Enabling BPDU Guard on Specified Interfaces

You can enable BPDU Guard on specified interfaces. Enabling BPDU Guard shuts down the port if it receives
a BPDU.
You can configure BPDU Guard on specified interfaces as follows:
• spanning-tree bpduguard enable—Unconditionally enables BPDU Guard on the interface.
• spanning-tree bpduguard disable—Unconditionally disables BPDU Guard on the interface.
• no spanning-tree bpduguard—Enables BPDU Guard on the interface if it is an operational edge port
and if the spanning-tree port type edge bpduguard default command is configured.
Before You Begin
Ensure that STP is configured.
