Configuring Protected Ports
TheProtectedPortfeatureisusedtopreventportsfromforwardingtraffictoeachother,even
whentheyareonthesameVLAN.Portsmaybedesignatedaseitherprotectedorunprotected.
Portsareunprotectedbydefault.Multiplegroupsofprotectedportsaresupported.
Protected Port Operation
Portsthatareconfiguredtobeprotectedcannotforwardtraffictootherprotectedportsinthe
samegroup,regardlessofhavingthesameVLANmembership.However,protectedportscan
forwardtraffictoportswhichareunprotected(notlistedinanygroup).Protectedportscanalso
forwardtraffictoprotectedportsin
adifferentgroup,iftheyareinthesameVLAN.Unprotected
portscanforwardtraffictobothprotectedandunprotectedports.Aportmaybelongtoonlyone
groupofprotectedports.
Thisfeatureonlyappliestoportswithinaswitchorastack.Itdoesnotapplyacrossmultiple
switchesinanetwork.
