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.

  • Page 40: How Does A Switch Work

    User Manual 3-4. How does a switch work? The switch is a layer 2 Ethernet Switch equipped with 24 Fast Ethernet ports and 2 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 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.

    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 51 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.
