link-flapping MES2324B

[Artem_V]

Здравствуйте,
имеется цепочка из 6 коммутаторов MES2324B, участки между коммутаторами от 45 до 80 км.
В коммутаторы установлены SFP трансиверы (Eltex) на 160км (CWDM-SFP-G-41-147 D160 Tx1470).

по всем стыкам не удается установить подключение, коммутаторы выключат порты из-за link-flapping.

Подскажите из-за чего может наблюдаться такое поведение ?

Спасибо.
