2. Usage:
Use this command to enable the BPDU (Bridge Protocol Data Unit) Guard feature on a bridge.
Use the no parameter with this command to disable the BPDU Guard feature on a bridge.
When the BPDU Guard feature is set for a bridge, all portfast-enabled ports of the bridge that have bpdu-guard set to default
shut down the port on receiving a BPDU. In this case, the BPDU is not processed.
3. Command Syntax:
bridge GROUP spanning-tree portfast bpdu-guard
no bridge GROUP spanning-tree portfast bpdu-guard
GROUP <1-1> Bridge-group ID used for bridging.
4. Example:
The following example enables the BPDU Guard feature on bridge GROUP (1):
switch_a(config)#bridge 1 spanning-tree portfast bpdu-guard
switch_a(config)#
