System Priority: This parameter configures the spanning tree priority globally for this
switch. The device with the highest priority becomes the STP root device. However, if
all devices have the same priority, the device with the lowest MAC address will then
become the root device. Number between 0 - 61440 in increments of 4096. Therefore,
there are 16 distinct values.
Hello Time: Interval (in seconds) at which the root device transmits a configuration
message (BPDU frame). Number between 1-10 (default is 2).
Max Age – The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. That also means the
maximum life time for a BPDU frame. Number between 6-40 (default is 20).
Forward Delay: The maximum time (in seconds) the root device will wait before
changing states (i.e., discarding to learning to forwarding). Number between 4–30
(default is 15)
