  • Page 23: Configuring Management Agent Of 24 Gigabit Web Smart Switch Through Ethernet Port

    • Managing 24 Gigabit Web Smart Switch through Ethernet Port Before you communicate with the switch, you have to finish first the configuration of the IP address or to know the IP address of the switch. Then, follow the procedures listed below.

  • Page 24: Ip Address Assignment

    Fig. 2-7 the Login Screen for 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.
  • Page 25 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.
  • Page 26 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 is 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.
  • Page 27 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 addresses matched.
  • Page 28 IP address, known as default router. Basically, it is a routing policy. For assigning an IP address to the switch, you just have to check what the IP address of the network will be connected with the switch. Use the same network address and append your host address to it.

  • Page 29: Typical Applications

    2-2. Typical Applications The 24 Gigabit Web Smart Switch implements 24 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.

  • Page 31: Chapter 3. Basic Concept And Management

    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.
  • Page 32 Data Link Layer IEEE802.3 CSMA/CD MAC IEEE 802.3 PLS Physical Layer IEEE 802.3 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.
  • Page 33 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.

  • Page 34: Media Access Control (Mac)

    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.
  • Page 35 Bit 47 1st byte 2nd byte 3rd byte OUI code 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).
  • Page 36 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.
  • Page 37 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.
  • Page 38 So this criterion should not exist at the present time and in the future. The switch’s Gigabit module supports only full-duplex mode. 64 bytes Fig. 3-4 Gigabit Ethernet Frame...
  • Page 39 Parameter 10Base value/LAN Max. collision domain DTE to 100 meters Max. collision domain with 2500 meters repeater Slot time 512 bit times Interframe Gap 9.6us AttemptLimit BackoffLimit JamSize 32 bits 1518 MaxFrameSize MinFrameSize BurstLimit Not applicable Table 3-4 Ethernet parameters for half duplex mode In full-duplex operation mode, both transmitting and receiving frames are processed simultaneously.

  • Page 40: Flow Control

    PAUSE operation can not be used to inhibit the transmission of MAC control frame. Normally, in 10Mbps and 100Mbps Ethernet, only symmetric flow control is supported. However, some switches (e.g. 24 Gigabit Web Smart Switch) support not only symmetric but asymmetric flow controls for the special application. In Gigabit Ethernet, both symmetric flow control and asymmetric flow control are supported.
  • Page 41 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.
  • Page 42 0x8100 at the location of the Length/Type field of the normal non-VLAN frame, it will interpret the received frame as a tagged VLAN frame. If this happens in a switch, the MAC will forward it, according to its priority and egress rule, to all the ports that is associated with that VID.

  • Page 43: How Does A Switch Work

    Micro-segmentation: To have a port of the switch connected to a single host is referred to as micro-segmentation. It has the following interesting characteristics. There is no need the access contention (e.g.Collision). They have their own access domain.
  • Page 44 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. And what’s more, when operating in full-duplex mode, the distance can reach farther than half duplex because it is not limited by the maximum propagation delay time (512 bits time).
  • Page 45 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.
  • Page 46 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.

  • Page 47: Virtual Lan

    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.
  • Page 48 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.
  • Page 49 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.
  • Page 50 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.
  • Page 51 Web Smart Switch, you can choose a VID for sharing filtering database in Shared VID field if you wish to use the existed filtering database. For a specified VLAN, when a MAC address is learned by a switch, VLAN will use this formation to make forwarding decision.
  • Page 52 VLAN existed, then floods the packet to all the ports the VLAN covers. If we plan to deploy four VLANs in an office and use a switch to partition them, we should check which ports belong to which VLAN first. Assuming a 24-port switch is applied.

  • Page 53: Link Aggregation

    Therefore, offering a tool with automatic recovery capability is necessary for an administrator. LACP is a protocol that allows a switch able to know whether its partner has the capability to co-setup a trunk between them.
  • Page 54 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. Link Aggregation, called port trunking sometimes, has two types of link configuration, including static port trunk and dynamic port trunk.
