Talking about Ethernet Switch protocol

Ethernet switch is a kind of network device which is based on MAC address recognition and can complete the encapsulation and forwarding data packet function. The switch can "learn" the MAC address and store it in an internal address table, by establishing a temporary exchange path between the originator of the data frame and the target receiver, so that the data frame is reached at the destination directly from the source address. 1. The switch maps the address to the switch port based on the source MAC address received in the data frame and writes it to the MAC address table. 2. The switch compares the destination MAC address in the data frame with the established MAC Address table to determine ...

The concept and working principle of ARP protocol

We know that when we enter the URL in the browser, the DNS server will automatically resolve it to the IP address, the browser is actually looking for the IP address rather than the URL. So how does an IP address convert to a second-level physical address (that is, a MAC address)? In the LAN, this is done through the ARP protocol. ARP protocol is of great significance to network security. ARP spoofing is achieved by spoofing IP address and MAC address, which can cause a large amount of ARP traffic in the network to block the network. So the network management should understand the ARP protocol deeply. First, what is the ARP association ...
