Parameter Description
Priority Device priority is used in selecting the root device, root port, and
designated port. The device with the highest priority becomes the STA root
device. However, if all devices have the same priority, the device with the
lowest MAC address will then become the root device.
Hello Time The time interval (in seconds) at which the root device transmits a
configuration message.
Max Age The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure.
Forward Delay The maximum time (in seconds) the root device will wait before changing
states (i.e., listening to learning to forwarding).
