What firmware is the switch running on?
What happens if you run a TDR?

The port in question is Gi1/0/18 and the TDR is done on Gi1/0/8. :P

Juan C. Pineda · ‎09-11-2019

you are right :P , I´m sorry:

Note: the log disappeared when i set the line "power inline never" on the interface g1/0/18, but I want to know the root cause.

Leo Laohoo · ‎09-11-2019

The cable nearest the switch is faulty.
