STP - BPDU generation and port roles


When [STP](/spanning-tree-protocol-stp) is [disabled](/stp-disabling-spanning-tree) on a particular [VLAN](/vlan), any [BPDUs](/stp-bpdu-types) received are forwarded like other multicast frames.  No BPDUs are generated by the switch interfaces on that particular VLAN.
