???)Two-tier switches support physical layer and data link layer protocols, such as Ethernet switchesThe three-tier switch supports physical layer, data link layer and Network layer protocol, such as some switches that lead the way by function.
From the layered structure of iso/osi, the switch can be divided into two-layer sw
The switch power consumption index test and related problems in Lan. When a user encounters a problem in testing the Switch Power Consumption Index, others give some answers, but they are not very detailed, there are still many questions about Switch
Troubleshooting vswitch faults: for power supply faults and port faults, in the Internet era, you will often encounter troubleshooting vswitch faults. The following describes how to resolve vswitch faults, including how to solve power supply faults.
No matter how good the performance of a switch device is, there will be potential faults. Just like people, no matt
received a "get" request, the tester can easily prove whether the process is being executed at a certain level.
Next we will first explain the measurement indicators and other considerations of the power consumption and efficiency of LAN switches. The following describes how to measure the power consumption of LAN switches. What factors need to be considered when testing the
Nowadays, switching power supply has replaced linear regulated power supply and is active in the electronic power design field. People gradually realized that the switch power supply has changed the technical direction of the electronic design industry. In the
IntroductionTraditional routers have isolated networks, isolated broadcasts, routing and forwarding, and firewall operations in the network, and as the network continues to evolve, the load of routers is growing rapidly. One of the important reasons is that the VLAN (virtual local area network) technology is widely used in networks because of security and managem
status of the device, from the generator (or the Power Point bus segment) to search, using the node switch table and Node branch table, the device connected by the branch and closed switch connected equipment to form an electric island.
For the electric island coloring, according to the division of Electric Island, the electrical state of each electrical island
The previous day, a power failure caused a switch in the branch to fail to start.
Fault description: The day before yesterday, our branch colleagues called us and said they were connected to the organization. I went through the ping test and found that the gateway to the branch was successful, but I couldn't reach the branch server.
The preliminary judgment is whether the
the power industry. In this context, the power communication network is rapidly developing towards Digitalization, integration, and broadband.Previously, the communication networks of Power Enterprises designed several independent networks based on different specific services such as administrative communication, sche
When a power outage occurs in a medium-sized enterprise data center, what is a power switch? What is a medium-sized data center? The number of servers is more than 100, and the number of servers is less than 1000. Why do enterprises have to worry about power outages? The self-built IDC of medium-sized enterprises canno
group is controlled by an air switch, internet cafes can be divided into 4-6 groups or more groups.
Select the model of the power cord Based on the load of each trunk. In general, the main line uses copper core lines, the following branch lines can use aluminum core lines I suggest, it is best to all the lines of the Internet cafe Power System Using GB copper co
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-
Customer Profile
A power plant is a large-scale thermal power generation enterprise. As early as 1993, it established a 10 Gigabit network of computers covering the entire plant. This year, it was transformed into a Gigabit Ethernet network, and the core of the power plant a
technology. Cisco released the Fast-Start EnergyWise plan at the latest Cisco Live. This plan provides JouleX products to Cisco Catalyst 3 K and 4 K switches for free.
Joulex CEO and President Tom Noonan said: "Fast-Track free SKU allows Cisco customers to directly obtain the PoE device monitoring function attached to the switch. If they want to monitor servers, printers, replicas, PCs, and storage devices, they must be upgraded ."
At the same time,
The concept of management is very important to all walks of life. If an enterprise cannot effectively manage it, the cohesion of the Enterprise will be very weak and the development of the Enterprise will be severely hindered; if an army is not managed, it will become a sandbox with no fighting power. If a network cannot be effectively managed, the use of such network
gossip, he will be overwhelmed by small groups sooner or later, but we have mastered the reward system, have you read the currency war? "As long as I know the currency issuance right, I don't care who makes the law," roschard said)
I suddenly found out that this network manager is still a banker: "you mean dkp is currency, reward system is the means to control the value of currency, and participation in dkp is the consumption
There are many things worth learning about Ethernet switches. Here we mainly introduce Ethernet switch configurations and network types. Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type switch, which has good scalabilit
The configuration of a vswitch has always been mysterious, not only for general users, but also for the vast majority of network administrators. It is also an important and basic indicator for measuring the level of network management. This is mainly due to two reasons: first, the switches configured by the vast majority of enterprises are non-Network-connected v
Managing the vswitch configuration file is still very important for users, but many users still do not pay much attention to it. This is very dangerous and their networks will also have security risks. The configuration file is the core of Cisco network devices. The configuration file is like the Registry file of the operating system. If the registry is damaged or the configuration is inaccurate, the operating system cannot be started or run stably.

Ethernet switches are still commonly used. So I have studied Ethernet switch configurations and supported network types. I would like to share them with you here and hope they will be useful to you. Rack-mounted switch, fixed configuration with/without expansion slot) rack-mounted switch is a slot type
