AdisputedBPDUisoneinwhichtheflagsfieldindicatesadesignatedroleandlearning,andthe

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
on,disputedBPDUshavebeenreceived.
Ifthevalueis0,trapsarenotsent.Thetrapindicates
port,SIDandtotalDisputedBPDUcount.
Thedefaultis0.
