How does a switch work?
The working principle of the switch includes: 1. Data frame reception and analysis; 2. Forwarding table update; 3. Data frame forwarding; 4. Flood processing; 5. Connection maintenance.

How does a switch work?The working principle of the switch is to achieve this function by learning and forwarding data frames. When the switch receives a data frame, it parses the source MAC address in the data frame, associates the address with the corresponding interface, and stores this information in the internal forwarding table. The forwarding table is a very important data structure in the switch. It records the correspondence between MAC addresses and interfaces. This forwarding table is established through a learning process, that is, when the switch receives a data frame, it associates the source MAC address in the data frame with the interface that received the data frame.
How to implement switch WIFI configurationA relatively simple WiFi configuration I did recently was responsible for a firewall, a core switch, and a PoE switch. Neither AC nor AP are our responsibility. Let’s talk about the configuration of the firewall first: I won’t talk about the conventional deployment. G1/0/0 of the firewall is connected to the operator, set to the untrust zone, and configure the public IP address provided by the operator, 1.1.1.1G1/0/ 1 Connect to the core switch and set it to the trust zone. Configure the interconnection address security policy with the core switch: rulenametrustTOuntrustsource-zonetrustdestination-zoneuntrustsource-addres
What is a switchA switch is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The switch is only used to distribute network data. It can connect many hosts, each of which has its own external IP. The switch works at the relay layer, addressing based on MAC address, and cannot provide this function.
How does a switch work?The working principle of the switch is based on the second layer of the OSI reference model, the data link layer. A switch is a network device based on a learning process that enables communication between different devices in the network by parsing and forwarding data frames. The switch can continuously improve the contents of its internal forwarding table, improve the efficiency and reliability of data exchange, and ensure the stability and security of the connection. Switches are widely used in enterprise networks, data centers, campus networks and other scenarios to provide stable and efficient connection services for various applications.
