Ethernet switch工作在是Layer 2(OSI的第二层),即基于Ethernet MAC地址进行交换 1.2工作原理 初始化过程:switch的地址表为空,此时switch不转发任何报文; 地址学习过程:switch根据接收的报文,记录报文的源mac地址以及对应的端口号,并记录到switch地址表中,同时广播该报文到其他的端口; 单播通信过程:如B(源端口2)向A...
According to the OSI or TCP/IP model, the Layer 2 switch works on the data link layer, while the Layer 3 switch works on the network layer. What’s the detailed difference between the Layer 2 and Layer 3 switch? Part I. What Is Layer 2/Layer 3 Ethernet Switch? Layer 2 switchworks ...
HUB、Switch、Router在OSI模型中分别是第几层设备,各层的名称是...第二层：数据链路层，主要设备：二层交换机、网桥。第三层：网络层，主要设备：路由器。后四层依次为：传输层、会话层、表示层、应用层。后四层主要是计算机软件控制。第一层：物理层（PhysicalLayer)，规定通信设备的机械的、电气的...
of Layer 2, and to handle Layer 3 IP packets, Layer 3 switching technology was born. The working principle of Layer 3 switching technology: Layer 3 switching works in the third layer of the OSI, that is, the network layer. It uses the packet header information of the IP packet in the...
Layer 2 switch A switch that works at Layer 2 (data link layer) of the OSI model and can identify MAC addresses in data frames. A Layer 2 switch is also known as an Ethernet switch. Layer 3 switch A switch that works at Layer 3 (network layer) of the OSI model and provides therou...
When trying to understand and select the right switch for your needs, you will need to know which layer it will operate on and what functionality is available for that layer. There are seven layers in the open system interconnection (OSI) model of netw
Layer 2 and Layer 3 switches handle data at different layers of the OSI model, and PoE, Stackable, and Smart switch have their specific use cases. How Does a Switch Work? A Vivid Explanation for You. As mentioned above, a switch is a device that connects multiple devices on a network ...
