ThedisputedBPDUthresholdisanintegervariablethatrepresentsthenumberofdisputed

port/SIDuntiladisputedBPDUtrapissentandasyslog

messageisissued.Forexample,ifthethresholdis10,thenatrapisissuedwhen10,20,30,andso

Ifthevalueis0,trapsarenotsent.Thetrapindicates

port,SIDandtotalDisputedBPDUcount.

Thedefaultis0.
