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

receives a BPDU.
Note We recommend that you enable BPDU Guard on all edge ports.
Before You Begin
Ensure that STP is configured.
Ensure that you have configured some spanning tree edge ports.
