1. Set the TCP/IP attribute of the NIC first: IP Address: 192.168.1.2 because the default IP address of the cat is 192.168.1.1, as long as it is in the same network segment as it) The subnet mask is 255.255.255.0. Add 192.168.1.1 as the new Gateway Set an available DNS! 2. Open the browser and enter http: // 192.168.1.1 in the address; username and password harbor) to enter the WEB configuration interface. 3.

We certainly don't know the MAC protocol. This Protocol defines the network address and is the foundation of our network. Now, we will give a brief analysis and introduction on this protocol, hoping to give you a deeper understanding of this Protocol. Meaning Media Access Control Meaning Media Access Control It defines how data packets are transmitted on the media. In a link that shares the same bandwidth, access to the connection media is "first served. Physical addressing is defined here, and

. Therefore, the main function of this layer is to provide the physical layer on the basis of the bit stream, through the error control, flow control method, the error of the physical line into a error-free data link, that is, providing a reliable way to transfer data through physical media.This layer is also typically divided into two sub-layers of media access control (MAC) and Logical Link Control (LLC).The main task of Mac sub-layer is to solve th

to a user's wireless network. Expansion:MAC (Media Access control) media involves the control layer, which belongs to the lower sublayer of the data link layer in the OSI model. It defines how data frames are transferred on the media, and access to the linked media is "first come first served" in the link that shares the same loan. Physical addressing is defined here, and the logical topology (the path through which the signal passes through the physical topology) is also defined here. Line con

reliable data transfer over a physical network link. Different data link layers define different network and protocol features, including physical addressing, network topology, error checking, frame sequences, and flow control. The data link layer is actually comprised of two separate parts, media access control (media access Control,mac) and the Logical Link Control layer (Logical link CONTROL,LLC). The data link layer is responsible for establishin

GPRS data transmission plane Compared with GSM, GPRS reflects the characteristics of group exchange and group transmission, that is, data and signaling are based on a unified transmission platform. As shown in the figure above, the Protocol structures below the transfer layer (LLC) are the same for data and messaging on Several Interfaces passed by data transmission. In GSM, data and signaling are only the same on the physical layer. GTPs: GPRS prot
