What is the difference between network management and non-network management switches?

Managed switches are more powerful than unmanaged switches. It typically provides Simple Network Management Protocol (SNMP) for monitoring connection status, STP, other advanced QOS-like features, and VLANs. These characteristics vary by vendor and mode. Network management switches are much more expensive than non-network management switches, and they are more time consuming than non-network management switches. The differences between the managed and unmanaged Ethernet switches are described in detail below.

First, non-managed switches

Disadvantages of unmanaged switches:

1. Non-network management industrial switches have limited functions and are suitable for small networks.

2, does not support ARP protection, ARP attack is not a virus and almost all anti-virus software is helpless; but it is better than a virus - because it can cause slow communication, network paralysis, and will cause information leakage.

3. The binding of mac address is not supported.

4. The vlan is not supported. When the end users connected to the non-network management switch are in the same broadcast domain, the broadcast storm will occur and cannot be protected and suppressed. Congestion, blocking, and flooding of the entire network cause the entire network to collapse.

5. Traffic-based control is not supported.

6. The reliability of data transmission is poor, and packet loss is serious.

7. Single assembly, can not be applied in large and medium-sized networks, and has great limitations on network upgrade and expansion.

8, management is inconvenient, the hardware failure rate is relatively large.

Advantages of unmanaged switches:

1, the price is cheap, save money.

2. The number of ports is dense.

3, the user is flexible.
 

Second, network management Ethernet switch

Advantages of managed Ethernet switches

1. The backplane has a large bandwidth and the data forwarding speed is faster.

2. Flexible networking, applying the access layer of large and medium-sized networks.

3. The ports provided are flexible. According to the application of the network, different interface formats such as SFP, GE, Fast Ethernet port, and Ethernet port are selected.

4. Supporting the division of vlan, users can divide the area for different applications and effectively control and manage the network. Progress has curbed the broadcast storm. 5. The data throughput (Throughput) of the network management switch is large, the packet loss rate (PacketLoss) is small, and the delay (Latency) is low.

6. Data flow control can be performed based on source, destination, and network segment.

7. Link aggregation allows the switch and the switch, as well as the switch and the server to be bound together through multiple Ethernet ports to implement load balancing.

8, with ARP protection, progress to reduce network ARP spoofing.

9. Binding with a MAC address.

10. Port mirroring can copy the traffic and status of one port to another port of the switch for supervision.

11, support for DHCP functions.

12. Access Control List It can control IP packets, such as limiting its traffic, access and providing QoS, and so on.

13, has a good security performance: the switch can perform MAC address filtering, MAC address locking, and can build a static MAC forwarding table.

14. Supports IEEE802.1Q and port-based VLANs. GVRP (GARP, VLAN Registration Protocol) and GMRP (GARP Multicast Registration Protocol) involved in IEEE 802.1Q VLAN are also widely supported.

15, with SNMP function, can better manage and control the network.

16, easy to expand, flexible application, can be managed by network management software, or remote access through its own access control. Increase the security and controllability of the network.

The unmanaged switch is simple to use, but it cannot be configured. The network management type has a web management page. You can log in to the web management page to configure the switch (allocate port vlan, set port rate, etc.).
