Configuration? Does this port have other VLANs? What's on the other side?

Hi! thanks for answer, the other side have a OS6560P24X4 is a trunk port, in this side i see the log stp changes, maybe someone is doubling the gateway ??...

STP changes can have a number of reasons, network loops or third party/garbage switches can cause this for example.
