Приветствую. Не могу победить аггрегацию портов на A28E. Коммутатор лупит броадкаст пакеты в транке. Разные A28E, подключены к разным коммутаторам (Dlink, SNR) симптомы одинаковые. Текущая конфигурация:

Как только включаю второй порт, в дампе начинается флуд таких пакетов, данный мак начинает светиться на транковых портах.

В мануал режиме то же самое. То же самое с на стыке с SNR. Есть подозрение, что это какой то волшебный не стандартный dhcp запрос, или же я не дочитал мануалы по настройке, кто-нибудь сталкивался?
