не работает нормально igmp2 а именно leave пакетики не обрабатываются на свиче, прошивка 3.05-B09

трафик попёр смотрю канал!

Трафик как пёр так и прёт:

состояние порта - мой порт принадлежит группе 239.255.0.10
и только по истечению времени
а именно отсутствия report пакета трафик перестаёт идти...

Пожалуйста оттестите этот случай мы не можем предоставлять в этом случае телевидение через АДСЛ2, потому что канал буквально моментально забивает - посл того как пользователь пошёлкает по каналам...

Для начала попробуйте перепрошить коммутатор прошивкой 3.06-B20

нифига не помогла прошивка
лив почему то не отрабатывается
настроено всё как сказано в часто задаваемых вопросах
и так далее

Что тут не так сделано? Помогите пожалуйста!

А Вы не могли бы поподробнее и на почту? Конфиг файл, схема сети, дамп в формате Ethereal, если необходимо. Обязательно разберёмся

ок схему сети я высылаю Вам на почту, на support@dlink.ru
ну с конфигами думаю понятно я их выше приводил, вроде бы всё правильно выставлено, если нет - ткните носом...

Нам чтобы провести тесты нужны именно ваши конфиг-файлы, слитые по tftp. И пожалуйста вышлите это всё на idemin@dlink.ru

Извините что не в тему, скажите вы dwl-7700ap используете, или отказались от них?
