How to choose non-network management Ethernet switch and network management Ethernet switch

Network managed switches are more powerful than non-network managed switches. It typically provides simple Network Management protocol (SNMP) for monitoring connection status, STP, other qOs-like advanced performance, and VLAN. These characteristics vary from vendor to vendor and model to model. Nm-type switches are much more expensive than non-NM-TYPE switches, and their configuration takes more time than non-NM-TYPE switches. Plug-in operations are usually performed. The following details describe the differences between network managed and non-managed Ethernet switches.


Disadvantages of non-network managed switches:
1. Non-network management switch has limited functions and is suitable for small network.
2, do not support ARP protection, ARP attack is not a virus, so almost all anti-virus software can do nothing about it; But it is more virus-like because it can slow down communications and bring down networks, or leak information.
3. MAC address binding is not supported.
4. Vlan partition is not supported. If the end users connected on the non-network management switch are in the same broadcast domain, broadcast storms will break out and they cannot be protected and suppressed. Make whole network appear jam, block, flood, cause whole network to break down.
5. Traffic-based control is not supported.
6, the reliability of data transmission is poor, the phenomenon of packet loss is serious.
7. Single assembly, which cannot be applied in large and medium-sized networks, has great limitations on network upgrading and expansion.
8. Inconvenient management and large hardware failure rate.


Advantages of non-network managed switches:
1. It is cheap and saves money.
2. Dense number of ports.
3. Flexible usage.


Network management Ethernet switch advantages:
1. Large backplane bandwidth and faster data forwarding speed.
2. Flexible networking and access layer of large and medium-sized networks.
3. Flexible ports are provided, and different interface forms such as SFP, GE, fast Ethernet port and Ethernet port can be selected according to network applications.
4, support vLAN division, users can be based on different applications for regional division, effective control and management of the network. Progress damped the broadcast storm.
5. The data Throughput and Latency of the network management switch are large, while the PacketLoss rate is small and the Latency is low.
6. Can control the data flow based on the source, purpose and network segment.
7. Link aggregation enables the switch to be bound together with the switch and between the switch and the server through multiple Ethernet ports to achieve load balancing.
8. With ARP protection function, improve and reduce NETWORK ARP spoofing.
9. Binding with MAC address.
10. Port mirroring can copy traffic and state of one port to another port of the switch for monitoring.
11. Support DHCP functions.
Access Control List it can control IP packets, such as restricting their traffic, access, providing QoS and so on.
13, with good security performance: switch can be MAC address filtering, MAC address locking, and can build a static MAC to publish.
14. Able to support IEEE802.1Q and VLAN based on port technology. The GVRP (GARP, VLAN registration protocol) and GMRP (GARP Multicast registration Protocol) involved in IEEE802.1QVLAN are also widely supported.
15. With SNMP function, it can better manage and control the network.
16, easy to extend, flexible application, can be managed through the network management software, but also through its own access control to its remote access. Increase network security and controllability.


Disadvantages of network managed Ethernet switches:
1. Slightly more expensive than non-network management switches.
2. Compared with the non-network management switch, the operation is more complicated and requires configuration.
