 День добрый
 
 Коллеги,
 Hе сталкивался ли кто с подобной проблемой:
 Есть 7206 NSE-1 c модулем PA-4E1G на борту:

 После 2-х месяцев нормальной  работы, начались чудеса. Сначала два-три 
 раза в день циска клала и поднимала поток:

 При этом с физикой все нормально, loop который я ставил в сторону 
 оператора, оператором был увиден и по sh controllers DCD=UP.
