Cisco Catalyst 2960-X MacFlap

Hi I have been receiving MACFLAP errors on a couple of our Cisco switches, can anyone give me an idea to pinpoint the problem? I will insert an images from the 2 switches showing the log entries.  Thank you.  - BillCatalyst 3750-XCatalyst 2960-X

99.9% of the time, this is caused by a loop.  Spanning Tree is supposed to prevent loops but if you have some equipment that isn't running STP or is running a different type of STP, then a loop could result.

Can you post a topology diagram and the output of a "show span" from the Cisco switches?
