Before You Begin
Ensure that STP is configured.
Ensure that the interface is connected to hosts.

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

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.

the edge ports globally, the no spanning-tree port type command is equivalent to the spanning-tree
port type disable command.

Purpose
Enters global configuration mode.
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.
