spanning-tree bpdu-guard
Use this command to enable or disable the BPDU Guard feature on a port.
This command supersedes the bridge level configuration for the BPDU Guard feature. When the enable or disable parameter is used with this command, this configuration takes precedence over bridge configuration. However, when the default parameter is used with this command, the bridge-level BPDU Guard configuration takes effect.
Use the
show spanning tree command to display administratively configured and currently running values of the BPDU filter parameter for the bridge and port (see
show spanning-tree).
Use the no parameter with this command to set the BPDU Guard feature on a port to default.
