The backboard bandwidth is the maximum amount of data that can be transferred between the vswitch interface processor or interface card and the data bus. The higher the bandwidth of the backboard of A vswitch, the stronger the ability to process data, but the design cost will also rise.However, how can we check whether the bandwidth of A vswitch is sufficient? Obviously, the estimation method
(the computer is turned off) the port status of the computer and the switch is still up, but the MAC address under query for this port is empty .Preliminary suspicion causes:Wake-on-lan (computer shutdown, network card is still working)Wake-on-lan, known as WOL,
Ask if there is any performance difference between iframe and ajax on the partial switchover page. if so, is there a big gap? Which one has better performance? It has always been the development of a simple business layer. if the problem is too small, please bear with the ThinkPHP framework. if there is such a page, cl

A tiered switch is a type of switch. According to the design, the switch can be stacked on top of the other. This switch is different from a rack switch and can be placed in a network c
Two-layer switch refers to only the second layer of OSI (data Link Layer) Exchange technology of the switch, the development of two-tier exchange technology is more mature, the two-tier switch is a data link layer equipment, can identify the data packet MAC address informati
The author office used a common two-layer switch, has been silent for us for several years, so far there has been no accident. However, recently, the author of the local area network computer room has a switch suddenly strange phenomenon; taking into account the particularity of the fault phenomenon, the author used a special method to exclude, now the specific troubleshooting process

Basic ISSUESThe FreeRTOS will perform a process switchover in the zone where the critical area is taskenter_critical () and the taskexit_critical () package. That is, the process switches when the interrupt is closed. we already know that even if the interrupt is off,
Three-tier switches and routers have routing capabilities.
But the main function of the three-tier switch is still data exchange, its routing function is usually relatively simple, because it is mainly faced with a simple LAN connection, routing path is far from the router
In the early 90, with the improvement of computer performance and the increase of traffic, traditional LAN has more and more exceeded its own load, switching Ethernet technology came into being, which greatly improved the performance of LAN. The two-tier switch plays a key role in the development of the switch technology, but with the maturity of the two-layer switch
Experts tell you what a layer-3 switch is. Now every household has their own computer and understands what a layer-3 switch is. At that time, the layer-3 switch was based on software and the forwarding speed was very slow, later, it was developed to implement layer-3 switchi

When configuring VI, the general user will display syntax highlighting, but switching to root user highlighting is always unsuccessful, what is the reason? (Redhat)originally for the general user, when we look at the command aliases we find VI = VIM [[emailprotected] ~]$ which VI alias vi= ' vim ' /usr/bin/vimfor Root, this alias is not defined by default. so V

Security switches-The new darling of the network, the gatekeeper of the network entrance, the ambition is to raise the broadsword to all unsafe factors.
The advent of the network era makes the security problem an urgent problem to be solved. The existence of viruses, hackers and various vulnerabilities makes security tasks difficult in the Internet age.
The switch occupies an important position in the ent
For a long time before the frame Sealing Failure of a switch occurs, our network is normal. You can force the super engine to set the Trunk of IEEE 802.1Q. After the network is stable, connect the jumper to the igabitEthernet 3/48 interface.

Large projects will inevitably lead to fierce competition. large manufacturers will use brand advantages, public relations, service commitments, and market reputation, so where is the share of smart switches in the market, is a smart switch really smart?

As the core "Hub" for data exchange and transmission in Lan, the running performance of vswitches directly affects the efficiency of network data transmission. Generally, common L2 switches are not prone to faults. However, a common L2 Switch in the training center has encountered an inexplicable fault recently, considering that the fault is a bit strange and easy to occur, it
The core switch adopts the distributed CrossBar and distributed switching architecture to solve the large-capacity switching problem. Currently, all switches support full duplex. The advantage of full duplex is low latency and high speed, the following is a description.
