Всех приветствую.
Столкнулись с такой проблемой:
Через некоторое время (час-полтора) просмотра IPTV канала картинка замирает, через несколько секунд восстанавливается.
Эксперименты выявили, что группа отваливается как на коммутаторе, так и на роутере (Cisco 3550).
Проблема была решена только
отключением ISM VLAN, и запуском IPTV в абонентском VLAN.
Есть у кого мысли с чем это связано?
