managed switch vs unmanaged switch

Grasp the main performance indicators of Gigabit switch is the key, and judge the performance of the switch, you need to start from the following factors: Forwarding Technology Store-and-forward technology requires the switch to decide how to forward after receiving all packets, and the gigabit switch with this techn

components may not be hot-swappable.Heat Exchange Component Management Card, switching structure, interface module, power supply, cooling system)For management engines and exchange array modules that provide key services, they require not only redundancy, but also "automatic switching" to ensure the integrity of redundancy, when such a part fails, the redundant part can take over the work to continue the operation of the device. This ensures the reliability of the device. Support Port Link aggr

capability of the entire product is 16.8 Gbps. The process of the chip is 0.13um. 3) The BCM5324 chip for the smart market is the world's first switch chip integrated with 24-port MB of PHY, with a higher integration level and better performance. BCM5324 supports all the features required by L2 managed switches. The solution aims to meet and exceed the needs of small and medium-sized enterprise customers f

different, and so on. As these problems are solved, the foundation of your products will be stronger. When designing a cisco Gigabit Switch, device manufacturers usually need different settings to meet customer needs. These requirements generally include the following:◆ Stacks can be used for full scalability;◆ Elastic backbone scalability can be obtained through the frame structure;◆ It can be integrated with server devices to achieve integration of

communication is performed for a variety of multimedia applications. IEEE80D/STP When the IEEE80D Spanning Tree Protocol SpanningTreeProtocol detects a loop on the network, it will automatically disconnect the loop. When there are multiple connections between vswitches, only one of the most important connections will be started, and other connections will be blocked, and these connections will be changed to standby connections. When a primary connection fails, the Spanning Tree Protocol automat

Because the portable computer is easy to carry, the configuration switch is usually done with a notebook computer, there is no notebook in the case, you can also use the desktop, but moving up some trouble. The local configuration of the switch is communicated by means of a direct connection between the computer and the Console port of the switch, and its connect

1. The MAC address of the two layer switch itself is optional. The two layer switch can be divided into "network management" and "non-managed" two types, for "managed" switch, we can configure its parameters, and "non-managed"

Flood Attack of the network virus? At this time, we think this phenomenon is more like a loop in the network. When we arrived at that department, we found that three non-managed switches were all bundled together. However, two of them were connected to the access switch through the two network cables, which resulted in a network loop. Apparently, the construction staff was not clear about the network topol

After using the Console port to set IP address information for the switch and enable the HTTP service, you can access the switch through a Web browser that supports JAVA, you can modify the parameters of a vswitch through a Web browser and manage the vswitch. In fact, you can modify and set many important parameters of a vswitch on the Web interface, and view the running status of the vswitch in real time.

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 required to extend WLAN beyond the Department

Tags: Zhao Guangsheng Vmware You can use the vsphere distributed switch to set network connections so that a vswitch can span multiple servers. One end of the vswitch is connected to the port group of the virtual machine, and the other end is connected to the uplink of the physical Ethernet adapter on the server. The Virtual Machine is connected to the physical environment through the physical Ethernet adapter connected to the uplink of the virtual

switch to root identity, if a user accidentally leaked the root password, it is not very insecure system? No mistake, in order to improve this problem, yielded the sudo command. Usesudo executes a root command that can be executed, but requires a password that is not the root password but the user's own password. By default only the root user can use the sudo command, and the normal user wants to use sudo, which requires root pre-set, i.e., usingVisu

the transfer path, which can be used only once or stored for future use. Then, data packets are quickly sent through a virtual circuit bypass the router. The emergence of layer-3 switching technology solves the problem that the subnet must be managed by routers after the network segments are divided in the LAN, and solves the network bottleneck caused by the low speed and complexity of traditional routers. Of course, the layer-3 switching technology

There are many things worth learning about layer-3 switches. Here we mainly introduce the technical principles of layer-3 switches. In short, layer-3 switching technology is layer-2 switching technology + layer-3 forwarding technology. It solves the network bottleneck caused by low speed and complexity of traditional routers. What is layer-3 switching? Layer-3 switching is also called multi-layer switching technology or IP address switching technology. As we all know, the traditional exchange te

If there is no port aggregation on the vswitch. Your two computers are connected with two network cables. It turns into a ring, which affects both the switch and the connected computer. Therefore, the port aggregation function is crucial for Internet cafe switches. This section briefly describes information about the port aggregation function of a managed switch

Comparison with L2 Switching The distributed L3 switch supports popular routing protocols and organically combines the advantages of L2 switches with vrouters. l3 switches can control IP addresses, making it easier to build large-scale local area networks. 3. Differences from centralized layer-3 core exchange Distributed layer-3, which can be
