Packet Tracer 5.0完整版带教程
Users of Packet Tracer 3.2 and 4.0 will note a variety of new features in Packet Tracer 5.0.Protocol Improvements
[url=http://www.certbible.org/cisco-packet-tracer-50-beta4]Packet Tracer 5.0[/url]modelsprotocols not included in earlier versions. These protocols includemodels of IPv6 Routing, IPv6 and IPv4 Dual Stack, IPv6 ND, IPv6 RoutingProtocols, DHCPv6, NATv6, Multi-Area OSPF, Redistribution, RSTP, SSH,Multilayer Switching, and EtherChannel. Also, a model of the CiscoCatalyst 3560-24PS Multilayer Switch has been added.
Extendable Architecture
[url=http://www.certbible.org/packet-tracer-50-full-version/]Packet Tracer[/url]is designed in a modular fashion for future expansionand the Packet Tracer team is interested in learning what new featureswould be most useful to the community.
GUI Improvements
[url=http://www.ccna.cc/]Packet Tracer 5.0[/url] retains thelogical topology as the primary workspace but adds additional physicalrepresentations of devices, Realtime and Simulation modes, and a widevariety of views and windows. The GUI supports multiple languages sothe application may be locally translated. New features included inPacket Tracer 5.0 are the following: Multiuser, ACL Filters, userprofile, improved print functuality, the ability to toggle toolbars inthe main interface, Desktop tab for the Server including IPConfiguration and Command Prompt dialogs, and various Activity Wizardimprovements including additional locking items, the ability toimport/export activity instructions, assign point values and componentcategories to assessment items, lock the user profile, toggle theDynamic Percentage Feedback, and the ability to test an activitywithout restarting from beginning.
Representation and Visualization Tools
An Event List, a form of global network sniffer, is included inPacket Tracer 5.0. This allows the display of the majority of simulatedPDUs as events. For detailed protocol analysis, these events may beplayed in a continuous animation mode, forward, backward or in astepped through process. Powerful OSI Layer view and PDU view, and moresophisticated custom PDUs, are also supported.
Annotation and Authoring Capabilities
Packet Tracer 5.0 improves upon the Activity Wizard of versions 3.2and 4.0. It also includes templates, or “design patterns,” for fourdifferent types of problem-solving activities: concept builders(network modeling problems), skill builders (pre-lab and post-labimplementation and practice activities), design problems, andtroubleshooting problems.
Uses for Packet Tracer 5.0
——————————————————————————–
For Students
Welcome to the world of computer networking. Packet Tracer 5.0 canbe a fun, take-home, flexible piece of software to help with your CCNAstudies, allowing you to experiment with network behavior and ask “whatif” questions. We hope that Packet Tracer 5.0 will be useful to youwhatever your goals are in networking, be they further education,certification, employment, or personal fulfillment.

The term “packet tracing” describes an animatedmovie mode where the learner can step through simulated networkingevents, one at a time, to investigate the microgenesis of complexnetworking phenomena normally occurring at rates in the thousands andmillions of events per second.
A typical instructional event might begin with an instructor posinga networking problem to the student. Students can use Packet Tracer todrag and drop networking devices (nodes) such as routers, switches, andworkstations into logical topology space (the Logical Workspace). Theycan then specify the types of interconnections between these devices(links) and configure the devices they created. Once they have designedand configured a network of nodes and links, they can then launchsample data packets into the network, either in real time, or in auser-controlled simulation mode. The packets are displayed graphically.The student can step the packet through the network, examining theprocessing decisions made by networking devices as they switch androute the packet to its destination. The networks, packet scenarios,and resulting animations can be annotated, saved, and shared. Manyimportant networking domain knowledge representations are available forthe student to pursue various modes of inquiry. Of particular interestto instructors is the Activity Wizard, which allows the authoring ofanswer networks to which students can compare their progress.
Packet Tracer 5.0 is based on three learning principles: learning isactive, learning is social, and learning is contextual. Hence, it ismeant to facilitate the creation of engaging, collaborative, andlocalized instructional materials. Packet Tracer may be used in avariety of ways:
Group work
Homework
Formative assessment
Hands-on lab reinforcement
Lecture demonstrations
Modeling and visualization of networking device algorithms and networking protocols
Case studies
Competitions
Problem-solving activities in concept-building, skill-building, design, and troubleshooting
Four problem types are well-supported by Packet Tracer 5.0:
Concept-builders (model-building inquiries leading to student-created explications and animations of networking concepts)
Skill-builders (algorithmic problem solving in support of the development of networking procedural knowledge)
Design challenges (constraint-based problems with multiple correct solutions)
Troubleshooting challenges (diagnosing, isolating, and fixing the simulated network from a previously bugged network file)
Packet Tracer 5.0 allows activity authoring for approximately 75% of the topics and skills required for[url=http://www.ccna.cc/]CCNA Certification.[/url]Although the program includes some activities, we strongly encourageyou to share activities that you create with others in the [url=http://www.ccna.cc/]CCNA[/url] teaching and learning community.
