2. Специальная часть
Постановка задачи №1
Добавим на рабочую область программы 2 комутатора Switch-PT. По умолчанию они имеют имена – Switch0 и Switch1.
Добавим на рабочее поле четыре компъютера с именами по умолчанию PC0, PC1, PC2, PC3.
Соединим устройства в сеть Ethernet , как показано на рис.1.4.
Сохраним созданую топологию, нажав кнопку Save (в меню File -> Save).
Откроем свойства устройства PC0 нажав на его изображение.Перейдем к вкладке Desktop и симулируем работу run нажав Command Prompt.
Список команд получим, если введем? и нажмем Enter. Для конфигурирования компьютера воспользуемся командой ipconfig из командной строки, например:
ipconfig 192.168.1.2 255.255.255.0
