Usage Guidelines To enable BPDU Guard by default, you must do the following:
• Configure the interface as spanning tree edge ports by entering the spanning-tree port type edge
or the spanning-tree port type edge default command.
• Enable BPDU Guard.
Use this command to enable BPDU Guard globally on all spanning tree edge ports. BPDU Guard disables
a port if it receives a BPDU.
Global BPDU Guard is applied only on spanning tree edge ports.
You can also enable BPDU Guard per interface; see spanning-tree bpduguard command for more
information.
Note We recommend that you enable BPDU Guard on all spanning tree edge ports.
