SNR-S4350X-48FC потеря трафика

[Fusy]

Добрый день.

Подскажите пжлст куда копать в следующей ситуации.

используются два порта 100G. между портами поднят vlan 300. 

при подаче нагрузки на один порт, на втором видим скорость на 30% ниже.

Тесты проводим с Trex. при постановке железной петли на сервере с Трех потерь нет. при прогоне через коммутатор видим потери.
