User Manual 2. Installation 2-1. Starting Gigabit Web Smart Switch Up This section will give users a quick start for: - Hardware and Cable Installation - Management Station Installation - Software booting and configuration 2-1-1.
User Manual • TP Port and Cable Installation In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used. It means you do not have to tell from them, just plug it. Use Cat.
User Manual 2-1-2-1. Cabling Requirements for TP Ports For Fast Ethernet TP network connection The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters. Gigabit Ethernet TP network connection The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters. Cat. 5e is recommended. 2-1-2-2. Cabling Requirements for 1000SX/LX SFP Module It is more complex and comprehensive contrast to TP cabling in the fiber media.
User Manual 2-1-2-3. Sw itch Cascading in Topology • Takes the Delay Time into Account Theoretically, the switch partitions the collision domain for each port in switch cascading that you may up-link the switches unlimitedly. In practice, the network extension (cascading levels & overall diameter) must follow the constraint of the IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations are the timing requirement from physical signals defined by 802.
User Manual Case1: All switch ports are in the same local area network. Every port can access each other (See Fig. 2-2). Fig. 2-2 No VLAN Configuration Diagram If VLAN is enabled and configured, each node in the network that can communicate each other directly is bounded in the same VLAN area. Here VLAN area is defined by what VLAN you are using. The switch supports both port-based VLAN and tag-based VLAN. They are different in practical deployment, especially in physical location.
User Manual Case 2b: Port-based VLAN (See Fig.2-4). Fig. 2-4 Port-based VLAN Diagram 1. VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members. 2. VLAN2 members could not access VLAN1 and VLAN3 members, but they could access VLAN4 members. 3. VLAN3 members could not access VLAN1, VLAN2 and VLAN4. 4. VLAN4 members could not access VLAN1 and VLAN3 members, but they could access VLAN2 members. Case3a: The same VLAN members can be at different switches with the same VID (See Fig. 2-5). Fig.
User Manual 2-1-3. Configuring the Management Agent of Gigabit Web Sm art Sw itch In the way of web, user is allowed to startup the switch management function. Users can use any one of them to monitor and configure the switch. You can touch them through the following procedures.
User Manual 2-1-3-1. Configuring Management Agent of Gigabit Web Smart Switch through Ethernet Port There are two ways to configure and monitor the switch through the switch’s Ethernet port. They are Web browser and SNMP manager. The user interface for the last one is NMS dependent and does not cover here. We just introduce the first type of management interface. Web-based UI for the switch is an interface in a highly friendly way. 16 Gigabit Web Smart Switch Def ault IP Setting: IP = 192.168.1.
User Manual Fig. 2-7 the Login Screen f or Web 2-1-4. IP Address Assignment For IP address configuration, there are three parameters needed to be filled in. They are IP address, Subnet Mask, Default Gateway and DNS. IP address: The address of the network device in the network is used for internetworking communication. Its address structure looks is shown in the Fig. 2-8. It is “classful” because it is split into predefined address classe s or categories.
User Manual With the classful addressing, it divides IP address into three classes, class A, class B and class C. The rest of IP addresses are for multicast and broadcast. The bit length of the network prefix is the same as that of the subnet mask and is denoted as IP address/X, for example, 192.168.1.0/24. Each class has its address range described below. Class A: Address is less than 126.255.255.255. There are a total of 126 networks can be defined because the address 0.0.0.
User Manual Class D and E: Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast. See also RFC 1112. Class E i s a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast. According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks reserved and able to be used for extending internal network. We call it Private IP address and list below: Class A Class B Class C 10.0.0.0 --- 10.255.255.255 172.16.0.0 --- 172.
User Manual In this diagram, you can see the subnet mask with 25-bit long, 255.255.255.128, contains 126 members in the sub-netted network. Another is that the length of network prefix equals the number of the bit with 1s in that subnet mask. With this, you can easily count the number of IP addresse s matched. The following table shows the result. Prefix Length No. of IP matched No.
User Manual For different network applications, the subnet mask may look like 255.255.255.240. This means it is a small network accommodating a maximum of 15 nodes in the network. Default gateway: For the routed packet, if the destination is not in the routing table, all the traffic is put into the device with the designated IP address, known as default router. Basically, it is a routing policy.
User Manual 2-2. Typical Applications The Gigabit Web Smart Switch implements Gigabit Ethernet TP ports with auto MDIX and two slots for the removable module supporting comprehensive fiber types of connection, including LC and BiDi-LC SFP modules. For more details on the specification of the switch, please refer to Appendix A. The switch is suitable for the following applications. Central Site/Remote site application is used in carrier or ISP (See Fig.

User Manual 3. Basic Concept and Management This chapter will tell you the basic concept of features to manage this switch and how they work. 3-1. What’s the Ethernet Ethernet originated and was implemented at Xerox in Palo Alto, CA in 1973 and was successfully commercialized by Digital Equipment Corporation (DEC), Intel and Xerox (DIX) in 1980.
User Manual IEEE 802.2 LLC Data Link Layer IEEE802.3 CSMA/CD MAC IEEE 802.3 PLS CS Physical Layer MII ANSI X3T9.5 PMD IEEE 802.3 MAU Fiber Coaxial/STP/UTP This above diagram shows the Ethernet architecture, LLC sub-layer and MAC sub-layer, which are responded to the Data Link layer, and transceivers, which are responded to the Physical layer in OSI model. In this section, we are mainly describing the MAC sub-layer.
User Manual Table 3-1 LLC Format The table 3-1 is the format of LLC PDU. It comprises four fields, DSAP, SSAP, Control and Information. The DSAP address field identifies the one or more service access points, in which the I/G bit indicates it is individual or group address. If all bit of DSAP is 1s, it’s a global address. The SSAP address field identifies the specific services indicated by C/R bit (command or response).
User Manual Fig. 3-2 SAP Format 3-2. Media Access Control (MAC) MAC Addressing Because LAN is composed of many nodes, for the data exchanged among these nodes, each node must have its own unique address to identify who should send the data or should receive the data. In OSI model, each layer provides its own mean to identify the unique address in some form, for example, IP address in network layer.
User Manual Bit 47 1st byte 2nd byte OUI code 3rd byte 4th byte 5th byte Serial number bit 0 6th byte Table 3-3 Ethernet MAC address The first bit of the first byte in the Destination address (DA) determines the address to be a Unicast (0) or Multicast frame (1), known as I/G bit indicating individual (0) or group (1). So the 48-bit address space is divided into two portions, Unicast and Multicast. The second bit is for global-unique (0) or locally-unique address.
User Manual Destination address (DA) — The DA field is used to identify which network device(s) should receive the packet. It is a unique address. Please see the section of MAC addressing. Source addresses (SA) — The SA field indicates the source node. The SA is always an individual address and the left-most bit in the SA field is always 0. Length/Type — This field indicates either the number of the data bytes contained in the data field of the frame, or the Ethernet type of data.
User Manual How does a MAC work? The MAC sub-layer has two primary jobs to do: 1. Receiving and transmitting data. When receiving data, it parses frame to detect error; when transmitting data, it performs frame assembly. 2. Performing Media access control. It prepares the initiation jobs for a frame transmission and makes recovery from transmission failure.
User Manual Ethernet MAC transmits frames in half-duplex and full-duplex ways. In halfduplex operation mode, the MAC can either transmit or receive frame at a moment, but cannot do both jobs at the same time. As the transmission of a MAC frame with the half-duplex operation exists only in the same collision domain, the carrier signal needs to spend time to travel to reach the targeted device.
User Manual Parameter value/LAN Max. collision domain DTE to DTE Max. collision domain with repeater Slot time Interframe Gap AttemptLimit BackoffLimit JamSize MaxFrameSize MinFrameSize BurstLimit 10Base 100 meters 100Base 1000Base 100 meters for UTP 100 meters for UTP 412 meters for fiber 316 meters for fiber 2500 meters 205 meters 200 meters 512 bit times 9.6us 16 10 32 bits 1518 64 Not applicable 512 bit times 0.96us 16 10 32 bits 1518 64 Not applicable 512 bit times 0.
User Manual 3-3. Flow Control Flow control is a mechanism to tell the source device stopping sending frame for a specified period of time designated by target device until the PAUSE time expires. This is accomplished by sending a PAUSE frame from target device to source device. When the target is not busy and the PAUSE time is expired, it will send another PAUSE frame with zero time-to-wait to source device. After the source device receives the PAUSE frame, it will again transmit frames immediately.
User Manual Frame Reception In essence, the frame reception is the same in both operations of half duplex and full duplex, except that full-duplex operation uses two buffers to transmit and receive the frame independently. The receiving node always “listens” if there is traffic running over the medium when it is not receiving a frame.
User Manual What if a VLAN tagging is applied? VLAN tagging is a 4-byte long data immediately following the MAC source address. When tagged VLAN is applied, the Ethernet frame structure will have a little change shown as follows. Only two fields, VLAN ID and Tag control information are different in comparison with the basic Ethernet frame. The rest fields are the same.
User Manual The maximum length of the extension is equal to the quantity (slotTime minFrameSize). The MAC continues to monitor the medium for collisions while it is transmitting extension bits, and it will treat any collision that occurs after the threshold (slotTime) as a late collision. 3-4. How does a switch work? The switch is a layer 2 Ethernet Switch equipped with 16 Fast Ethernet ports and 2 optional modules which support Gigabit Ethernet or 100M Ethernet.
User Manual Fig.3-5 Collision Domain Extended Distance Limitations: The diameter of a half-duplex LAN segment is determined by its maximum propagation delay time. For example, in 10M LAN, the most distance of a LAN segment using yellow cable is 2500 meters and 185 meters when using coaxial cable. The switch with its per port per collision domain can extend the distance like a bridge does.
User Manual Fig. 3-6 How does a switch operate? A Layer 2 switch uses some features of the Data Link layer in OSI model to forward the packet to the destination port(s). Here we introduce some important features of a switch and how they work.
User Manual Mac address aging There is a field in MAC address table used to put the entry’s Age time which determines how long a MAC entry can reside in a switch. The age time is refreshed when a packet with that SA. Usually, the age time is programmable. Transmission schedule In most layer 2 switches, the QoS is supported. QoS in a switch must associate a transmission schedule to transmit the packet. This function is much to do with the priority level a packet has.
User Manual 3-5. Virtual LAN What is a VLAN? It is a subset of a LAN. Before we discuss VLAN, we must understand what LAN is. In general, a LAN is composed of different physical network segments bridged by switches or bridges which attach to end stations in the same broadcast domain. The traffic can reach any station on the same LAN. Beyond this domain, the traffic cannot go without router’s help. This also implies that a LAN is limited.
User Manual Fig. 3-8 Now we apply VLAN technology to configure the system shown as the figure above. We can partition the users into the different logical networks which have their own broadcast domain. The traffic will not disturb among these logical networks. The users 1x (x denotes a ~ d) are members of VLAN 1. Any traffic within VLAN 1 does not flow to VLAN 2 and others.
User Manual There are many types of VLAN applied. Most popular is port-based VLAN, tag-based VLAN and protocol-based VLAN. Port-based VLAN Some physical ports are configured as members of a VLAN. All stations attached on these ports can communicate with each other. Tag-based VLAN It identifies the membership by VLAN ID, no matter where the packet comes from. It is also referred to as 802.1Q VLAN.
User Manual VLAN-tagged frame: An Ethernet frame, carrying VLAN tag field, contains VLAN identification without the value of 0 and 4095, and priority information. Priority-tagged frame: An Ethernet frame, carrying VLAN tag field, contains VLAN identification with the value of 0 and priority information. Untagged frame: An Ethernet frame carries no VLAN tag information. VLAN Identifier: Also referred to as VID. It is used to identify a member whether it belongs to the VLAN group with the VID.
User Manual Ingress Rule: Each packet received by a VLAN-aware bridge will be classified to a VLAN. The classification rule is described as follows. 1. If the VID of the packet is null VID (VID=0)or this packet is an untagged packet: If there are still some other ways(e.g. protocol, MAC address, application, IPsubnet, etc.
User Manual How does a Tagged VLAN work? If the ingress filtering is enabled and when a packet is received, VLAN bridge will first check if the VID of the packet presents. 1). If the packet has a non-zero VID, VLAN bridge will apply this VID as the VLAN ID of the packet in the network. 2). For a packet with null tag or no VLAN tag, if VLAN bridge provides rules to decide its VID, then apply this VID to the packet.
User Manual 3-6. Link Aggregation Basically, Link Aggregation is to aggregate the bandwidth of more than one port to an assigned logical link. This highly increases total bandwidth to the targeted device. There is more than one Link Aggregation technology in many vendors’ switch products already, which may cause the problem of interoperability. This is the reason why now we have 802.3ad Link Aggregation Control Protocol (LACP). Why 802.3ad (LACP)? Network is varying.
User Manual Terminology Link Aggregation: It is a method to have multiple physical links with the same media and speed bundled to be a logical link forming a Link Aggregation Group with a group ID. With the viewpoint of MAC client, each Link Aggregation Group is an independent link. There are three cases of link used in the network, which are switch to switch, switch to station and station to station. Here station may be a host or a router.
User Manual 4. Operation of Web-based Management This chapter instructs you how to configure and manage the 16 Gigabit Web Smart Switch through the web user interface it supports, to access and manage 14 10/100/1000Mbps TP Port and 2 Gigabit TP/SFP Fiber dual media port. The switch provides 14 fixed Gigabit Ethernet TP ports and 2 optional Gigabit dual media ports supporting either fiber or TP media.

User Manual 4-2-3. VLAN Mode Configuration The switch supports Port-based VLAN and Tag-based VLAN (802.1q). Support 16 active VLANs and VLAN ID 1~4094. VLAN configuration is used to partition your LAN into small ones as your demand. Properly configuring it, you can gain not only improving security and increasing performance but greatly reducing VLAN management.
User Manual Metro Mode: The Metro Mode is a quick configuration VLAN environment method on Port-based VLAN. It will create 14 or 15 Port-based VLAN groups. Fig.
User Manual Up-link Port: This function is enabled only when metro mode is chosen in VLAN mode. 15: Except Port 15, each port of the switch cannot transmit packets with each other. Each port groups a VLAN with Port 15, thus, total 15 groups consisting of 2 members are formed. 16: Except Port 16, each port of the switch cannot transmit packets with each other. Each port groups a VLAN with Port 16, thus, total 15 groups consisting of 2 members are formed.
User Manual 4-2-4. VLAN Group Configuration Function name: VLAN Group Configuration Function description: It shows the existed information of VLAN Groups List and maintains them, i.e. modify and delete one of them. User also can add a new VLAN group by inputting a new VLAN name and VLAN ID. If you are in port-based VLAN, it will just show the ID、Description、Member of the existed port-based VLAN group.
User Manual Fig. 4-7 Add Group: Create a new port-based VLAN or tag-based VLAN, which depends on the VLAN mode you choose in VLAN mode function. Fig.

The range of VID number is from 1 to 4094. User also can choose ingress filtering rules to each port. There are two ingress filtering rules which can be applied to the switch. The Ingress Filtering Rule 1 is “forward only packets with VID matching this port’s configured VID”. The Ingress Filtering Rule 2 is “drop untagged frame”.
User Manual Untag State: If you checked this function for a Tag out port, the packet form this port may be tag out. But, the packet would be untag out if the VID of its tag is the same as the value of ”Untag VID” while Untag VID state is Enable. Untag VID: Valid range is 0~4094. Fig.
User Manual 4-2-6. Aggregation Configuration The Aggregation (Port Trunking) Configuration is used to configure the settings of Link Aggregation. You can bundle more than one port with the same speed, full duplex and the same MAC to be a single logical port, thus the logical port aggregates the bandwidth of these ports. This means you can apply your current Ethernet equipments to build the bandwidth aggregation.
User Manual 4-2-7. Mirror Configuration Function name: Mirror Configuration Function description: Mirror Configuration is to monitor the traffic of the network. For example, we assume that Port A and Port B are Sniffer Port and Source Port respectively, thus, the traffic passed by Port B will be copied to Port A for monitoring.
