This example shows how to explicitly enable BPDU Guard on the Ethernet edge port 1/4:
switch# config t
switch(config)# interface ethernet 1/4
switch(config-if)# spanning-tree bpduguard enable
switch(config-if)# exit
switch(config)#
Description

specified spanning tree edge interface. By
default, BPDU Guard is disabled on the
interfaces.
Falls back to the default BPDU Guard
global setting that you set for the interfaces
by entering the spanning-tree port type
edge bpduguard default command.
