1.4 LED Indicators and Connectors Before you use the Vigor device, please get acquainted with the LED indicators and connectors first. There are 8 Ethernet ports on the front panel of the switch. LED display area, locating on the front panel, contains an ACT, Power LED and 8 ports working status of the switch. LED Explanation LED PWR/SYS RJ 45 LNK/ACT for Ports 1 ~ 8 Color On (Green) Explanation The switch is powered on and runs normally. Off On (Green) The switch is not ready or is failed.
1.5 Hardware Installation Case 1: All switch ports are in the same local area network. Every port can access each other. (*The switch image is sample only.) If VLAN is enabled and configured, each node in the network that can communicate each other directly is bounded in the same VLAN area. Case 2: The same VLAN members can be at different switches with the same VID Desktop Installation 1. Install the switch on a level surface that can support the weight of the unit and the relevant components. 2.
Installing Network Cables Crossover or straight-through cable: All the ports on the switch support Auto-MDI/MDI-X functionality. Both straight-through or crossover cables can be used as the media to connect the switch with PCs as well as other devices like switches, hubs or router. Category 3, 4, 5 or 5e, 6 UTP/STP cable: To make a valid connection and obtain the optimal performance, an appropriate cable that corresponds to different transmitting/receiving speed is required.
1.5.1 Configuring the Management Agent of Switch Users can monitor and configure the switch through the following procedures. Configuring the Management Agent of VigorSwitch G1080 through the Ethernet Port. Web-based UI for the switch is an interface in a highly friendly way to configure and monitor the switch through the switch’s Ethernet port.
1.5.2 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 “192.168.1.224”, 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 VigorSwitch implements 8 Gigabit Ethernet TP ports with auto MDIX and two slots for the removable module supporting comprehensive fiber types of connection including LC and BiDi-LC SFP modules. The switch is suitable for the following applications.
It is a system wide basic reference connection diagram. This diagram demonstrates how the switch connects with other network devices and hosts.
Chapter 2: 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.
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.
