the system prompts you to change the configuration to the baud rate of the Super Terminal: Restore the terminal's speed to 9600 bps. Press ENTER key when ready. After the modification, remember to perform the disconnection and connection operations on the Super Terminal to make the new attributes take effect. Then, the vro software starts to start. Use the show ver command to view the corresponding version information. Note the following when connecting with CISCO: 2. Differences in the default

, ISDN, and FR:PPP is a layer-2 protocol that solves point-to-point communication;CDP is on the top of Layer 2 and can be supported by NCP;The basic functions of HDLC are similar to those of PPP, but many things (such as authentication) are missing );Generally, PPP is encapsulated on the serial port, and logical interfaces (such as PPPoE) must be enabled on the Ethernet port );The default Encapsulation Format of Cisco is

The WAN protocol is relative to the LAN protocol, and the Internet can be identified as a wide area network. Then the relevant agreement is well understood. is inseparable from the OSI model. Here are a few typical protocols. To everyone as a reference. The WAN Protocol is a three-tier operation at the bottom of the OSI Reference Model, which defines communication on different WAN media. Mainly used for wide area network communication protocols, such as: Advanced Data Link Control Protocol, P

The two PPP authentication protocols (PAP and CHAP) for vroppp setting networking have just completed a test of Dual-router plug-in to the serial port module today, it is used to gain a deeper understanding of the differences between the two PPP authentication protocols PAP and CHAP. 1. First, build a network environment. There are two routers in total, plug in the serial port module respectively, and connect them using s0/0. 2. Configure an IP address, 192.168.1.1 and 192.168.1.2. Enable these

The ilogger interface in the SDK provides the general record function for the aee layer. There are three main implementations. The application author creates an ilogger instance by using the next classid: -Aeeclsid_logger_file: Send a log entry to the file; -Aeeclsid_logger_serial sends log entries to the serial port; -Aeeclsid_logger_win sends a log entry to the brew simulator output window. Both file implementation and serial record implementation output data to their respective output media i

Data Communication System control procedure ". this is a character-oriented standard that uses 10 control characters to establish, remove, and exchange links. these characters are also used to send and receive frames and restore errors. multiple link control and data transmission modes can be formed through the use of ISO1155, ISO1177, ISO2626, ISO2629 and other standards.2.2.2ISO3309 -- 1984: "HDLC Frame Structure ". ISO4335--1984: known as "

To master a protocol, we need to understand it based on it. Here we will analyze the content of the PPP protocol. First, let's take a look at the overview of the PPP protocol. Currently, most analog dial-up connections use PPP as the data link protocol, which has the following features: Error Detection Automatically negotiate network layer addresses CHAP or PAP Authentication Data Compression Meets ISO standards PPP and the serial line Internet Protocol SLIP) are often confusing. SLIP only suppo

) WAN technology overview operations are mainly concentrated at Layer 1, 2, and 3. Leased Line 2. The CN23 layer (ipsec) WAN Access Method is wireless, traditional wired ADSL, coaxial cable (TV signal conversion network digital), and Ethernet Access VPN: is the connection advantage between multiple private networks on the public network: low cost, good scalability, and compatibility with broadband technology connections in a variety of ways: IPsec, GRE, mpls vpn, l2VPN $ ########################

Read a table before introduction! What is the relationship between the L2 link and the OSPF network type?In fact, the relationship between the two networks can be larger. The OSPF network type should be selected based on the type of the L2 link, and the two applications match, that is, when the OSPF network type supports multicast, if the L2 link does not support multicast, problems may occur. For example, when the two routers use a PPP or HDLC link,
