Вставки в обоих картах XENPAK-10GB-CX4 (медь, подключены через родной медный кабель)

Интересуют такие вопросы.
1. Откуда берутся ошибки на интерфейсах (121 input errors, 85 CRC, 85 frame), "живого" трафика на них нет
2. Как можно посмотреть из IOS'a качество кабеля (например как TDR тест на 1gbps меди)
3. Может есть что-то хитроумное и тонкое в конфигурировании 10gbps порта?
