    User Manual 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 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.
  • Page 26 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 is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast.
  • Page 27 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 addresses matched.
  • Page 28 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.

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 User Manual IEEE 802.2 LLC Data Link Layer IEEE802.3 CSMA/CD MAC IEEE 802.3 PLS Physical Layer ANSI X3T9.5 PMD IEEE 802.3 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.
  • Page 33 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.

  • Page 34: Media Access Control (Mac)

    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.
  • Page 35 User Manual Bit 47 bit 0 1st byte 2nd byte 3rd byte 4th byte 5th byte 6th byte OUI code Serial number 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 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.
  • Page 37 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.
  • Page 38 User Manual Ethernet MAC transmits frames in half-duplex and full-duplex ways. In half- duplex 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.

  • Page 40: Flow Control

    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.
  • Page 41 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.
  • Page 42 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.

  • Page 43: How Does A Switch Work

    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.
  • Page 44 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.
  • Page 45 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. MAC address table When a packet is received on a port of switch, the switch first checks if the packet good or bad and extracts the source MAC address (SA) and destination...

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.

  • Page 47: Virtual Lan

    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.
  • Page 48 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.
  • Page 49 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.
  • Page 50 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.

  • Page 53: Link Aggregation

    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.
  • Page 54 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.
