Switch) performance directly affects the entire network. Therefore, it is not only necessary to understand the Switch parameters, but also helps you make better choices that meet your actual needs. Currently, the price of ATM switches remains high and is mainly used in backbone networks or wide area networks of large networks. Therefore, we will focus on Parameter Analysis of Ethernet switches.Selection of Backboard bandwidth and port RateThe port spe

The following article describes the parameter configuration of the Ethernet switch. The switch can be divided into Layer 2 switches, Layer 3 switches, and Layer 4 switches according to the working protocol layer, you can divide network-managed switches and non-managed switches based on whether the network management function is supported. Packet forwarding rate indicates the size of the packet forwarding capability of the switch. The Unit is generally

Let's talk about the installation process of the Ethernet card driver on ASUSN6 series computers under Fedora18. The computer is ASUSN6 series, and the ethernet card model is AtherosAR8161/8165. The driver for Linux is not found on the official website of this Nic. Search for the installation of the NIC driver on the Internet. The final conclusion is that alxEthernetdriver is installed. AlxEthernetdriver UR

TCP/IP supports a variety of link layer protocols, depending on the hardware used by the network, such as Ethernet, ring-based network, FDDI (Fiber Distributed Data interface, and fiber distributed data interface. The network based on different hardware uses different frames. Ethernet is the most widely used LAN technology today. Frame Structure of Ethernet V2.

The idea of iptables CLUSTER target and Ethernet switch, iptablesclusterThe air on the weekend was sultry, and the thought of it would never rain again. Every weekend, I will sum up all the things of the week, whether at work, in life, or on the way to and from work, or after reading, because it is no longer raining, I decided to have a good sleep on Saturday evening.When I explained the principles of vswitches and hubs to my colleagues, I thought tha

Ethernet is the undisputed overlord of the Internet world. It has been firmly occupying the territory of commercial office environments in recent years. The field of control and automation is also moving towards this open, standards-based technology. Do you think the cables used at the reception desk can also meet the demanding requirements of industrial process control and automation technology environments? In fact, COTS (Popular) 5e unshielded twis

hard to obtain using other methods. On the network, the most effective part of the listener is the gateway, router, firewall and other devices, which are usually operated by the network administrator. The most convenient way to use is to use an Ethernet network on any host that accesses the Internet. This is what most hackers do. 　　 Why can I listen on Ethernet? It is better to listen to the transmitted in

The following article is an effective description of the ethernet switch parameter configuration problem, the switch according to the work protocol layer can be divided into a second layer of switches, third-tier switches and layer fourth switch, according to whether or not to support the network management function can be divided into network-oriented switch and network-managed switch.

An Ethernet switch is a network device that can encapsulate and forward data packets based on MAC address recognition. The switch can "Learn" the MAC address and store it in the internal address table. By creating a temporary exchange path between the initiator of the data frame and the Target receiver, the data frame can directly reach the destination address from the source address. 1. The switch establishes a ing between the address and the switch

The Ethernet port of a vswitch has three link types: 1. Access user mode; 2. Trunk link Trunk mode; 3. Hybrid is similar to Trunk but more advanced than trunk; (1) Access Port: Only the Ethernet frame of the default vlan is allowed, that is, only one vlan can belong to. The Access port is tagged with a vlan after the Ethernet frame is received, and the vlan label

The Ethernet MAC address uniquely identifies each Ethernet device in the world. This article describes how to obtain the MAC address and how to change the MAC address. Obtain the MAC address In the command input window of the switch, enter "show mac-address-table" to obtain the MAC address table, for example:Switch # show mac-address-tableMac Address Table-------------------------------------------Vlan Mac

SetRERPAs a large-scale ring Ethernet deployment technology, Ethernet network protection solves problems such as weak protection capability of traditional data networks and long fault recovery time, it is an important technical choice and solution for carrier man construction. 1.

port location on the switch. Pairing Network cables in the LAN one by one.Finally, delete the files copied from the computer test and cancel the shared folder set on the computer in the LAN. Sort computer-related data, the port correspondence between the computer and the switch, and the "number tube" labeling records.In this way, you do not need to disconnect the LAN, check the computer connection status, and pair the network cable on the switch with a person, which is convenient and fast. Rela

Cisco device vlan, trunk, and Ethernet channel managementToday, we will introduce some common basic operations on cisco devices, such as creating VLANs, binding network cables, and using trunk and layer-3 switches. This is the topology of today: two three-layer switches, two PCs added with vlan10 and 20 respectively, and two three-layer switches with network redundancy. Finally, the communication between the two PCs is very simple, however, an experim

These days to complete a comparison of the Ethernet frame of the program (c), the teacher gave the Ethernet frame head and IP packet header structure, and the actual fetch to the packet format is the same.Data structure of Ethernet frame head:struct { char dest_mac[6]; Char src_mac[6]; Short Eth_type;} ethernet_header;The Eth_type fi
