Disadvantages of non-NMS switches: 1. Non-NMS switches have limited functions and are suitable for household or small-sized networks. 2. ARP protection is not supported. ARP attacks are not a virus, so almost all anti-virus software is helpless. But they are more like viruses-because they can cause slow communication, network paralysis, and information leakage

With the development of the communication industry and the advancement of information technology in the national economy, the Ethernet switch market has steadily increased. Ethernet features high performance, high flexibility, relatively simple, and easy to implement. Therefore, Ethernet technology has become the most important LAN networking technology today, and Ethernet switches have become the most popular swi
A prefecture-level government generally uses two networks to build an office network and a network of public services. Port network can be used hammer series of switches to form a office network, the whole network has the followin
copy, it can achieve high performance.The netmap mechanism of the Vale principle is the realization of Vale(Virtual Local Ethernet) is the core of high performance.Vale is actually a virtual local Ethernet switch. It gives each of its users (hypervisor or process) a virtual network interface (which can be accessed through the Netmap API). The core work is still on the Netmap backend side, which requires the logic of the switch to be added to the back
In general, asymmetric switches are mainly used in three environments: The network used in server/client mode, the connection between user switches, and the connection between switches and vrouters. For enterprises with tight pockets, using asymmetric switches to improve
Switch learning feature). Layer three switch: based on the traditional two layer switch, the network layer forwarding technology is adopted. We know that the host communication of different networks generally requires router forwarding, if only a local area network is divided into multiple subnets, inter-subnet communication using routers, then the communication efficiency between these subnets will be due
Theoretical learningproblem 1 : How does the switch work? By learning the computer MAC address of each interface, it realizes the data communication of each computer, and the routing table of the router is similar, the switch is realized by the Mac-port mapping table.problem 2 : Two layer switch, three layer switch, router difference? Two-layer switch: For switching, LAN, WAN switching onlyLayer Three switch: Also known as the routing switch, with the dual functions of routing and switching, onl
When purchasing a vswitch. In terms of performance, in addition to meeting the basic standards recommended by RFC2544, namely throughput, latency, and packet loss rate, as user services increase and applications increase, all packets in the same range are mapped by the server switch and transmitted between the user and the same server.
In general, asymmetric switches are mainly used in three environments: The netw
Asymmetric switches are easy to use in daily life. We can deploy an asymmetric switch on the server side. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things.
In general, asymmetric switches are mainly used in three environments: The network used in server/client mode, the connection between user
Asymmetric switches are still commonly used. So I have studied the working principle and network performance of asymmetric switches. I would like to share with you here, hoping to help you. For enterprises with tight pockets, using asymmetric switches to improve network perf
At present, backbone switches have been widely used in various fields. So I have studied the development status of backbone switches under the three-in-one network. I would like to share with you here and hope they will be useful to you. In a backbone switch, Ethernet technology can be used to conveniently implement VLANs. The number of VLANs supported by a backb
Asymmetric switches are worth learning a lot. Here we mainly introduce how asymmetric switches improve network performance. According to the speed of each port of a switch, there are two types of switches. Symmetric switches and non-symmetric
Asymmetric switches are worth learning. Here we will mainly introduce how to use asymmetric switches to improve network performance. Asymmetric switches are effective for enterprises that are unable to buy high-end switches, is a preferred switch device to improve
There are many things worth learning about edge switches. Here we mainly introduce a comprehensive description of the intelligent and performance of edge switches. If the edge devices of the network integrate QoS, rate limit, ACL, PBR, and sFlow into the hardware chip, the Intelligence will not affect the line rate forwarding performance of the basic layer 2 and
Recently opened the route for a new internet café, the Internet Café administrators ran to ask me, Internet cafes in the computer interconnection of the selected cable (hub) Good or switch good, Cisco's switch is not the best. People often say that only the right choice is not expensive. But how is the right choice? The common medium and small-sized network has two hundred or three hundred computers, many people reach thousands of units. They are conn
Asymmetric switches are still commonly used, so I have studied how to use asymmetric switches to improve network performance. Here I will share with you, hoping to help you. Vswitches can be divided into two types based on the speed of each port of a vswitch. Symmetric switches and non-symmetric
Cascade Extension
The Cascade extension mode is the most conventional and direct extension, and some of the older networks use hubs as cascaded devices. Because the hubs were already quite expensive, most enterprises could not choose a switch as a cascade device. That's because most team users are connected to a hub from a port level on the hub. In this way, the access ability is greatly improved, but due to some interference and human factors, so that the overall performance is very low, only
The configuration of network management switch has always been fascinated by many people, not only for the general users, but also for many professional users, but also as an important and basic indicator of the level of network management. this is mainly in two reasons, one is the vast majority of enterprises configured switches are desktop non-
GE switches are still commonly used. So I studied the standard for selecting Ge switches in Internet cafes. I would like to share with you here, hoping they will be useful to you. Internet cafes are an intensive and frequently-used entertainment place. In particular, some Internet cafes keep operating 24 hours a day. You can imagine how bad the working environment of sw
