Configuring Spanning Tree STP Security Configurations Step 8 spanning-tree bpduflood (Optional) Enable BPDU Forward. This function only takes effect when the spanning tree function is disabled globally. By default, it is enabled. With BPDU forward enabled, the port can still forward spanning tree BPDUs when the spanning tree function is disabled. Step 9 show spanning-tree interface-security [ fastEthernet port | gigabitEthernet port | tengigabitEthernet port | port-channel port-channel-id ] [ bpdufilter | bpduguard | bpduflood | loop | root | tc ] (Optional) View the protect inforamtion of ports. port: Specify the port number. lagid: Specify the ID of the LAG. Step 10 end Return to privileged EXEC mode. Step 11 copy running-config startup-config Save the settings in the configuration file.
