Explain the application of switch cluster technology in Enterprise Networks (1)

Network management can ensure the normal operation of enterprise networks. network management is required in larger enterprise networks. Generally, network management is implemented through software. Many vswitches also have certain network management functions. Many enterprises also have network management personnel. Because the reliability of the device is relatively high, the probability of failure is relatively small, but the network administrator is still very busy, especially when updating the device or upgrading. Some new technologies have emerged to Facilitate network management. Switch clusters are one of them, and they are very suitable for small and medium-sized enterprise networks.

I. Question proposal　

Network management is a highly repetitive task that takes a long time. Network administrators generally need to configure, monitor, and update computer LAN switches at the same time. This intensive labor is not good for enterprises to quickly develop or update network configurations based on changing needs.

Fortunately, this approach changes the way network administrators configure and update each switch, because this time-consuming and laborious method hinders the development of enterprise networks, this has attracted the attention of the industry, so some new technologies have changed. For example, the first generation of stacked switches that emerged in 1996 allows network administrators to manage multiple switches as a logical group on the console and solve the scalability of the system. Of course, the first generation of stacked switches also has some shortcomings. First, the management of multiple switches connected to a distribution cabinet is very limited. Second, in order to obtain the advantages of stack management, the user must upgrade the existing switch because the stacked switch requires dedicated ports and cables. Finally, most stacked switches lack common and easy-to-use management interfaces.

To expand the network management capability of Switch stack, Cisco System Corporation has introduced the Switch cluster Switch tertering innovative technology. This technology enhances the management capabilities of large and medium-sized enterprise networks. without adding any resources or changing the lines with switches, it can span multiple distribution cabinets and multiple LAN transmission media, expand and update the enterprise network. Using Cisco's switch cluster technology can eliminate the geographic boundaries of distribution cabinets. This technology adds Web-based management software, so you do not need to learn complex management commands, but also can manage different types of networks and devices. Using this technology is compatible with existing Cisco workgroup-level switches, because cluster functions are implemented through software and no dedicated hardware ports are required.
