Usage guidelines
With BPDU guard enabled, the device performs the following operations when edge ports receive
configuration BPDUs:
•
Shuts down these ports.
•
Notifies the NMS that these ports have been shut down by the spanning tree protocol.
The device reactivates the ports that have been shut down when the port status detection timer
expires. You can set this timer by using the
shutdown-interval
command. For more information
about this command, see device management commands in Fundamentals Command Reference .
The global BPDU guard setting takes effect on all edge ports configured by using the
stp
edged-port
command.
You can configure the BPDU guard feature globally or on a per-port basis. A port preferentially uses
the port-specific BPDU guard setting. If the port-specific BPDU guard setting is not available, the port
uses the global BPDU guard setting.
Examples

stp bridge-diameter
Use
stp bridge-diameter
to set the network diameter. The switched network diameter refers to
the maximum number of devices on the path for an edge device to reach another through the root
bridge.
Use undo stp bridge-diameter to restore the default.
