FILTER
spanning-tree portfast bpdu-filter
Overview This command sets the bpdu-filter feature and applies a filter to any BPDUs (Bridge
Protocol Data Units) received. Enabling this feature ensures that configured ports
will not transmit any BPDUs and will ignore (filter out) any BPDUs received. BPDU
Filter is not enabled on a port by default.
Using the no variant of this command to turn off the bpdu-filter, but retain the
port’s status as an enabled port. If the port then receives a BPDU it will change its
role from an
edge-port to a non edge-port .

port. Using this command in Global Configuration mode applies the portfast
bpdu-filter feature to all ports on the device. Using it in Interface mode applies the

and MSTP networks.
Use the show spanning-tree command to display status of the bpdu-filter
parameter for the switch ports.
Example To enable STP BPDU filtering in Global Configuration mode, enter the commands:
awplus# configure terminal
awplus(config)# spanning-tree portfast bpdu-filter
