B.The access port ignores any received BPDU.
C.If the port receives a BPDU， it is placed into the error-disable state.
D.BPDU guard is only configured globally and the BPDU filter is required for port-level configuration.
A.STP will be disabled on the port.
B.PortFast can also be configured on trunk ports.
