Being set as Auto, the speed and duplex mode are negotiated automatically.
Chapter 5: Web-Based Management 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.
Chapter 5: Web-Based Management Aggregator setting This section provides Port Trunk-Aggregator Setting of each port from the Switch, the screen in Figure 5-20 appears. Figure 5-20: Port Trunk-Aggregator Setting interface (two ports are added to the left field with LACP enabled) This page includes the following fields: Object Description System Priority: A value which is used to identify the active LACP.
Chapter 5: Web-Based Management Object Description 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 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.
Chapter 5: Web-Based Management Figure 5-22: Static Trunking Group information This page includes the following fields: Object Description Group Key: This is a read-only column field that displays the trunk group ID. Port Member: This is a read-only column field that displays the members of this static trunk group. • LACP enabled Having set up the aggregator setting with LACP enabled, you will see the trunking group information between two switches on the tab of Aggregator Information.

Chapter 5: Web-Based Management Figure 5-25: Switch 1 Aggregator Information State Activity Having set up the LACP aggregator on the tab of Aggregator Setting, you can configure the state activity for the members of the LACP trunk group. You can tick or cancel the checkbox beside the state label. When you remove the tick mark of the port and click APPLY, the port state activity will change to Passive.
Chapter 5: Web-Based Management Figure 5-27: State Activity of Switch 2 NOTE: A link having two passive LACP nodes will not perform dynamic LACP trunk because both ports are waiting for an LACP protocol packet from the opposite device. 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.
Chapter 5: Web-Based Management This page includes the following fields: Object Description 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.
Chapter 5: Web-Based Management Figure 5-29: Rate Limiting interface • All the ports support port ingress and egress rate control. For example, assume port 1 is 10Mbps, users can set it's effective egress rate is 1Mbps, ingress rate is 500Kbps. The switch performs the ingress rate by packet counter to meet the specified rate o Ingress: Enter the port effective ingress rate (The default value is "0"). o Egress: Enter the port effective egress rate (The default value is "0").
Chapter 5: Web-Based Management VLAN Configuration VLAN Overview A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plug into the same switch physically.
Chapter 5: Web-Based Management Tagging - The act of putting 802.1Q VLAN information into the header of a packet. Untagging - The act of stripping 802.1Q VLAN information out of the packet header. • 802.1Q VLAN Tags The figure below shows the 802.1Q VLAN tag. There are four additional octets inserted after the source MAC address. Their presence is indicated by a value of 0x8100 in the Ether Type field. When a packet's Ether Type field is equal to 0x8100, the packet carries the IEEE 802.1Q/802.1p tag.
Chapter 5: Web-Based Management • Port VLAN ID Packets that are tagged (are carrying the 802.1Q VID information) can be transmitted from one 802.1Q compliant network device to another with the VLAN information intact. This allows 802.1Q VLAN to span network devices (and indeed, the entire network - if all network devices are 802.1Q compliant). Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the switch.
Chapter 5: Web-Based Management VLAN Configuration A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plug into the same switch physically.
Chapter 5: Web-Based Management Figure 5-31: VLAN - Port Based interface • Pull down the selection item and focus on Port Based then press to set the VLAN Operation Mode in Port Based mode. Click ADD to add a new VLAN group (The maximum VLAN groups are up to 64). Figure 5-32: VLAN - Port Based Add interface • Enter the group name and VLAN ID. Add the selected port number into the right field to group these members to be a VLAN group, or remove any of them listed in the right field from the VLAN.

When the 802.
Chapter 5: Web-Based Management • 802.1Q VLAN Port Configuration This page is used for configuring the Industrial Switch port VLAN. The VLAN per Port Configuration page contains fields for managing ports that are part of a VLAN. The port default VLAN ID (PVID) is configured on the VLAN Port Configuration page. All untagged packets arriving to the device are tagged by the ports PVID. Understanding the nomenclature of the Switch • IEEE 802.1Q Tagged and Untagged Every port on an 802.
Chapter 5: Web-Based Management • Hybrid: The port belongs to VLANs, and each VLAN is user-defined as tagged or untagged (full 802.1Q mode). Ports will strip the 802.1Q tag from all packets that out of those ports.
Chapter 5: Web-Based Management This page includes the following fields: Object Description 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.
Chapter 5: Web-Based Management Object Description Tagged VID: This column field is available when Link Type is set as Trunk Link and Hybrid Link. Assign a number in the range between 1 an 4094. NOTE: Access Link: Because the access port doesn't have an understanding of tagged frame, the column field of Tagged VID is not available. NOTE: Trunk Link 1. A trunk port doesn't insert tag into an untagged frame, and therefore the untagged VID column field is not available. 2.

Rapid Spanning Tree Protocol 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.
Chapter 5: Web-Based Management protocol allows for the duplicate links to be used in the event of a failure of the primary link. Once the Spanning Tree Protocol is configured and enabled, primary links are established and duplicated links are blocked automatically. The reactivation of the blocked links (at the time of a primary link failure) is also accomplished automatically without operator intervention. This automatic network reconfiguration provides maximum uptime to network users.
Chapter 5: Web-Based Management The communication between switches via BPDUs results in the following: • One switch is elected as the root switch. • The shortest distance to the root switch is calculated for each switch. • A designated switch is selected. This is the switch closest to the root switch through which packets will be forwarded to the root. • A port for each switch is selected. This is the port providing the best path from the switch to the root switch.
Chapter 5: Web-Based Management A port transitions from one state to another as follows: • From initialization (switch boot) to blocking. • From blocking to listening or to disabled. • From listening to learning or to disabled. • From learning to forwarding or to disabled. • From forwarding to disabled. • From disabled to blocking. Figure 5-38: STP Port State Transitions You can modify each port state by using management software.
Chapter 5: Web-Based Management RSTP Parameters RSTP Operation Levels The Switch allows for two levels of operation: the switch level and the port level. The switch level forms a spanning tree consisting of links between one or more switches. The port level constructs a spanning tree consisting of groups of one or more ports. The STP operates in much the same way for both levels.
Chapter 5: Web-Based Management The following are the user-configurable STP parameters for the port or port group level: Variable Description Default Value Port Priority A relative priority for each port –lower numbers give a higher priority and a greater chance of a given port being elected as the root port 128 Port Cost A value used by STP to evaluate paths – STP calculates path costs and selects the path with the minimum cost as the active path 200,000-100Mbps Fast Ethernet ports 20,000-1000Mbps
Chapter 5: Web-Based Management NOTE: The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration error will occur. Max. Age – The Max Age can be from 6 to 40 seconds. At the end of the Max Age, if a BPDU has still not been received from the Root Bridge, your Switch will start sending its own BPDU to all other Switches for permission to become the Root Bridge. If it turns out that your Switch has the lowest Bridge Identifier, it will become the Root Bridge.
Chapter 5: Web-Based Management the Priority setting, or influencing STP to choose a particular port to block using the Port Priority and Port Cost settings is, however, relatively straight forward. Figure 5-39: Before Applying the STA Rules In this example, only the default STP values are used.
Chapter 5: Web-Based Management The switch with the lowest Bridge ID (switch C) was elected the root bridge, and the ports were selected to give a high port cost between switches B and C. The two (optional) Gigabit ports (default port cost = 4) on switch A are connected to one (optional) Gigabit port on both switch B and C. The redundant link between switch B and C is deliberately chosen as a 100 Mbps Fast Ethernet link (default port cost = 19).
Chapter 5: Web-Based Management This page includes the following fields: Object Description RSTP mode: The user must enable the RSTP function first before configuring the related parameters. Priority (0-61440): 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.
Chapter 5: Web-Based Management Figure 5-42: RSTP Port Configuration interface This page includes the following fields: Object Description 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.
Chapter 5: Web-Based Management NOTE: Path cost "0" is used to indicate auto-configuration mode. When the short path cost method is selected and the default path cost recommended by the IEEE 8021w standard exceeds 65,535, the default is set to 65,535. By default, the system automatically detects the speed and duplex mode used on each port, and configures the path cost according to the values shown below.

Chapter 5: Web-Based Management QoS Configuration Quality of Service (QoS) is an advanced traffic prioritization feature that allows you to establish control over network traffic. QoS enables you to assign various grades of network service to different types of traffic, such as multi-media, video, protocolspecific, time critical, and file-backup traffic. QoS reduces bandwidth limitations, delay, loss, and jitter.
Chapter 5: Web-Based Management QoS Policy and Priority Type Here you can choose to use an 8-4-2-1 queuing scheme or a strict priority scheme, or select the priority type to configure QoS policy. Figure 5-49: QoS Configuration interface This page includes the following fields: Object Description Select the QoS policy rule.

Chapter 5: Web-Based Management IGMP Snooping Theory The Internet Group Management Protocol (IGMP) lets host and routers share information about multicast groups memberships. IGMP snooping is a switch feature that monitors the exchange of IGMP messages and copies them to the CPU for feature processing. The overall purpose of IGMP Snooping is to limit the forwarding of multicast frames to only ports that are a member of the multicast group.
Chapter 5: Web-Based Management Figure 5-55: Multicast flooding Figure 5-56: IGMP Snooping multicast stream control GE-DSH-73/DSH-82 and DSH-82-PoE User Manual 111
Chapter 5: Web-Based Management IGMP Versions 1 and 2 Multicast groups allow members to join or leave at any time. IGMP provides the method for members and multicast routers to communicate when joining or leaving a multicast group. IGMP version 1 is defined in RFC 1112. It has a fixed packet size and no optional data. The format of an IGMP packet is shown below: IGMP Message Format Octets 0 8 Type 16 31 Response Time Checksum Group Address (all zeros if this is a query).
Chapter 5: Web-Based Management IGMP version 2 introduces some enhancements such as a method to elect a multicast queried for each LAN, an explicit leave message, and query messages that are specific to a given group. The states a computer will go through to join or to leave a multicast group are shown below: Figure 5-57: IGMP State Transitions • IGMP Querier A router, or multicast-enabled switch, can periodically ask their hosts if they want to receive multicast traffic.
Chapter 5: Web-Based Management Figure 5-58: IGMP Configuration interface This page includes the following fields: Object Description IGMP Protocol: Enable or disable the IGMP protocol. IGMP Query: Enable or disable the IGMP query function. The IGMP query information will be displayed in IGMP status section. X-Ring X-Ring provides a faster redundant recovery than Spanning Tree topology. The action is similar to STP or RSTP, but the algorithms between them are not the same.
Chapter 5: Web-Based Management Figure 5-59: X-Ring Application In the network, it may have more than one X-Ring group. By using the coupling ring function, it can connect each X-Ring for the redundant backup. It can ensure the transmissions between two ring groups not to fail. The following figure is a sample of coupling ring application.
Chapter 5: Web-Based Management Figure 5-60: Coupling Ring Application Dual Homing Application Dual Homing function is to prevent the connection lose from between X-Ring group and upper level/core switch. Assign two ports to be the Dual Homing port that is backup port in the X-Ring group. The Dual Homing function only works when the XRing function is active. Each X-Ring group only has one Dual Homing port.
Chapter 5: Web-Based Management X-Ring Configuration The Managed Industrial Switch supports the function and interface for setting the switch as the ring master or not. The ring master can negotiate and place command to other switches in the X-Ring group. If there are 2 or more switches in master mode, the software will select the switch with lowest MAC address number as the ring master. The X-Ring master ring mode can be enabled by setting the X-Ring configuration interface.
Chapter 5: Web-Based Management ports as the member ports. 1st Ring Port is the working port and 2nd Ring Port is the backup port. When 1st Ring Port fails, the system will automatically upgrade the 2nd Ring Port to be the working port. To enable the couple ring function, tick the checkbox beside the Enable Couple Ring string label. Enable Couple Ring: Couple Port: Assign the member port which is connected to the other ring group.
Chapter 5: Web-Based Management connected to a switch port before making available any services offered by the switch or the LAN. Until the client is authenticated, 802.1X access control allows only Extensible Authentication Protocol over LAN (EAPOL) traffic through the port to which the client is connected. After authentication is successful, normal traffic can pass through the port.
Chapter 5: Web-Based Management the client. In this release, the Remote Authentication Dial-In User Service (RADIUS) security system with Extensible Authentication Protocol (EAP) extensions is the only supported authentication server; it is available in Cisco Secure Access Control Server version 3.0. RADIUS operates in a client/server model in which secure authentication information is exchanged between the RADIUS server and one or more RADIUS clients. • Switch (802.
Chapter 5: Web-Based Management authentication succeeds or fails. If the authentication succeeds, the switch port becomes authorized. The specific exchange of EAP frames depends on the authentication method being used. "Figure 5-64" shows a message exchange initiated by the client using the OneTime-Password (OTP) authentication method with a RADIUS server.
Chapter 5: Web-Based Management In contrast, when an 802.1X-enabled client connects to a port that is not running the 802.1X protocol, the client initiates the authentication process by sending the EAPOLstart frame. When no response is received, the client sends the request for a fixed number of times.

Chapter 7 Switch Operation Address Table The Switch is implemented with an address table. This address table composed of many entries. Each entry is used to store the address information of some node in network, including MAC address, port no, etc. This information comes from the learning process of Ethernet Switch. Learning When one packet comes in from any port, the Switch will record the source address, port no. And the other related information in address table.
Chapter 7: Switch Operation Store-and-Forward Store-and-Forward is one type of packet-forwarding techniques. A Store-andForward Ethernet Switching stores the incoming frame in an internal buffer, do the complete error checking before transmission. Therefore, no error packets occurrence, it is the best choice when a network needs efficiency and stability.
Chapter 8 Power Over Ethernet Overview What is PoE? Based on the global standard IEEE 802.3af, PoE is a technology for wired Ethernet, the most widely installed local area network technology adopted today. PoE allows the electrical power necessary for the operation of each end-device to be carried by data cables rather than by separate power cords. New network applications, such as IP Cameras, VoIP Phones, and Wireless Networking, can help enterprises improve productivity.
Chapter 8: Power Over Ethernet Overview PoE System Architecture The specification of PoE typically requires two devices: the Powered Source Equipment (PSE) and the Powered Device (PD). The PSE is either an End-Span or a MidSpan, while the PD is a PoE-enabled terminal, such as IP Phones, Wireless LAN, etc. Power can be delivered over data pairs or spare pairs of standard CAT-5 cabling.
Chapter 8: Power Over Ethernet Overview Figure 8-2 - Power Supplied over the Data Pins When to install PoE? Consider the following scenarios: • • You're planning to install the latest VoIP Phone system to minimize cabling building costs when your company moves into new offices next month.
Chapter 8: Power Over Ethernet Overview The PoE Provision Process While adding PoE support to networked devices is relatively painless, it should be realized that power cannot simply be transferred over existing CAT-5 cables. Without proper preparation, doing so may result in damage to devices that are not designed to support provision of power over their network interfaces. The PSE is the manager of the PoE process.
Chapter 8: Power Over Ethernet Overview The signature resistor lies in the PD's PoE front-end, isolated from the rest of the PD's circuitries till detection is certified. Classification Once a PD is detected, the PSE may optionally perform classification, to determine the maximal power a PD is to consume. The PSE induces 15.5-20.5 VDC, limited to 100 mA, for a period of 10 to 75 ms responded by a certain current consumption by the PD, indicating its power class.
Chapter 8: Power Over Ethernet Overview down power within 50 to 75 milliseconds, while limiting current drain during this period to protect the cabling infrastructure. Immediate voltage drop is avoided to prevent shutdown due to random fluctuations. Power Disconnection Scenarios The IEEE 802.3af standard requires that devices powered over Ethernet be disconnected safely (i.e. power needs be shut down within a short period of time following disconnection of a PD from an active port).

Appendix A: RJ-45 Pin Assignment 10/100Mbps, 10/100Base-TX When connecting your 10/100Mbps Ethernet Switch to another switch, a bridge or a hub, a straight or crossover cable is necessary. Each port of the Switch supports auto-MDI/MDI-X detection. That means you can directly connect the Switch to any Ethernet devices without making a crossover cable.
