Each member port of 802.1Q is on either an Access Link (VLAN-tagged) or a Trunk
Link (no VLAN-tagged). All frames on an Access Link carry no VLAN identification.
Conversely, all frames on a Trunk Link are VLAN-tagged. Additionally, there is the
third mode—Hybrid. A Hybrid Link can carry both VLAN-tagged frames and untagged
frames. A single port is supposed to belong to one VLAN group, except it is on a
Trunk/Hybrid Link.
The technique of 802.1Q tagging inserts a 4-byte tag, including VLAN ID of the
destination port—PVID, in the frame. With the combination of Access/Trunk/Hybrid
Links, communication across switches can send the packet through tagged and
untagged ports.

Enable GVRP Protocol: GVRP (GARP VLAN Registration Protocol) is a protocol
that facilitates control of virtual local area networks (VLANs) within a larger network.
GVRP conforms to the IEEE 802.1Q specification, which defines a method of
tagging frames with VLAN configuration data. This allows network devices to
dynamically exchange VLAN configuration information with other devices. For
example, having enabled GVRP on two switches, they are able to automatically
exchange the information of their VLAN database. Therefore, the user doesn’t need
to manually configure whether the link is trunk or hybrid, the packets belonging to
the same VLAN can communicate across switches. Tick this checkbox to enable
GVRP protocol. This checkbox is available while the VLAN Operation Mode is in
802.1Q mode.
Management VLAN ID: Only the VLAN members whose Untagged VID (PVID)
equals the value in this column will have permission to access the switch. The
default value is ‘0’ that means this is not enabled (all members in different VLANs
can access this switch).
Select the port you want to configure.
Link Type: There are 3 types of link type.
¾ Access Link: A segment which provides the link path for one or more stations
to the VLAN-aware device. An Access Port (untagged port), connected to the
access link, has an untagged VID (also called PVID). After an untagged frame
gets into the access port, the switch will insert a four-byte tag in the frame. The
contents of the last 12-bit of the tag is untagged VID. When this frame is sent
out through any of the access port of the same PVID, the switch will remove the
tag from the frame to recover it to what it was. Those ports of the same
untagged VID are regarded as the same VLAN group members.
Note: Because the access port doesn’t have an understanding of tagged frame, the
column field of Tagged VID is not available.
¾ Trunk Link: A segment which provides the link path for one or more VLAN-
Technical Support: 1-800-260-1312 International: 00-1-952-941-7600
Page 91
Transition Networks SISPM1040-182D-LR
aware devices (switches). A Trunk Port, connected to the trunk link, has an
understanding of tagged frame, which is used for the communication among
VLANs across switches. Which frames of the specified VIDs will be forwarded
depends on the values filled in the Tagged VID column field. Please insert a
comma between two VIDs.
Note:
1. A trunk port doesn’t insert tag into an untagged frame, and therefore the untagged
VID column field is not available.
2. It’s not necessary to type ‘1’ in the tagged VID. The trunk port will forward the frames
of VLAN 1.
3. The trunk port has to be connected to a trunk/hybrid port of the other switch. Both the
tagged VID of the two ports have to be the same.
¾ Hybrid Link: A segment which consists of Access and Trunk links. The hybrid
port has both the features of access and trunk ports. A hybrid port has a PVID
belonging to a particular VLAN, and it also forwards the specified tagged-
frames for the purpose of VLAN communication across switches.
Note:
1. It’s not necessary to type ‘1’ in the tagged VID. The hybrid port will forward the
frames of VLAN 1.
2. The trunk port has to be connected to a trunk/hybrid port of the other switch. Both
the tagged VID of the two ports have to be the same.
Untagged VID: This column field is available when Link Type is set as Access Link
and Hybrid Link. Assign a number in the range between 1 an 4094.

and is selected as the root. If the value is changed, the user must reboot the
switch. The value must be a multiple of 4096 according to the protocol standard
rule.
¾ Max Age (6-40): The number of seconds a switch waits without receiving
Spanning-tree Protocol configuration messages before attempting a
reconfiguration. Enter a value between 6 through 40.
¾ Hello Time (1-10): The time that controls the switch to send out the BPDU
packet to check RSTP current status. Enter a value between 1 through 10.

Path Cost: The cost of the path to the other bridge from this transmitting bridge at
the specified port. Enter a number 1 through 200,000,000.
Priority: Decide which port should be blocked by setting its priority as the lowest.
Enter a number between 0 and 240. The value of priority must be the multiple of 16.
Admin P2P: The rapid state transitions possible within RSTP are dependent upon
whether the port concerned can only be connected to exactly another 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 means the port is
regarded as a point-to-point link. False means the port is regarded as a shared link.
Auto means the link type is determined by the auto-negotiation between the two
peers.
Admin Edge: The port directly connected to end stations won’t create bridging loop
in the network. To configure the port as an edge port, set the port to “True” status.
Admin Non Stp: The port includes the STP mathematic calculation. True is not
including STP mathematic calculation. False is including the STP mathematic
calculation.
