Здраувствуйте!Возникла необходимость для создания port-channel на коммутаторах 3750 и 3560.
На нескольких коммутаторах port-channel заработал успешно. Стали настраивать по аналогии на следующих коммутаторах и не ничего не выходит. Пишет: line protocol is down (suspended). При одинаковых конфигах порты не работают. Прошу помочь и понять в чем причина.
Конфиг "рабочего" коммутатора:

Пробовали явно прописать LaCP на интерфейсах, пробовали: switchport mode trunk,switchport nonegotiate. Ни чего не вышло.
