be left unconfigured on an access point.
Select this option to enable drop-down menus for both the Enable PortFast BPDU Filter
and Enable PortFast BPDU Guard options. This setting is disabled by default.
PortFast BPDU Filter Select Enable to invoke a BPDU filter for this PortFast enabled port channel. Enabling the
BPDU filter feature ensures this port channel does not transmit or receive any BPDUs. The
default setting is None.
PortFast BPDU Guard Select Enable to invoke a BPDU guard for this PortFast enabled port channel. Enabling the
BPDU Guard feature means this port will shutdown on receiving a BPDU. Thus, no BPDUs

can isolate devices to prevent connectivity over this port channel. This setting is
disabled by default.
