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

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

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?
