Здравствуйте,Имеется две С6506 в качестве ядра. И несколько серверных свитчей С3750. Все порты Gigabit. Каждый С3750 смотрит 2 портами объединенными в portchannel на каждый С6506. Т.е. треугольник. В качестве spanning-tree указан rapid-pvst.
Проблема: Cisco LMS постоянно гундосит:

Может ли это как-то быть связанным с большим количеством giants-пакетов?
Если да, то что подкрутить, чтоб избавиться?
Спасибо.
