It will take about 30 seconds, after that, the switch will flash all the LED once and automatically performs self-test and is in ready state. 1.5.2 Installing Optional SFP Fiber Transceivers to the switch If you have no modules, please skip this section. 1.5.3 Installing Chassis to a 19-Inch Wiring Closet Rail Caution: Allow a proper spacing and proper air ventilation for the cooling fan at both sides of the chassis.
The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters. Gigabit Ethernet TP network connection The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters. Cat. 5e is recommended. Cabling Requirements for 1000SX/LX SFP Module It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically, there are two categories of fiber, multi mode (MM) and single mode (SM).
Cat. 5 TP Wire: Fiber Cable: 11.12/m 10.10/m Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/m TP to fiber Converter: 56 Bit Time unit: 1ns (1sec./1000 Mega bit) Bit Time unit: 0.01s (1sec./100 Mega bit) Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within Round Trip Delay (bit times) in a half-duplex network segment (collision domain). For full-duplex operation, this will not be applied.
Case 2: Port-based VLAN -1 (*The switch image is sample only.) The same VLAN members could not be in different switches. Every VLAN members could not access VLAN members each other. The switch manager has to assign different names for each VLAN groups at one switch. Case 3: Port-based VLAN – 2 (*The switch image is sample only.) VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members. VLAN2 members could not access VLAN1 and VLAN3 members, but they could access VLAN4 members.
VLAN4 members could not access VLAN1 and VLAN3 members, but they could access VLAN2 members. Case 4: The same VLAN members can be at different switches with the same VID (*The switch image is sample only.
1.5.5 Configuring the Management Agent of Switch Users can monitor and configure the switch through the following procedures. Configuring the Management Agent of VigorSwitch G1260 through the 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 way.
1.5.6 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 communication. Its address structure looks is shown below. It is “classful” because it is split into predefined address classes or categories. Each class has its own network range between the network identifier and host identifier in the 32 bits address.
Class D and E: 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 10.0.0.0 --- 10.255.255.255 Class B 172.16.0.0 --- 172.31.255.
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. The following table shows the result. Prefix Length No. of IP matched No.
First, IP Address: as shown 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 above, enter “255.255.255.0”. Any subnet mask such as 255.255.255.x is allowable in this case. Note: The DHCP Setting is enabled in default.
1.6 Typical Applications The 24-Port L2 Managed Fast Ethernet Switch with 2 SFP Dual Media implements 24 Fast Ethernet TP ports with auto MDIX and 2 Gigabit dual media ports with SFP for removable module supported comprehensive fiber types of connection, including LC, BiDi LC for SFP.

Basic Concept and Management This chapter will tell you the basic concept of features to manage this switch and how they work. 2.1 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.
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 link layer is composed of both the sub-layers of MAC and MAC-client. Here MAC client may be logical link control or bridge relay entity.
(command or response). The DSAP and SSAP pair with some reserved values indicates some well-known services listed in the table below. LLC type 1 connectionless service, LLC type 2 connection-oriented service and LLC type 3 acknowledge connectionless service are three types of LLC frame for all classes of service. In Fig 3-2, it shows the format of Service Access Point (SAP). Please refer to IEEE802.2 for more details. 2.
The MAC is belonged to Data Link Layer (Layer 2), the address is defined to be a 48-bit long and locally unique address. Since this type of address is applied only to the Ethernet LAN media access control (MAC), they are referred to as MAC addresses. The first three bytes are Organizational Unique Identifier (OUI) code assigned by IEEE. The last three bytes are the serial number assigned by the vendor of the network device. All these six bytes are stored in a non-volatile memory in the device.
Source addresses (SA) - The SA field indicates the source node. The SA is always an individual address and the left-most bit in the SA field is always 0. 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, the number of bytes in the data field is equal to the Length/Type value, i.e. this field acts as Length indicator at this moment.
the data field and FCS field in turn. The followings summarize what a MAC does before transmitting a frame. 1. MAC will assemble the frame. First, the preamble and Start-of-Frame delimiter will be put in the fields of PRE and SFD, followed DA, SA, tag ID if tagged VLAN is applied, Ethertype or the value of the data length, and payload data field, and finally put the FCS data in order into the responded fields. 2. Listen if there is any traffic running over the medium. If yes, wait. 3.
Parameter value/LAN 10Base 100Base 1000Base Max. collision domain DTE to DTE 100 meters 100 meters for UTP 412 meters for fiber 100 meters for UTP 316 meters for fiber Max. collision domain with repeater 2500 meters 205 meters 200 meters Slot time 512 bit times 512 bit times 512 bit times Interframe Gap 9.6us 0.96us 0.
2.3 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.
Bits 11-0 VID (VLAN Identifier) 0x000: Null VID. 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. 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.
collision. The arbitrator will arbitrate who should gain the media. The arbitrator is a distributed mechanism in which all stations contend to gain the media. Please refer to “What’s the Ethernet” for more details. In the figure listed below, assumed in half duplex, you will see some ports of the switch are linked to a shared HUB, which connects many hosts, and some ports just are individually linked to a single host.
The switch port can run at different speed, such as 10Mbps, 100Mbps or 1000Mbps. A shared hub cannot afford this. Extended Distance Limitations: Traffic aggregation is to aggregate the bandwidth of more than one port and treat it as a single port in the LAN. This single port possesses the features of a normal port but loading balance. This is a great feature for the port needing more bandwidth but cannot afford paying much cost for high bandwidth port. (* The switch image is sample only.
the traffic using that entry has yet come for a while. If this time period is more than the aging time, the entry will be marked invalid. The vacancy is now available for other new MAC. Both learning and forwarding are the most important functions in a switch. Besides that, VLAN can be one of the rules to forward the packet. There are ingress rule and egress rule applied.
In the figure above, all stations are within the same broadcast domain. For these stations, it is obviously that the traffic is getting congested while adding more stations on it. With the more and more users joining the LAN, broadcast traffic will rapidly decrease the performance of the network. Finally, the network may get down. (* The switch image is sample only.) Now we apply VLAN technology to configure the system shown as the figure above.
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. You can also easily move a user to a different location or join a new user somewhere in the building to VLAN. Without VLAN, it is very hard to do. Basically, VLAN can afford offering at least 3 benefits: move and change users, reduce broadcast traffic and increase performance, Security.
Untagged frame: An Ethernet frame carries no VLAN tag information. VLAN Identifier: Also referred to as VID. It is used to identify a member whether it belongs to the VLAN group with the VID. The assignable number is 1- 4094. If VID=0, the tagged frame is a priority packet. Both the value of 0 and 4095 also cannot be assigned in VLAN management. Port VLAN Identifier: VLAN identifier of a port. It also can be referred to as PVID.
untagged for a transmitted packet. When a packet is transmitted out, the VLAN bridge checks the port’s egress list. If the VLAN of the packet is on the egress list of the port on which the packet transmits out, the packet will be transmitted with the priority accordingly. If enabled, an egress port will transmit out a tagged packet if the port is connected to a 802.1Q-compliant device. If an egress port is connected to a non-802.
If we plan to deploy four VLANs in an office and use a switch to partition them, we should check which ports belong to which VLAN first. Assuming a 24-port switch is applied. Name VID Port Members Marketing 2 1,2,3,4,5 Service 3 6,7,20,21,22 Sales 4 8,9,10,11,12,13,14,15,16 Administration 1 17,18,19,23,24 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.

The apparatus comprises a switch having said plurality of ports, each port configured as a protected port or a non-protected port. An address table memory stores an address table having a destination address and port number pair.
3.5 Aggregation The Aggregation (Port Trunking) Configuration is used to configure the settings of Link Aggregation. You can bundle ports by same speed, MAC, and full duplex to be a single logical port, thus the logical port can aggregate the bandwidth of these ports. This means you can apply your current Ethernet equipments to build the bandwidth aggregation.
3.6 802.1X 802.1x port-based network access control provides a method to restrict users to access network resources via authenticating user’s information. This restricts users from gaining access to the network resources through a 802.1x-enabled port without authentication. If a user wishes to touch the network through a port under 802.1x control, he (she) must firstly input his (her) account name for authentication and waits for gaining authorization before sending or receiving any packets from a 802.
While in the authentication process, the message packets, encapsulated by Extensible Authentication Protocol over LAN (EAPOL), are exchanged between an authenticator PAE and a supplicant PAE. The Authenticator exchanges the message to authentication server using EAP encapsulation. Before successfully authenticating, the supplicant can only touch the authenticator to perform authentication message exchange or access the network from the uncontrolled port.
1. At the initial stage, the supplicant A is unauthenticated and a port on switch acting as an authenticator is in unauthorized state. So the access is blocked in this stage. 2. Initiating a session. Either authenticator or supplicant can initiate the message exchange. If supplicant initiates the process, it sends EAPOL-start packet to the authenticator PAE and authenticator will immediately respond EAP-Request/Identity packet. 3.
