This is a log from Ciena 3930 switch that's connected to other 3930 using 2 UTP cable and LACP enable. We suddenly get this log 2 days ago although there's no physical or logical change to both UTP cables, it's just happen so sudden. And the link is down between the 2 switched.

 

Does anyone know what causes this problem and how to mitigate this?

 

Thank you
