PortFast parameters for the port channel's MSTP configuration:
PortFast reduces the time required for a port to complete a MSTP state change from
Blocked to Forward. PortFast must only be enabled on ports on the wireless controller
directly connected to a server/workstation and not another hub or controller. PortFast can
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.
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.
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
are processed. The default setting is None.
Reset to revert to the last saved configuration.
