3.4 Wiring the Power Inputs

Please follow the steps below to insert the power wire.

1. Insert AC or DC power wires into the contacts 1 and 2 for power 1, or 5 and 6 for power.

2. Tighten the wire-clamp screws for preventing the wires from loosing.

[NOTE]

The wire gauge for the terminal block should be in the range between 12 ~ 24 AWG.

3.5 Wiring the Fault Alarm Contact

The fault alarm contacts are in the middle of the terminal block connector as the picture shows below. Inserting the wires, the switch will detect the fault status of the power failure, or port link failure (available for managed model) and then forms an open circuit. The following illustration shows an application example for wiring the fault alarm contacts.

[NOTE]

The wire gauge for the terminal block should be in the range between 12 ~ 24 AWG.

Insert the wires into the fault alarm contacts

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 the 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. You can choose the appropriate SFP transceiver to plug into the slots. Then use proper multi-mode or single-mode fiber according to the transceiver. With fiber optic, it transmits at speed up to 1000 Mbps and you can prevent noise interference from the system.

Note

The SFP/Copper Combo port can’t both work at the same time. The SFP port has the higher priority than copper port; if you insert the 1000M SFP transceiver (which has connected to the remote device via fiber cable) into the SFP port, the connection of the accompanying copper port will link 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.

To connect the transceiver and LC cable, please follow the steps shown below:

First, insert the transceiver into the SFP module. Notice that the triangle mark is the bottom of the module.

To remove the LC connector from the transceiver, please follow the steps shown below:

First, press the upper side of the LC connector to release from the transceiver and pull it out.

Remove LC connector

Second, push down the metal loop and pull the transceiver out by the plastic handle.

Pull out from the transceiver

Chapter 4 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 is as below:

4.1 Pro-Ring2s Application

Pro-Ring II is a new Ring mechanism for Lantech Industrial Switches in which it eliminates the need to pre-set the Master switch in old Pro-Ring and yet to protect the network by much secure topologies than ever. Pro-Ring II works as a Ring Chain to reduce the risk of master switch linking down whereas the setup becomes much easier. Pro-Ring II can be backward compatible with old Pro-Ring by down-grading the Ring scheme to old one.

6.4.2 General – CPU Load Average

Sometimes the user was worry about that ‘ Could my switch process too many

network packets ? So the network throughput was keeping decreasing “. In this option, you can monitor the CPU of switch to see if the switch was in full loading status or not.

6.5 Time - SNTP

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.  UTC Timezone: Universal Time, Coordinated. Set the switch location time zone.

The following table lists the different location time zone for your reference.

6.7 IP Addressing – IPV4

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 192.168.16.1 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.

6.11 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.

6.6.1 DHCP Server - Server configuration

 DHCP Server: Enable or Disable the DHCP Server function. Enable—the switch

will be the DHCP server on your local network.

 Start IP Address: Type in an IP address. Low IP address is the beginning of the

dynamic IP range. For example, dynamic IP is in the range between 192.168.16.100 ~ 192.168.16.200. In contrast, 192.168.16.100 is the Low IP address.

 End 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 192.168.16.100 ~

192.168.16.200. In contrast, 192.168.16.200 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 (Hour): It is the time period that system will reset the dynamic IP

assignment to ensure the dynamic IP will not been occupied for a long time or the server doesn’t know that the dynamic IP is idle.

 And then, click

Apply

6.6.2 Client Table

When the DHCP server function is enabled, the system will collect the DHCP client information including the assigned IP address, the MAC address of the client device, the IP assigning type, status and lease time.

6.6.3 IP Bindings

Assign the dynamic IP address bound with the port to the connected client. The user is allowed to fill each port column with one particular IP address. When the device is connecting to the port and asks for IP assigning, the system will assign the IP address bound with the port.

6.12 Port - Configuration

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 No.: The port number which you want 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..

 Speed/Diplex: It can be set as auto or set speed and negotiated way manually.  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.

 Alies: Add description of each port to let the manager know the connected device of

each port, it will be showed by NMS utility.

6.17 Aggregation - Configuration

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.

6.17.1 Configuration



Group ID:

There are 5 trunk groups to be selected. Assign the "

Group ID

" to the

trunk group.

 TYPE: When choose LACP, 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 choose the total number of

active port up to four. With LACP static trunk group, e.g. you assign four ports to be the members of a trunk group whose work ports column field is set as two; the exceed ports are standby/redundant ports and can be aggregated if working ports fail. If it is a static trunk group (non-LACP), the number of work ports must equal the total number of group member ports.

6.18 Spanning Tree

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.

6.18.1 RSTP Setting

This web page provides the port configuration interface for RSTP. You can assign

higher or lower priority to each port. Rapid spanning tree will have the port with the higher priority in forwarding state and block other ports to make certain that there is no loop in the LAN.

 RSTP mode: The user must enable the RSTP function first before configuring

the related parameters.

 Priority : The switch with the lowest value has the highest priority 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.

 Max Age : 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.

 Hello Time : The time that controls the switch to send out the BPDU packet to

check RSTP current status. Enter a value between 1 through 10.

 Forward Delay Time : The number of seconds a port waits before changing

from its Rapid Spanning-Tree Protocol learning and listening states to the forwarding state. Enter a value between 4 through 30.

 Enable: Select the port which you want to be enabled with RSTP.  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.

 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.

 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.

6.20 Multicast Support

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, report packets, and manage IP multicast traffic through the switch. IGMP have three fundamental types of message shown as follows:

Message

Description

Query

A message sent from the querier (IGMP router or switch) asking for a response from each host belonging to the multicast group.

Report

A message sent by a host to the querier to indicate that the host wants to be or is a member of a given group indicated in the report message.

Leave Group

A message sent by a host to the querier to indicate that the host has quit being a member of a specific multicast group.

6.24 VLAN

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 same VLAN will receive traffic from the ones of the same VLAN. Basically, creating a VLAN on a switch is logically 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”.

6.24.1. VLAN Configuration

 Operation Mode: Enter the MAC address of the port that should permanently

forward traffic, regardless of the device network activity.

 802.1Q VLAN Setting:

Enable GVRP mode and define the Management VLAN ID.

GVRP (GARP VLAN Registration Protocol or Generic 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.

 Port Setting:

Select the port you want to configure.

 Link Type: There are 4 types of link type.

1. 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.

2. Trunk Link: A segment which provides the link path for one or more VLANaware 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:

A trunk port doesn’t insert tag into an untagged frame, and therefore the

untagged VID column field is not available.

It’s not necessary to type ‘1’ in the tagged VID. The trunk port will forward the

frames of VLAN 1.

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.

3. 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 taggedframes for the purpose of VLAN communication across switches.

4. QinQ (Double Tag VLAN) configuration: Double Tag VLAN is another mechanism employed in a Metro LAN in which it can save IP v4 address by residing groups of sub-VLANs (customer port) in a VLAN(Host) and utilizing the default gateway IP address of Double Tag VLAN sharing the same IP subnet mask. Double Tag VLAN in L2 provides enhances security between customer (each home), by dis-communication between the sub-VLANs, even they are located in the same LAN and have the same IP subnet mask. Better yet, the configuration is simple than assigning each VLAN as per port based VLAN to customer (each home).

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.

6.25 QoS

Quality of Service (QoS) is the ability to provide different priority to different applications, users or data flows, or to guarantee a certain level of performance to a data flow. QoS guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications such as voice over IP or Video Teleconferencing, since these often require fixed bit rate and are delay sensitive, and in networks where the capacity is a limited resource, for example in cellular data communication. In the absence of network congestion, QoS mechanisms are not required.

rate to process priority queue from High to lowest queue. For example, while the system processing, 1 frame of the lowest queue, 2 frames of the low queue, 4 frames of the middle queue, and 8 frames of the high queue will be processed at the same time in accordance with the 8,4,2,1 policy rule.

 Use a strict priority scheme: Always the higher queue will be processed first,

except the higher queue is empty.

 Priority Type: There are 5 priority type selections available—Port-based, TOS

only, COS only, TOS first, and COS first. Disable means no priority type is

selected.

6.25.2 Port Priority

Configure the priority level for each port. With the drop-down selection item of Priority Type above being selected as Port-based, this control item will then be available to set

the queuing policy for each port.

 Port x: Each port has 4 priority levels—High, Middle, Low, and Lowest—to be

chosen.

 Click

Apply

to have the configuration take effect.

6.25.3 COS Mapping to Queue

Set up the COS priority level. With the drop-down selection item of Priority Type above being selected as COS only/COS first, this control item will then be available to set the queuing policy for each port.

 COS priority: Set up the COS priority level 0~7—High, Middle, Low, Lowest.  Click

Apply

6.25.4 DSCP mapping to queue

Set up the DSCP priority. With the drop-down selection item of Priority Type above being selected as DSCP only/SDCP first, this control item will then be available to set the queuing policy for each port.

 DSCP priority: The system provides 0~63 DSCP priority level. Each level has 4 types of priority—High, Middle, Low, and Lowest. The default value is ‘Lowest’ priority for each level. When the IP packet is received, the system will check the DSCP level value in the IP packet that has received. For example, the user sets the DSCP level 25 as high, the system will check the DSCP value of the received IP packet. If the DSCP value of received IP packet is 25 (priority = high), and then the packet priority will have

highest priority.  Click

6.25. Port Mirroring

The Port mirroring is a method for monitor traffic in switched networks. Traffic through ports can be monitored by one specific port, which means traffic 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.

 And then, click

Apply

button.

6.26. Security

You can block the un-authorized client in this function.

6.26.1 IP Source Guard - Configuration

IP Source Guard function allows the user to assign 10 specific IP addresses that have permission to manage the switch through the http and telnet services for the securing switch management. The purpose of giving the limited IP addresses permission is to allow only the authorized personnel/device can do the management task on the switch.

 IP Security Mode: Having set this selection item in the Enable mode, the Enable

HTTP Server, Enable Telnet Server checkboxes and the ten security IP column

fields will then be available. If not, those items will appear in grey.

 Enable HTTP Server: Having ticked this checkbox, the devices whose IP

addresses match any one of the ten IP addresses in the Security IP1 ~ IP10 table will be given the permission to access this switch via HTTP service.

 Enable Telnet Server: Having ticked this checkbox, the devices whose IP

addresses match any one of the ten IP addresses in the Security IP1 ~ IP10 table will be given the permission to access this switch via telnet service.

 Enable SNMP Management: Having ticked this checkbox, the devices whose IP

addresses match any one of the ten IP addresses in the Security IP1 ~ IP10 table will be given the permission to access this switch via SNMP service.

6.26.2 IP Source Guard – Static Table

 Security IP 1 ~ 10: The system allows the user to assign up to 10 specific IP

addresses for access security. Only these 10 IP addresses can access and manage the switch through the HTTP/Telnet service once IP Security Mode is enabled.

 And then, click

Apply

to have the configuration take effect.

[NOTE]

Remember to execute the “Save Configuration” action, otherwise the new configuration will lose when the switch powers off.

6.26.3 802.1X/Radius

802.1x is an IEEE authentication specification which prevents the client from accessing a wireless access point or wired switch until it provides authority, like the user name and password that are verified by an authentication server (such as RADIUS server). After enabling the IEEE 802.1X function, you can configure the parameters of this function.

6.26.3.1 Configuration

 IEEE 802.1x Protocol: Enable or disable 802.1x protocol.  Radius Server IP: Assign the RADIUS Server IP address.  Server Port: Set the UDP destination port for authentication requests to the

specified RADIUS Server.

 Accounting Port: Set the UDP destination port for accounting requests to the

specified RADIUS Server.

 Shared Key: Set an encryption key for using during authentication sessions with

the specified RADIUS server. This key must match the encryption key used on the RADIUS Server.

 NAS, Identifier: Set the identifier for the RADIUS client.  Quiet Period: Set the period which the port doesn’t try to acquire a supplicant.  TX Period: Set the period the port waits for retransmit next EAPOL PDU during an

authentication session.

 Supplicant Timeout: Set the period of time the switch waits for a supplicant

response to an EAP request.

 Server Timeout: Set the period of time the switch waits for a server response to an

authentication request.

 Max Requests: Set the number of authentication that must time-out before

authentication fails and the authentication session ends.

 Reauth period: Set the period of time which clients connected must be re-

authenticated.
