Гораздо мощнее, чем Bosson NetSim в подготовке к экзаменам.
С помощью PT 4.0 учителя и студенты могут создавать, конфигурить и заниматься отладкой сети в виртуальной среде. Доступно оборудование Cisco Systems.
Можно:
-Симулировать локальную сеть с использованием маршрутизаторов, свитчей, точек доступа и т.п.
-Большой выбор различных конфигураций сетевого оборудования Cisco. Много описаний модулей.
-Симуляция командной строки.
-симуляция отладки
-Визуальная симуляция хождения пакетов в сети.
Внутри модули для CCNA.
Packet Tracer simulation software can be used to teach complex CCNA-level networking concepts and to supplement classroom equipment. With PT4.0, instructors and students can design, build, configure, and troubleshoot networks using virtual equipment.It provides a common environment for instructors to demonstrate technologies and configurations, making it extremely useful for lectures, group and individual labs, homework, and competitions. Students can use PT4.0 to explore concepts, conduct experiments, and test their understanding.
PT4.0 includes the following features:
* Logical topology mode: Primary workspace for creating networks of any size at a CCNA-level of complexity
* Real-time mode: Now models real-time protocol updates
* Simulation mode: Global packet sniffer allows for detailed study of protocol interactions with in-depth display of network details.
* Physical topology mode: More intuitive interaction with physical devices, with physical layout and distance representation including city, building, and rack views
* Improved GUI: Increased student understanding of networking fundamentals with device tables and numerous means of annotation
* Multiple-language support: Instructions included for translation into other languages by any end user or group
* Refined physical interfaces: Models realistic equipment set up including adding and removing components
* Knowledge representations: Offers discovery learning by enabling "what if?" scenarios using simulation-mode visualization features that allow students to freeze time
* Activity Wizard improvements: Instructors and students can easily create and share network templates and assessment activities.
