switch(config)# interface ethernet 1/4
switch(config-if)# spanning-tree bpduguard enable
switch(config-if)# exit
switch(config)#
Command or Action
config t
Example:
switch# config t
switch(config)#

Enables or disables BPDU Guard for the
specified spanning tree edge interface. By
default, BPDU Guard is disabled on the
interfaces.
• no spanning-tree bpduguard
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.
Exits interface mode.
