From the data, we can see that the bandwidth of the Ethernet switch stack is dozens of times the speed of the switch port, which can effectively improve the network performance, when the number of ports that a single switch can provide is insufficient to meet the requirements of the
August 2012, the current network use of a ZTE 2826 switch can not remote Telnet logon situation, ping switch network management IP address serious packet loss. The process is probably as follows:

The switch occupies an important position in the enterprise network, which is usually the core of the whole network. In this era of hacker intrusion and virus-ridden network, as the core of the switch is also taken for granted a part of the responsibility of
In many cases, wireless technology is not a single use. The combination of wireless technology and other network devices is the current trend. How can we control interference with signals on networks?
There is no interference in the signal and seamless network switching, so there is a wireless network connection method that can achieve this effect. It is also a p
VLAN overviewVirtual LANs are a logical group of users who are linked on physical devices that are not subject to physical location restrictions.Reference VLAN:The switch divides the conflict domain, but cannot divide the broadcast domain, as the number of switch ports increases, the broadcast in the network increases, the ne
Set the network backbone and the layer-3 Switch required to connect to the subnet. Let's talk about how to set the layer-3 switch. The following three-tier switch settings are indispensable for the network backbone, and the three-tier sw
It should be said that gigabit network switches have become the first choice for medium and large enterprises. A high-performance switch not only improves the speed of devices, but also adds a lot of functions. The new intelligence of GE switches makes Ge switches an indispensable choice. The following describes the structure of a gigabit network

When the main performance of the LAN can not meet the new application requirements of the enterprise, we must consider to upgrade the network. Upgrade should be based on the needs of network applications, analysis of network upgrade to solve the problem, in particular, upgrade the switch hardware equipment, this articl

Many of us do not know much about wireless network devices. How does a wireless switch work? This article provides detailed answers to this question.
WLAN switching technology centrally controls access points and wireless switching functions, which is very similar to smart switching technology in the Wired World. This technology provides the structured blueprint and centralized troubleshooting capabilities
With the development of the access network technology, its related devices are also widely used in various fields, and there are also many problems, especially some problems such as ARP attacks, next we mainly analyze the solution to the access network switch problem. The mature telecom-level IP technology makes the integration of voice, data, video, mobile and o
Undeniably, the establishment of a local area network, security is essential. Let H3C's "fortress" to help you stop the virus attack!
Don't get me wrong, we're not talking about firewalls, but building H3C gigabit secure LANs: S5500-si and S5120 series switches. As a family member of Gigabit Network, in addition to the small and medium-sized office network to br
to configure our own DHCP server, Instead of having to specifically configure a single server to do the DHCP service. I'll take the Cisco switch (no other switch) as an example, and say the exact following: Suppose there are 400 hosts in a network, of which 255 are requested for allocation of IP, the range from 202.38.x.0~202.38.x.254, where 202.38.x.1 is used t
Nick McKeown, a professor of engineering at Stanford University, expects a new network processor to replace the ASIC currently used in routers and switches in the next decade; he said he has gone deep into the future of the Communication Processor: "and if you try to look at it with your eyes, it's like a network-based RISC processor."
McKeown assists in promoting a software-defined
layer of the Switch VLAN, not only can be manually configured, can also be automatically generated by the switch. After analyzing the packet, the switch automatically configures the VLAN and updates the members of the VLAN automatically. The third tier switches can work in a network environment where DHCP (Dynamic Hos

, You can switch the line by setting different gateways of the local Nic. It is often necessary to switch between two lines. It is troublesome to modify the gateway each time, so you can use netsh to switch the IP address.
Netsh is a self-contained command
, that is, the "clean" side of the firewall ).
The firewall is installed on the data path, which limits the network performance and scalability, because all data flows through the non-clean end and the clean end must flow through the firewall. The firewall uses filtering technology and other policies preset by network administrators to check each packet. The problem is that the processing structure most sui
vswitch performs logical operations on the filtering rules through the hardware "logical and non-Gate" to determine the filtering rules, without affecting the data forwarding rate.
Port-Based Access Control for 802.1X
To prevent unauthorized users from accessing the LAN and ensure network security, Port-based access control protocol 802.1X is widely used in both wired LAN and WLAN. For example, Asus's latest GigaX2024/2048 and other new generation
