Usage
AdisputedBPDUisoneinwhichtheflagsfieldindicatesadesignatedroleandlearning,andthe
priorityvectorisworsethanthatalreadyheldbytheport.IfadisputedBPDUisreceivedtheport
isforcedtothelisteningstate.Refertothe802.1Q‐2005standard,IEEEStandard

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.
