высокий показатель MLR

[3dimension]

Добрый день!
На канале L2vpn при тестировании анализатором выявлены проблемы с multicast трафиком, высокий показатель MLR. На оконечке установлен коммутатор MES2324, на физическом уровне потерь не выявлено. Может Элтекс влиять на MLR, и поможет в данном случае настройка qos и увеличение буферов выходных очередей?

Конфиг интерфейсов простейший

interface tengigabitethernet1/0/4

switchport trunk allowed vlan add 3439,3690
switchport forbidden default-vlan
exit

Здравствуйте.

Прошу включить
qos stat int
зафиксировать проблему с потерями и показать выводы

Здравствуйте.

Дропов в буферах нет, а вот ошибки есть на te0/3
gdmnt-sw1#sh int te0/3
73 input errors, 69 FCS, 0 alignment
Предположительно связаны с физикой.
