11 2-1-2-3. Switch Cascading in Topology • Takes the Delay Time into Account Theoretically, the switch partitions the collision domain for each port in switch cascading that you may up-link the switches unlimitedly. In practice, the network extension (cascading levels & overall diameter) must fo...
12 Case1: All switch ports are in the same local area network. Every port can access each other (See Fig. 2-2). If VLAN is enabled and configured, each node in the network that can communicate each other directly is bounded in the same VLAN area. Here VLAN area is defined by what VLAN you are using....
14 2-1-3. Configuring the Management Agent of 24-Port GbE Web Smart Switch In the way of web, user is allowed to startup the switch management function. Users can use any one of them to monitor and configure the switch. You can touch them through the following procedures. Section 2-1-3-1: Configurin...
15 2-1-3-1. Management through Ethernet Port There are two ways to configure and monitor the switch through the switch’s Ethernet port. They are Web browser and SNMP manager. We just introduce the first type of management interface. Web-based UI for the switch is an interface in a highly friendly wa...
16 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 commu...
19 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...
20 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 wi...
21 2-2. Typical Applications The 24-Port GbE Web Smart Switch provides auto MDIX on its TP ports and supports fiber types like: LC and BiDi SFP for removable modules on its four slots. For more details on the specification of the switch, please refer to Appendix A. The switch is suitable for the fol...
23 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...
24 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. Logical Link Control (LLC) Data l...
25 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. The SS...
27 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...
28 - 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-...
29 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 transmi...

34 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 compariso...
39 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. The traffic can reach an...
46 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 ...
