Cisco Switch Cluster Technology
For the connection between switches, there are two kinds of familiar ones: one is stacking, and the other is cascade. The method of cascading is more likely to cause bottlenecks between switches. Although the stacking technology can increase the backplane rate, it can eliminate the bottleneck problem of the connection between switches. However, it is limited by distance and the number of switches. It is also stricter.
Cisco's switch clustering technology can be seen as a combination of stacking and cascading technologies. This technology can logically combine switches distributed across different geographic areas for unified management. The specific implementation method is to select one Commander among the clusters, and the other switches are subordinated and managed by Commander. The Catalyst 3512XL, Catalyst 3524XL, and Catalyst 3508G XL models in the new Catalyst 3500 XL series can be Commander, and the Manager 2900 and 1900 Series can join the switch cluster, using Cisco's latest switch cluster technology to traditionalize The stacking technology has been upgraded to the next level. It is said that the 2900XL series can also be a Commander.
Designed for mid-sized businesses, the series delivers high performance and low cost while reducing complexity and ease of integration into existing networks. It allows network administrators to use standard web browsers. Manage geographically dispersed switches from anywhere on the network with a single IP address.
