Backbone switches are still commonly used. So I studied the development status of backbone switches and shared them here. I hope they will be useful to you. At present, backbone switches have been widely used in various fields. So I have studied the

The core switch is still quite common, So I studied the actual functions of the core switch Display command. Here I will share it with you and hope it will be useful to you. In the LAN operating environment, the working status of core switch

The Cisco Ethernet switch is also available on the Interface 3 ~ After about four years, his own drivers are constantly updated, and his stability and security have also changed. In China, as an important part of network infrastructure, vswitches

The soft switch technology is one of the most important and critical speech service aggregation node technologies in the Next Generation Network. Let's take a look at the various links and skills of the soft switch and give us some insights and

All sites in a LAN are connected to a hub or LAN switch. A switched hub or LAN switch has a switching function. Based on the communication properties, each port of the switch can use different data rates. Therefore, sites can be deployed at

Cisco switches are currently the main force in the Exchange industry, and their products are doing very well in the market. Here we mainly analyze some usage skills of Cisco switches. As a network manager, it is inevitable to debug switches

In our daily life, we can feel the differences between the two methods, obviously we can feel the superiority of the two-lane exchange method, it means that a vswitch with good performance can process the same speed as a poor vswitch. For a vswitch,

VLANIt is a protocol proposed to solve Ethernet broadcast problems and security. It adds VLAN headers Based on Ethernet frames and divides users into smaller working groups using VLAN IDs, restrict mutual access between users in different working

TrunkTo configure a port, follow these steps: One Networking requirement: 1. SwitchA and SwitchB are interconnected with trunk. Mutual access is allowed between PCs with the same VLAN. Mutual access is prohibited between PCs with different VLANs; 2.

Hub HUB). It is a device that works on the physical layer. Because it only works on the physical layer, it does not care about or care about the layers involved in the OSI, its working process is: when a packet is received from a port, the packet is

Switch Switching Mode ExchangeMachineYou can exchange data in the following three ways: 1) pass-through: A straight-through Ethernet switch can be understood as a line matrix telephone switch that is crossly And crossly between ports. When a packet

L2 Switch The development of L2 Switch Technology is relatively mature. L2 Switch is a data link layer device that can identify the MAC address information in the data packet and forward it according to the MAC address, the MAC addresses and

Basic switch: basic functions of LAN switches 1. Basic vswitch concepts A lan switch is a network device that works on the data link layer. The switch filters and forwards data frames based on the MAC address in the port data frame. It is a network

Switch Classification 1: According to the LAN standard supported by the switch ① Ethernet switches are the most popular ② FDDI switch Optical Fiber Distributed Data Interface) ③ Asynchronous transmission mode of an ATM Switch) ④ Wildcard ring switch

Image PortSimply putVswitchOne copy of the traffic of multiple) Port source ports is completely copied and sent from another port destination port, so that the network administrator can analyze the traffic of the source port from the target port to

Cisco switch network configuration: Gateway redundancy server load balancing Virtual Router Redundancy protocol (vrouter Redundancy protocal, VRRP): Redundancy can be used on various devices. Hot Backup Router Protocol HSRP): cisco proprietary

It is very useful to know some methods for configuring CISCO router parameters. Here we mainly analyze how to configure CISCO router parameters in a UNIX operating system. In network applications, the most common application is file transmission.

Many people may not have a special understanding of vrouters and vswitches. So I have studied the comprehensive description of vrouters and vswitch simulators. I will share with you here, hoping to help you. Cisco certification has always been

At present, enterprise routers have become the best choice for small and medium-sized enterprises. Here we mainly analyze the key factors for the success or failure of Enterprise router management. In vro management, some configurations do not have

There are a lot of users using CISCO routers. Maybe many people still don't know the actual application of the access list in CISCO routers. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more
