Re: cam timer tuning

What makes you believe that the difference has anything to do with it ?
Specially after (correctly) infering that TC is causing the flooding!

TC means a MAC could be now anywhere else (from a switch standpoint) so
I guess the solution to your problem (flooding) is to get rid of STP :)
