This determines how BPDU packets are managed when STP is
disabled on the port/ device. BPDUs are used to transmit spanning

• Filtering, where filters BPDU packets when spanning tree is
disabled on an interface. This is the default value.
•
Flooding, where floods BPDU packets when spanning tree is
disabled on an interface.
This specifies the method used to assign default path costs to STP
ports. The possible field values are:
