The difference between managed and unmanaged switches

The difference between managed and unmanaged switches

1.The function is different:

The data of the managed switch is configured through Simple Network Management Protocol (SNMP), which is the most widely used network management protocol based on TCP/IP network. It can perform data address, port, protocol type, service, etc. Filtering, usually also has VLAN division.

The unmanaged switch lacks the network management function and does not directly process the data. Therefore, there are still quite large markets in some specific industries and fields, such as power industry, coal mining industry, transportation industry, etc.

2. Different working modes:

The managed switch product provides multiple network management methods based on the console control port, web-based page, and Telnet-enabled remote login network. Therefore, the network administrator can perform real-time monitoring of the working status and network running status of the switch in real time, and manage the working status and working mode of all switching ports globally.

The unmanaged switch belongs to the data link layer device and can identify the MAC address information in the data packet, then forward it according to the MAC address, and record the MAC address and the corresponding port in an internal address table.

3. The definition of the two is different:

The task of a managed switch is to keep all network resources in good condition. The managed switch product provides multiple network management methods based on the console control port, web-based pages, and Telnet remote login network.

Unmanaged switches are relative to managed switches. The data of the managed switch is configured through Simple Network Management Protocol (SNMP), which is the most widely used network management protocol based on TCP/IP network. It can perform data address, port, protocol type, service, etc. Filtering, usually also has VLAN division.

Extended information:

The network management switch has three major indicators: the backplane bandwidth of the switch determines the maximum upper limit of the connection bandwidth between each interface template and the switching engine; the switching capacity is the core indicator of the network management switch; the packet forwarding rate determines the size of the switch forwarding capability. .

Most of the mainstream switches in the market have the function of network management to ensure that all network resources are in good condition, so that the stability and security of the network are most effectively guaranteed.
