смена мту на стороне А ни к чему не приводит. в чем же проблема?

ведь если бы это была физическая проблема, ошибки быди бы с 2х сторон

[passer]

Если повреждены только несколько пар (или при плохом обжиме), а не все, то ошибки вполне могут быть только на одной стороне.

[YuryD]

Статистика ни о чем. Last clearing of "show interface" counters never. Очистите счетчики, затем сравнивайте.
