spanning-tree bpdufilter

Description
To enable bridge protocol data unit (BPDU) filtering on the interface, use the
spanning-tree bpdufilter command in interface configuration mode. To return to the
default settings, use the negative form of this command.
spanning-tree bpdufilter {disable | enable}
no spanning-tree bpdufilter
Parameter
None
Default
Disabled
Instruction
In SSTP/PVST mode, if a port that configured BPDU Filter and Port Fast receives
BPDU, the BPDU Filter and Port Fast characteristics on that port will be disabled
automatically to restore the port to an ordinary port. Then this port must endure the
wait from Listening to Learning before entering Forwarding state.
This feature is invalid in RSTP/MSTP mode.
