Имеется CISCO C3750, в который в порт-канал приходит IPTV, и цепочка d-link des3028 которая воткнута в циску. Картинка ТВ ужасно сыпется. Пробовал настраивать по офф мануалам и мануалам интузиастов, но из-за не знания английского языка, а может и из-за кривизны рук ничего настроить так и не получилось.
Прошу помощи.Из конфига циски:

В длинках ACL'ом повышается приоритет к пакетам с метками DSCP 32
ТЫ судя по статистике приходит с метками DSCP 48:

Вот только с очередями я не разобрался и не понял.
В теории все правильно и картинка не должна сыпаться, но сыпется.
Если с циской все в норме, покажу конфиг длинка.
В длинке для мультика заведен ISM влан.
Прошу помощи!
