This example shows how to configure the Ethernet access interface 1/4 to be a spanning tree edge port:
switch# config t
switch(config)# interface ethernet 1/4
switch(config-if)# spanning-tree port type edge
switch(config-if)# exit
switch(config)#

Configuring Spanning Tree Network Ports on Specified Interfaces

You can configure spanning tree network ports on specified interfaces.
Bridge Assurance runs only on spanning tree network ports.
This command has three states:
• spanning-tree port type network—This command explicitly configures the port as a network port. If
• spanning-tree port type normal —This command explicitly configures the port as a normal spanning

Configuring Spanning Tree Network Ports on Specified Interfaces
Purpose
Specifies the interface to configure, and enters
the interface configuration mode.
Configures the specified access interfaces to be
spanning edge ports. 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.
Exits interface configuration mode.
(Optional)
Displays the STP configuration including the STP
port type if configured.
(Optional)
Copies the running configuration to the startup
configuration.
