Command Manual (For Soliton) – MSTPH3C S3100 Series Ethernet Switches Chapter 1 MSTP Configuration Commands1-231.1.20 stp edged-portSyntaxstp edged-port { enable | disable }undo stp edged-portViewEthernet port viewParametersenable: Configures the current Ethernet port as an edge port.disable: Configures the current Ethernet port as a non-edge port.DescriptionUse the stp edged-port enable command to configure the current Ethernet port as anedge port.Use the stp edged-port disable command to configure the current Ethernet port as anon-edge port.Use the undo stp edged-port command to restore the current Ethernet port to itsdefault state.By default, all Ethernet ports of a switch are non-edge ports.An edge port is a port that is directly connected to a user terminal instead of anotherswitch or shared network segment. Rapid transition to the forwarding state is applied toedge ports because on these ports no loops can be incurred by network topologychanges. You can enable a port to turn to the forwarding state rapidly by setting it to anedge port. And you are recommended to configure the Ethernet ports directlyconnected to user terminals as edge ports to enable them to turn to the forwarding staterapidly.Normally, configuration BPDUs cannot reach an edge port because the port is notconnected to another switch. But when the BPDU guard function is disabled on anedge port, configuration BPDUs sent deliberately by a malicious user may reach theport. If an edge port receives a BPDU, it turns to a non-edge port.Related commands: stp interface edged-port.
