Configuring STP Extensions

Procedure

	Command or Action	Purpose
Step 1	switch# configure terminal	Enters configuration mode.
Step 2	switch(config)# spanning-tree	Configures all interfaces as edge ports. This assumes all ports are
	port type edge default	connected to hosts/servers. Edge ports immediately transition to
		the forwarding state without passing through the blocking or
		learning state at linkup. By default, spanning tree ports are normal
		port types.
Step 3	switch(config)# spanning-tree	Configures all interfaces as spanning tree network ports. This
	port type network default	assumes all ports are connected to switches and bridges. If you
		enable Bridge Assurance, it automatically runs on network ports.
		By default, spanning tree ports are normal port types.
		Note	If you configure interfaces connected to hosts as network
			ports, those ports automatically move into the blocking
			state.

This example shows how to configure all access and trunk ports connected to hosts as spanning tree edge ports:

switch# configure terminal

switch(config)# spanning-tree port type edge default

This example shows how to configure all ports connected to switches or bridges as spanning tree network ports:

switch# configure terminal

switch(config)# spanning-tree port type network default

Configuring Spanning Tree Edge Ports on Specified Interfaces

You can configure spanning tree edge ports on specified interfaces. Interfaces configured as spanning tree edge ports immediately transition to the forwarding state, without passing through the blocking or learning states, on linkup.

This command has four states:

•spanning-tree port type edge—This command explicitly enables edge behavior on the access port.

•spanning-tree port type edge trunk—This command explicitly enables edge behavior on the trunk port.

Note If you enter the spanning-tree port type edge trunk command, the port is configured as an edge port even in the access mode.

•spanning-tree port type normal—This command explicitly configures the port as a normal spanning tree port and the immediate transition to the forwarding state is not enabled.
