They are the addresses with all zero’s and all one’s host number. For example, an IP address 128.1.2.128, what IP address reserved will be looked like?

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).

    3-3. Media Access Control (MAC) 3-3-1. 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.

It is created by the sending MAC and recalculated by the receiving MAC to check if the packet is damaged or not. How does a MAC work? The MAC sub-layer has two primary jobs to do: 1.
  • Page 35 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 37: Flow Control

    3-4. 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 38 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 40: How Does A Switch Work

    3-5. How does a switch work? The switch is a layer 2 Ethernet Switch equipped with 24 Gigabit Ethernet ports and 4 optional modules which support Gigabit Ethernet or 100M Ethernet. Each port on it is an independent LAN segment and thus has 26 LAN segments and 26 collision domains, contrast to the traditional shared Ethernet HUB in which all ports share the same media and use the same collision domain and thus limit the bandwidth utilization.
  • Page 41 Fig.3-6 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 42 Fig. 3-7 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 44: Virtual Lan

    3-6. 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 45 Fig. 3-9 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 46 Other VLAN technologies not mentioned above are MAC-based VLAN, IP- based VLAN and so on. Terminology Tagged Frame: A frame, carrying a tag field following the source MAC address, is four bytes long and contains VLAN protocol ID and tag control information composed of user priority, Canonical Format Indicator (CFI) and optional VLAN identifier (VID).
  • Page 47 Port VLAN Identifier: VLAN identifier of a port. It also can be referred to as PVID. When an untagged frame or a priority-tagged frame is received, the frame will be inserted the PVID of that port in the VLAN tag field. The frame with VID assigned by a port is called PVID.
  • Page 48 Independent VLAN Learning (IVL): It specifies the mode how to learn MAC address. For a specified VLAN, it will use an independent filtering database (FID) to learn or look up the membership information of the VLAN and decide where to go. Shared VLAN Learning (SVL): It specifies the mode how to learn MAC address.

Usually, we use 10.x.x.x as internal IP block. Because there are total four VLANs in the network, we must assign 4 IP blocks to each of them.
