technologyIn fact, POS technology uses SONET/SDH devices/frame structures to transmit IP services. It uses the SDH standard frame structure, and uses the point-to-point transmission encapsulation technology to encapsulate the IP service and then transmit it on the optical fiber or transmission system. The POS standard encapsulation protocols mainly include PPP/HDLC, laps, and green code encapsulation protocols.2.1. PPP/

Www.2cto.com (File Transfer Protocol) File Transfer Protocol is a standard Protocol and the easiest way to exchange files between computers and networks. FTP is also an application protocol standard that applies the TCP/IP protocol, just like the HTTP and SMTP of the e-mail that delivers the display file. FTP is usually used to upload a webpage from the Creator to the server for use, whi

(NetBIOS Enhanced UserInterface) Network Basic Input/Output System extended user interface The NetBEUI protocol was proposed by IBM in 1985. NetBEUI is mainly designed For a LAN of 20 to 200 workstations. It is used For NetBEUI, LanMan, Windows For WorkgroUPS, and Windows NT networks. NetBEUI is a compact and fast Protocol. However, because NetBEUI does not have the routing capability, it cannot route from one LAN to another, and can no longer adapt to a large network. To route to another Lan,

Global debugging When configuring a Cisco router, the bounds of global and interface commands are obvious. In this case, we use "global" to identify those commands that cannot be used for interface debugging or for specific transport media types and protocol debugging. For example, in the 2500 series router, you can use the Debug command to analyze the Cisco Discovery Protocol (Cisco Discovery PROTOCOL,CDP). We telnet remotely to the router by remote. By default, the output of the debug command

Wan protocol encapsulation Target: Measure the test taker's knowledge about the encapsulation types and methods of Wan protocols. Tutorial principle: Common Wan leased line technologies include ddnleased line, PSTN/ISDN leased line, Frame Relay leased line, and X.25 leased line. The data link layer provides various leased line protocols, including PPP, HDLC, X.25, Frame-relay, and ATM. Experiment topology: 650) this. width = 650; "src =" http://www.bk

The usual encapsulation technology is the encapsulation of Ethernet, PPP and HDLC. Ethernet is often used for the connection between local area networks, and the latter two are commonly used for WAN encapsulation.The Ethernet (Ethernet) frame format Ethernetⅱ is one of the most common Ethernet frame formats and is also the de facto standard for today's Ethernet.The main feature of Ethernetⅱ is the protocol used by the type domain to identify packets e

It Allow both parties to negotiate options such as IP address and maximum

This article describes in detail how to configure Cisco routers in terms of global debugging, interface debugging, and Protocol debugging. I believe this article will help you. Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debuggin

For example, router OSPF 2.· Define the subnets involved in OSPF. In configuration mode, enter the network IP subnet number wildcard area number. Vro only supports subnet information exchange in the same region, but does not exchange route information between regions.· Specify the network type. In configuration mode, enter the

Interfaces in the LAN encapsulate the Ethernet type. In the WAN, the interface is generally a serial port encapsulation of ppp hdlc snip Frame-Realy ARP is used for Ethernet, And it communicates with MAC addresses. If both sides of the serial port are PPP or HDLC, the two layers will be connected, and frame relay uses DLCI. (N.1) s0 \ 0 ports of RI \ R2 are blocked by PPP R1s0 \ 0 ip address 192.168.1.1 2

to ensure the proper protocol is used, the router must be configured with the appropriate layer 2nd encapsulation.The choice of the protocol needs to be determined based on the WAN technology and communication equipment used. The router encapsulates the packet in two-layer frame format and then transmits it to the WAN link. Although there are several different WAN packages, most have the same principle. This is because most WAN packages evolve from high-level Data link Control (
