Enterasys Networks VH-2402S manual Device with the lowest MAC address will then

Parameter	Default	Description
Spanning Tree	Enabled	Enable this parameter to participate in an STA
Protocol		compliant network.
Priority	32,768	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.
		Enter a value from 0 - 65535.
		Remember that the lower the numeric value, the
		higher the priority.
Hello Time	2	Time interval (in seconds) at which the root device
		transmits a configuration message.
		The minimum value is1.
		The maximum value is
		the lower of 10 or [(Max. Message Age / 2) -1].
Max (Message) Age	20	The maximum time (in seconds) a device can wait
		without receiving a configuration message before
		attempting to reconfigure. All device ports (except
		for designated ports) should receive configuration
		messages at regular intervals. Any port that ages
		out STA information (provided in the last
		configuration message) becomes the designated
		port for the attached LAN. If it is a root port, a new
		root port is selected from among the device ports
		attached to the network.
		The minimum value is
		the higher of 6 or [2 x (Hello Time + 1)].
		The maximum value is
		the lower of 40 or [2 x (Forward Delay - 1)].
Forward Delay	15	The maximum time (in seconds) the root device
		will wait before changing states (i.e., listening to
		learning to forwarding). This delay is required
		because every device must receive information
		about topology changes before it starts to forward
		frames. In addition, each port needs time to listen
		for conflicting information that would make it
		return to a blocking state; otherwise, temporary
		data loops might result.

The maximum value is 30. The minimum value is

the higher of 4 or [(Max. Message Age / 2) + 1].
