The connection sequence of RJ-45 line in common B standard is orange white, orange, green white, blue, blue white, green, brown white and brown. When connecting different equipment, use standard a. the connection sequence is green white, green, orange white, blue, blue white, orange, brown white and brown. Generally, the pressing method of b-mark is commonly used. If you want to make a cross line, one side is a standard, and the other side is b standard.

Working in the data link layer, the switch has a high bandwidth back bus and internal exchange matrix. All ports of the switch are connected to the back bus. After the control circuit receives the data packet, the processing port will look up the address reference table in memory to determine which port the NIC (network card) of destination MAC (hardware address of network card) is attached to. The data packet is quickly transmitted to the destination port through the internal exchange matrix. If the destination MAC does not exist, it will be broadcast to all terminals After the receiving port responds, the switch will "learn" the new address and add it to the internal MAC address table. The switch can also "segment" the network. By comparing the MAC address table, the switch only allows the necessary network traffic through the switch. Through the filter and forward of switch, the conflict domain can be effectively reduced, but it can not divide network layer broadcast, that is, broadcast domain. The switch can transmit data between multiple port pairs at the same time. Each port can be regarded as an independent network segment, and the network equipment connected to it can enjoy all the bandwidth without competing with other devices. When node a sends data to node D, node B can send data to node C at the same time, and these two transmissions enjoy the full bandwidth of the network and have their own virtual connections. If a 10Mbps Ethernet switch is used here, the total flow flux of the switch is equal to 2 × 10Mbps = 20MBps, and the total flow flux of a hub will not exceed 10Mbps when using 10Mbps shared hub. In a word, switch is a kind of network equipment based on MAC address recognition, which can encapsulate and forward data frames. The switch can "learn" the MAC address and store it in the internal address table. By establishing a temporary exchange path between the originator and the target receiver of the data frame, the data frame can reach the destination address directly from the source address.
