Enabling BPDU Guard Globally

You can enable BPDU Guard globally by default. In this condition, the system shuts down an edge port that
receives a BPDU.
We recommend that you enable BPDU Guard on all edge ports.
Note
Before You Begin
• Ensure that you are in the correct VDC (or enter the switchto vdc command).
• Ensure that STP is configured.
• Ensure that you are configuring the ports correctly to the device to which the port is connected.
