SMC Networks SMC8606T manual Console Interface

		CONSOLE INTERFACE
Parameter	Default	Description
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	20	The maximum time (in seconds) a device
(Message)		can wait without receiving a configuration
Age		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	15	The maximum time (in seconds) the root
Delay		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].
