Use this command to enable the BPDU (Bridge Protocol Data Unit) Guard feature on a bridge. Use the
no parameter with this command to disable the BPDU Guard feature on a bridge.


Command Syntax

spanning-tree edgeport bpdu-guard
no spanning-tree edgeport bpdu-guard


Command Mode

Global configuration

Default

Usage

When the BPDU Guard feature is set for a bridge, all edgeport-enabled ports of the bridge that have
the BPDU guard set to default shut down the port on receiving a BPDU. In this case, the BPDU is not
processed. You can either bring the port back up manually by using the no shutdown command, or
configure the errdisable-timeout feature to enable the port after the specified time interval.
Use the show spanning-tree command to display the bridge and port configurations for the BPDU
Guard feature. It shows both the administratively configured and currently running values of BPDU
guard.


Examples

Switch# configure terminal

Switch(config)#
