Internet access establishes a communication link between the client and the access server of the carrier through PPP. At present, broadband access is becoming a trend to replace dial-up Internet access. In today's ever-changing broadband access technology, PPP has also developed new applications. The typical application is in the ADSL asymmetric data user Loop, asyuncrical Digital Subscriber Loop) access m

IP addresses are addressing mechanisms at the TCP/IP network layer, Mac is the addressing mechanism of the 802.3/Ethernet link layer, They are different levels of things, not a side-by-side relationship. Think about whether the data is sent to the network cable or it turns into an electrical pulse. TCP/IP is not defined by the physical layer, the IP packet must be processed over Ethernet before it becomes

entities, which is responsible for functions such as traffic and error control, so it should belong to the Data Link layer protocol.Under the PPP protocol, the physical layer, such as Ethernet and serial port, is above the network layer such as IP protocol. Here, for the lower level, we only discuss the situation of the serial port, for the upper level, we only discuss the TCP/IP situation. When sent, TCP/

In today's ever-changing broadband access technology, PPP has also developed new applications.

). Throughout the connection process, CHAP repeatedly sends the challenge password to the client from time to prevent the remote client impersonation attack by the 3rd party. 6. PPP protocol is currently one of the most widely used protocols on the Wide Area Network. It has the advantages of simplicity, user verification capability, and IP Address allocation. Domestic dial-up Internet access establishes a communication link between the client and the

Network in two different places. Each router will unencapsulate the HDLC data packets and forward them to the LAN or discard them. HDLC's correction of errors is similar to Ethernet. The Cisco version of HDLCA is more private, and they specifically add a protocol type domain. Therefore, Cisco HDLC can only work on Cisco devices. HDLC is actually a default setting on all Cisco serial interfaces. If you create a showrunning-config on a Cisco router, yo

PPP protocol is one of the most widely used protocols in the WAN, which has the advantages of simple, user-authentication capability, and can solve IP assignment. A home dial-up is a communication link between the client and the operator's access server via PPP. At present, broadband access is becoming the trend to replace dial-up Internet, in the rapid development of broadband access technology today,

Problem Disconnect PPP, do not report no CARRIER Phenomenon 1 When the customer negotiates the authentication mode in LCP phase, the module requests PAP, and after being rejected by the MCU, the module sends the terminating frame. However, in the PPP process, no carrier is seen to escalate, and the module does exit the PPP
