Explanation of mainstream enterprise-level three-layer switches in the market

Layer-3 switches are quite common, So I studied the mainstream enterprise-level layer-3 switches in the market and shared them with you here. I hope they will be useful to you. In recent years, the popularity of networks and the development of enterprises have overwhelmed the traditional exchange system, and the network environment of enterprises has been restricted. How to do a good job in enterprise network security protection measures, effective protection of enterprise information against viruses and malicious attacks has become the focus of attention. The emergence of layer-3 switches meets the urgent needs of modern enterprises.

For small enterprises, the network size does not exceed 200 nodes, so as long as a high-performance L2 Switch is connected behind the router to meet the requirements. For medium and large enterprise network structures with more than 200 nodes, L2 access switches are obviously unable to adapt to the formation of the network. l3 switches are the first choice.

The applications of layer-3 switches of different grades are also different. High-end Layer-3 switches are generally used in large-scale Local Area Networks, usually in the chassis and deployed on the core layer or aggregation layer, with extremely high switching board bandwidth and data throughput. The middle-end and low-end three-layer switches for the general commercial market are generally Standard 19 inch box switches. The middle-end all-gigabit layer-3 switch is suitable for medium and large network construction. It has at least 48 Gbit/s of Backboard bandwidth and can provide 10/100/Mbit/s self-fit full Gigabit switching ports and gigabit copper/fiber expansion slots. As a low-end general Gigabit Switch with 8-15 Gbps bandwidth, it can only provide 10/100 M Adaptive Fast Ethernet Switching ports and M or M copper/fiber expansion slots, suitable for small and medium-sized enterprises with low network performance requirements.

As a layer-3 switch with the routing function, it is much more expensive than a common switch, and the full-gigabit layer-3 switch at the end of a single platform is usually tens of thousands of yuan. Such a high cost also makes it difficult for most SMEs to accept the core Gigabit L3 solution. Considering the limited cost investment and network construction needs of many small and medium-sized enterprises with rapid development in the market, we recommend several million-level m layer-3 switches as a transitional solution for users to purchase.

DES-3326 is a 10/100 M Smart three-layer switch that can manage network and support Gigabit network, is a layer-3 Switch of line rate, provides 24 10/100 BASE-TX ports and 1 expansion slot, and 2 optional Gigabit Ethernet ports. The DES-3326 switch integrates Layer 2 line rate switching, Layer 3 IP routing, and QoS, and supports SNMP standard network management system for configuration, monitoring and management.

DES-3326 switch front-panel slot can be inserted with 2 Gbit/s modules, different modules can support 1000BASE-SX, 1000BASE-T standard. All modules support traffic control and full duplex to process large amounts of data. The priority queue and QoS mechanisms are supported. The priority queue function queues important data based on the importance of data exchange. The vswitch has the port aggregation function. It can aggregate up to eight 10/100 Mbps ports into one port, and the aggregated port has very powerful performance, this function is mainly used by users who require high-bandwidth ports and do not want to invest too much money. The main application of this function is VLAN division, which requires aggregation links, however, aggregation links have very high bandwidth requirements. Through the port aggregation function, a high-bandwidth port can be provided.

DES-3326 supports SNMP management and RMON monitoring, and port mirroring, through which, the administrator can manage and configure the vswitch and monitor the network connected to the vswitch. The DES-3326 switch also provides the traffic control function, supports VLAN division, and provides redundant power interface.

Comments: although for layer-3 Switch DES-3326 performance in general, support expansion slot is relatively small, but the low price is also in exchange for good cost effectiveness. DES-3326 switches are suitable for medium and small network core layer and large campus network convergence, providing Gigabit Ethernet modules can be connected to high-speed backbone network, to effectively alleviate network bottlenecks.
