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 22 Chapter 3: Installation Class B: A Class B IP address ranges between 128.0.0.0 and 191.255.255.255. Each class B network has a 16-bit network prefix followed by a 16-bit host address. There are 16,384 (2 )/16 networks able to be defined with a maximum of 65534 (2 –2) hosts per network.

  • Page 30: Ethernet Frame Format

    Chapter 4: Basic Concepts and Management The first three bytes are Organizational Unique Identifier (OUI) codes assigned by IEEE. The last three bytes are the serial number assigned by the vendor of the network device. All six bytes are stored in non-volatile memory in the device. Their format is shown in Table 4-3.
  • Page 31 Chapter 4: Basic Concepts and Management • 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. If the value of first two bytes is less than or equal to 1500 in decimal notation, the number of bytes in the data field is equal to the Length/Type value, that is, this field acts as a Length indicator at this moment.
  • Page 32 Chapter 4: Basic Concepts and Management 4. During the transmission, the MAC keeps monitoring the status of the medium. If no collision happens until the end of the frame, it transmits successfully. If there is a collision, the MAC will send the patterned jamming bit to guarantee the collision event is propagated to all involved network devices, then wait for a random period of time, called back off time.

  • Page 34 Chapter 4: Basic Concepts and Management Inter-frame Gap time After the end of a transmission, if a network node is ready to transmit data out and if there is no carrier signal on the medium at that time, the device will wait for a period of time known as an inter-frame gap time to clear and stabilize the medium, as well as to have the jobs ready, such as adjusting buffer counter, updating counter, and so on, in the receiver site.

When tagged VLAN is applied, the Ethernet frame structure will change slightly. Collision domain 2 Collision domain 1 Collision Collision...
  • Page 36 Chapter 4: Basic Concepts and Management When MAC parses the received frame and finds a reserved special value 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 associated with that VID.

  • Page 37: How Does A Switch Work

    4.5 How Does a Switch Work? The LGB2118A switch is a layer 2 Ethernet Switch equipped with (16) TP Gigabit Ethernet ports and (2) slots for optional SFP fiber modules. The LGB2124A switch has (20) TP ports and (4) slots for optional TP/SFP combo modules. Each port on the switch is an independent LAN segment and thus has 26 LAN segments and 26 collision domains, in 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 use.

User priority is defined from 7–0. 0 is the lowest priority. CFI: Canonical Format Indicator is 1 bit long. It encapsulates a token ring packet so it can travel across the Ethernet. Usually, it is set to 0.
  • Page 42 Chapter 4: Basic Concepts and Management 2. If the VID is not a null VID (VID is not equal to 0), then use the value to classify the VLAN group. Egress Rule: An egress list is used to make the tagging and forwarding decision on an outgoing port. It specifies the VLANs whose packets can be transmitted out and specifies if the packet should be tagged or not.

  • Page 43: Link Aggregation (Lgb2118A Only)

    10.1.1.0/24 Here we apply the subnet mask 255.255.255, and each VLAN can support 254 nodes. 4.7 Link Aggregation (LGB2118A Only) Link Aggregation combines the bandwidth of more than one port to an assigned logical link. This increases total bandwidth to the targeted device.
  • Page 44 Chapter 4: Basic Concepts and Management There are also some constraints when applying LACP: 1. LACP does not support inter-switch bandwidth aggregation. 2. The ports aggregated must operate in full-duplex mode. 3. The ports in the same Link Aggregation Group must operate at the same speed, for example, all 100 Mbps or all 1000 Mbps. You cannot aggregate a 1000 Mbps port and two 100 Mbps ports for a 1.2 Gbps trunk port.
