В графе "Loss %" статистики потоков на сервере IXIA мы видим порядок обработки трафика в соответствии с весом очередей. Трафик высокоприоритетных очередей 6, 7 и 8 прошел полностью без потерь, утилизировав 900Mb/s пропускной способности интерфейса gi0/1. В очереди 5 потери составили около 70%, что соответствует оставшейся на интерфейсе полосе пропускания в 100Mb/s. Пакеты оставшихся очередей были полностью отброшены.

...

вес очередей оставим таким же, посмотрим на результат:

и начинаем считать.
