Switches can be divided into network management switches and non-network management switches , rather than network management switches, also known as fool-type switches, without any settings, plug in the Internet cable. So what is an unmanaged switch? What are the differences between non-network management and network management switches? The following decoration home decoration network Xiaobian will give you detailed answers, I hope to help everyone.
What is an unmanaged switch?
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. However, the unmanaged switch does not directly process the data.
The working principle of the unmanaged switch:
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.
When the switch receives a packet from a port , it first reads the source MAC address in the packet header, so that it knows which port the source MAC address machine is connected to; and then reads the destination MAC address in the packet header. And find the corresponding port in the address table; if there is a port corresponding to the destination MAC address in the table, copy the data packet directly to this port; if the corresponding port is not found in the table, the data packet is broadcast to all On the port , when the destination machine responds to the source machine, the switch can learn which port the destination MAC address corresponds to, and it is no longer necessary to broadcast all the ports when the data is transmitted next time.
The difference between non-network management and network management switch:
The task of the managed switch is to keep all network resources in good condition. The managed switch product provides multiple network management methods based on the console console, web-based pages, and Telnet 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.
Unmanaged switches are those that support specialized "blade" servers with application capabilities , including protocol sessions, remote mirroring, tape emulation, and intranet file and data sharing. From an architecture with additional processing power for each port and a high level of bandwidth between blade servers, to a relatively simple server with dedicated processors, memory and input and output functions for communication between ports Architecture, intelligent switching has many different architectures.
The above is what Xiaobian brought to you. What is an unmanaged switch? The difference between non-network management and network management switches, I believe that everyone has a basic understanding of non-network management switches after reading this article, if you want to know more about decoration consultation, please click to enter the decoration knowledge channel .
