SMC Networks SMC6924VF manual 2-38, Parameter, Description

USING THE SYSTEM CONFIGURATION PROGRAM

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).
Hold Time	The minimum interval between the transmission of
	consecutive Configuration BPDUs.
Designated Root	The priority and MAC address of the device in the
	Spanning Tree that this switch has accepted as the
	root device.
Root Cost	The path cost from the root port on this switch to the
	root device.
Root Port	The number of the port on this switch that is closest
	to the root. This switch communicates with the root
	device through this port. If there is no root port, then
	this switch has been accepted as the root device of
	the Spanning Tree network.
Reconfig Count	The number of times the Spanning Tree has been
	reconfigured.
Topology Up Time	The time since the Spanning Tree was last
	reconfigured.
