2-1-3. Configuring the Management Agent of GEP-0950 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. 2-1-3-1. Configuring Management Agent of GEP-0950 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. The user interface for the last one is Management software dependent and does not cover here.
identifier (address) and host identifier (address). The former indicates the network where the addressed host resides, and the latter indicates the individual host in the network which the address of host refers to. And the host identifier must be unique in the same LAN. Here the term of IP address we used is version 4, known as IPv4. Network identifier Host identifier With the classful addressing, it divides IP address into three classes, class A, class B and class C.
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. According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks reserved and able to be used for extending internal network. We call it Private IP address and list below: Class A Class B Class C 10.0.0.0 --- 10.255.255.255 172.16.0.0 --- 172.31.255.255 192.168.0.

First, IP Address: as shown in the figure above, enter “192.168.1.1”, for instance. For sure, an IP address such as 192.168.1.x must be set on your PC. Second, Subnet Mask: as shown in the figure above, enter “255.255.255.0”. Any subnet mask such as 255.255.255.x is allowable in this case.
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 (DEC), Intel and Xerox (DIX) in 1980. In 1992, Grand Junction Networks unveiled a new high speed Ethernet with the same characteristic of the original Ethernet but operated at 100Mbps, called Fast Ethernet now.
IEEE 802.2 LLC Data Link Layer IEEE802.3 CSMA/CD MAC IEEE 802.3 PLS CS Physical Layer MII IEEE 802.3 MAU Coaxial/STP/UTP ANSI X3T9.5 PMD Fiber 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. 3-2.
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 SSAP address field identifies the specific services indicated by C/R bit (command or response). The DSAP and SSAP pair with some reserved values indicates some well-known services listed in the table below.
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. The MAC is belonged to Data Link Layer (Layer 2), the address is defined to be a 48-bit long and locally unique address.
PRE 7 - SFD 7 DA 6 SA 6 Type/Length 2 Data Pad bit if any 46-1500 FCS 4 Preamble (PRE) —The PRE is 7-byte long with alternating pattern of ones and zeros used to tell the receiving node that a frame is coming, and to synchronize the physical receiver with the incoming bit stream.
- 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. 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.
Ethernet MAC transmits frames in half-duplex and full-duplex ways. In halfduplex 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.

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. When the target is not busy and the PAUSE time is expired, it will send another PAUSE frame with zero time-to-wait to source device. After the source device receives the PAUSE frame, it will again transmit frames immediately.
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.

No VID is present and only user priority is present. 0x001: Default VID 0xFFF: Reserved Note: RIF is used in Token Ring network to provide source routing and comprises two fields, Routing Control and Route Descriptor.
3-5. How does a switch work? The switch is a layer 2 Ethernet Switch equipped with 8 Gigabit Ethernet ports and 1 optional module which support Gigabit Ethernet or 100M Ethernet. Each port on it is an independent LAN segment and thus has 9 LAN segments and 9 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.
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. The traffic can reach any station on the same LAN. Beyond this domain, the traffic cannot go without router’s help. This also implies that a LAN is limited.
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. Any traffic within VLAN 1 does not flow to VLAN 2 and others. This helps us configure the network easily according to the criteria needed, for example, financial, accounting, R&D and whatever you think it necessary.
Other VLAN technologies not mentioned above are MAC-based VLAN, IPbased 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). Normally, the maximal length of a tagged frame is 1522 bytes. 6 DA 802.
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. Each port can only be assigned a PVID. The default value for PVID is 1, the same as VID. Ingress filtering: The process to check a received packet and compare its VID to the VLAN membership of the ingress port.
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. In this mode, some VLAN or all VLANs use the same filtering database storing the membership information of the VLAN to learn or look up the membership information of the VLAN.
Name Marketing Service Sales Administration VID 2 3 4 1 Port Members 1,2 4,6,7 3,5 8,9 Next, assigns IP address to each VLAN. 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. Name Marketing Service Sales Administration VID 2 3 4 1 Network Address 10.1.2.0/24 10.1.3.0/24 10.1.4.0/24 10.1.1.0/24 Here we apply the subnet mask 255.255.255, and each VLAN is capable of supporting 254 nodes.
3-7. 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. This is the reason why now we have 802.3ad Link Aggregation Control Protocol (LACP). Why 802.3ad (LACP)? Network is varying.
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. Here station may be a host or a router.
