ThedisputedBPDUthresholdisanintegervariablethatrepresentsthenumberofdisputed
BPDUsthatmustbereceivedonagiven
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
