How BPDU filtering works, if applied globally or if applied on interface?

When enabled globally, BPDU filtering has these attributes:
*It affects all operational PortFast ports on switches that do not have BPDU filtering configured on the individual ports.
*If BPDUs are seen, the port loses its PortFast status, BPDU filtering is disabled, and the STP sends & receives BPDUs on the port as it would with any other STP port on the switch.
*Upon startup, the port transmits ten BPDUs. If this port receives any BPDUs during that time,PortFast and PortFast BPDU filtering are disabled.

When enabled on an individual port, BPDU filtering has these attributes:
*It ignores all BPDUs received.
*It sends no BPDUs.
