Содержание


Введение

В этом документе предлагается образец конфигурации для удаленных пользователей, выполняющих вызов с помощью одного из следующих методов. В каждом случае обратный вызов осуществляется с помощью вызова V.110.

  • Пользователи, подключающиеся к 3640 посредством GSM и запрашивающие обратный вызов.

  • Пользователи, подключающие 3640 через модем и запрашивающие обратный вызов.

  • Пользователи, подключающие 3640 через ISDN (данные) и запрашивающие обратный вызов.

Примечание: Аутентификация, авторизация и учет (AAA) настроена на маршрутизаторе по умолчанию. Необходимо также создать пользователя для входа в систему.

В данном примере мы также установили аутентификацию Протокола PPP для вызова и выноски. Мы изменили сценарий, чтобы настроить модем для V.110 все время и позволить пользователям выбирать свой метод (модем или GSM). В зависимости от выбранного способа должны пользователи:

  • используйте ZDTxxx в номере обратного вызова (для модема).

  • используйте DIxxxx в номере обратного вызова (для GSM).

Предварительные условия

Требования

Для этого документа отсутствуют особые требования.

Используемые компоненты

Сведения, содержащиеся в данном документе, касаются следующих версий программного и аппаратного обеспечения:

  • Характеристика обратного вызова V.110 доступна на IOS Розы?? Выпуск ПО 12.2 (5.2) T и выше.

  • Программное обеспечение модема версии 2.7.3.0.

Сведения, представленные в этом документе, были получены от устройств, работающих в специальной лабораторной среде. Все устройства, описанные в этом документе, были запущены с чистой (стандартной) конфигурацией. В рабочей сети необходимо изучить потенциальное воздействие всех команд до их использования.

Условные обозначения

Дополнительные сведения об условных обозначениях в документах см. Cisco Technical Tips Conventions.

Настройка

В этом разделе содержатся сведения о настройке функций, описанных в этом документе.

Примечание: Дополнительные сведения о командах, используемых в данном документе, можно получить с помощью средства поиска команд (только для зарегистрированных клиентов).

Проверка.

В данном разделе содержатся сведения о проверке работы конфигурации.

Некоторые команды show поддерживаются Средством интерпретации выходных данных(только зарегистрированные клиенты), которое позволяет просматривать аналитику выходных данных команды show.

  • show ip route??? отображает содержание таблицы IP-маршрутизации

Устранение неполадок

В этом разделе описывается процесс устранения неполадок конфигурации.

Примечание: Перед запуском команд отладки обратитесь к разделу Важные сведения о командах отладки.

  • debug modem – наблюдать операции линии модема относительно сервера доступа.

  • debug dialer events — вывод отладочной информации о пакетах, полученных в интерфейсе номеронабирателя.

  • команда "debug ppp authentication" отображает сообщения протокола проверки подлинности, включая информацию об обмене пакетами протокола проверки подлинности запроса CHAP и обмене по протоколу проверки подлинности по паролю (PAP).

  • debug ppp cbcp — ошибки протокола показов и статистика связались с согласованиями PPP - подключения с помощью Протокола управления управления обратными вызовами Microsoft (MSCB)..

  • "debug isdn q931" - отображение сведений об установлении соединения и освобождении канала в сети ISDN (третий уровень модели OSI) между локальным маршрутизатором (на стороне пользователя) и сетью.

  • debug chat – , что сценарий диалогового взаимодействия функционирует должным образом.

  • debug callback — события обратного вызова показов, когда маршрутизатор использует модем и сценарий диалогового взаимодействия к обратному вызову на абонентской линии.
