BPDU guard status example configurations
The following example shows how to configure BPDU guard at the interface level and to verify the
configuration by issuing the show stp-bpdu-guard and the show interface commands.
device(config)#interface ethernet 1
device(config-if-e1000-1)#stp-bpdu-guard
device(config-if-e1000-1)#
device(config-if-e1000-1)#show stp-bpdu-guard
BPDU Guard Enabled on:
Port
1
device(config-if-e1000-1)#
device(config-if-e1000-1)#show interfaces ethernet 1

BPDU guard status example console messages
A console message such as the following is generated after a BPDU guard violation occurs on a system
that is running MSTP.
device(config-if-e1000-23)#MSTP: Received BPDU on BPDU guard enabled Port
23,errdisable Port 23
A console message such as the following is generated after a BPDU guard violation occurs on a system
that is running STP.
device(config)#STP: Received BPDU on BPDU guard enabled Port 23 (vlan=1), errdisable
Port 23
