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.Itdoesnotapplyacrossmultipleswitchesina
network.
