A bridge protocol data unit (BPDU) was received on an interface that has the spanning
Explanation
tree BPDU guard feature enabled. As a result, the interface was administratively shut down. [chars]
is the interface name.
Either remove the device sending BPDUs, or disable the BPDU guard feature.
Recommended Action
The BPDU guard feature can be locally configured on the interface or globally configured on all
ports that have PortFast enabled. To disable BPDU guard on an interface, use the no spanning-tree
bpduguard enable interface configuration command. To disable BPDU guard globally, use the no
spanning-tree portfast bpduguard default global configuration command. After you have
removed the device or disabled BPDU guard, re-enable the interface by entering the no shutdown
interface configuration command.
Explanation A bridge protocol data unit (BPDU) was received on the interface and VLAN specified
in the error message. The spanning tree BPDU guard feature was enabled and configured to shut
down the VLAN. As a result, the VLAN was placed in the error-disabled state. [chars] is the
interface, and [dec] is the vlan.
Either remove the device sending BPDUs, or disable the BPDU guard feature.
Recommended Action
The BPDU guard feature can be locally configured on the interface or globally configured on all
ports that have Port Fast enabled. Re-enable the interface and vlan by entering the clear errdisable
privileged EXEC command.
