Я могу ошибаться, но этим правилом вы как раз и убиваете запросы igmp от клиентов - поэтому и нет подписок на группы
Попробуйте выключить это правило или удалить igmp_query из правила
И проверьте соответствие версии IGMP на приставках
igmp_query disable не даёт абонентам выступать в качестве igmp-маршрутизаторов. Так что это не то.
Приставок нет. Есть оболочка VLC на компьютере. Т. е. программа. Поток-то на компьютер приходит!!! Проблема в том,что коммутатор не отображает это в таблицах IGMP Snooping Group и IGMP Snooping Forwarding.
P.S. Иногда отображает.Сегодня утром включил IPTV-player на компьютере. Зашел на коммутатор, посмотрел - IGMP Snooping Forwarding Table пусто!
Ушел из дома на весь день. Настройки никто не менял в течении этого дня 100 % !!! Плеер работал весь день.
Пришел домой вечером. Зашел на коммутатор - IGMP Snooping Forwarding Table говорит, что есть подписка на канал. Удивился и обрадовался. Пробую переключать каналы на плеере - изображение или дико тормозит, или сыпется, или вообще не идёт поток. Может идти нормальное изображение в течении нескольких минут, но потом всё равно замирает на несколько секунд. В таблице IGMP Snooping Forwarding Table в этот момент отображается подписка на другой канал (с чего вдруг?) В таблице подписка на новый канал отображается через раз.
Привожу конфигурацию коммутатора в данный момент (с небольшими сокращениями, т.к. нельзя больше 60000 символов):

Обращаю ваше внимание на
Код:
config multicast port_filtering_mode 1-50 forward_unregistered_groups
Если сказать коммутатору filter_unregistered_group, то (в момент, когда IGMP Snooping Forwarding Table пустая) он вообще ничего не пропускает и весь мультикаст фильтруется
Одним словом, коммутатор ведёт себя абсолютно рандомно. Кто виноват, и что делать?
