17.6 Настройка G.8032
16.7.1 Обзор
Ethernet-кольца могут обеспечивать широкополосное многоточечное подключение более экономично благодаря уменьшенному количеству соединений. Каждый узел кольца подключается к соседним узлам, участвующим в том же кольце, через два независимых канала. Связь между двумя узлами кольца называется линком кольца, а порт для такого линка называется кольцевым портом. Минимальное количество узлов в кольце — два.
Основы архитектуры защиты колец включают:
- Принцип предотвращения петель.
- Использование механизмов обучения, пересылки и таблиц адресов, определённых в функции пересылки потоков Ethernet (ETH_FF).
Предотвращение петель достигается за счёт гарантии того, что трафик может передаваться по всем линкам кольца, кроме одного. Этот конкретный линк называется линком защиты кольца (RPL), и в нормальных условиях он блокирован, т.е. не используется для передачи трафика. Ответственность за блокировку трафика через RPL несёт один из узлов, называемый владельцем RPL (RPL Owner). В случае отказа в кольце владелец RPL обязан разблокировать RPL, чтобы использовать его для передачи трафика.
В случае отказа в кольце происходит переключение на защиту трафика, которое осуществляется под управлением функций ETH_FF на всех узлах кольца.
Для координации действий защиты по кольцу используется протокол APS.

17.6.6 Связь между G8032 и CFM
Существуют два способа инициировать переключение защиты G.8032:
- Инициирование в результате состояния
linkdown/shutdownинтерфейса. - Инициирование через CFM.
Примеры конфигурации приведены ниже:
