Now that the network is so popular, the demand for switches is becoming more and more important. There are so many models of switches on the market. We have analyzed how to distinguish switches according to different situations before, but when we browse the names, we will also find that many switches In the introduction, both the managed switch and the unmanaged switch are written. The literal meaning of the switch is clearly expressed. This time I will summarize what this "network management" does. Next, let's follow the editor of Feichang Technology to learn more about it!
1. Unmanaged Switches
First of all, let's talk about unmanaged switches. Unmanaged switches are also called fool-type switches. Simply put, they do not directly process data, just plug in the Internet cable.
The unmanaged switch belongs to the data link layer device. It can identify the MAC address information in the data packet, then forward it according to the MAC address, and record these MAC addresses and corresponding ports in an internal address table.
Its advantage is that it is easy to use, plug and play, can be used in a large number of series, suitable for use in places with high PC equipment density, and it is cheap to save money.
2. Network-managed switch
Network-managed switch means literally, a switch that can be managed by the network. There are three management methods, which can be managed through the serial port, through the Web, and through the network management software.
The data of the network management switch will be configured through the Simple Network Management Protocol (SNMP). The SNMP protocol is currently the most widely used network management protocol based on TCP/IP networks. It can perform data address, port, protocol type, service, etc. Filtering, usually also has a VLAN division function.
The task of the managed switch is to keep all network resources in good condition. The network management switch product provides a variety of network management methods based on the terminal control port (Console), based on the Web page, and supports Telnet to remotely log in to the network. Therefore, network administrators can perform local or remote real-time monitoring of the working status of the switch and network operation status, and manage the working status and working mode of all switching ports in a global view.
3. What are the advantages of managed switches?
1. Large backplane bandwidth and faster data forwarding;
2. There are many types of ports provided, and different interface forms such as SFP, GE, fast Ethernet, Ethernet, etc. can be selected according to the application of the network;
3. Support vlan division , Users can divide areas for different applications, effectively control and manage the network, and further suppress broadcast storms;
4. Large data throughput, low packet loss rate, and low latency;
5. Link aggregation allows switches and switches And the switch and the server are bound together through multiple Ethernet ports to achieve load balancing;
6. The data information flow can be controlled based on the source, destination, and network segment;
7. With the ARP protection function, it improves the reduction of network ARP spoofing;
8. MAC address binding;
9. Port mirroring function can copy the traffic and status of one port to another port of the switch for supervision;
10. Support DHCP function;
11. Access control list for it It can control IP data packets, such as restricting its traffic, access, and providing QoS, etc.;
12. It has good security performance, can perform MAC address filtering, MAC address locking, and can build a static MAC forwarding table;
13. It can support IEEE802.1Q and VLAN based on port technology. GVRP (GARP, VLAN Registration Protocol) and GMRP (GARP Multicast Registration Protocol) involved in IEEE802.1QVLAN are also widely supported;
14. With SNMP function, it can better manage and control the network;
15. Easy to expand, flexible application, it can be managed through network management software, and it can also be accessed remotely through its own access control, which increases the security and controllability of the network.
Well, the above content is about the advantages of Feichang Technology's network management switch compared with ordinary switches? A detailed introduction to this issue, I hope it can be helpful to everyone!
