Default
BPDU guard is not configured on a per-edge port basis. The status of BPDU guard on an interface is
the same as the global BPDU guard status.

Parameters
: Enables BPDU guard.
enable
: Disables BPDU guard.
disable
Usage guidelines
With BPDU guard enabled, the device performs the following operations when an edge port receives
configuration BPDUs:
•
Shuts down the port.
•
Notifies the NMS that the port has been shut down by the spanning tree protocol.
The device reactivates the port that has been shut down when the port status detection timer expires.
You can set this timer by using the
this command, see device management commands in Fundamentals Command Reference.
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.
If this command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
If this command is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
If this command is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.
