HighErrorRate на интерфейсах,

Babaich, 09-Мрт-09, 15:53 [смотреть все]

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.

Поставил MTU 9216, но ситуация осталась прежней. Giant-пакеты продолжают составлять 15-20% трафика.

>с физикой точно всё ОК?
Вроде да. СКС по проекту тестировалась. Результаты нормальные. И ведь это не на одном каком-то линке.

На всех портах которые скоммутированы в пользовательские (С2950) и серверные (С3750) свитчи. Порты с маршрутизаторами или серверами без giant(практически все четные).
