3750G-12S проблема

[vaz02 467]

Ошибка на порту, появляются битые пакеты и порт их отбрасывает, в связи с этим появляются пропадания на линиях. Кто сталкивался? Чем полечилось. Прошивка вроде как последняя, СФП стоят ТКО 5 км. Мозга уже не осталось

Ошибки бывают разные.

Ну во первых покажите:  sh int 

так же:

где то так:

FCS-Err это ошибки на физике.

диагноз все тот же
