The lower the setting defined, the greater the likelihood of becoming the root bridge in the spanning tree topology.

Set a BPDU hello interval from 1 - 10 seconds. BPDUs are exchanged
regularly (every 2 seconds by default) and enable supported devices to keep
track of network changes and start/stop port forwarding as required.
Set the forward delay time from 4 - 30 seconds. When a device is first
attached to a port, it does not immediately start to forward data. It first
processes BPDUs and determines the network topology. When a host is
attached the port always goes into the forwarding state, after a delay of
while it goes through the listening and learning states. The time spent in the
listening and learning states is defined by the forward delay (15 seconds by
default).
Use the spinner control to set the maximum time (in seconds) to listen for the
root bridge. The root bridge is the spanning tree bridge with the smallest
(lowest) bridge ID. Each bridge has a unique ID and a configurable priority
number, the bridge ID contains both. The available range is from 6 - 40. The
default setting is 20.
PortFast parameters for the profile configuration:
Select Enable to invoke a BPDU filter for this portfast enabled port. Enabling
the BPDU filter feature ensures this port channel does not transmit or receive
any BPDUs. BPDUs are exchanged regularly and enable the access point to
keep track of network changes and to start and stop port forwarding as
required. The default setting is Disabled.
Select Enable to invoke a BPDU guard for the portfast enabled port. Enabling
the BPDU Guard feature means this port will shutdown on receiving a BPDU.
Thus, no BPDUs are processed. BPDUs are exchanged regularly and enable
the access point to keep track of network changes and to start and stop port
forwarding as required. The default setting is Disabled.
Error Disable settings:
Select this option to enable a error disable timeout resulting from a BPDU
guard. This setting is disabled by default.
Define the recovery interval used to enable disabled ports. The available
range is from 10 - 1,000,000 seconds with a default setting of 300.
