Port Type and Link Type
Edge/Portfast Port
Aportthatdoesnotconnecttoabridgeiscalledanedgeport.Sinceedgeportsare 
assumedtobeconnectedtonon‐STPdevices(suchasdirectlytohostsorservers),
theyareplacedintheforwardingstateassoonasthelinkisup.Internalports
(INTx
)shouldbeconfiguredasedgeports.
EdgeportssendBPDUstoupstreamSTPdeviceslikenormalSTPports,butshould
notreceiveBPDUs.IfaportwithedgeenableddoesreceiveaBPDU,it
immediatelybeginsworkingasanormal(non‐edge)port,andparticipatesfullyin
SpanningTree.

Link Type
ThelinktypedetermineshowtheportbehavesinregardtoRapidSpanningTree.
Usethefollowingcommandstodefinethelinktypefortheport:
wheretypecorrespondstotheduplexmodeoftheport,asfollows:
 p2p Afull‐duplexlinktoanotherdevice(point‐to‐point)
 shared Ahalf‐duplexlinkisasharedsegmentandcancontainmore
thanonedevice.
 auto Theswitchdynamicallyconfiguresthelinktype.
Note: AnySTPportinfull‐duplexmodecanbemanuallyconfiguredasashared
portwhenconnectedtoanon‐STP‐awareshareddevice(suchasatypical
Layer2switch)usedtointerconnectmultipleSTP‐awaredevices.
