Spanning-Tree Portfast Bpdu-Filter - Allied Telesis SwitchBlade x908 Series Software Reference Manual

spanning-tree portfast bpdu-filter

This command sets the portfast feature and applies a filter to any BPDUs received. Enabling this
feature ensures that PortFast configured ports will not transmit any BPDUs and will ignore
(filter out) any BPDUs received.
Using the no parameter variant of this command will turn off the bpdu-filter, but retain the
port's status a portfast. If the port then receives a BPDU it will change its role from an edge-
port to a non edge-port.
